[0041] Such as figure 1 Shown, a kind of modified atmosphere fresh-keeping production technology of wild four-leaf vegetable comprises the steps:

[0042] (1) Picking and pre-cooling of raw materials: pick the four-leaf vegetable raw materials, pass the acceptance and store in low temperature for cooling. Specifically, when picking four-leaf vegetable raw materials, we should not only pay attention to its freshness, but also pay attention to the surrounding ecological environment, so that the detection of pesticide residues can meet the requirements of GB2763-2012. Raw materials should be transported in time, be careful not to be bundled and squeezed, and should be handled with care, and packed in special plastic boxes. Food plastic turnover boxes should meet the requirements of GB / T5737-1995 to avoid deterioration. Accepted raw materials should be stored and cooled at (2±1)°C.

[0043] (2) Selection of raw materials: After pre-cooling, select four-leaf vegetables that meet ...

Abstract

The invention relates to a modified atmosphere freshness keeping production technology of wild Marsilea quadrifolia. The modified atmosphere freshness keeping production technology is characterized in that the technology comprises the following steps: picking a raw material, and pre-cooling; 2, choosing the raw material; 3, immersion: immersing in an immersion liquid composed of a material and water according to a volume ratio of 1:9-11, wherein the material comprises a 1% salt solution; 4, cleaning: removing dusts and silts; 5, dehydration: dehydrating by using a centrifuge; 6, disinfection: disinfecting through using an ultraviolet ray sterilizer; 7, modified atmosphere packaging: carrying out seal packaging of the Marsilea quadrifolia through using a freshness keeping film, and filling a mixed gas composed of O2, CO2 and N2 according to a certain ratio; and 8, refrigerating. The modified atmosphere freshness keeping production technology allows the Marsilea quadrifolia to be packaged by the mixed gas composed of O2, CO2 and N2 according to a certain ratio and to be stored at a low temperature, so the change of the nutritional components of the modified atmosphere Marsilea quadrifolia is reduced, and the original freshness, color and flavor of the Marsilea quadrifolia are furthest kept to realize the prolongation of the storage life and the regulation of the market surplus and deficiency.

Description

technical field [0001] The invention relates to a food preservation process, in particular to a vegetable preservation process. Background technique [0002] Four-leaf vegetable is a perennial aquatic apple family plant, also known as Ping, which is a wild plant that grows beside the road, in the field and by the stream in West Dongting Mountain, Suzhou, Jiangsu. The rhizome of the four-leaf vegetable grows slender and horizontal in water or mud, showing a creeping shape. In spring, the leaves grow from the nodes of the rhizome, with slender petioles, and four leaflets cross opposite each other. Tianzicao. The stems, leaves and seeds of the four-leaf vegetable can be used as medicine, which has the functions of antibacterial, anti-inflammatory, antipyretic, diuretic, prolactin, and blood circulation. Four-leaf vegetables contain a lot of vitamins and a variety of minerals, and are rich in nutrients. Its edible parts are tender stems and young leaves, which have a good fla...
