Description

A kind of apple, pears antistaling agent and using method thereof
Technical field
The present invention relates to fruit food preservative technology field, refer in particular to a kind of fruit antistaling agent for apple, pears and using method thereof.
Background technology
Apple and pears delicious flavour, nutritious, liked by people.But the harvest time of apple and pears is shorter, generally in summer and autumn, gather in the crops, after results, be transported to each city without apple and pears, the whole nation, or be in store, in the non-harvest time of apple and pears, meet popular eating requirements.Yet, at shelf during Long-term Cold Storage and after refrigeration, between the storage life, often there is pericarp browning in apple, pears, be casting skin or tiger fur phenomenon, had a strong impact on the exterior quality of fruit, nutrition and the edibility of apple, pears have not only been affected, also can affect numerous growers and operation sellers' enthusiasm, thus the development of restriction apple, pears industrial economy.Therefore, the storage and freshness-retaining technology of apple, pears is subject to insider's common concern.
Fresh apple after gathering, the physiological activity of pear and other fruits are vigorous, and the gases such as ethene that the carbon dioxide producing due to respiration and discharging in fruit After-ripening has catalytic action are all unfavorable for fruit storage.In addition, fresh fruit water content is high, if store improperly, very easily makes fruit dehydration wilt, or rots, thereby affect its exterior quality and nutritive value.
Existing fruit freshness preserving is mainly deepfreeze and hypoxemia storage, though the fresh-keeping effect of this storage mode is good, but need larger investment, and once apple, pears depart from such fresh-keeping environments (condition), be placed on the shelf of normal temperature and sell, after several hours, pericarp starts brown stain, and its commodity value is reduced greatly.Another kind of conventional fresh-keeping mode is to adopt plastic sheeting, and it all wraps up every fruit, allows it maintain respiration slowly.The shortcoming of this fresh-keeping mode is that the heat that respiration of fruits process produces is difficult for scattering and disappearing, and the time has been grown fruit and still can rot, and plastic sheeting is difficult for degraded, easily contaminated environment.Also having a kind of conventional fresh-keeping mode is that to adopt chemical preservative to carry out fruit fresh-keeping, as takes diphenylamines, ethoxyquinoline and 1-methyl cyclopropene (1-MCP) to process apple, pear and other fruits after plucking.Although chemical preservative has good fresh-keeping effect, but chemical treatment has the residual chemical contamination problem causing of harmful substances, also may there is the deficiency of peculiar smell and fruit after-ripening obstacle, a lot of synthetics confrontation healths have certain harm in addition, serious meeting makes people carcinogenic, and diphenylamines is processed disabled in some countries.Therefore, research and develop new fruit freshness preserving technology necessary.
Summary of the invention
The technical issues that need to address of the present invention are to provide and a kind ofly reduce moisture loss during refrigeration and normal temperature shelf life of apple and pears, reduce casting skin incidence, keep bright and clean fresh, the nuisanceless antistaling agent that taste of fruit is good of fruit face.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Apple, pears antistaling agent, comprise OPC, vitamin E, beeswax, food stage glycerine, water, and in every 1000ml antistaling agent, the content of each component is:
OPC 500~800 mg,
Vitamin E 30~50 mg,
Beeswax 50~100 mg,
Food stage glycerine 0.5~1.0 ml,
Water surplus.
Preferred version of the present invention is: apple, pears antistaling agent, and in every 1000ml antistaling agent, the content of each component is:
OPC 700 mg,
Vitamin E 40 mg,
Beeswax 80 mg,
Food stage glycerine 0.8 ml,
Water surplus.
The present invention also provides the using method of this antistaling agent: while using described antistaling agent, according to the content of each component, take each raw material, and OPC, vitamin E, beeswax, food stage glycerine are mixed, then add water preparation and mix; Then apple or pear fruit were soaked after 3~5 minutes in antistaling agent, dry, storage.
This antistaling agent is applicable to process before apple or pear fruit refrigeration, or after outbound, fruit is processed before moving into shelf; Antistaling agent needs matching while using.
Owing to having adopted technique scheme, the technological progress that the present invention obtains is as follows:
Adopt antistaling agent of the present invention to solve apple, pears during Long-term Cold Storage and the fruit dehydration wilting occurring, the problem of brown stain casting skin during shelf are put sale, be the problem that outward appearance freshness declines, antistaling agent of the present invention is a kind of non-harmful product.This antistaling agent raw material is easy to get, method for making is simple, with low cost, easy to operate while using, efficiently solve the problem that casting skin between refrigeration and normal temperature shelf storage life of apple, pears or tiger fur and dehydration are wilted, reach good fresh-keeping effect.
The OPC using in the present invention is a kind of natural, there is good antioxidant effect, be used in conjunction with vitamin E, effectively suppress the respiratory intensity of apple, pear and other fruits, the freshness that keeps fruit, the physiological metabolism of delayed fruit, the while has maintained the nutritional labeling of fruit preferably, and nontoxic non-stimulated.Beeswax and food stage glycerine are used in conjunction with, and make apple, pears after this antistaling agent of immersion is also air-dry, and fruit surface can form the film of layer of transparent, can strengthen its epidermis protective action, suitably stop up epidermis pore, suppress respiration, reduce nutrition loss, suppress moisture evaporation, effectively prevent pericarp shrinkage, wilting, suppressing microorganism invades, prevent putrid and deterioratedly, its effect is similar to individual packing, simple to operate, good refreshing effect, pollution-free.When keeping fruit good taste, make the appearance looks elegant of fruit beautiful, the shelf that greatly improved fruit are worth.
This antistaling agent using method is easy, and the fruit of the fresh-keeping apple of needs, pears is soaked after 3~5 minutes through antistaling agent, dries storage.Can before apple, pears refrigeration, process, or after outbound, fruit is processed before moving into shelf.
This antistaling agent is removed easily from fruit, only need be immersed in clear water and just can remove.And in this antistaling agent, the raw materials used food hygienic standard that all meets, nontoxic, can directly eat and needn't remove antistaling agent, even if do not have this antistaling agent to remove totally when edible, can not be detrimental to health yet.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is done further to describe in detail.
