Abstract

The invention provides a fruit and vegetable fresh-keeping coating containing moutan bark and a preparation method of the fruit and vegetable fresh-keeping coating. The fruit and vegetable fresh-keeping coating is prepared from the following raw material components in parts by weight: 80-90 parts of moutan bark, 10- 25 parts of fresh kelp, 25-40 parts of hylocereus undatus, 0.5-2 parts of a gelatinizing agent and 2-5 parts of a thickener. According to the fruit and vegetable fresh-keeping coating, two kinds of extracts obtained from moutan bark and an alcohol extract of hylocereus undatus coordinately exert a broad-spectrum antibacterial effect, good antiseptic and antibacterial effects are achieved, and the fruit and vegetable fresh-keeping coating can be used instead of traditional chemical antiseptic agents and used for keeping fruits and vegetables fresh, the time of keeping fruits and vegetables fresh can be prolonged, and the antioxidant function of bodies can be enhanced; and mucus on the surface of fresh kelp is further used for extracting mannitol, and the refreshing sweet taste of mannitol is used for enhancing the comfort of the coating on mouths, and a stable protectivecoating is formed when the fruit and vegetable fresh-keeping coating is applied to the surfaces of fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping coating for fruits and vegetables containing moutan cortex and a preparation method thereof. Background technique [0002] Fruits and vegetables are an integral part of people's dietary structure, rich in vitamins, minerals and organic acids and other nutrients. After the fruits and vegetables are harvested, they are still undergoing respiration and transpiration, which will easily lead to the loss of water in the fruits and vegetables. After a period of time, there will be wilting phenomenon, which will affect the appearance and market value of fruits and vegetables. In addition, with the prolongation of storage time, fruits and vegetables are extremely vulnerable to external microorganisms and rot. Therefore, research on storage and preservation of fruits and vegetables has become an important topic of concern to the people. [0...
