Problems solved by technology

Moreover, after fat is oxidized to a certain extent, it will affect the feedability of food and feed, and reduce the consumption rate.
[0003] Conventional powdering technology is likely to cause problems such as poor taste, mouthfeel and storage stability of powdered oils, and easy powder agglomeration for oils rich in unsaturated fatty acids. The use of decompression spray drying technology for powdering can effectively reduce the oxidation of unsaturated fatty acids, and there is no report on the preparation of tilapia oil powder by this method

Embodiment 1

[0025] Ingredients: 12g freshwater fish oil, 83g potato microporous starch, 0.01g soybean lecithin-Span80 composite emulsifier, 0.01g licorice antioxidant and propyl gallate composite antioxidant, 300g water.

[0026] Preparation method: adding potato microporous starch and soybean lecithin-Span80 composite emulsifier into water, heating to 80°C to dissolve, and obtaining solution A. Add fish oil, licorice antioxidant, and propyl gallate composite antioxidant to solution A under stirring, and perform emulsification and homogenization after stirring. The homogenization pressure is 15-25MPa, and the homogenization is performed twice for a total of 8 minutes. The emulsion is spray-dried, and the temperature in the drying chamber is controlled to 40-60°C, and the vacuum degree in the drying chamber is 6-12kPa. The dried fish oil powder is milky white with uniform particles, good fluidity and dispersibility, and the fish oil embedding rate reaches 90.1%.

Embodiment 2

[0028] Ingredients: 20g freshwater fish oil, 74g potato microporous starch, 0.1g sucrose ester-molecular distilled monoglyceride composite emulsifier, 0.4g citric acid, 0.01g licorice antioxidant and propyl gallate composite antioxidant, 250g water.

[0029] The preparation method is the same as that in Example 1. The obtained fish oil powder is milky white, has uniform particles, good fluidity and dispersion, and the fish oil embedding rate reaches 91.2%.

Embodiment 3

[0031] Take 32 g of freshwater fish oil, 58 g of potato microporous starch, 4.0 g of gelatin, 0.1 g of soybean lecithin-Span80 composite emulsifier, 0.01 g of licorice antioxidant and propyl gallate composite antioxidant, and 230 g of water.

[0032] The preparation method is the same as that in Example 1. The obtained fish oil powder is milky white, has uniform particles, good fluidity and dispersibility, and the fish oil embedding rate reaches 90.3%.

Abstract

The invention belongs to the technical field of microcapsule preparation, which particularly relates to a powdered tilapia oil and a production method thereof. A base material is formed by tilapia oil and powder. The base material, water, a compound emulsifying agent, an antioxidant and organic acids are mixed, homogenized, sprayed and dried to form the product. The powdered forming base material is carbohydrate or protein or the mixture of carbohydrate and protein. The invention has simple process and wide source of raw materials, effectively decreases the oxidization rate of the powdered oil by adding the antioxidant, and further improves the storage stability of the powdered oil by using the organic acids. The powdered oil has the advantages of good dispersivity, good odor, high stability, and the like.

Description

Technical field [0001] The invention belongs to the technical field of "microcapsule manufacturing", and specifically relates to a powdered tilapia oil used as a food or feed additive and a production method thereof. Background technique [0002] my country is rich in tilapia resources, and its output ranks first in the world. With the rapid development of tilapia aquaculture and processing industries, a large amount of tilapia processing waste has appeared. According to research, it has been found that tilapia processing waste has a high content of fats such as fish viscera. In terms of fatty acid composition, the content of ω3 series fatty acids is quite rich, and the content of three essential fatty acids of linolenic acid, linoleic acid and arachidonic acid is relatively high. In particular, it contains a certain amount of highly unsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have high medicinal, edible and feed value. Due to the ...
