Embodiment 1

[0038] Example 1: Sterilized Milk Containing Fish Oil

[0039] Prepare the sterilized milk of this embodiment according to the following raw material weight ratios:

[0040] Milk 99.6843%

[0041] Emulsifier 0.1%

[0042] Fish Oil 0.2%

[0043] Sodium Vitamin C 0.015%

[0044] Vitamin E 0.0007%

[0045] The performance indicators of each raw material meet the requirements of relevant quality standards. Among them, the fish oil used meets the following index requirements:

[0046] 1. Sensory indicators

Pale yellow oily liquid. It has a fishy smell, no irritating bad taste.

2. Physical and chemical indicators

1. Acid value, mg KOH / g ≤0.6

2. Peroxide value, mEq / kg ≤2.0

3. Moisture content, % ≤ 1.0

4. DHA, mg / g ≥ 125

5. EPA, mg / g ≥ 80

6. Total n-3PUFA fatty acids, mg / g ≥ 270

7. Unsaponifiable matter, % ≤ 2.0

3. Hygienic indicators

1. Heavy metals (calculated as Pb), ppm ≤10

2. Arsenic, ppm ≤0....

Embodiment 2

[0064] Example 2: Sterilized milk containing fish oil

[0065] Prepare the sterilized milk of this embodiment according to the following raw material weight ratios:

[0066] Milk 99.7%

[0067] Emulsifier 0.1%

[0068] Fish Oil 0.2%

[0069]Compared with Example 1, the production method of this example is basically the same as that of Example 1 except that no antioxidant is added, and the sterilized milk product containing fish oil of this example is obtained.

[0070] The sterilized milk of the present embodiment is milky white as a finished product, has the pure fragrance and milk fragrance of milk, and has no peculiar smell. The tissue state is a uniform emulsion, slightly viscous, without delamination, and without visible mechanical impurities. In the sterilized milk product, the milk fat content is about 3.3%, the protein content is about 3.1%, the pH value is 6.7, the DHA content is about 25mg / 100g, and the EPA content is about 16mg / 100g.

Embodiment 3

[0085] Example 3: Flavored Milk Containing Fish Oil

[0086] Prepare the flavored milk of this embodiment according to the following raw material weight ratios:

[0087] Milk 800%

[0088] White sugar 5%

[0089] Emulsifier 0.1%

[0090] Thickener 0.1%

[0091] Fish Oil 0.08%

[0092] Sodium Vitamin C 0.02%

[0093] Fragrance 0.1%

[0094] water balance

[0095] The performance indicators of each raw material meet the requirements of relevant quality standards.

[0096] The production method of the flavored milk containing fish oil of the present embodiment mainly comprises the following steps:

[0097] 1. Raw milk (raw milk, raw milk) inspection, clean milk, pasteurization: It is required that the fat, protein, dry matter, freshness and other indicators meet the quality standards of raw milk, and the raw milk is removed through the clean milk process mechanical impurities; pasteurize the cleaned raw milk at 85°C±5°C / 15s, and cool the pasteurized raw milk to 1°C-8°C f...

Abstract

The invention provides a method for producing a liquid dairy product containing fish oil and a product thereof, in particular to the method for producing the liquid dairy product containing the fish oil through adding the fish oil into the liquid dairy product, and the liquid dairy product containing the fish oil which is produced and obtained according to the method. In the method, the fish oil is added into ingredient milk, is stirred and homogenized at a specific temperature to undergo pre-emulsification treatment, and is added into the liquid dairy product. Through the process design, the method can effectively reduce or eliminate poor flavor influence on the liquid dairy product brought by the addition of the fish oil and provide guarantee for realizing good stability, flavor and mouthfeel of the product in shelf life.

Description

technical field [0001] The present invention relates to a production technology of liquid dairy products, in particular to a method of adding fish oil to liquid dairy products to produce liquid dairy products containing fish oil and the liquid dairy products containing fish oil produced according to the method, belonging to Dairy processing field. Background technique [0002] In recent years, the liquid dairy industry has developed rapidly in our country. With the increasing demand of consumers for dietary nutrition and taste, it has become an important direction for the research and development of new liquid dairy products to find various functional food ingredients as research and development materials to add to liquid dairy products. [0003] Among the many functional food ingredients, fish oil has become the target of new product developers. Fish oil is a general term for all oily substances in fish, including body oil, liver oil and brain oil. Fish oil is rich in po...
