Problems solved by technology

[0004] In the prior art, the harvested bananas are generally treated with chemical preservatives. The freshness preservation effect is relatively obvious, but there are chemical substance residues, drug resistance and environmental protection problems, which are not conducive to the health of consumers after use.
With the rise of green food and organic food, people's demand for pollution-free, pollution-free, high-quality bananas is increasing rapidly, and the use of chemical preservatives and traditional fresh-keeping methods has received more and more restrictions

Abstract

The invention discloses a method for prolonging the fresh keeping time of bananas during storage and transportation. The method comprises the following steps of performing harvesting treatment, performing cleaning, performing sterilizing and fresh keeping treatment, performing packaging and box sealing, performing storage and transportation and the like. A sterilizing fresh keeping agent adopted by the method disclosed by the invention is prepared through mixing a plant extract with auxiliary materials, wherein the plant extract is prepared through water extraction of the following raw materials: fennel seeds, lesser galangal rhizomes, purslane herbs, heartleaf houttuynia herbs, Chinese pulsatilla roots, mulberry leaves and camphortree leaves, and the auxiliary materials are obtained through mixing the following raw materials of sucrose fatty acid ester with chitosan, xanthan gum, sorbic acid and lysozyme. The fresh keeping technique adopted by the method disclosed by the invention is high in pertinence, safe, environmental-friendly, good in fresh keeping effects, and long in fresh keeping time, and is suitable for long-distance storage and transportation.

Description

technical field [0001] The invention belongs to the technical field of fruit preservation, and in particular relates to a method for extending the storage and transportation preservation period of bananas. Background technique [0002] Banana is one of tropical and subtropical famous fruits. Its yield is high, the pulp is sweet and smooth, rich in nutrients, and is deeply loved by people. It is a fresh fruit that is supplied all year round in domestic and foreign markets. Fresh bananas have a scavenging effect on active oxygen free radicals. Eating bananas regularly can enhance the antioxidant capacity of human plasma, play a positive role in preventing cardiovascular diseases and delaying aging, and has certain medicinal values, such as clearing away heat, moistening the intestines, and detoxifying , treatment of fever, constipation and so on. [0003] my country's banana planting areas are concentrated in tropical regions within 30 degrees north latitude, respectively in ...
