Blueberry preservation method

Abstract

The invention provides a blueberry fresh-keeping method. The method comprises the following steps: (1) treatment before harvesting; and (2) treatment after harvesting. A blueberry fresh-keeping device used in the step (2) comprises a heat preservation box body, a storage fresh-keeping mechanism and a heat preservation box cover, the storage fresh-keeping mechanism is arranged in the heat preservation box body, the heat preservation box cover is installed on the upper end face of the heat preservation box body, a water storage cavity is formed in the lower side of the interior of the heat preservation box body, first ice storage cavities are symmetrically formed in the left side and the right side of the interior of the heat preservation box body, first rubber sealing plug strips are plugged into the upper end faces of the first ice storage cavities, first vacuum heat insulation plates are bonded to the right sides of the inner walls of the first ice storage cavities, and second ice storage cavities are symmetrically formed in the front side and the rear side of the interior of the heat preservation box body. By means of the design, the problem that original blueberries are prone to rot in the transferring process is solved, the structure is reasonable, the heat preservation and refrigeration capacity is achieved, the blueberries can be conveniently stored, and the situation that the blueberries are prone to rot in the transferring process is avoided.

Description

technical field [0001] The invention relates to a fresh-keeping method for blueberries, which belongs to the technical field of fresh-keeping blueberries. Background technique [0002] Blueberry fruit is rich in nutrients, which has the functions of preventing brain nerve aging, protecting eyesight, strengthening the heart, anti-cancer, softening blood vessels, enhancing human body immunity, etc., and has high nutritional components. Since the picking of blueberries is generally from May 20 to mid-July every year, the real-time temperature for picking is generally between 25-35 degrees Celsius. Because of the high temperature, the fresh fruits are easy to deteriorate after picking, so it is necessary to keep the freshness of the picked blueberries in time Storage; In addition, due to the high juice content and thin peel of blueberries, it is easy to squeeze and break the fresh fruit when transported in traditional vats. Even if it is transported in a small fruit box, it is e...

Problems solved by technology

Since the picking of blueberries is generally from May 20 to mid-July every year, the real-time temperature for picking is generally between 25-35 degrees Celsius. Because of the high temperature, the fresh fruits are easy to deteriorate after picking, so it is necessary to keep the freshness of the picked blueberries in time Storage; In addition, due to the high juice content and thin peel of blueberries, it is easy to squeeze and break the fresh fruit when transported in traditional vats. Even if it is transported in a small fruit box, it is easy to cause extrusion and juice leakage, resulting in juice soaking fresh fruit And make fresh fruit rotten, need a kind of blueberry fresh-keeping method badly now to solve the above-mentioned problem that occurs
