What are some examples of improvements in nutritional value due to heat?
For example, improvements in nutritional value due to heat include gelatinisation of starches and coagulation of proteins, which improve their digestibility, and destruction of antinutritional compounds (e.g. a trypsin inhibitor in legumes).
What is thermal food processing?
Thermal food processing is a cost-efficient treatment widely used by industries to achieve food safety and extended shelf life. The health value and the economic contributions of food processing are imperatives of a sustainable food supply and must include attention to minimizing food-borne illness and food waste, retaining or enhancing nutritive quality, and increasing food availability, security, and affordability. While many of the aforementioned imperatives are achieved with thermal processing, there is concern that nutritive quality may be compromised, including deleterious effects on traditional essential nutrients and nontraditional bioactive phytochemicals. The present article highlighted some of the research quantifying changes of bioactive phytochemicals with thermal processing. Several inconsistencies in outcomes and variables in processing make it difficult to make conclusions. Further, there are few studies examining the importance of chemical changes in response to processing relative to the bioaccessibility, bioavailability, and biological effects of phytochemicals after different processing conditions. Ultimately, the goal is to process food to promote optimal health. Hence, the area is relatively young in its development and is an important area for continued research attention to understand the effects of processing on the nutritive and health-promoting quality of foods, including the relevance of these effects in humans.
What are the sources of PAHs in food?
Heat-processing procedures during food preparation, in particular grilling, roasting, and smoking, involving direct contact with combustion gases, are among the major sources of PAH contamination in food. The level of contamination in smoked products is related to the time and temperature of processing, humidity, types of control and smoke used, and the design and types of kilns. Modern kilns have strict electronic control of the entire process. Different types of wood or woodchips used to generate smoke produce different amounts of PAHs, with the highest concentration found when spruce, hazel tree, plum tree, and aspen are used, whereas they are lowest when apple tree, alder, and maple are burned. Over the last decades, commercial smoked food production has generally replaced the traditional smoking process with the use of liquid smoke flavoring. The latter derives from smoke subjected to fractionation and purification; thus, the content of PAHs on the final product is greatly reduced and strictly controlled.
What is the process of heat processing meat?
Heat processing of meat is responsible for the generation of nonenzymatic browning or Maillard reaction in which reducing sugars or aldehyde groups from other sources , including lipid oxidation, react with the amino groups from amino acids, peptides, and proteins. The resultant compounds are responsible for the generation of desirable aroma and color in meat and other heat-processed products. Many final products of the Maillard reaction are heterocyclic in nature with desirable sensory characteristics. Strecker degradation also leads to the formation of products that participate in the generation of other compounds. Phospholipids play a role in this respect as well.
What is the most dramatic procedure carried out during the manufacture of canned products?
Heat processing or sterilization is the most dramatic procedure carried out during the manufacture of canned products and by definition guarantees the sterility of the final product ( Aubourg, 2001 ). To maintain the quality of, for example, canned fish, three conditions must be maintained.
Why are vitamin losses included in subsequent chapters?
Reported vitamin losses during processing are included in subsequent chapters to give an indication of the severity of each unit operation. However, such data should be treated with caution. Variation in nutrient losses between cultivars or varieties can exceed differences caused by particular methods of processing.
How does heat processing affect vegetable texture?
Heat processing in water or brine leads to hydration of starch and cell wall polysaccharides and results in a soft textured vegetable that easily forms a paste during mastication. If the heat process could be reduced significantly or eliminated, a texture more resembling the raw material could feasibly be achieved. Non-thermal processing techniques, such as those based on high- intensity electric field pulses or high-pressure treatments, are therefore receiving considerable attention. Studies on low heat input processes are likely to continue in the future. Further developments are likely in modified atmosphere storage of raw vegetables that could have significant effects on the texture of the processed products. In particular, the use of ethylene inhibitors is expected to have a considerable impact on current techniques for controlling rate of ripening/maturation and, if applied to vegetables for processing, could have a beneficial impact on final product texture.
What is heat treatment?
Heat treatment of products is one of the main techniques in the food industry for food conservation. Heat treatment stops bacterial and enzyme activity; thus preventing a loss of quality and keeping food non-perishable.
What is sterilization in food?
Sterilisation is the removal of living micro-organisms, and can be achieved by moist heat, dry heat, filtration, irradiation, or by chemical methods. Compared to pasteurisation, a heat treatment of over 100°C is applied for a period long enough to lead to a stable product shelf-life.
How long to sterilize food in autoclave?
In sterilisation with moist heat, temperatures generally range from 110 to 120°C with sterilisation times being from 20 - 40 minutes. For example, canned foods are sterilised in an autoclave at about 121˚C for 20 min. Higher temperatures and shorter times may have similar effects (e.g., 134˚C for 3 min.). However, if conditions do not allow the germination of spores, lower temperatures and shorter times can also be applied. For example, with acid fruit juices, jam, or desserts, heating to 80 – 100˚C for 10 min is normally sufficient.#N#For killing bacterial endospores by dry heat, longer exposure times (e.g. up to 2 hours) and higher temperatures (e.g. 160 – 180˚C) are required than with moist heat.#N#Solutions containing thermolabile compounds can be sterilised by filtration through mediums such as nitrocellulose membranes, kieselguhr, porcelain, asbestos. UV irradiation is used to keep rooms partially sterile. Bacteria and their spores are killed quickly, but fungal spores are only moderately sensitive to radiation. Ionising radiation (X ray, gamma radiation) is used to sterilise food and other compact materials. Chemical means may also be applied. Ethylene oxide is used to sterilize food, plastics, glassware, and other equipment. [87, Ullmann, 2001]#N#Generally for sterilisation, the product is canned or bottled and then heat-treated in a steriliser with steam or hot (superheated) water. Sterilisers may be batch or continuous by operated.
