This document discusses glidants and anticaking agents. It defines glidants as substances added to powders to improve flowability by counteracting factors that cause poor flowability, such as by reducing surface irregularity and friction. Common glidants include magnesium stearate, aerosol, and colloidal silicon dioxide. Anticaking agents are defined as additives that prevent clumping in powders during packaging, transport, and use. They work by strongly adsorbing moisture to compete with moisture absorption by powder particles, thus reducing caking. Common anticaking agents listed are calcium carbonate, magnesium carbonate, and sodium aminosilicate.

Modified atmospheric packaging {MAP}
Packaging has been used for thousands of years, originally using natural materials like skins and leaves. Four thousand years ago, sealed pottery jars were introduced to protect against rodents. One hundred years ago, packaging was rarely used in food industries but now is a significant part of food production, with continuous development of new packaging materials and equipment. Modified atmosphere packaging is a common technique that uses specialized machinery to flush out air and replace it with different gases or gas mixtures to provide longer shelf life and maintain food safety and quality by modifying the normal air composition. The major gases used are nitrogen, oxygen, and carbon dioxide in various combinations depending on the food and storage temperature.
mechanical seperation in food
This document defines mechanical separation and describes the key processes involved. Mechanical separation uses machines to separate mixtures based on differences in density or size/shape. There are four main types of mechanical separation: sedimentation, centrifugal separation, filtration, and sieving. Sedimentation involves settling solids to the bottom of a liquid. Centrifugal separation uses centrifugal force to separate mixtures based on density differences. Filtration passes a solid-liquid mixture through a porous medium to separate insoluble solids. Sieving involves mechanically shaking a sample to separate particles by size as they pass through mesh screens. Mechanical separation is used extensively in food processing due to its ability to efficiently separate materials in a timely manner.
Drying final
This document discusses various drying methods used in pharmaceutical manufacturing. It defines drying as removing liquid from a material through heat transfer and evaporation. Several dryer types are described, including drum dryers, spray dryers, tray dryers, tunnel dryers, rotary dryers, fluidized bed dryers, vacuum dryers, and freeze dryers. Each method is explained along with its advantages and disadvantages. Freeze drying and vacuum drying allow heat-sensitive materials to be dried at low temperatures. Larger dryers like spray dryers and rotary dryers provide continuous high-volume drying.
Edible Packaging
This document discusses edible packaging as an environmentally friendly alternative to traditional plastic packaging. It provides an introduction to edible packaging, explaining why it is needed due to the large amount of non-biodegradable plastic waste. Edible packaging is defined as a thin film or coating that can be consumed as part of the food. Common materials used include proteins, polysaccharides, and lipids. Edible packaging can provide benefits like moisture and gas barriers while being safely edible. However, challenges remain regarding their cost effectiveness and commercialization at scale.
MAILLARD REACTION
Maillard reaction is the mother of all reactions ; Responsible for the characteristics thousands of flavours and appealing colour of majority of food products treated at high temperatures . There are different factors effecting rate of this reaction. Pool of flavours are produced here through a series of complex reactions .Imitating maillard reaction products has been a trending reasearch for scientists for meat flavours specially.
Freeze drying
Freeze drying, also called lyophilization, is a process where material is frozen and then subjected to high vacuum pressure to sublime the frozen water in the form of vapor. It involves pretreating the product, freezing it, primary drying where ice sublimes under low pressure and heat, and secondary drying to remove remaining unfrozen water. Freeze drying retains most of the food's structure, flavor, and nutrients and produces a lightweight product with a long shelf life.
Mixing
This document discusses mixing in industrial processes. It defines mixing as manipulating a heterogeneous system to make it more homogeneous by intermingling two or more separate components. The types of mixing covered include different materials like solids, liquids, and gases. The mechanisms of mixing include shear, diffusive, and convective mixing. Common mixers are tumbling mixers, convective mixers, ribbon blenders, and others. Factors that impact mixing include mixer selection, mixing time, power consumption, and degree of mixing achieved. Agitation is also discussed and compared to mixing.
