Cooling and Reheating of Potentially Hazardous Foods The cooling requirement limits the length of time that potentially hazardous food is in the temperature range at which harmful bacteria can grow. Foods particularly important to meet the cooling requirement include soups, sauces, gravies, stews, rice, chili, whole turkeys, turkey breasts and whole roast beef. Food temperatures should be measured with a stem thermometer. There are several ways to rapidly cool potentially hazardous food. The manager of the establishment should determine which method or combination of methods is most effective for a particular food. The methods of cooling are: Stir soups, sauces, gravies and chilies while the container is in an ice water bath.

Food Preservation Methods: Canning, Freezing, and Drying About canning food. Canning is the process of applying heat to food that’s sealed in a jar in order to destroy any microorganisms that can cause food spoilage. Proper canning techniques stop this spoilage by heating the food for a specific period of time and killing these unwanted microorganisms.

In the Can: A Look at Retorting The second phenomenon to consider is the heat transfer process. In retort containers, after the heat passes through the container via conduction, it can heat the food in two ways. Conduction is appropriate for solid pack foods such as pumpkin and dog food, or for foods with solid particulates.

"What is the definition of ""processed food""?" any food other than a raw agricultural commodity and includes any raw agricultural commodity that has been subject to processing, such as canning, cooking, freezing, dehydration, or milling. Examples of processing include: The examples of processing in the definition are sparse, but it is clear.ven the life food movement uses dehydration, freezing, and milling, and most adherents would claim that they don't eat processed foods. Interesting that the definition doesn't include things like fermentation or curing/pickling-unless those are included in the legal definition of cooking, which they may be.

Food preservation Food preservation refers to any one of a number of techniques used to prevent food from spoiling.All foods begin to spoil as soon as they are harvested or slaughtered. Some spoiling is caused by such microorganisms as bacteria and mold.ges-old food preservation techniques include drying, smoking, cooling, freezing, fermenting, salting, pickling, and canning. Drying and smoking. One of the most ancient methods of food preservation is sun-or air-drying. Drying works because it removes much of the food's water.

Rapid thermal processing Rapid thermal processing. Rapid Thermal Processing (RTP) refers to a semiconductor manufacturing process which heats silicon wafers to high temperatures (over 1,000 °C) on a timescale of several seconds or less. During cooling, however, wafer temperatures must be brought down slowly to prevent dislocations and wafer breakage due to thermal shock.

Browning The term “ browning ” in relation to food refers to several different processes which can be divided into enzymatic and non-enzymatic browning reactions. The most common type of non-enzymatic browning is the Maillard reaction. It refers to a series of chemical reactions between sugars and proteins that make foods more appetizing. Examples are the flavours and colours produced during baking bread or frying meat. The second type of non-enzymatic browning is carmelization that occurs when carbohydrates/sugars in any food are heated.

Food Science: What's the Deal with Ultra-Pasteurization? In the ultra-pasteurization process, milk or cream is sent through pipes where it's heated almost instantaneously to around 280° and then cooled again almost as quickly. This is as compared to the regular pasteurization process which heats milk to a minimum of 162° for fifteen seconds. On the one hand, ultra-pasteurization means that enormous quantities of milk can be processed much more quickly than any other pasteurization (or safety regulation) process. The milk is also shelf-stable for several months. On the other hand, the treatment changes the taste and texture of the dairy.

The greatest thing since sliced bread? A review of the benefits of processed foods Food processing can lead to improvements in, or damage to, the nutritional value of foods. Simple food preparation processes in the domestic kitchen lead to inevitable damage to the cells of plant foods, leading to leaching of essential vitamins and minerals.he salt may be added as such or be rubbed into meat. Salt fish (dried and salted cod) and salt-cured meat such as Italian prosciutto crudo are examples of salted foods. Other food processing methods in which salt plays a role are brining and pickling.
