Green and energy-saving method for promoting healing of mechanical injury wounds of sweet potatoes

Abstract

The invention discloses a green and energy-saving method for promoting healing of mechanical injury wounds of sweet potatoes. The method comprises the following steps of S1, performing selecting: manually selecting sweet potatoes with mechanical injury; S2, loading the sweet potatoes into a basket: loading the selected sweet potatoes into a turnover basket; S3, performing warehousing: firstly laying an isolation layer on the ground of a storage warehouse, and then performing stacking on the turnover baskets filled with the sweet potatoes on the isolation layer from inside to outside and from bottom to top; S4, performing temperature and humidity management, wherein in the healing period, the temperature in the storage warehouse is maintained at 24-27 DEG C, and the relative humidity is maintained at 85-90%; and S5, performing storage management: after the healing period is ended, reducing the temperature in the storage warehouse to 12 DEG C, and performing conventional storage. According to the green and energy-saving method for promoting healing of the mechanical damage wounds of the sweet potatoes, on the basis of reducing energy consumption and being not suitable for chemical agents, the situation that the sweet potatoes are rotten in the storage and fresh-keeping process is reduced, and the storage safety and the eating safety of the sweet potatoes are guaranteed.

Description

Technical field [0001] The invention relates to a sweet potato storage and fresh-keeping technology, in particular to a green energy-saving method for promoting the healing of mechanically damaged sweet potato wounds. Background technique [0002] Sweet potato is the seventh largest in the world and the fourth most important food crop in my country. It has high nutritional value and is deeply loved by consumers. Due to the strong seasonality of sweet potato production, it is in contradiction with the annual supply of the market. At the same time, after a period of storage of sweet potato after harvest, the starch in the potato chunks is converted into sugar, which can improve the flavor and taste of the sweet potato. Therefore, it is of great significance to study the preservation of sweet potato. [0003] Sweet potato has the characteristics of large volume, high water content, soft tissue, thin skin, etc. When harvesting, manual planing, ploughing, and tractor-machined digging ...

AI Technical Summary

Problems solved by technology

) put the harvested sweet potatoes at a high temperature of about 36°C, and the wound can basically heal itself after 4 to 5 days. This method usually requires setting up a special high-temperature callus bank, and the callus bank needs to consume a lot of energy to maintain a high temperature state , increase the storage cost, and the potato pieces are easy to lose water under high temperature, and it is also easy to induce some high-temperature diseases

The second is to use the chemical healing method to apply chemical agents on the mechanical wounds of potato pieces to achieve wound disinfection and sterilization, and prevent the wounds from rotting due to bacterial infection. This method is likely to cause excessive chemical agent residues and affect the food safety of sweet potatoes
