Liquid dairy product containing linoleic acid and linolenic acid and preparation method thereof

Abstract

The invention provides a liquid dairy product containing linoleic acid and linolenic acid. The linoleic acid exists in the liquid dairy product in a plant oil form; and the liquid dairy product comprises the following components by weight: 400 to 900 portions of liquid milk, 30 to 50 portions of plant oil, 4 to 6 portions of linolenic acid, 1.0 to 3.5 portions of emulsifier and 0.5 to 1.5 portions of thickening agent. The liquid dairy product is added with the linoleic acid and the linolenic acid, and is added with the emulsifier and the thickening agent in proper proportion to successively solve the problem that the quality of the components added is not stable in the ultra-temperature liquid milk, so that the product has normal flavor and mouthfeel and stable quality.

AI Technical Summary

Problems solved by technology

[0006] In the market, milk powders are currently the main dairy products added with linoleic acid and linolenic acid. Liquid milk for infants and children over three years old, the main reason is that a certain amount of linoleic acid or vegetable oil and linolenic acid are added to ultra-high temperature sterilized liquid milk products, which are prone to liquid milk fat due to their own characteristics. Separation and "oil floating" phenomenon, poor stability, directly affect product uniformity, currently not widely used in liquid milk products

[0007] There is an application number of 200610098409.7, a Chinese patent application titled "a liquid milk suitable for children aged 1-3 and its production method", which discloses that the content of linoleic acid is 40-80mg / 100g (milk ) and so on, however, the amount of linoleic acid and linolenic acid added in this application is lower than the amount recommended by the Nutrition Society and nutritionists, because if the amount of linoleic acid and linolenic acid reaches the recommended amount, it will bring There are a series of problems such as poor product stability.
