Abstract

The invention belongs to the technical field of fresh keeping of fruits and vegetables, and particularly discloses a fresh keeping method of strawberries. The fresh keeping method comprises the following steps of (1) picking strawberries, and thoroughly flushing the picked strawberries; (2) treating the flushed strawberries with ultrasonic waves of different frequencies; (3) performing soaking treatment on the treated strawberries with fresh keeping liquid, wherein the fresh keeping liquid comprises the following raw material components in parts by weight: 3-7 parts of herba pyrolae, 2-5 partsof sessile alternanthera herbs, 2-5 parts of cloves, 1-4 parts of litsea cubeba (Lour.) Pers., and 1-2 parts of viscid germander herbs; (4) treating the strawberries with water vapor; and (5) performing low-temperature storage on the treated strawberries. According to the fresh keeping method disclosed by the invention, the storage time of the strawberries can be effectively prolonged, and the fresh keeping effect is good.

Description

【Technical field】 [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a fresh-keeping method of strawberries. 【Background technique】 [0002] Strawberry belongs to Rosaceae and is an evergreen herbaceous plant for many years. Strawberry fruit is bright in color, unique in flavor and rich in nutrition. It has certain effects in antibacterial, anti-tumor and anti-HIV virus. However, the strawberry skin is thin and has a large water content. It is a non-respiratory climacteric fruit with a very short postharvest life. Due to the high temperature and rain in the harvest season, the postharvest fruit has a huge water content, a strong metabolism, is sensitive to fungi, and is extremely susceptible to mechanical damage. Infection by damage and germs will lead to rot and loss of commodity value, and it can only be stored for 1-2 days at room temperature. Therefore, how to prolong the storage and fresh-keeping time of str...
