Abstract
The invention relates to the technical field of refreshing, in particular to a fruit and vegetable coating antistaling agent, aiming at providing the fruit and vegetable coating antistaling agent which has low cost, green initiative and convenient application. The invention has the following technical scheme in particular: each liter of the fruit and vegetable coating antistaling agent contains 5-50g of pullulan sugar, 0.2-2g of preservatives, 1-20g of sorbitol, 5-50g of hydrophobizing agent, 1-30g of surfactant and the balance of solvent. The invention has the following advantages: the film-forming agent used in the invention contains less usage of the pullulan sugar, thus the cost is lowered; the hydrophobizing agent is added without the influence of condensed water. The preparation of the coating agent and the operation of the coating have simple steps and strong operability.
Description
Technical field
The present invention relates to the preservation technique field, be specially a kind of fruit and vegetable coating antistaling agent.
Background technology
Rotting after fresh fruit of vegetables is adopted is a global problem, and according to statistics, there is the fresh fruit of vegetables of 10-20% in developed country approximately because postharvest disease causes rotting, and developing country then reaches 40-50%.Because the backwardness of preservation technique, the fruit of Chinese annual output are directly wasted and loss late up to 38%.For solving the rotten problem of postharvest fruit and vegetable, prolong shelf life, the focus of research concentrates on the edible film-coating fresh-keeping method both at home and abroad at present.Edible film-coating is to be raw material with the edible natural material, the film that forms by the different molecular interphase interaction with porous network structure, and be covered in food surface by forms such as parcel, dipping, coating, sprinklings.It can suppress the exchange of fruits and vegetables gas, reduces respiration rate, reduces water evaporates, stop the oxidation of exposing to the sun when air, preventing the raised growth breeding of microorganism, thereby help keeping the nutritional labeling and the color of fruits and vegetables, is a kind of effective fruit and vegetable preserving method.
But also there are problems in most of coating antistaling agent, the one, contain the chemical composition that human body is existed harm, and do not meet the green safety requirement; The 2nd, the plastics water proofing property is poor, fruits and vegetables store and the process of circulation in owing to temperature fluctuation, condensed water often appears in the surface, plastics is soluble in water and lose protective effect.
Pulullan (Pullulan, also claim pullulan, the mould polysaccharide of short stalk, pullulan, pulullan polysaccharide or general poly-polysaccharide) as the appearance of the coating antistaling agent of main component, though part has solved above problem, but the consumption that also exists pulullan is big, cost is high, the problem of the film water proofing property difference of formation; There is complex treatment process again in the application of bi-component fruit and vegetable coating antistaling agent, the problem that operability is not strong.
Summary of the invention
The object of the invention is to provide a kind of with low cost, environmental protection, the easy fruit and vegetable coating antistaling agent of application.
Concrete technical scheme of the present invention is: a kind of fruit and vegetable coating antistaling agent, every liter of fruit and vegetable coating antistaling agent contains: 5-50g pulullan, 0.2-2g anticorrisive agent, 1-20g sorbierite, 5-50g water-repelling agent, 1-30g surfactant, all the other are solvent.
Described anticorrisive agent comprises natamycin and nisin, and every liter of fruit and vegetable coating antistaling agent contains 0.1-1g natamycin and 0.1-1g nisin.
Described water-repelling agent is one or more in food-grade shellac, atoleine, beeswax, polyvinyl acetate, oleic acid, the stearic acid.
Described surfactant is one or more in Arlacel-80, Arlacel-65, Arlacel-60, the Arlacel-20.
Described solvent is the mixture of second alcohol and water, and the volume ratio of second alcohol and water is 10:1-1:10, is 2.5-3.0 with one or more pH values of regulating solvent in acetate, citric acid or the lactic acid.Used solvent is acid, helps improving receiving its mycin solubility.
Beneficial effect of the present invention is:
1, the consumption of the used film forming agent pulullan of the present invention is less, reduces cost.Pulullan can form the transparent protective film with permselectivity at fruit and vegetable surfaces in concentration range of the present invention, whole fruits and vegetables are in low O
2With high CO
2Little controlled atmosphere environment of spontaneous adjusting, thus aerobic physiological and biochemical procedures such as respiration, ethene generation and the peroxidating of film fat suppressed, reach the purpose of preserving fruit and vegetable utilizing.
2, add water-repelling agent, be not subjected to the influence of condensed water.Water-soluble fine because of pulullan, because condensed water often appears in the temperature fluctuation fruit and vegetable surfaces, the film of formation is soluble in condensed water and loses protective effect, and the present invention adds the solubility that water-repelling agent reduces the pulullan film.
3, the plastics preparation and the operating procedure of filming are simple, workable.The present invention is applied to the Preservation Treatment of fruits and vegetables, and treatment process is easy: earlier fruits and vegetables are cleaned, fruits and vegetables are flooded in plastics 10-200 second again, or plastics evenly is sprayed at fruit and vegetable surfaces, dry moisture.
