Problems solved by technology

At present, anticorrosion and fresh-keeping treatment mainly use chemical reagents and pesticides such as thiophanate-methyl, carbendazim, benlaite, tekto, imazole, etc. These drugs have relatively large toxic residues, and long-term use will not only endanger human health, pollute the environment, and also make disease fungi develop resistance
In recent years, with the attention to food safety issues, people have turned their attention to broader research fields, such as safer food preservatives, natural plant antibacterial compounds, etc. Overall, although various treatment methods have achieved certain results effect, but they all have certain limitations or shortcomings, so finding safe, economical and efficient antiseptic fresh-keeping products or technical means is still the focus of citrus fresh-keeping work

Abstract

The invention provides a citrus fruit bleached lac antistaling agent, which is characterized by comprising the following raw materials by mass percentage: bleached lac solution, 10.0 to 40.0 percent; silicon oxide nano-material, 1.1 to 2.0 percent; clove extract, 2.0 to 13.0 percent; cinnamon extract, 2.0 to 13.0 percent; magnolia bark extract, 2.0 to 13.0 percent; garlic extract, 2.0 to 13.0 percent; gibberellin, 50 to 200ppm; the rest is water. The citrus fruit bleached lac antistaling agent not only can effectively restrain moisture loss of the citrus fruit, reduce the respiration intensity, delay fruit ripening and restrain impregnating of pathogens and spoilage organisms which can cause mass decomposition, but also can form a membrane on the fruit surface so as to improve the fruit appearance and increase the value of commodity. The antistaling agent has advantages of low cost, simpleness and practicality and relatively high utility value.

Description

technical field [0001] The invention relates to a fruit fresh-keeping agent, in particular to a citrus bleached shellac fresh-keeping agent, which belongs to the technical field of crop fresh-keeping. technical background [0002] Citrus is one of the main fruits in my country. It belongs to a class of fruits with a large population. It can be divided into five categories according to its fruit size and character, namely tangerines, tangerines (easy to peel), oranges, lemons and pomelo. Citrus is a non-respiratory climacteric fruit, and the postharvest fruit will not produce respiratory peak due to changes in storage and transportation environmental conditions, so that the fruit will suddenly enter the senility period. However, the storage of citrus is different from other fruits in that no matter when and where the fruit is harvested, it must undergo antiseptic treatment, otherwise it will cause a lot of rot during storage and transportation. [0003] The fruit of citrus w...
