Abstract
The invention relates to a litchi preservative. The litchi preservative is characterized by comprising the following main components in percentage by weight: 0.01-0.5% of tea saponin, 0.01-5% of chlorogenic acid, 0.1-10% of citric acid, 5-15% of ascorbic acid, 10-20% of chitosan and the balance of water. A preparation method comprises the following steps: firstly dissolving the chlorogenic acid and the ascorbic acid in water, further sequentially adding the tea saponin, the citric acid and the chitosan, complementing the remaining water and fully and uniformly stirring. By using the preservative to soak or coat litchi fruits for 10-30 minutes, the preservative has a better preservative effect against litchi after airing, can prolong the storage period and the shelf life and has good application prospects.
Description
Technical field
The present invention relates to a kind of antistaling agent for litchi, belong to the Food Engineering Development field.
Background technology
Lichee originates in SOUTHERN CHINA, is one of the southern part of the country four large fruits, is also the pillar industry of some areas, huge to driving the increasing peasant income effect of getting rich.But litchi fruits is not anti-stores transportation, so made extensive work around the fresh-keeping of lichee and storage research in the industry, the biologic product exploitation antistaling agent of application safety is a very important content wherein, significant to the development of lichee industry.
Tea Saponin has another name called TS, has haemolysis and ichthyotoxin, pest-resistant bactericidal action, the effect of impervious anti-inflammatory, Promoting plant growth.In addition, Tea Saponin or well surfactant.Chlorogenic acid is a kind of phenylpropanoids that plant produces through shikimic acid pathway in the aerobic respiration process, there is non-oxidizability preferably and to the inhibition kill activity of some mushroom, therefore, chlorogenic acid is used to the fresh-keeping of fruit juice, can effectively prevent the putrid and deteriorated of drink and food.Citric acid is a kind of natural polysaccharide, has the required stability of pharmaceutical preparation auxiliary material, dissolubility, viscosity and security, is the common food additive.Ascorbic acid is a kind of water soluble vitamin, rich content in fruits and vegetables.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 Tea Saponin, chlorogenic acid, citric acid, ascorbic acid, shitosan prepare antistaling agent as main component, for extending the research report of lychee storage phase and shelf life.
Summary of the invention
The present invention is directed to the deficiency of existing antistaling agent technology, a kind of antistaling agent for litchi is provided, can effectively extend lychee storage phase and shelf life, improve commodity value and economic benefit, there are good Application and Development potentiality.Simultaneously, the present invention also provides a kind of and uses above-mentioned antistaling agent lichee to be carried out to the method for Preservation Treatment.
The present invention completes by following technical proposal: a kind of antistaling agent for litchi, it is characterized in that, its main component mass ratio is: Tea Saponin 0.01-0.5%, chlorogenic acid 0.01-5%, citric acid 0.1-10%, ascorbic acid 5-15%, shitosan 10-20%, all the other are water.The present invention also provides preparation and the using method thereof of antistaling agent for litchi, it is characterized in that, first that chlorogenic acid and ascorbic acid is soluble in water, then adds successively Tea Saponin, citric acid and shitosan, supplies surplus moisture, stirs.Soak or litchi fruits 10 ~ 30min is processed in coating with this antistaling agent, dry and rear lichee is had to fresh-keeping effect preferably, extend storage period and shelf life.
The invention has the beneficial effects as follows: antistaling agent for litchi provided by the present invention, lichee 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: Tea Saponin 5 grams, chlorogenic acid 2 grams, citric acid 100 grams, ascorbic acid 100 grams, shitosan 120 grams, first that chlorogenic acid and ascorbic acid is soluble in water, add successively again Tea Saponin, citric acid and shitosan, supply surplus moisture, to the solution gross mass be 1000 grams, stir.Soak or coating processing litchi fruits 10 ~ 15 min with this antistaling agent, dry.Through the method, fresh-keeping lichee is placed in humidity 75 ~ 90%, under 20 ~ 30 ℃ of conditions of temperature, preserves after 10 days, good fruit rate > 90.3%; Be placed in humidity 80 ~ 90%, preserve under 10 ~ 15 ℃ of conditions of temperature after 40 days, good fruit rate 75.6%.
Claims (3)
