Problems solved by technology

However, this method does not consider the perishable situation of liquid milk during transportation, and the shelf life of the prepared liquid milk is still relatively short, and it is not easy to store, which causes a burden to the transportation process
[0005] Aiming at the high transportation cost of fresh milk, a fresh milk preparation method that can reduce the transportation cost should be selected, so that this method can avoid the high cost problems such as reverse osmosis, reduce cost and energy consumption, and ensure the taste of fresh milk At the same time increase the storage time of fresh milk

Abstract

The invention provides a fresh milk preparation method capable of reducing transportation cost, and relates to the technical field of fresh milk processing. The fresh milk preparation method capable of reducing transportation cost comprises the following steps: inspecting raw milk, and carrying out storing and pasteurizing; processing the pasteurized milk by adopting a low-temperature high-pressure falling-film concentration process; and then, carrying out cooling and storing so as to obtain the finished product, namely the concentrated milk. The fresh milk preparation method is low in cost and low in energy consumption; moreover, the fresh milk preparation method is capable of reducing volume of the fresh milk by 3-4 times with preservation time of the fresh milk prolonged under the premise of ensuring nutrients and taste of the fresh milk, thereby greatly reducing transportation cost of the fresh milk.

Description

technical field [0001] The invention relates to the technical field of fresh milk processing, in particular to a method for preparing fresh milk that reduces transportation costs. Background technique [0002] Fresh milk usually comes from raw cows or buffaloes. If the raw milk is not processed and stored in time after extrusion, it is easy to produce bacteria and deteriorate. It needs to be sterilized and processed into fresh milk for preservation. Consumers are very fond of fresh milk in terms of nutritional value and flavor, so fresh milk is widely used in many food industries as a healthy and nutritious raw material. However, the main milk source belt and main production area of ​​fresh milk in my country is in the north, and the storage and transportation conditions of fresh milk require refrigeration, so the long-distance transportation costs make it impossible to use fresh milk as a common food raw material for processing in many areas. Faced with such problems, in r...
