Abstract

The invention relates to the technical field of external-controlled food preservation, in particularly relating to a functional preservative film for an areca-nut, which comprises the following components in parts by weight: 82-94% of polyolefin grain, 3-10% of dehydroacetic acid, 3-5% of fatty acid and 0-3% of essence spice. In the preparation method, the antiseptic medicines are added in a packaging film, thereby effectively reducing the addition amount of the preservative in the areca-nut, effectively avoiding the overproof and over-range utilization of potassium sorbate and utilization of non-food preservative substance for preservation in the areca-nut, effectively solving the problem of short quality guarantee period of the areca-nut packaged in a monolithic vacuumization mode, and simultaneously solving the current situation that the alcohol antistaling agent and deoxidier are difficult to act on the packaged areca-nut. The invention has good preservation effect and high safety, and can keep the original mouthfeel of the areca-nut.

Description

Technical field: [0001] The invention relates to the technical field of externally controlled fresh-keeping of food, in particular to the fresh-keeping of betel nuts, in particular to a functional fresh-keeping film for betel nuts and a preparation method thereof. Background technique: [0002] Betel nuts have gradually become a consumer fashion in China as a hobby snack. However, because betel nuts are basically hand-made in the processes of cutting, pitting, brine, adding pits, and packaging, secondary pollution is serious, often resulting in finished betel nuts. During the short-term storage process, a large number of molds or the total number of molds and bacterial colonies exceeded the standard. Among them, mold is the main dominant spoilage flora, and mold growth or the total number of mold exceeding the standard are the main deterioration phenomena. These deterioration phenomena lead to the loss of large quantities of betel nuts during processing and the unstable qua...
