Abstract
The invention relates to grape preservative paper and a manufacturing method thereof. The grape preservative paper is characterized by comprising the following main raw materials in percentage by mass: 0.5-5% of polyvinyl alcohol, 0.5-10% of rosmarinic acid, 1-20% of chitosan, 40-60% of sodium pyrosulfite and 10-30% of water. The invention further discloses a method for manufacturing the grape preservative paper. The grape preservative paper has a high-efficiency preservation effect, prolongs the storage period and shelf life of grape and is low in cost.
Description
Technical field
The present invention relates to a kind of antistaling paper for grapes and preparation method thereof, belong to the food fresh keeping field of engineering technology.
Background technology
The Vitis berry fruits, extensively plant in China, and take wine brewing as main except some areas, and all the other most grapes are for eating raw.But, because grape soft and succulency, moisture content are high, by germ, invaded, easily mouldy rotting, lose commodity value.Therefore the preservation technique of grape is for the grape postharvest storage of eating raw, extremely important.The chemical agent preservation technique is one of main method of current preservation and freshness, but is based on the factor consideration of environment and health, and its security of applying on food is extensively queried.The physical fresh-keeping technology is paid close attention to widely.Tin foil is that the anti-corrosive fresh-keeping composition is coated on wrapping paper, forms ventilative a, water conservation, antibacterial subenvironment, thereby plays fresh-keeping effect, extends storage and transportation of grapes freshness date and shelf life.
Rosmarinic acid be present in wild marjoram, rosemary, Xue MingRosma rinus officinalis, a kind of polyphenol in the plants such as lemon balm, Salvia japonica and marjoram, there is non-oxidizability preferably and to the inhibition kill activity of some mushroom, therefore also for food antiseptic.Shitosan is as one of antistaling agent raw material commonly used, and its action effect also obtains more approval.By literature search, not yet find take that polyvinyl alcohol, Rosmarinic acid, shitosan, sodium pyrosulfite prepare tin foil as main component, for extending the research report of Grape During Storage phase and shelf life.
Summary of the invention
The present invention is directed to the deficiency of existing preservation technique, a kind of antistaling paper for grapes and preparation method thereof is provided, can effectively extend Grape During Storage phase and shelf life, improve commodity value and economic benefit, there are good Application and Development potentiality.
The present invention completes by following technical proposal: a kind of antistaling paper for grapes and preparation method thereof, it is characterized in that, its main raw material mass ratio is: polyvinyl alcohol 0.5-5%, Rosmarinic acid 0.5-10%, shitosan 1-20%, sodium pyrosulfite 40-60%, water 10-30%.The preparation method of tin foil contains following steps: than choosing raw material, respectively solid material is placed in to pulverizer by metering, is crushed to 100 order powder, and proceeds to successively mixer, add water, making beating at a high speed, to being even viscous liquid.Get above-mentioned thick liquid and evenly be applied on paper, coating amount is opened paper 5 ~ 8 grams by every 8, is coated with the post-drying packing and uses.Under normal temperature or refrigerated condition, with the present invention 8, open 2 ~ 5 of tin foils, can pack and process 10 kilograms of grapes.
The invention has the beneficial effects as follows: antistaling paper for grapes provided by the present invention, grape is had to fresh-keeping effect preferably, can extend storage period and shelf life.And materials safety used is high, preparation technology and using method are simple, have good development prospect.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, the present invention describes with following specific embodiment, but the present invention is limited to absolutely not these examples.
Embodiment 1: weighing polyvinyl alcohol 10 grams, Rosmarinic acid 10 grams, shitosan 20 grams, sodium pyrosulfite 100 grams, water 40 grams.Respectively solid material is placed in to pulverizer, is crushed to 100 order powder, and proceeds to successively mixer, add water, making beating at a high speed, to being even viscous liquid.Get above-mentioned thick liquid and evenly be applied on paper, coating amount is opened paper 5 ~ 8 grams by every 8, is coated with the post-drying packing and uses.Result of the test shows: in the transportation and sales process of circulation, and under 20-30 ℃ freshness-retained 8 days, under 5-10 ℃ freshness-retained 16 days; In 0 ℃ of freezer, preserve, freshness-retained 90 days, good fruit rate was all more than 90%.
Claims (2)
1. antistaling paper for grapes and preparation method thereof, is characterized in that, its main raw material mass ratio is: polyvinyl alcohol 0.5-5%, Rosmarinic acid 0.5-10%, shitosan 1-20%, sodium pyrosulfite 40-60%, water 10-30%.
2. a kind of antistaling paper for grapes according to claim 1 and preparation method thereof, it is characterized in that, its preparation method contains following steps: choose raw material by above-mentioned metering ratio, respectively solid material is placed in to pulverizer, be crushed to 100 order powder, and proceed to successively mixer, add water, at a high speed making beating, to being even viscous liquid, get above-mentioned thick liquid and evenly be applied on paper, coating amount is opened paper 5 ~ 8 grams by every 8, is coated with the post-drying packing and uses.
