Embodiment 1

[0044] Select 200g of green onion leaves that are complete, free from insects, without damage, with dead leaves and yellow leaves removed, and green in color. Commercially available stable chlorine dioxide (10% chlorine dioxide concentration, specially used for food processing, purchased from Beijing Huamao Tiancheng Technology Development Co., Ltd.) was diluted with distilled water to prepare a chlorine dioxide solution with a concentration of 25 mg / L. Soak the leaves of the shallots to be stored in a chlorine dioxide solution with a concentration of 25 mg / L for 10 minutes, drain, cover the surface of the shallots with absorbent paper, put them into polyethylene bags with small holes, and store them at 4°C for 15 days .

Embodiment 2

[0046] Except chlorine dioxide solution concentration is 50mg / L, other are all identical with embodiment 1.

Embodiment 3

[0048] Except chlorine dioxide solution concentration is 75mg / L, other are all identical with embodiment 1.

Abstract

The invention relates to the technical field of food fresh keeping, and provides a chlorine dioxide fresh keeping method of allium mongolicum regel. The allium mongolicum regel is soaked by a chlorinedioxide solution with the concentration being 25 to 75 mg / L; draining is performed; then, after water suction paper is covered on the surface of the allium mongolicum regel, the allium mongolicum regel is charged into a fresh keeping bag with holes for storage; chlorine dioxide belongs to a strong oxidizing agent; the chlorine dioxide stable series is used as a food additive. Through the study, the effects that when the chlorine dioxide solution with the concentration being 25 to 75 mg / L is used for treating the allium mongolicum regel, the storage time being about 15d can be obtained; the time is obviously prolonged through being compared with the storage time in the prior art. For the allium mongolicum regel treated by the fresh keeping method provided by the invention, the peak value occurrence time of nitrate is delayed by about 6d; in addition, the peak value concentration of the nitrate is also relatively reduced. Namely, the chlorine dioxide fresh keeping method of the allium mongolicum regel provided by the invention has the advantages that the nitrate peak value occurring time can be effectively delayed; the nitrate concentration can be reduced; the harmful substances inthe allium mongolicum regel can be reduced.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a chlorine dioxide preservation method for shallots. Background technique [0002] Modern storage and fresh-keeping technologies mainly include physical fresh-keeping methods, chemical fresh-keeping methods, and biological fresh-keeping methods. Among them, the physical fresh-keeping method is highly technical, and has the problems of large equipment investment and difficult maintenance; while the biological fresh-keeping method has not been widely used due to problems such as difficult identification of drug efficacy, complicated purification technology, and relatively high cost; It has the advantages of low cost, energy saving, and simple use, and is widely used, but the residue of chemical reagents and safety are questioned by consumers. [0003] Sand onion is affected by seasonal restrictions and the high water content of the leaves themselves. During storage and t...