SPRAY DRYING IN MILK PROCESS
Milk is collected and tested before being stored in silos at the processing plant. It is then standardized, preheated to destroy bacteria and enzymes, and high temperature pasteurized. The milk is evaporated and concentrated to 40-50% before being homogenized and slightly heated. It is pumped at high pressure through an atomizer to create droplets that are dried in a chamber by hot air. The dried powder is separated and packaged in multi-wall bags for storage. Spray dried milk powder has applications in foods, pharmaceuticals, and various industries.

Spray dried milk powder has applications in foods, pharmaceuticals, and various industries.
Edible coating
Edible coatings can be made from polysaccharides like starch, pectin, cellulose, and alginate. They provide strength and integrity while inhibiting oxygen, aroma, and oil transfer but are not effective moisture barriers. Protein coatings also act as oxygen barriers and use proteins like soy, whey, and zein. Lipid coatings use beeswax, oils, and waxes for moisture barrier properties. Composite coatings combine materials for improved preservation of fruits and vegetables by reducing water loss, browning, and extending shelf life. Thickness must be optimized to prevent quality issues from limited gas exchange.
Blanching
Blanching is a heat treatment used prior to freezing, canning, or drying foods. It inactivates enzymes that cause quality degradation, softens texture, and improves appearance. Blanching is done using hot water, steam, or gas at temperatures between 70-100°C for 1-15 minutes depending on the food. It helps preserve color, flavor, and nutrients but some water-soluble vitamins and minerals are lost through leaching. Individual quick blanching systems improve quality by providing uniform, quick heating of individual pieces.
Lacquering keerthana
This document discusses coatings for metal food packaging cans. Lacquer coatings are applied internally and externally to cans to protect the metal and food contents. Common internal coating types include epoxy phenolic, acrylic, phenolic, and vinyl resins, which protect foods from acids and metals. External coatings provide environmental protection and allow for labeling. Proper coating selection depends on food acidity and composition to prevent corrosion and discoloration. Coatings are applied using various methods to safely contain and preserve foods.
Package Testing, Control Atmosphere Packaging, Modified Atmosphere Packaging
Package testing involves measuring characteristics and properties of packaging materials, components, and finished packages. It is important to ensure packages can protect contents during transportation and storage. Common tests include GSM, thickness, bursting strength, tear resistance, seal strength, and permeation to evaluate materials and ensure sufficient protection of contents from damage or degradation. Controlled atmosphere packaging alters gas levels around perishable foods to extend shelf life by reducing oxygen and increasing carbon dioxide to inhibit microbial growth.
Drying of food
This document provides information on various drying methods for food, including thermal drying, tray drying, flash drying, drum drying, foam mat drying, freeze drying, vacuum drying, and fluidized bed drying. It describes the basic mechanisms and processes, advantages, disadvantages, and applications of each drying technique. Key points covered include how each method removes moisture from foods using heat, reduced pressure, or other means to preserve and process agricultural products.
Shrink and strech packaging
Shrink wrapping and stretch wrapping are two common packaging methods that use plastic film. Shrink wrapping involves wrapping an item and then applying heat to shrink the film tightly around the item. The process has four stages: wrapping, sealing, shrinking with hot air, and cooling. Stretch wrapping uses elastic plastic film that is stretched to wrap around items palletized on a pallet. When stretched, the film's elastic recovery keeps the items tightly bound. Stretch wrapping provides benefits like load stabilization, efficient handling and storage, and some protection from dust, moisture, and tampering. It also saves on energy compared to shrink wrapping.
