Embodiment 1

[0011] Embodiment 1, a kind of reducing SO 2 The processing method that antistaling agent affects on the color of cherry pulp, the concrete steps are as follows:

[0012] Before cherry picking, between 10 and 12 o'clock every night, irradiate the cherry fruit on the tree with ultraviolet light, and the illumination intensity is 1mW / cm 2 , each irradiation time is 40 minutes, continuous irradiation for 3 days, and then picking cherries with handles, using SO 2 Preservatives to preserve cherries.

Embodiment 2

[0013] Embodiment 2, a kind of reducing SO 2 The processing method that antistaling agent affects on the color of cherry pulp, the concrete steps are as follows:

[0014] Before cherry picking, between 10 and 12 o'clock every night, irradiate the cherry fruits on the tree with ultraviolet light, and the illumination intensity is 1.1mW / cm 2 , each irradiation time is 42 minutes, continuous irradiation for 3 days, and then picking cherries with handles, using SO 2 Preservatives to preserve cherries.

Embodiment 3

[0015] Embodiment 3, a kind of reducing SO 2 The processing method that antistaling agent affects on the color of cherry pulp, the concrete steps are as follows:

[0016] Before cherry picking, between 10 and 12 o'clock every night, the cherry fruit on the tree is irradiated with ultraviolet light, and the illumination is 1.2mW / cm 2 , each irradiation time is 44 minutes, continuous irradiation for 3 days, and then picking cherries with handles, using SO 2 Preservatives to preserve cherries.

Abstract

The invention relates to the technical field of food preservation, in particular to a treatment method for reducing the influence of SO2 preservatives on cherry pulp colors. Before cherry fruits are picked, the cherry fruits on trees are irradiated by ultraviolet lamps with illumination of 1-1.5mW / cm<2> at 10-12 o'clock every night for 40-50 minutes, the cherry fruits are continuously irradiated for 3 days, and the cherry fruits with stems are picked and preserved by the SO2 preservatives. Combination of anthocyanin and organic acid in the cherry fruits is promoted, acidized anthocyanin is formed, the anthocyanin is modified, stability of the anthocyanin is improved, the influence of SO2 on the anthocyanin is reduced, and cherry colors can keep a certain stability in the later period of preservation of the cherry fruits by the SO2 preservatives.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a method for reducing SO 2 Treatment method for the effect of similar preservatives on the color of cherry pulp. Background technique [0002] Cherry fruit skin is thin and juicy. When harvested in high temperature and high humidity season, it is susceptible to disease, rot, and is not resistant to transportation. The main reason for cherry fruit rot after harvest is due to the pathogenic action of pathogenic microorganisms. Therefore, it is safe and effective to use Preservatives are the main method to control postharvest rot, SO 2 Antistaling agent is a kind of antistaling agent commonly used in postharvest cherry insurance, SO 2 Preservatives are good for maintaining the normal physiological level of cherries in the early stage (that is, the preservation effect is better), but in the later preservation process, it is easy to cause changes in the surface color of ...
