Problems solved by technology

[0005] Garlic straw contains a lot of crude fiber, which has poor palatability. It is inconvenient to use directly and the effect is not good. In order to improve the effective utilization of garlic straw and improve its utilization effect, patent application number 200910025201.6 provides a garlic straw extract powder and extract method, the bioavailability is improved, the palatability is good, the active ingredients are easy to absorb, and the use effect is enhanced. Because the garlic straw contains allicin and other fat-soluble ingredients, this preparation method is difficult to effectively extract and cannot obtain ideal application effects.

Abstract

The invention discloses garlic straw extracts and a preparation method and application of the extracts to livestock and poultry feeds. The garlic straw extracts are characterized by firstly carrying out respective extraction with an organic solvent, and after solid-liquid separation, carrying out vacuum distillation on the solution to remove the solvent to obtain extracts; stirring the residues with hot water and extracting the residues with water, obtaining supernatant after filtration, centrifugal impurity removal and fine filtration, and then concentrating the supernatant to thick paste extracts with a thin film; and mixing the extracts obtained respectively, vacuum-drying the mixture, grinding the dried mixture into fine powder, sieving the fine powder with a 800-1200-mesh sieve, and packaging the sieved products, thus obtaining finished products. The garlic straw extracts and the preparation method have the following beneficial effects: the fat soluble and water soluble components can be fully and effectively extracted respectively by utilizing organic combination of the organic solvent and hot water extraction, and the beneficial effects of the garlic straws can be better retained; the extracts are beneficial to absorption and utilization of animals; and the process is simple, convenient and practicable and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a preparation method of garlic stalk extract, and also relates to the application of the extract in livestock and poultry feed. technical background [0002] Garlic has the unique effects of promoting qi stagnation and warming the spleen and stomach, detoxifying, killing insects, and stopping dysentery. At present, there are allicin and allicin products used in livestock and poultry and aquatic product breeding in China, which have obvious effects of attracting food and promoting growth. Especially in recent years, with the restriction of antibiotics in the breeding industry, garlic is used as a substitute for antibacterial agents. The research on the development and utilization of garlic is more in-depth. Garlic contains high protein and amino acids, as well as calcium, zinc, iron, copper and other nutrients, so that it is not only used as a single purpose for preventing ...
