The document discusses the principles of food processing and preservation. It covers four key points:
1) Food preservation aims to extend shelf life by inhibiting microbial growth and chemical deterioration through methods like controlling temperature, moisture, pH and atmosphere.
2) Common preservation methods include freezing, drying, pickling, canning and salting which inactivate microbes using techniques like heat, cold or high salt levels.
3) Spoilage is caused by enzymes, microbes and chemical/physical factors like oxygen and light. Proper handling and storage conditions are important to prevent damage.
4) Preservatives like sulfites, nitrites and benzoic acid are used as antimicrobials to inhibit bacteria, yeast
Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. Chemistry informs us about changes in food during processing and storage, and explains changes during cooking like how ingredients interact and how our body uses food. Chemical substances can play an important role in food production, preservation and quality control through prolonging shelf life, making food more attractive, and fighting diseases in crops and livestock.
This document discusses bleaching and maturing agents used in food processing and preservation. It defines bleaching agents as substances that alter the color of foods by lightening them, while maturing agents aid in the natural aging of foods to enhance flavor and texture over time. Common bleaching agents are hydrogen peroxide and chlorine dioxide, while ascorbic acid and chlorine dioxide are examples of maturing agents. The document also outlines the effects of bleaching and maturing agents on foods as well as their applications in industries like baking, meat processing, and dairy production.
Cooking involves applying heat to food, which alters its molecular structure, texture, flavor, aroma, and appearance. Heat destroys microorganisms and makes food easier to digest. The main components of food - carbohydrates, fats, proteins, water, and minerals - react differently to heat. Carbohydrates like starches gelatinize and thicken sauces when heated in water, while sugars caramelize and brown. Proteins coagulate at high temperatures, and fats melt and can smoke if heated above their smoke point. Understanding how heat affects these components is key to basic cooking principles.

This document discusses microbial food spoilage. It defines food spoilage as when a food loses its acceptance qualities due to factors like changes in color, odor, flavor, texture or microbial growth. The main causes of spoilage are physical, chemical and microbial processes. Microbial spoilage specifically is caused by the growth and metabolic activities of microorganisms like bacteria, molds, yeasts and viruses. The document outlines the various intrinsic and extrinsic factors that influence microbial growth in foods and provides examples of different microorganisms that commonly cause spoilage of various food types.
Microbial factors responsible for the spoilage of food Sunidhi Shreya
Microbial factors are responsible for food spoilage through biochemical changes. Key microbial spoilage processes include fermentation, where microbes derive energy from organic compounds; rancidity, the decomposition of fats and oils; and putrefaction, the breakdown of proteins by anaerobic microbes. Specific biochemical changes include the decomposition of proteins, carbohydrates, lipids, and pectin in fruits and vegetables. The microbial community in foods changes over time in a process known as succession, as different microbes dominate at different stages of spoilage depending on the chemical environment. For example, in spoiled raw milk the succession proceeds from lactic acid bacteria to yeasts and molds and finally to protein-digesting bacteria.
This document provides an overview of important topics in food technology, including food additives, colors, fruits and vegetables, specifications, flavors, beverages, crops, and relevant acts. It defines food additives and lists common types including antioxidants, preservatives, chlorine compounds, fumigants, sequestrants, surface active agents, coloring agents, stabilizers, sweetening agents, and bleaching agents. It also discusses specifications for various fruit products, important flavors, famous crops and their production areas in India, and acts governing the food industry.
This document discusses food additives, including their definition, functions, categories, effects, banned additives, and regulation under food safety laws. Food additives are substances added to food to maintain or improve safety, freshness, taste, texture or appearance. They help preserve nutrients, control acidity and flavor, and color food. Common categories include preservatives, flavors, emulsifiers, and sweeteners. While additives can extend shelf life, some are linked to allergies, toxicity and illness. All food additives in India must be approved by the Food Safety and Standards Authority of India to ensure food is safe.
This document summarizes the key chemical components of food:
- Food is made up of chemicals organized into cellular structures. The six main categories are carbohydrates, fats, proteins, vitamins, minerals, and water.
- Carbohydrates include sugars (simple) and polysaccharides (complex) such as starch. Fats are characterized by their greasy feel. Proteins are made of amino acids and include albumins, globulins, and enzymes.
- Vitamins and minerals, though only needed in small amounts, are essential for health. Water is the most abundant element and acts as a solvent.
minimal processing of foods by non thermal methodsyeshuvarma
Minimal processing results in the least chemical change to foods, providing the highest quality but very short shelf life. More processing like drying and canning extends shelf life but results in greater chemical changes and loss of quality. Food processing aims to make foods safe, of high quality, and convenient while preventing deterioration through techniques like heat, cold, dehydration, and chemicals that act as barriers against spoilage.
Fermentation is an anaerobic process by which microorganisms like yeast and bacteria convert sugars into acids, gases or alcohols. It has been used for centuries in producing various fermented foods and beverages by utilizing the metabolic activities of microorganisms. Louis Pasteur made significant contributions to fermentation theory by demonstrating that it is caused by living microorganisms rather than decomposition. Factors like temperature, pH, oxygen levels, time and nutrients must be controlled during fermentation to achieve the desired outcomes. Fermentation improves food quality by enhancing flavor, texture, shelf life and nutrition while potentially causing negative effects like histamine intolerance in some individuals.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

freezing offers exceptional food safety and extended storage time,
many reactions such as moisture migration, lipid oxidation, and
protein denaturation promote off-flavor formation. Therefore,
stability can be achieved with a more integrated understanding of
the flavor interactions within the complexity of foods. Also,
attention should be focused on the quality of raw materials and the
overall product technology to reduce oxidation and flavor loss.
