edible oils and their quality aspects
India produces around 25 million tons of edible oils per year from various oilseed crops like groundnuts, soybeans, rapeseed/mustard, sesame, and niger. The major edible oils produced are groundnut, soybean, rapeseed/mustard, sesame, and sunflower oils. Various quality aspects of edible oils are regulated by acts and standards organizations to ensure safety and nutritional quality. Oils undergo various tests to check parameters like acid value, iodine value, fatty acid profile and contaminants to ensure they meet standards before packaging and labeling for consumers.
Fats and oils
This document summarizes key information about fats and oils, including their structure, rancidity, and how heat affects them. It also outlines several extraction methods for fats and oils like rendering, pressing, and solvent extraction. Refining processes are discussed along with winterization and hydrogenation. Shortenings and their uses in foods are covered. Finally, the document defines cholesterol, lists foods containing it, and outlines its functions in the body.
Processing of oil and fat
Processing edible oils and fats involves refining them through several steps:
1) Lecithin removal uses water to separate phospholipids from crude oil.
2) Degumming coagulates proteins and carbohydrates with phosphoric acid before filtering.
3) Free fatty acid removal uses sodium hydroxide to remove fatty acids, which are washed out with hot water.
4) Bleaching uses aluminum silicates to remove plant pigments like chlorophyll through vacuum filtration.
5) Deodorization is vacuum steam distillation to separate volatile compounds and odors over 20 minutes to 6 hours.
Chemical refining of crude palm oil
The three step chemical refining process of crude palm oil removes different compounds at each stage. In degumming, phosphatide gums are removed. Alkali neutralization removes soapstock and splits free fatty acids from soapstock. Bleaching and filtration then removes residual color using bleaching agents. Finally, deodorization removes odor compounds and peroxides to produce a bland, refined palm oil.
Deodorization- Important Unit operation in Oil Processing
This document provides an overview of the deodorization process, which is the final stage in edible oil refining. It aims to remove odor-causing compounds and other undesirable elements. The key points covered include:
- Deodorization uses high temperature, high vacuum distillation to strip volatile components like free fatty acids and contaminants.
- Process variables like temperature, pressure, time and steam usage influence the removal of odors and quality of the final oil.
- Common odor sources in oils include oxidation products and thermal degradation compounds.
- The underlying principles of deodorization relate to the differing volatilities of oil constituents and steam stripping them away.
- Typical process steps are
Soaps and syndetbars sushil kumar singh
This document summarizes soaps and syndet bars. It discusses the history of soaps and the raw materials used, including fats/oils and alkalis. The manufacturing processes for cold, semi-boiled and full-boiled soap are described. Different types of soaps like transparent, bathing, Castile and carbolic soaps are shown through pictures. Syndet bars are introduced as synthetic detergent bars made of surfactants derived from oils through chemical processes instead of saponification. The key differences between soaps and syndet bars are that soaps have a higher pH and can be harsh on skin while syndet bars have a more neutral pH similar to skin.
Activated Carbon
Activated carbon is a form of carbon processed to be riddled with small, low-volume pores that increase the surface area available for adsorption or chemical reactions.
Production of Glycerin (Unit 4 b)
The document discusses the production of glycerine from soap plants and fatty acid production. Glycerine is produced as a byproduct from saponification of fats and oils with caustic soda in soap production. It is extracted from spent lye and purified through chemical treatment, evaporation, salt separation, and refining including distillation. Glycerine is also recovered from fatty acid production where triglycerides are hydrolyzed into glycerol and fatty acids. The crude glycerine obtained is purified through neutralization, evaporation, filtration and vacuum distillation.

A potassium deficiency can cause muscle cramps, congestive heart failure, diarrhea, and other conditions. It is important to get adequate potassium through diet or supplements.
Potassium Cycle
Potassium is essential for many plant and biological functions. It makes up 2.6% of the Earth's crust and 0.2% of the human body. Potassium was first isolated in 1807 and comes from minerals like feldspar and mica in the soil. Plants accumulate potassium, making fresh fruits and vegetables a good dietary source. Potassium is lost from soil through erosion, runoff, leaching, and harvesting of plants, so fertilizers are needed to replenish potassium in agricultural production.

Pictures and images are a great way to tell visual stories and share experiences. The internet provides many options for hosting and sharing pictures online through free websites and platforms. Popular picture websites make it easy to upload photos, organize albums, and grant access and permissions to share images with others.
Potassium
1) The document discusses evolving concepts in potassium homeostasis and hypokalemia. It highlights recent insights showing that feedforward control mechanisms sense decreases in potassium intake and activate conservation responses even before plasma potassium levels fall or hypokalemia occurs. 2) Feedback control mechanisms, such as increased aldosterone secretion in response to rising potassium levels, help regulate potassium excretion and balance. 3) Both feedback and feedforward controls are important in maintaining potassium homeostasis and preventing hypokalemia. The interplay between these controls is more complex than previously understood.
POTASSIUM IN PLANT GROWTH AND YIELD
Potassium plays a critical role in many processes important for plant growth and yield. It is essential for cell elongation, maintaining turgor pressure, photosynthesis, protein synthesis, phloem transport of photosynthates, and stomatal regulation of gas exchange. Potassium transporter proteins are important for potassium uptake and translocation within the plant. Adequate potassium nutrition helps plants tolerate environmental stresses like drought, high light intensity, and salinity. Plants exposed to these stresses have higher potassium requirements. Maintaining sufficient potassium levels is important for maximizing plant protection against stresses under marginal growth conditions.

