Feed raw material rich in energy and protein of omega-3 fatty acid and preparation method thereof

Abstract

The invention discloses a prescription for preparing an energy and protein feeding stuff raw material full of omega-3 fatty acid by using rubber seeds and a method thereof. The weight percentages of the omega-3 energy and protein feeding stuff raw materials are as follows: rubber seeds 20-80%, bean pulp, corn, rapeseed cake (pulp), cottonseed cake (pulp), rice bran and wheat bran or any combination thereof 20-80%. The preparation method is as follows: the exuviated and dried rubber seeds are mixed with various ingredients evenly and puffed, and then finished product is gained. By the invention, the nutrient components such as omega-3 fatty acid, energy and protein and the like contained in the rubber seeds can be used fully, meanwhile, anti-nutritional components such as hydrocyanic acid and the like contained in the rubber seeds are removed, the energy and protein raw materials full of omega-3 fatty acid widely accepted by the feeding stuff industry and applicable to various birds, livestock and fish feeding stuff are processed. The price of the energy and protein raw material is low.

Description

technical field [0001] The invention relates to a raw material for energy and protein feed rich in omega-3 fatty acids prepared from rubber seeds and a preparation method thereof. Background technique [0002] Omega-3 fatty acids are fatty acids with a carbon-carbon double bond at the third carbon atom at the end of the fatty acid carbon chain, such as α-linolenic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), etc. . Omega-3 fatty acids are not only essential fatty acids for humans and animals, but also have important health functions of lowering blood fat, promoting brain development, and maintaining cardiovascular health. [0003] At present, humans supplement omega-3 fatty acids mainly through direct intake of vegetable oils (such as flax oil) or animal oils (such as deep-sea fish oil) rich in omega-3 fatty acids. However, studies in recent years have shown that humans can also obtain omega-3 fatty acids that are more easily absorbed and transformed by a...

Problems solved by technology

[0007] First, rubber seeds contain a certain amount of cyanogenic glycosides. After animals eat them, they will release hydrocyanic acid under the action of digestive enzymes, which will seriously cause animal poisoning and even death.

[0008] Second, the oil content of rubber seeds is very high (up to 50%), which makes processing difficult, and there is almost no way to process them into a form acceptable to feed mills

First of all, it cannot be crushed, because the crushing will break out the oil, so that the crushed powder will recombine and stick, and block the screen of the grinder; secondly, it cannot be directly extruded or pressed, because the puffed or pressed are based on screw extrusion The principle requires that the material has a certain fiber content and internal friction, while the rubber seed kernel has low fiber content, high oil content, soft and slippery texture, and smoothbore phenomenon occurs in the extruder or oil press.

[0009] So far, there is no report in the prior art that directly uses rubber seeds as energy and protein feed materials rich in omega-3 fatty acids
