Embodiment 1

[0029] Embodiment 1: A modified atmosphere packaging fresh-keeping storage method of lotus root, comprising the following steps:

[0030] (1) Clean the fresh lotus root, select the lotus root with no mechanical damage, white and tender meat, firm tissue, complete joints, and uniform maturity. After cleaning and selection, peel the lotus root with a stainless steel peeler, and soak it immediately after removing the stalk Carry out sterilizing treatment in sterilizing liquid for 8 minutes, repeatedly wash the surface of lotus root joints by rubbing with the hands while soaking, to fully remove bacteria on the surface of lotus root joints, said sterilizing liquid is a 100mg / L natamycin solution;

[0031] (2) After removing the lotus root from the sterilizing solution, soak it in the color protection solution for 5 minutes. The color protection solution is a composite color protection solution containing 1wt% sodium erythorbate, 0.5wt% citric acid and 0.05wt% cysteine liquid;

Abstract

The invention discloses a modified atmosphere packaging, preservation and storage method of lotus roots and application. The method includes the following steps of cleaning, selecting, sterilizing, color protection treatment, slicing, packaging, air mixing, air pumping, air inflation and hot sealing. By means of the method, packaging is easy and convenient, and packaging boxes, inflated gas and other raw materials are low in cost. Compared with existing fresh food e-commerce that cold-chain logistics has to be used for guaranteeing freshness, cost is obviously reduced. According to the method, the respiration function of fruits and vegetables and thin film air permeability of packaging materials are used for adjusting balance of gas components in a bag, so that the respiration function of fresh-cut lotus roots is reduced, surface browning of lotus root slices and increase of the total number of surface bacterial colonies are inhibited, and accordingly the storage life of the fresh-cut lotus roots is prolonged. The method is suitable for e-commerce selling. The fresh-cut lotus roots are stored in the environment at the normal temperature of 18-25 DEG C, and the lotus roots can be kept white and tender within 6-7 days. Adopted packaging boxes facilitate transportation, e-commerce selling is easy, and the method has good application prospects in the fresh-cut lotus root e-commerce selling field.

Description

technical field [0001] The invention belongs to the technical field of vegetable and fruit packaging and fresh-keeping, and in particular relates to a modified-atmosphere packaging fresh-keeping and storage method and application of lotus roots. Background technique [0002] Lotus root, Nymphaeaceae lotus is a large perennial aquatic herbaceous plant. It has a crisp and tender taste, slightly sweet taste, rich nutrition, and has medicinal value such as clearing heat, promoting body fluid, and nourishing stomach yin. At present, processing and storage can easily change its original natural flavor, and fresh-cut fruits and vegetables are increasingly in demand in the market due to their freshness and convenience, and have become one of the research hotspots. The international market has broad application prospects. [0003] Modified atmosphere packaging technology (MAP technology) is an advanced fresh-keeping packaging method that has emerged in recent years. It uses the resp...
