Abstract

The invention relates to a plant extract-soaked nano-microporous zinc oxide solid and a preparation method thereof. The plant extract is soaked in a nano-microporous zinc oxide solid and is prepared from the following components in parts by weight: 100 parts of nano-microporous zinc oxide powder, 1-3.5 parts of origanum vulgare leaf extract, 1-5.5 parts of shepherd's purse seed extract and 1-2.5 parts of eucalyptus leaf extract. Compared with the prior art, the plant extract provided by the embodiment of the invention is soaked in the nano-microporous zinc oxide solid, is green and non-toxic,has no side effect, can reduce the cost of raw materials, remarkably prolongs the effective antioxidant action time, and effectively slows down the oxidation failure of the feed.

Description

technical field [0001] The invention belongs to the field of feed processing, and in particular relates to a plant extract-impregnated nano-microporous zinc oxide solid and a preparation method thereof. Background technique [0002] Feed is easily affected by external light and heat during transportation and storage. Nutrients such as lipids in it are continuously oxidized, which may easily cause problems such as a decrease in the photosensitive properties of the feed, a decrease in nutritional value, a shortened storage period, and a decrease in palatability. Severe oxidation will lead to pigment oxidation, protein destruction and feed rancidity, and even has a certain degree of toxicity, which will affect the health of animals in the slightest and lead to a decline in production performance, and will endanger human life in severe cases. [0003] Feed antioxidants can avoid the oxidation of feed. At present, the commonly used antioxidants in feed industry at home and abroad...