Sir Humphrey Davy discovered potassium in 1807 in England. The name potassium comes from "potash" and the Arabic word "qali" meaning alkali. Potassium maintains intracellular osmotic pressure and is important for nerve impulse transmission, protein biosynthesis, and cardiac activity. Dietary requirements are 3-4 grams per day, and potassium-rich foods include tender coconut water. Potassium is well-absorbed from the gastrointestinal tract and excreted mainly through urine.Viewers also liked (7)

ALKADIENES
Alkadienes are hydrocarbons that contain two carbon-carbon double bonds. They can be classified based on the location and relationship of the double bonds as cumulated, conjugated, or isolated. Cumulated dienes are reactive, while conjugated dienes have similar physical and chemical properties to alkenes. Isolated dienes behave similarly to monoolefins. Alkadienes are used in the production of tires and plastics. Exposure safety hazards include possible cancer risks from inhalation or skin contact. Symptoms from inhalation include respiratory irritation and effects on the central nervous system. Skin or eye contact may cause burns or irritation.
FLOATATION REAGENTS
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters by removing suspended matter such as oil or solids. This is achieved by dissolving air into the water under pressure and releasing it, causing air bubbles to adhere to suspended particles and causing them to float. DAF is widely used to treat industrial wastewater from facilities like oil refineries, chemical plants, and paper mills. A similar process called induced gas flotation is also used for wastewater treatment. In the mineral processing industry, froth flotation is commonly used to separate minerals.
GALLIUM
Gallium was first predicted in 1871 and discovered in 1875. It is extracted as a byproduct of aluminum and zinc production from bauxite and sphalerite ores. Gallium does not exist freely in nature. It has a low melting point slightly above room temperature and is used in integrated circuits, LEDs, solar panels, medical thermometers, and mirrors due to its semiconductor and alloying properties.
TROMMEL SCREEN
Trommel screens consist of a drum, frame, hopper, reducer, and motor. Broken stone is fed into the rotating drum where larger materials move forward and are separated by screens of different mesh sizes into different hoppers. The separated materials are then sent to individual product stacks by conveyor or manually depending on size specifications, with anything larger than the last screen mesh discharged from the outlet. Trommel screens operate slowly and steadily for simple classification of materials like refractories, coal, sand and mixtures in a process requiring minimal specialized installation.
JAW CRUSHER
Jaw crushers are primarily used for coarse and medium crushing of materials in mining, construction, and other industries. They use compressive force from two jaws, one stationary and one that reciprocates, to crush particles in the crushing chamber. Jaw crushers come in different sizes depending on the width of their feeding mechanism and can be used for simple crushing needs with reliable operation and easy maintenance.
GRAVITY THICKENER
Gravity thickeners use sedimentation to concentrate sludge through the settling of solids. Flocculant is added to the feedwell to cause fine particles to bind together and settle rapidly. Rake arms slowly rotate to push settled solids towards the deflector cone, from which concentrated underflow is pumped out. Clear overflow is discharged from the top of the thickener.
AIR CLASSIFIER
Air classification is a process that uses a double cone air classifier to modify the particle size distribution of dry powders according to end user requirements. The air classifier centrifugally separates coarse and fine particles by conveying material through rotating blades that create an airflow, with coarser particles accumulating in the central cone and finer particles transported out of the separator by the air. Air classifiers have a wide range of applications in industries that handle powders like paints, dyes, pharmaceuticals, and more.
Gravity thickener
Gravity thickeners use sedimentation to concentrate biosolids and produce a thickened sludge and relatively clear liquid. Solids separate from the liquid stream through gravity settling in large tanks. Common components include tanks, a drive system, rakes, and feedwells. Rakes slowly rotate to move settled solids towards a central deflector cone for removal as thickened underflow, while clarified liquid overflows the top of the tank. Flocculants are added to promote particle bonding and rapid settling.

The entrainer allows either the separation of a closely boiling pair or the separation of an azeotrope into its components. A diagram shows the process of mixing the feed and entrainer before distillation in two columns to separately remove the key components and recycle the entrainer.
ROTARY DRYER
The rotary dryer is a type of industrial dryer that reduces the moisture content of materials by bringing them into direct contact with heated gas. It consists of a cylindrical shell that rotates, allowing material to be fed in at one end and discharged at the lower end as it dries. As the dryer rotates, internal fins lift the material through a hot gas stream to evaporate moisture before it falls back to the bottom. Rotary dryers can dry a wide range of materials effectively and are commonly used in mineral processing to dry products like sands, limestone, ores, and coal.
WET COOLING TOWER
This document describes the process of how wet cooling towers function to transfer waste heat from industrial processes to the atmosphere. The warm water returns to the top of the cooling tower and trickles down over fill material, contacting an upward flow of ambient air induced by fans. This contact causes some of the water to evaporate, cooling the remaining water which is then ready to recirculate. Dissolved salts are left behind in the water, increasing its concentration, so blowdown removes some water to control the salt level while fresh makeup water is added to compensate for losses from evaporation, drift, and blowdown.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
