Embodiment 1

[0033] The refrigerated potatoes are washed first, and disinfected with 200ppm sodium hypochlorite or other disinfectants for 5 minutes, then peeled and processed into shreds, and disinfected with 50ppm sodium hypochlorite solution or other disinfectants, shaken dry or drain the surface water, and then put in 0mg / kg ( As a control), soak in 0.02mg / kg furfuryl thioacetate solution for 2 minutes, shake dry or drain the surface water, and pack it into a polyethylene fresh-keeping bag, fold the mouth of the bag, and put it in refrigerated conditions at 2-4°C Down. After 12, 24, and 72 hours, the control had obvious browning, severe browning, and severe browning and the surface lost water obviously, while the furfuryl thioacetate treated 12, 24, and 72 hours still had no browning and did not lose water , Slight browning after the 4th day without loss of water. The color measurement results are as follows:

Embodiment 2

[0038] With 0.04mg / kg furfuryl thioacetate solution, soak fresh-cut potato shreds for 3 minutes, and the others are the same as in Example 1. The control had obvious browning in 12 hours, and the surface obviously lost water and lost its commercial value, and then the browning was further aggravated, but there was no browning on the 4th day of the soaking treatment, and the surface did not lose water. water. On day 6, the browning score and absorbance value of the control were 5.0 and 0.668, while those of the treated were 1.33 and 0.148, respectively.

Embodiment 3

[0040] Soak fresh-cut potato shreds with 0.06 mg / kg furfuryl thioacetate solution for 5 minutes, and other operations are the same as in Example 1. Compared with obvious browning in 12 hours, the commercial value was lost, but the 6th day of soaking treatment did not have any browning and the surface did not lose water, and the 9th day had slight browning and slight water loss. On day 9, the browning score and absorbance value of the control were 5.0 and 0.691, respectively, while those of the treated were 1.47 and 0.161, respectively.

Abstract

The invention belongs to the technical field of freshness preservation of agricultural products, and relates to a new use of thioacetate compounds for inhibiting discoloration of fruit and vegetable tissues. The thioacetate compounds are used for preventing discoloration of fruits and vegetables, fruit and vegetable tissues or pulp. The thioacetate compound treatment comprises the steps of dipping, spraying, smearing, atomizing and fumigating the fruit and vegetable tissues with a solution of the thioacetate compounds or directly adding the thioacetate compounds into fruit and vegetable pulp;the mass concentration of the thioacetate compounds is in a range of 0.01-2.0 mg / kg. The thioacetate compounds have good effect and can effectively inhibit the discoloration of the fruit and vegetabletissues; the thioacetate compounds are safe, generally have the aroma of onion, garlic and fruits, can be used for preparing vegetables, fruits, coffee, dairy products, meat, seafood and the like, have wide application in food industry, and have no food safety problems; the thioacetate compounds can maintain the quality of fruits and vegetables and prolong the shelf life; the method is simple, easy to operate and promote, and suitable for treatment of small amount of samples and large-scale production; and the cost is low.

Description

technical field [0001] The invention belongs to the field of plant biotechnology, and relates to a new application of thioacetate compounds for inhibiting discoloration of fruit and vegetable tissues, and also relates to a new method for controlling discoloration of fruit and vegetable tissues. Background technique [0002] Injured fruit and vegetable tissues are prone to discoloration, such as potatoes, lotus root, yam, Jerusalem artichoke, burdock, garlic, apples, pears, peaches, lychees, lettuce and other fruits and vegetables cut and injured are prone to browning; cuts of postharvest flowers are prone to discoloration; Browning occurs. Discoloration not only affects the senses, reduces the value of commodities, but also causes the loss of some nutrients and functional components such as phenolic substances. [0003] At present, the method of suppressing the discoloration of fruit and vegetable tissues at home and abroad has the method of adding browning inhibitors, such...