Retort pouches
Retort pouches provide a convenient packaging solution for foods. They extend shelf life without refrigeration by using a retort process involving heat and pressure to sterilize sealed food packages. Retort pouches are flexible pouches made of heat resistant multilayer plastic and sometimes aluminum foil. They allow for various food types to be packaged and have advantages over cans like being lightweight, easy to store and distribute, and providing more surface area for labels. The retort process cooks and preserves the food, making it shelf stable at room temperature for over a year. Retort pouches provide consumers with a convenient ready-to-eat package.
MAP
Modified atmosphere packaging (MAP) involves flushing air out of food packaging and replacing it with gas mixtures to extend shelf life. Common gases used are carbon dioxide to inhibit bacteria, nitrogen to displace oxygen, and low levels of oxygen for some products' appearance. Novel gases like argon and nitrous oxide may also effectively inhibit spoilage. High oxygen MAP can prevent browning but also microbial growth. Testing shows these alternative gases may effectively extend shelf life while maintaining quality for many fresh and prepared foods. MAP requires specialized equipment to control and monitor precise gas mixtures tailored to different products.
Vaccum dryer
Vacuum dryers work by reducing the chamber pressure below the vapor pressure of water through the application of vacuum, causing water to boil off rapidly without needing high heat. Vacuum dryers consist of an iron jacketed vessel containing hollow shelves and metal trays, connected to an oven and vacuum pump. Materials are dried in the trays under reduced pressure, allowing for rapid drying of heat-sensitive or hygroscopic substances through conduction without risk of degradation from high temperatures.

This is an exclusive ppt on packaging of meat products and covers all aspects of packaging from my course on "Technology of Meat, Fish and Poultry Products" (Bachelor's study)
Moisture determination and Total solid
This document discusses the importance and methods of determining moisture content in foods. It notes that moisture determination is important for quality control, processing, labeling, and microbial stability. Common methods include oven drying, where the sample is heated and weight loss determines moisture content. Factors like temperature, time, sample size and type must be controlled to avoid decomposition. Moisture can exist in different forms within foods, from bulk water to chemically bonded water. The appropriate drying method depends on the food type and desired accuracy.
Unit Operations in Food Industry
Unit operations are the fundamental physical, chemical, and biological processes used in food engineering to transform raw materials into final food products. Some key unit operations include filtration, drying, distillation, crystallization, grinding, and sedimentation. The properties of foods, such as thermal, optical, electrical, structural, mechanical, and mass transfer properties must be well understood to design effective unit operations. The main objectives of unit operations are to study the principles governing various food processing stages and the equipment used to carry them out industrially. Unit operations can be classified into physical, chemical, biochemical, momentum transfer, mass transfer, and heat transfer operations. Thermal properties of foods like specific heat, thermal conductivity, and thermal diffusivity are
Freeze concentration
Concentration of liquid foods is a vital process where water is removed while keeping the food in a liquid state. Freeze concentration is a gentle concentration method where fruit juice is frozen below its freezing point, allowing ice crystals to form and then be separated from the concentrated juice. This results in a minimum loss of quality attributes like color, flavor and nutrients compared to other concentration methods. However, some soluble solids are still lost in the separated ice crystals, resulting in a final concentrated juice of only 40-55% dry matter. Multi-stage freeze concentration can help overcome increases in viscosity during concentration.
