Abstract

The invention relates to a modified-atmosphere packaging and fresh keeping method suitable for storage and transportation of fresh sweet cherries. The characteristic that sweet cherries can resistanthigh-concentration CO2 is adopted, the fresh sweet cherries are precooled, then the precooled fresh sweet cherries are placed in a modified-atmosphere packaging bag for sealing, and storage, transportation or direct sales under the condition of minus 1 to 1 DEG C and relative humidity being 90-95% are performed. Under the condition of being free from inflation, CO2 generated in the respiration process of fruits is used, so that a good effect can be achieved, and favorable storage quality of the sweet cherries can be maintained. The storage period of the sweet cherry fruits can be effectively prolonged by 2-5 days, the problem of fresh keeping of the sweet cherry fruits is solved, and the commodity value of the sweet cherries can be increased.

Description

technical field [0001] The invention belongs to the field of storage and transportation devices, and in particular relates to a method for storing and transporting fresh sweet cherry fruits with spontaneous modified atmosphere packaging. Background technique [0002] Sweet cherry is one of the high-quality and high-grade fresh fruits that mature earlier. It has high nutritional value and economic value, and is deeply loved by consumers. Sweet cherries are rich in iron, anthocyanins, vitamin E and other substances, which have the functions of anti-anemia, regulating Qi, expelling wind and dampness, astringent and pain relief, strengthening the spleen and stomach, and it is also a natural antioxidant, which is rich in Anthocyanins have the functions of reducing the incidence of inflammation, reducing swelling, and relieving pain. However, the growth period of sweet cherry fruit is very short, the skin is thin and juicy, it can only be stored for 3-5 days at room temperature, ...
