Abstract

The invention belongs to the technical field of agricultural product preservation, and particularly relates to an agricultural product preservation extract and application thereof in agricultural product preservation. The agricultural product preservation extract is an extract extracted from plant or animal agricultural products, the extract is used as a preservative after being uniformly mixed with water or other solvents, the extract can be covered on the surfaces of the agricultural products to form films by methods of spraying, soaking, brushing and the like, the treated agricultural products can be stored by packaging or other methods after being aired, or slow release microcapsules, preservation films, preservation boxes and the like block most of the oxygen from entering the interior of the agricultural products and inhibit the ripening process of the agricultural products, so that the effects of prolonging the storage and preservation periods are achieved. The preservation extract provided by the invention is obtained by self-extraction of the agricultural products, is further used for self-preservation treatment of the agricultural products, is a natural substance, does not contain any additive or exogenous compound, is efficient, safe and non-toxic, and does not influence the taste and nutritional ingredients of the agricultural products.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping agricultural products, and specifically relates to a kind of original ecological agricultural products (fruits, vegetables, grain and oil, sugars, medicinal materials, edible fungi, seasonings, spices, forest products, cut flowers, eggs, livestock and poultry meat, aquatic products) , animal subsidiary agricultural products, etc.) fresh-keeping extract and its application in agricultural product preservation. Background technique [0002] Agricultural products include plant agricultural products and animal agricultural products. Plant agricultural products, such as fruits, vegetables and nuts, are rich in nutrients and are indispensable food in people's life, and they are also one of the sources for people to obtain various nutrients. Fruit refers to juicy and mostly sweet plant fruit that can be eaten raw. It is rich in nutrition and is an indispensable food in people's life, and it is als...