Water activity
Water activity is the moisture content of the food which is available for microbial growth.By controlling water activity the food can be preserved for longer duration

Controlled Atmospheric Packaging- Introduction, Principle, Requirement for Id...PMG Engineering Private Limited
Oxygen is life, but in the case of foods, it is not so. When harvested, fresh fruits and vegetables
are at the peak of their quality. Their quality cannot be improved; it can only be deteriorated or
maintained. Fresh, high-quality products are the primary requirements for the national and international food industry during this current era. After harvesting, especially for fresh fruits and vegetables, continue their respiration process. The respiration rate has to be reduced to maintain quality, especially when the products are stored for an extended period or shipped to distant markets. The best way to preserve quality and extend shelf life is by cooling, and another method used to extend shelf life is the modification of the atmosphere surrounding the product. Also known as “CA storage” in the produce business, Controlled atmospheric storage is the storage in which external control systems control the atmosphere of oxygen, carbon dioxide and nitrogen (and sometimes other gases). Outside air consists of approximately 78% nitrogen (N2), 21% oxygen (O2), 0.045% carbon dioxide (CO2). CA lowers the oxygen level generally to 0.5-2.5%, depending on the type of product and the variety. CA conditions extend the shelf life of fruit and vegetables with a factor of 2 to 4.Aseptic packaging
Aseptic packaging involves sterilizing products and packaging materials under sterile conditions to prevent contamination and extend shelf life without refrigeration. It allows foods to be stored at ambient temperatures for months. The key aspects are pre-sterilizing the product using techniques like UHT and sterilizing packaging materials using methods like heat, chemicals, or radiation. Filled packages are then sealed quickly to maintain sterility. Common packaging types for aseptic storage include cartons, bags, bottles and cans. Aseptic packaging provides benefits like convenience, food safety, long shelf life and nutrient retention compared to canning.
Freezing curve, freezing system & freezing time
The document discusses freezing as an operation to preserve food by lowering its temperature below the freezing point. It describes the freezing process and freezing curve, including nucleation, crystal growth, and how solute concentration changes. It discusses factors that influence freezing time like thermal conductivity and size/shape of food pieces. Methods to calculate freezing time are presented, including Planck's equation and Pham's method. Different freezing systems are outlined like air blast freezers, plate freezers, and fluidized bed freezers.
Dough rheology
This document discusses dough rheology and various equipment used to analyze dough properties. It defines dough as a wet mass developed by mixing wheat flour, water, and other ingredients. Dough undergoes viscosity changes during mixing as it develops elastic and extensible characteristics. Equipment described includes the farinograph, extensograph, alveograph, mixograph, amylograph, and rapid visco analyzer. These tools measure properties like water absorption, viscosity, elasticity, and strength to evaluate dough development and quality.
canning of meat
Canning is a process that preserves food by heating it in hermetically sealed containers to kill microorganisms. It involves preparing and cutting meat into cubes, filling cans leaving headspace, exhausting air from cans then sealing them. The sealed cans are then thermally processed by heating to 121C for 1 hour to kill bacteria before rapidly cooling, washing, labeling, and lacquering the cans.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

https://www.etran.rs/2024/en/home-english/The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Anticaking agents and Glidants
- 1. GLIDANTS ANTICAKING AGENTS Presentation by D.A.Dasuni Prasadika Bpharm
- 2. Content ■ Introduction of glidants ■ Functions and examples of glidants ■ Definition of anticaking agents ■ Examples of anticaking agents
- 3. Introduction of glidants Glidant is a substance that is added to a powder to improve its flowability. ■ A glidant’s effect is due to a counteraction of factors resulting in poor flowability of powders. ■ For instance, correcting surface irregularity reducing interparticular friction. ■ The result is a decrease in the angle of repose which is an indication of an enhanced powder’s flowability .
- 4. Functions of glidants. ■ To improve powder flowability ■ To reduce interparticular friction ■ To reduce the cohesion Examples -: ■ Magnesium sterate ■ Aerosol , colloidal silicon dioxide ■ Starch and talc.
- 5. Definition of Anticaking agents Anticaking agent is an additive placed in powdered or granulated materials to prevent the formation of lumps, easing packaging,transport and consumption . ■ Function of anticaking agents By competing with host powder for moisture anticaking agents have strong water adsorptive ability. So that they can compete with host powdered medicine product particles for available water thus, reducing hygroscopicity consequently its tendency to cake. So the function is adsorbing excess moisture or by coating particles and making them water repellent .
- 6. Examples for anticaking agents ■ Calcium carbonate ■ Magnesium carbonate ■ Sodium aminosilicate ■ Sodium ferrocyanide ■ Potassium ferrocyanide
