Fruity flavored fermented milk and preparation method thereof

Abstract

The present invention discloses flavored fermented milk. The flavored fermented milk consists of the following raw material: raw milk, white granulated sugar, fruit jam and probiotics. The method of preparing the flavored fermented milk consists of the following steps: (1) degreasing: the raw milk is subjected to a centrifugal degreasing treatment and separated single cream is introduced into a temporary storage tank for standby applications; (2) fermenting: after the degreasing in the step (1), the degreased raw milk is subjected to sterilization, and the sterilized raw milk is fermented; (3) homogenizing and sterilizing: the white granulated sugar is added into the single cream obtained in the step (1), the mixture is homogenized, and the homogenized mixture is sterilized; (4) whey removing: the fermented liquid obtained in the step (2) is subjected to a demulsification and the demulsified fermented liquid is subjected to the whey removing treatment; and (5) filling: the sterile and sugar-added single cream and the whey removed fermented liquid are mixed evenly, sauce material ingredients are added into the mixture, the mixture is subjected to the filling, the filled mixture is subjected to a temperature lowering, the temperature lowered mixture is subjected to a after-ripening, and the flavored fermented milk is obtained. Advantages are as follows: the prepared flavored fermented milk is high in proteins, develops a new taste, and free of food additives, ensures the purely natural raw material ingredients, and is free of nutrient component losses.

Description

technical field [0001] The invention relates to the technical field of dairy products, in particular to fruity flavor fermented milk and a preparation method thereof. Background technique [0002] Flavored fermented milk is made of more than 80% raw cow (sheep) milk or milk powder, and other raw materials are added. After sterilization and fermentation, the pH value is lowered. Food additives, nutritional enhancers, fruits and vegetables, Products made from grains etc. [0003] Flavored fermented milk is one of the two main types of fermented milk, so it has the common nutritional value of fermented milk. In addition to being rich in protein, sugar, minerals and various vitamins, it is also due to the action of lactic acid bacteria. Lactose, which is not easy to be digested and absorbed by the human body, is turned into lactic acid, which can inhibit the growth and reproduction of harmful microorganisms in the intestinal tract and promote the digestion and absorption of the...

Problems solved by technology

[0004] However, some experts believe that the addition of fruit or fruit and vegetable juices to flavored fermented milk will dilute the original nutrients in the milk, so the nutritional value is not as high as that of fermented milk.

In addition, there are some flavored fermented milks on the market that can be stored at room temperature. Because they are reheated after fermentation, the shelf life is extended and there is no need for refrigeration. Although nutrients such as protein and vitamins are retained, the live bacteria in them have been killed. The value has decreased, (all kinds of yogurt flood the market, keep your eyes open to see the category Xinhuanet [cited date 2014-12-18])
