Milk fans know the dilemma: fresh milk tastes delicious, but it is rapidly fatal because of the contained germs. UHT milk is, however, a long shelf life, but she has lost the original milk flavor. maytag refrigerator water filter The solution is called "microfiltration": maytag refrigerator water filter instead of heating the milk is made here preserved by a ceramic filter. Food technologists at the Technical University Munich (TUM) as this procedure under the microscope. Their goal: Full taste with long shelf life - without loss of quality.
Heat makes milk, although durable, but they also changed parts of the healthy ingredients and the typical taste. Some innovative dairies are therefore switched maytag refrigerator water filter from conventional preservation methods on microfiltration: Sterilize the milk through fine ceramic filters. The product is in cool storage for longer shelf life than conventional fresh milk - while maintaining almost the flavor and vitamin spectrum of an untreated raw milk. As this process affects the product quality and how filtering works at all, but is not yet researched. Process engineers from the Social Science Research Center maytag refrigerator water filter Weihenstephan of TUM close this gap in order to better understand the method and optimize their performance further.
The principle of membrane separation technology sounds simple: Instead of killing microorganisms by intense heat, "seventh" to a majority of the nuclei contained in the raw milk through a ceramic filter. maytag refrigerator water filter When Pressing the milk through the filter, the bacteria are stored on and in the pore system from. But the devil is in the detail: the fat globules of milk have a similar size distribution as the bacteria contained. Therefore, the cream has to be removed in a first step before it can remove the remaining skim milk gently. And even that is not so simple: The smaller the ceramic pores, the less though microorganisms remain in the milk. But that, unfortunately, also remains an increasing proportion of milk proteins are in the filter.
In short: a predictable, effective as possible, but at the same time selective nucleation separation maytag refrigerator water filter with simultaneous preservation of the milk protein maytag refrigerator water filter is difficult to achieve. The fact that in the course of filtration also deposited milk components in the membrane and thus clog the filter, makes things even trickier. Therefore, the dairies grab far better in slightly larger pore sizes: Nevertheless, to ensure the safety of the consumer, maytag refrigerator water filter the microfiltration must currently be combined with a subsequent heating. This optimized combination method keeps milk cool up to three weeks fresh, without any vitamin loss or change in taste.
TUM researchers at the Department of Food Process Engineering and Dairy Technology of the Science Center Weihenstephan examine specifically the backgrounds, influencing factors and Abtrennmechanismen in microfiltration to get the implementation of the process better grip. Your goal: A scientifically-based filtration method by which to remove the seeds selectively and efficiently from the raw milk and thus make the subsequent heating process even gentler than before can.
The researchers vary by process engineers Prof. Kulozik in the experiment targeted pore size and structure of the ceramic filter as well as individual process parameters. In cooperation with the Department of Microbial Ecology (Prof. Scherer) they also have identified the dairy microorganisms that "slip through" by conventional filter membranes. Now, scientists can modify the filtration maytag refrigerator water filter process maytag refrigerator water filter specifically. The heating conditions they can adjust based on results maytag refrigerator water filter in order to improve the quality and storage stability of milk on.

Background: The interdisciplinary collaborative research project "Process optimization for the production of longer lasting fresh milk (ESL) using thermal maytag refrigerator water filter and membrane processes" (Project: AiF-FV 15047 N) is funded by the joint industrial research (Federal maytag refrigerator water filter Ministry of Economics and Technology / AiF) through the Research Association maytag refrigerator water filter of the Food Industry (FEI) promoted.
