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.
A retort pouch or retortable pouch is a type of food packaging made from a laminate of flexible plastic and metal foils. It allows the sterile packaging of a wide variety of food and drink handled by aseptic processing, and is used as an alternative to traditional industrial canning methods

Packaging materials: Paper based packaging for foodDr. Jilen Mayani
Paper is a very versatile material. It is produced from cellulosic, naturally renewable fibres. It is therefore considered as an environmentally friendly material, being easily recycled, composted or incinerated after use. It may be used in food packaging applications within a wide range of grammages, being designed as wrapping paper, folding box board or corrugated board, for direct or indirect contact, i.e. as primary, secondary or tertiary packaging. Other paper grades, such as tissue paper, may be used in occasional contact with foodstuffs.
When paper and paper based products are intended, or likely, to come into contact with food, manufacturers follow relevant and acknowledged regulations and guidelines to design manufacturing processes and recipes, and ensure consumer safety.

Shrink packaging
Shrink packaging indicates the process in which sheets of transparent plastic film are wrapped around a product to form a solid, weather-resistant packaging layer.
Shrink packaging customarily refers to plastic films which have been pre-heated, stretched and cooled prior to use. This causes their initially randomly scattered molecules to align themselves in rigid structures, creating flat sheets of plastic film.
Shrink-wrap
When the shrink packaging films are applied to the product and re-heated, the molecules revert to their previous non-aligned state. This causes the plastic film to shrink and wrap itself tightly around the form and shape of the product (therefore the name ‘shrink-wrap’).
Stretch-wrap
When shrink packaging is simply stretched and wrapped around the product without being re-heated, it is known as ‘stretch-wrap’.
Benefits of shrink-packaging
Shrink packaging offers a versatile, cost-effective packaging solution for several reasons.
First, the materials used (plastic derivatives) are strong yet flexible, and provide effective protection, as well as making the product tamper-proof.
Second, shrink packaging is transparent, making it suitable for retail and wholesale display, and ideal for general marketing purposes due to its clear surface.
Third, shrink packaging is a relatively inexpensive option and ideal for low-cost packaging solutions.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
2. Introduction
• The processing industry is always looking for
ways to extend shelf-life and preserve foods
as well as diversify the ways in which these
goals are accomplished.
• Consumers like to see new products and will
buy things if they are more convenient.
• The retort pouch is the perfect answer for the
consumer and the producer.
2
3. What is Retort?
• DEFINITION:
• A retort pouch as “a flexible
package in which prepared food is
hermetically sealed for long-term
unrefrigerated storage.”
(1977,Webster)
• Retort is a process that uses heat
and pressure to cook food in a
strong, sealed package.
• It is the most acceptable form of
food preservation in rigid, semi
rigid and flexible packaging
system. 3
4. History
• The U.S. Army promoted the concept of
flexible retort able pouches for use in
combat rations, or MRE’s (meals ready to
eat) in the 1950's
• Concept:
• Retort pouch is a flexible package made
from multilayer plastic films with or
without aluminium foil as one of the layers.
• Their most important feature is that, unlike
usual flexible pouches they are made of
heat resistant plastics, thus making them
suitable for processing in retorts at
temperature of around 121°C normally
encountered in thermal sterilization of
food.

• TO DESTROY
MICROORGANISMS BY
HEATING
• THERMAL PROCESSING OF
FOODWITH PACKAGE ITSELF
• TO PROTECTTHE FOOD FORM
CHEMICAL ENZYMES
• TO PROVIDETHE FOOD
COMERCIALLY STERILE
• TO COOK FOOD READY FOR

6. Structure of retort pouch
• These flexible pouches are
constructed with 4 ply laminate
consisting of following:
• Polyester outside layer (High
Temperature Resistance,
Toughness and Printability)
• Nylon 2nd Layer (Abrasion
Resistance)
• Aluminium Foil (Barrier to Light,
Gases, Micro organisms, Odours.
Extends Shelf life, Stiffness allows
for theTear notch)
• Polypropylene Inside Food contact
layer (Good heat seal surface,
Flexibility, Strength and Food
Capability)
6
7. Why retort pouch is better than
other forms?:
• The easy to open “notch” has eliminated the need to
use can openers and reduces the risk of cuts after
opening.
• Labels can be printed into the laminate, making them
permanent.
• Flexible pouches are easier to distribute and therefore
have lower transportation costs and require less
disposal space.
• Storage space for empty flexible pouches is also
reduced. A 45 ft. trailer holds 200,000 8 oz cans or 2.3
million retort pouches.
• Regular waste disposal no special recycling bins
required
7
8. Characteristics essential to a satisfactory retort
pouch are:
• Low gas permeability (oxygen).
• Low moisture permeability.
• Low hydrophilic properties.
• Heat sealable and sterilisable.
• Resistant to penetration by fats, oils and other food components.
• Physical strength to resist physical abuse during packing.
• Absence of solvent residues. Chemically inert polypropylene films
require manufacturing catalysts, which must be removed with
solvents before the film can be used for foods.
• Bonding materials for the laminates must not migrate into the
foods.
• High light barrier.
8
9. TYPES OF RETORT POUCHES
• Preformed pouch
• In line formed Pouches
• Pillow Pack :-
3-side sealed
4-side sealed
• Stand up pouch
9
10. Processing of Food in Retort Pouches :
• Printing:
• The first step in the manufacture of laminate for pouches
involves printing the polyester film.
• Filling:
• Filling the pouches with raw material is the first step in the
process.
• Air Removal
• Removal of air from the filled pouch is done to remove the
bulk of the air from retort pouches before they are sealed
• Sealing:-
• by impulse sealing. 10
11. • Traying:
• After the pouches are sealed, it is transferred to a retort
rack or tray on which each pouch is accommodated in a
separate compartment or slot.
• Processing:-
• The pouches are then heat processed in an over pressure
autoclave.
11
12. Advantages of Retort Pouch
From Consumers Point ofView :-
•Easy to handle
•Easy to cook
•Easy to open
•The thin profile permits reduced heating time & less chance of
overcook.
•Self-stable and requires no refrigeration
•Reduced storage space
•Larger surface area for marketing information
•Lighter and less expensive to ship
•Easier for customer to open, heat and use product
•Flexible pouches are easier to distribute and less logistic costs.
12
13. Limitations of retort pouch:
• The first obstacle is that processors often require a large
capital investment for the unique machinery. Filling is
slower and more complex compared to metal can lines.
• The thermal process is complex due to the number of critical
processing parameters which must be monitored (e.g.,
residual air, pouch thickness, steam/air mixture). Also,
special racking systems may need to be set up in order to
provide optimal heating media flow and prevent pouch to
pouch contact.
• Since pouches are more easily punctured they may require
over-wrapping for distribution.
• Specialized equipment such as a burst tester, or a tensile
tester is required for leak detection and container 13
14. LATEST TECHNOLOGIES
• Self-contained, self-heating ready-to-eat food packet is the one that have
been developed recently.The unique aspect of this packet is that it has three
compartments - one to house the food and the other two to hold a special
liquid and a chemical powder, respectively. All that a retail customer has to
do is to connect the liquid and the chemical power compartments; this will
not spoil the hands.The heat generated due to chemical reaction will be
transferred to the compartment that holds the food and make it ready to
eat in few minutes. According to calculations each packet would cost around
Rs 15-20 and companies can target picnic-goers and travelers.