What temperature should I use for pasteurization?

Is UHT sterilized before transfer?
This results in a sterilised product with minimal heat damage to the product properties. UHT treatment is only possible in flow-through equipment. The product is thus sterilised before it is transferred to pre-sterilised containers in a sterile atmosphere. This requires aseptic processing.
What is thermally processed?
Thermally processed, commercially sterile finished products are products in cans or flexible containers such as pouches, or semi-rigid, as in lunch bowls. Thermally processed, commercially sterile products are addressed in 9 CFR 431.
What is a FSIS process?
This process category applies to establishments that further process by using a heat treatment processing step to achieve food safety in combination with curing, drying , or fermenting processing step to achieve food safety. The finished products produced under this process category are shelf stable. FSIS does not require shelf stable products to be frozen or refrigerated for food safety purposes. If the establishment produces using the processing steps applicable under this process category and the product is not shelf stable, then establishment is producing product under the process category Fully Cooked -Not Shelf Stable.
What is a process category?
This process category applies to establishments that further process by curing, drying, or fermenting processing step as the sole means by which product achieves food safety. Establishments in this process category may apply a low-level heat treatment as long as the heat treatment is not used as means to achieve food safety. The finished products produced under this Process Categories are shelf stable. FSIS does not require shelf stable products to be frozen or refrigerated for food safety purposes.
When was heat used in food preservation?
The application of heat as a preservation method dates back to the nineteenth century, with the ‘appertization’ process developed by Nicolas Appert, oriented to intentionally establish a new method for preserving food. It marked the beginning of a huge industry based on the use of heat to preserve food.
Why are high acid foods not heat resistant?
That is because they are high-acid foods (pH < 4.5) which cannot support the growth of heat-resistant spore forming pathogens. High-acid foods are subject to spoilage principally by yeasts and molds, which have low heat resistance and can be inactivated by pasteurization heat treatments, alone.
How efficient are plate heat exchangers?
Plate heat exchangers are exceptionally efficient in processing fluid products (see Table 12.2 for a summary of advantages of aseptic food sterilisation systems). Product-to-product regeneration is possible; as much as 90% of the heating and cooling requirement can be done through regeneration.
How does electrostatic sterilization work?
Developed countries have already grasped the importance of electrostatic technology in food sterilization. The mechanism uses an ion atmosphere or ozone, which is generated by an electrostatic field to sterilize foods. This technique can achieve excellent sterilization and preservation effects. Ozone can kill bacteria and molds in grain, fruits, bottles, tanks, and bags, as well those in the storage room. The sterilization speed is approximately 15–30 times faster than oxygen. Furthermore, when the components of food were subjected to electrostatic sterilization, no changes were observed in food when it was compared to food without sterilization treatment. Thus, this technique protects the original flavors of food.
What is the main concern of the canning industry?
In acidified and low-acid canned-food sterilisation, the main concern of the canning industry is to prevent the growth of Clostridium botulinum, the food-poisoning bacterium capable of producing a highly lethal toxin. C. botulinum is a heat-resistant bacterium.
What is high pressure food processing?
High pressure processing is a relatively new non-thermal food processing method that subjects liquid or solid foods, with or without packaging, to pressures between 50 and 1000 MPa. Extensive investigations have revealed the potential benefits of high pressure processing as an alternative to traditional heat treatments. These benefits are apparent in various areas of food processing, such as the inactivation of microorganisms and enzymes, denaturation and alteration of the functionality of proteins, and structural changes to food materials. Moreover, high pressure can be used to enhance several processing operations, such as freezing, thawing and extraction, thus providing new processing options.
How fast does ozone sterilize?
Ozone can kill bacteria and molds in grain, fruits, bottles, tanks, and bags, as well those in the storage room. The sterilization speed is approximately 15–30 times faster than oxygen.
Why is heat treatment important?
Heat treatment plays an essential role in securing product quality and shelf life. It has long been thought that much of the vitamin C content in orange juice is destroyed during the pasteurization process. In principle, vitamin C degradation occurs faster as temperature increases, as with many chemical reactions.
Why do fruit drinks not need UHT?
This is because their high acidity inhibits the growth of bacteria, fungi and yeast. Their heat treatment should be safe, but still be able to deliver quality in terms of vitamins, colour and taste.
How often is orange juice pasteurized?
Orange juice is normally pasteurized at least twice before it reaches the consumer. It is pasteurized immediately after extraction, before bulk storage, then again before packaging. Some NFC (not from concentrate) juice is pasteurized only once.
Why is it important to pasteurize fruit juice?
Pasteurization kills microorganisms that can grow during storage and inactivates enzymes that cause unwanted clarification (cloud loss).
Does pasteurizing juice affect vitamin C?
One might therefore conclude that pasteurization would result in large vitamin C losses. However, the latest research shows that during standard juice pasteurization (80-105°C for 15-30 seconds) the time the juice spends at an elevated temperature is very short, and the impact on vitamin C is negligible.
What is decontamination in healthcare?
decontamination. reduces number of pathogens to a safe level. Healthcare-associated infection (HAI) infections acquired while receiving treatment in a hospital or other healthcare facility. disinfection by-products (DBPs) compounds formed when chlorine or other disinfectants react with natural chemicals in water.
Which is more efficient, a membrane or a depth filter?
a) Depth filters have much smaller pores than membrane filters, and are therefore far more efficient than membrane filters. b) Membrane filters have smaller pores than depth filters, but depth filters have complex passages that retain microbes while letting the fluid through. Both methods are efficient.
