Problems solved by technology

[0003] Sand onion is a leafy vegetable with high water content and large leaf surface area. During the harvesting process, it is inevitably mechanically damaged, which accelerates the loss of water and nutrients; during long-distance transportation, if not used Reasonable storage and preservation methods can easily cause the loss of nutrients, the decline of sensory quality, and seriously cause rot and loss of commercial value.

Abstract

The invention relates to the technical field of food preservation, and discloses an allium mongolicum regel compound preservative containing nobiletin. The allium mongolicum regel compound preservative is mixed by the nobiletin, chitosan and water. Compared with the prior art, the allium mongolicum regel compound preservative has the following beneficial effects that a technology is simple and operation is convenient, the utilization of the compound preservative has a better storage effect than the utilization of the utilization of the preservative containing single nobiletin and chitosan, a storage period can be prolonged by about five days, and the allium mongolicum regel compound preservative is suitable for industrial production. The allium mongolicum regel compound preservative, whichis prepared by the method disclosed by the invention, containing the nobiletin can guarantee a low weight loss ratio and rotting rate under a high sensory evaluation score; meanwhile, nitrate and nitrite can be effectively prevented from being generated in an allium mongolicum regel storage and transportation process, vegetables can guarantee high safety quality, during a storage period, a respiratory function can be inhibited, the consumption of nutrient substances is reduced, an a high nutrient value and high commercial quality can be kept.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a nobiletin-containing compound antistaling agent for shallots and its preparation method and application method. Background technique [0002] Sand onion has become a valuable wild natural resource in the Inner Mongolia Autonomous Region. Planting sand onion is an important way for local farmers and herdsmen to get rid of poverty and become rich. It contains various nutrients and trace elements needed by the human body, and also has high medicinal value After the sand onion is harvested, it is very vulnerable to the infection of pathogens and the loss of water and nutrients, and it is accompanied by rot. Therefore, the long-distance transportation and fresh-keeping technical problems of sand onions have become increasingly prominent, which has become a major bottleneck problem restricting the development of the industry. [0003] Sand onion is a leafy vege...
