Processing milk through UHT treatment does take up energy and hard to economize. Aseptic Filling. Introduction and Historical. Pages Milk to milk regeneration was used with both processes.
Microbiological, chemical, physical, and proteolytic activities of raw milk after thermal processing. Milaneze 1. Kottwitz 2. Fonseca 3. The aim was to evaluate the microbiological, chemical- physical, and shelf-life quality of milk samples after pasteurization HTST for 10 days or ultra-high temperature UHT treatment for days.
It seems that you're in Germany. We have a dedicated site for Germany. This book attempts to explain the scientific basis for UHT sterilization and aseptic filling, as well as describe the processes and equipment used. I have tried to avoid producing merely a catalogue of sterilizers and aseptic fillers. Statements are generally supported by references. Although the book deals mainly with milk and milk products, I hope that the information it contains will be useful to those dealing with other products, since the principles of processing are in general the same.
The study on UHT processing of milk: a versatile option for rural sector.
The goal of the process is to sterilize foods and beverages like milk, juice, dressing and yogurt, while ensuring that they keep their sensory appeal and. The usable life of milk can be extended for several days through techniques such as cooling which is the factor most likely to influence the quality of raw milk or fermentation. UHT Milk Processing. It is used for low acid above pH 4. Abstract: Ultra-high-temperature UHT processing of milk converts a very perishable natural product into a long-shelf-life product. Ira Nugerahani, M.

The raw milk quality, UHT process and storage conditions affect the stability. In this study, the stability of UHT milk produced in an indirect system was evaluated by studying changes in taste, colour, fat separation, fat adhesion to the package, sedimentation, gelation, heat coagulation time, pH and ethanol stability during storage for up to one year at different temperatures. Our results suggest that the changes observed at the different storage temperatures can be explained by different known mechanisms. Chemical and physical changes in the milk can lead to off-flavours, browning, fat separation, sediment formation or gelation during the subsequent storage Anema, ; Deeth, From a consumer perspective, the sensory attributes of the milk including taste and colour as well as visual stability such as fat separation, fat adhesion to the packaging material and sediment formation are of significant importance.

The heat used during the UHT process can cause Maillard browning and change the taste and smell of dairy products. UHT milk packaged in a sterile container has a typical unrefrigerated shelf life of six to nine months. In contrast, flash pasteurized milk has a shelf life of about two weeks from processing, or about one week from being put on sale. The most commonly applied technique to provide a safe and shelf-stable milk is heat treatment. However, without commercially available aseptic packaging systems to pack and store the product, such technology was not very useful in itself, and further development was stalled until the s.
The tubular exchanger unit is composed by modules of 4 mt. Advisory Committee: Ir. Milk to milk regeneration was used with both processes.
