Abstract
The invention relates to an litchi preservative which is characterized by mainly comprising the following components in percentage by mass: 0.1-5% of glucose, 0.1-10% of rosmarinic acid, 0.1-10% of sodium alginate, 5-15% of ascorbic acid, 1-20% of chitosan and the balance of water. The preparation method comprises the following steps: dissolving rosmarinic acid and ascorbic acid in water, sequentially adding glucose, sodium alginate and chitosan, supplementing the balance of water, and sufficiently stirring uniformly. After the litchi fruit is immersed in the preservative or coated with the preservative for 10-30 minutes and dried in air, the preservative has favorable preservation effect on the litchi, prolongs the storage life and shelf life of the litchi, and has favorable 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.
Rosmarinic acid is a kind of polyphenol be present in the plants such as wild marjoram, rosemary, Xue MingRosma rinus officinalis, lemon balm, Salvia japonica and marjoram, has non-oxidizability preferably and to the inhibition kill activity of some mushroom, therefore also for food antiseptic.Sodium alginate 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 glucose, Rosmarinic acid, sodium alginate, 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: glucose 0.1-5%, Rosmarinic acid 0.1-10%, sodium alginate 0.1-10%, ascorbic acid 5-15%, shitosan 1-20%, 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 Rosmarinic acid and ascorbic acid is soluble in water, then adds successively glucose, sodium alginate 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: glucose 1 gram, Rosmarinic acid 2 grams, sodium alginate 80 grams, ascorbic acid 60 grams, shitosan 150 grams, first that Rosmarinic acid and ascorbic acid is soluble in water, add successively again glucose, sodium alginate and shitosan, supply surplus moisture, to the solution gross mass be 1000 grams, stir.Soak or coating processing litchi fruits 15 min with this antistaling agent, dry.Through the method, fresh-keeping lichee is placed in humidity 80 ~ 90%, under 20 ~ 30 ℃ of conditions of temperature, preserves after 10 days, good fruit rate > 85%; Be placed in humidity 80 ~ 90%, preserve under 10 ~ 15 ℃ of conditions of temperature after 30 days, good fruit rate 75%.
Claims (3)
