Abstract

The present invention relates to fish feed blending oil with an anti-oxidation function and belongs to the technical field of aquaculture. Rubber seed oil is used to partially replace fish oil; lycopene is added to prepare the feed blending oil. The fish feed blending oil comprises the following raw materials in weight percentages: 1.0-96.7% of rubber seed oil, 1.0-96.7% of fish oil, 3.2-6.5% of soybean lecithin and 0.1-0.2% of lycopene; the sum of the weight percentages of the raw materials of the blending oil is 100%; and the proportion of n-3:n-6 unsaturated fatty acids in the feed blendingoil is (0.7-3.1):1. The fish feed blending oil fully utilizes the by-product rubber seed oil in the rubber planting industry; the rubber seed oil is used as a fat source in fish feeds to replace partof soybean oil or the fish oil, saves the soybean oil or the fish oil which is a shortage feed oil, and reduces the cost of the fish feeds. Besides, the proportion of the n-3:n-6 unsaturated fatty acids in the prepared feed blending oil is suitable; the feed blending oil meets needs of fish for essential fatty acids of linoleic acid, alpha-linolenic acid, etc., and improves quality of aquatic products; the lycopene is added as a natural antioxidant in the feed blending oil, which overcomes shortcomings of the high-quality feed fat source of the rubber seed oil and also fully releases the bio-antioxidant activity of the lycopene.

Description

technical field [0001] The invention relates to a feed blending oil, in particular to a fish feed blending oil with anti-oxidation function, and belongs to the technical field of aquaculture. Background technique [0002] In general, fish can synthesize n-7 and n-9 series of unsaturated fatty acids, but not n-3 and n-6 ​​series of unsaturated fatty acids. Therefore, n-3 and n-6 ​​series of unsaturated fatty acids are the essential fatty acids of fish; n-3 series of unsaturated fatty acids are represented by α-linolenic acid, and n-6 ​​series of unsaturated fatty acids are represented by linoleic acid. These unsaturated fatty acids cannot be synthesized by fish themselves and must be ingested from feed. α-linolenic acid can be derived from eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in freshwater fish. [0003] Fish oil is a commercial raw material for aquafeeds and a high-quality fat source commonly used in freshwater fish feeds. The n-6 series unsaturated ...
