Preservative for Huangguan pears

Abstract

The invention discloses a preservative for Huangguan pears and belongs to the field of storage and preservation of fruits. The preservative for Huangguan pears contains any one or the mixture of two of salicylic acid and betaine, and also contains an antioxidant and sugar. The invention can effectively reduce moisture loss of the Huangguan pears in a cold storage period, reduce the incidence rateof russeting on the surfaces of fruits, maintains brightness, cleanness and freshness of the fruit surfaces and good fruit flavor, and has the advantages of no toxicity, no harm, simple preparation method, low cost, convenient use and good preservation effects.

Description

technical field [0001] The invention relates to a fruit fresh-keeping agent, in particular to a pear fresh-keeping agent, and belongs to the field of fruit storage and fresh-keeping. Background technique [0002] Huangguan pear, which belongs to the early-maturing pear variety, is widely cultivated in northern my country. Its fruit is of good quality and is very popular among people. However, the fruit of Huangguan pear is easy to soften and rot at room temperature, so it should not be stored for a long time, and must be refrigerated. However, when the fruit of this variety is refrigerated immediately after harvesting, brown spots on the fruit surface are often prone to occur, which seriously reduces the shelf quality and commodity value. Then it affects the enthusiasm of post-harvest storage and sellers, and restricts the development of the industry. Therefore, the storage and preservation technology of Huangguan pear fruit has been widely concerned by people in the indus...

Problems solved by technology

[0003] The existing Huangguan pear fresh-keeping method is generally low-temperature refrigeration, mainly adopting the mode of gradual cooling, but when the cooling time is too long and the cooling speed is too fast, the fruit is prone to black hearts, softening or brown spots, which makes the products greatly reduced value

Other treatment methods such as plastic film packaging, hormones (such as 1-methylcyclopropene), coating treatment, etc., although they can effectively prolong the storage time of fruits, but the plastic film is not easy to degrade, and there are harmful substances in chemical preservatives such as hormones. It is easy to cause harm to human body and environment
