Problems solved by technology

[0003] Yet, there is following problem when preparing the dairy product of green apple flavor at present: 1, contain a large amount of malic acid in green apple concentrated juice, add before carrying out pasteurization and can influence the fermentation of yoghurt, easily produce whey to separate out etc. Stable situation; 2. Green apple essence is added in the yogurt ingredients, after pasteurization treatment, the flavor of the essence will change, resulting in unsatisfactory flavor of the final product

Embodiment 1

[0046] This example provides a method for preparing green apple-flavored fermented milk, including two processes of fruit juice preparation and fermented milk preparation, specifically including the following steps:

[0047] 1. Juice preparation:

[0048] (1) Select fresh green apples, wash, peel, split, core, precook and set aside;

[0049] (2) Boil the treated green apples with a mixed solution containing 0.3wt% ascorbic acid and 0.5wt% citric acid (that is, keep the temperature at 100°C) for 90s, add water to make a slurry, and soften the slurry for 120min in an ultrasonic device with an ultrasonic power of 800W , then add enzyme preparation, and enzymolyze in a water bath at 55°C for 1 hour to obtain green apple pulp;

[0050] (3) Weigh 0.5g carboxymethyl chitosan, add 4ml, 1% acetic acid solution and stir to form a paste, then add 5g activated clay, stir in a constant temperature water bath at 60°C for 6h, suction filter and dry to obtain carboxymethyl chitosan chitosan...

Embodiment 2

[0058] This example provides a method for preparing green apple-flavored fermented milk, including two processes of fruit juice preparation and fermented milk preparation, specifically including the following steps:

[0059] 1, fruit juice preparation: adopt the fruit juice preparation method of embodiment 1, obtain concentrated green apple juice.

[0060] 2. Preparation of fermented milk:

[0061] (1) Ingredients: 919.1g fresh milk, 45g white granulated sugar, 20g fructose syrup, 0.3g polydextrose, 6.8g compound stabilizer (made of acetylated distarch adipate 6g, agar 0.3g and monostearin 0.5g glyceride), 8g concentrated green apple juice (without water), 0.8g green apple essence, mixed at 55°C for 25min to obtain the base material;

[0063] (3) Cool the sterilized base material to 40-43°C, add 0.02g starter (comprising 0.01g each of Streptococ...

Embodiment 3

[0066] This example provides a method for preparing green apple-flavored fermented milk, including two processes of fruit juice preparation and fermented milk preparation, specifically including the following steps:

[0067] 1, fruit juice preparation: adopt the fruit juice preparation method of embodiment 1, obtain concentrated green apple juice.

[0068] 2. Preparation of fermented milk:

[0069] (1) Batching: the composition of the base material is the same as in Example 1, and each component is stirred at 55° C. for 25 min to obtain the base material;

[0070] (2) The base material is degassed at 65°C and 18MPa, then homogenized at 30 / 180bar pressure, and then sterilized at 96°C for 300s;

[0071] (3) Cool the sterilized base material to 40-43°C, add 0.02g starter (comprising 0.01g each of Streptococcus thermophilus and Lactobacillus bulgaricus), and enter into a fermenter filled with nitrogen through a sterile filter device. Ferment at 43°C, stop fermentation when the a...

Abstract

The invention provides green apple flavored fermented milk and a preparation method thereof. The preparation method comprises the following steps that green apples are boiled, blanched, pulped, subjected to ultrasonic treatment and enzymolysis, a carboxymethyl chitosan / activated clay compound is added, clarifying is carried out to obtain concentrated green apple juice; the concentrated green apple juice is mixed with raw milk, green apple essence, polydextrose and a compound stabilizer, and degassing, homogenizing, sterilizing and fermenting are carried out to obtain the green apple flavored fermented milk; the compound stabilizer is prepared from agar, acetylated distarch adipate and glyceryl monostearate; the base material is prepared from 0.5%-1.2% concentrated green apple juice and 0.05%-0.1% green apple essence; and the sterilization temperature ranges from 90 DEG C to 96 DEG C, and the sterilization time ranges from 285 seconds to 300 seconds. The green apple flavored fermented milk is prepared by the preparation method. The green apple flavored fermented milk is high in stability, uniform in texture and relatively good in flavor and taste.

Description

technical field [0001] The invention relates to the field of dairy products, in particular to green apple-flavored fermented milk and a preparation method thereof. Background technique [0002] Yogurt combines the multiple nutrients of milk, strains and fermented products, and is recognized as a healthy food. Yogurt has high nutritional value, is easier to digest and absorb than fresh milk, regulates gastrointestinal flora, improves the body's immune system, and improves metabolic disorders of lactose intolerance. Green apple is a kind of apple, which is rich in vitamins, minerals and rich dietary fiber. Compared with other fruits, green apple can provide negligible fat, almost no protein, and few calories. An average of 100 grams has only 60 calories. And it is rich in malic acid, which can effectively disperse the fat accumulated in the body, thereby preventing obesity. [0003] Yet, there is following problem when preparing the dairy product of green apple flavor at pr...
