Problems solved by technology

[0004] The cassava storage method in the prior art usually needs to be isolated from oxygen or cryogenically frozen for storage, wherein the storage method of isolating oxygen by wax sealing or vacuum packaging significantly increases storage costs and processing procedures, and the storage environment required by the cryogenically frozen storage method is relatively high. Strict, high maintenance costs, and fresh potatoes need to be used after thawing, the flavor is easy to lose, resulting in a decline in quality

Abstract

The invention relates to a decompression storage method of tapioca roots, which comprises the following specific operation steps of: 1, cleaning: simply cleaning fresh tapioca roots, and after removing silt on the surfaces of the tapioca roots, carrying out air-drying for later use; 2, pre-cooling: carrying out pre-cooling processing on the tapioca roots with ice water with the temperature of 4 to9 DEG C so as to cool the tapioca roots; 3, sterilization: after air-drying the pre-cooled tapioca roots, placing the tapioca roots into a storage box, and carrying out surface sterilization treatment on the tapioca roots under the closed condition; 4, decompression: decompressing the storage box by using a vacuum pump to reduce the pressure of the storage box to 0.4 to 0.7 atmospheric pressure;and 5, ventilation: carrying out pressurization and ventilation on the storage box at intervals of preset time, and repeating the operations of the step 3 and the step 4 after the air pressure in thestorage box is balanced with the external air pressure. The decompression storage method of the tapioca roots, which is disclosed by the invention, has the advantages of low storage cost, low storageenvironment requirement and good storage effect.

Description

technical field [0001] The invention relates to the technical field of agricultural production and transportation, in particular to a method for storing cassava tubers under reduced pressure. Background technique [0002] Cassava (Manihot esculenta Crantz) belongs to Euphorbiaceae (Euphorbiaceae). The three major food crops and the sixth largest food crop in the world, known as the "king of starch", are the rations of nearly one billion people in the world. In addition, cassava has excellent characteristics such as rough growth, easy cultivation, high yield and four-season harvesting. With the development of the cassava industry, the use of cassava is gradually diversified, as industrial raw materials such as feed, starch, and fuel ethanol. [0003] Due to the crisp and tender tissues of fresh cassava and high water content, "post-harvest physiological deterioration" is prone to occur during processing and storage, resulting in dehydration, browning, and rot of roots, and ...
