Abstract
The invention provides a grape film preservative. The preservative comprises the following components: chitosan, chitin, ascorbic acid and an aqueous solution of para-aminobenzoic acid. The invention has the characteristics that: the preservative can inhibit pathogenic bacteria, reduce rotting rate and keep sensory quality, has a long-term and uniform effect and the like.
Description
Technical field
The invention belongs to the food preservative technology field, provide a kind of high-quality lasting grape coating antistaling agent.
Technical background
Along with development of science and technology, the raising gradually of people's living standard, people strengthen the demand of the fruit that the different regions Various Seasonal is produced gradually, but the perishable fruit freshness preserving phase such as grape is short, is difficult for storing.And the fresh-keeping and storing of the fruit that people store difficulties such as grapes has proposed increasingly high requirement with transportation.To this, many inventors provide a lot of effectively method for making and the usages of long-acting preservative.
Like Chinese patent " CN1359627 antistaling agent for grape " a kind of antistaling agent of processing with certain proportion with potassium metabisulfite or sodium pyrosulfite and gelatin or silica gel, stearic acid, calcium stearate is provided.Chinese patent " CN101215809 combined type grape fresh-keeping paper and preparation method thereof " provides a kind of combined type grape fresh-keeping paper and preparation method thereof.This paper is formed by shape, upper, middle and lower-ranking substrate combination of the same size, its at the middle and upper levels B district spray be furnished with citric acid solution; The middle level is a sealed polyethylene plastic; Lower floor 1 district is coated with and is stained with the omnidistance antistaling agent that discharges, and 2 districts are coated with to be stained with and delay the slowly-releasing antistaling agent, and 3 districts are pasted with quick-acting antistaling agents.Chinese patent " preparation method of CN101467553 fruit antistaling agent " provides a kind of to be mixed Jiao's industry potassium sulfate with stearic acid, after heating, be added into gelatin or starch, gets the method for solid preservative after the cooling.
Prior art is having certain progress aspect normal temperature or preservation by low temperature, long acting fresh-keeping, the transportation fresh-retaining really.But also come with some shortcomings, be mainly: 1, the release period of antistaling agent or preservative film is shorter, and preservation is inhomogeneous, is difficult in order to be effective; 2, antistaling agent or preservative film method for making complicacy are cumbersome; 3, it is higher to manufacture cost, and raw material sources are narrow; 4, raw materials used have a little harm to human body.
Summary of the invention
Based on above understanding, the purpose of this invention is to provide a kind of normal temperature antistaling agent for grape of filming, this antistaling agent suppresses pathogen, reduces rotting rate, keeps organoleptic quality, and effect is even for a long time.
For achieving the above object, the present invention is based on following technical scheme: 1, add chitin, have clarification, purify, eliminate the unusual smell, stop effect such as ascorbic oxidative degradation; 2, material source is wide, and is with low cost; 3, do not discharge any gas that is pernicious to people, can be for a long time and grape mix and put together and do not produce any negative interaction.
The mass fraction of each component does among the present invention
Shitosan 10～20%
Chitin 10～20%
Ascorbic acid 2～8%
The p-aminobenzoic acid aqueous solution (2%) 60～80%
The specific embodiment
Below be its a kind of embodiment, each constituent mass umber does
Shitosan 10%
Chitin 10%
Ascorbic acid 5%
The p-aminobenzoic acid aqueous solution (2%) 75%
Manufacturing approach is: earlier shitosan, p-aminobenzoic acid solution are evenly mixed in 70 ℃, again institute's thing and chitin, ascorbic acid are mixed in 65 ℃, after stir, be cooled to normal temperature and promptly get.
Claims (2)
