Description

With the watermelon seed melon method of producing original juice health beverage particularly

The present invention relates to a kind ofly with the watermelon seed melon method of producing high-quality juice health drink particularly, juice beverage is clarified through enzymatic reaction, filters, and makes through lactobacillus-fermented again.

With the fruit of plant particularly melon and fruit make juice beverage and be of long duration, formed many methods.The known process of producing is: removes the nuclear and the skin of fruit, makes slurries, extract Normal juice, and refining Normal juice, it is anticorrosion to sterilize etc.In order to obtain high yield and high-quality Normal juice from fruit, it is very crucial that several steps is arranged in the above-mentioned technology, extracts Normal juice from the slurries of making that is:; The clarifying treatment of Normal juice; Handle with the sterilization anti-corrosive fresh-keeping of Normal juice.When the method that adopts machinery is separated Normal juice from slurries, can use decant-centrifugal separator or filter etc.The Normal juice that is separated to will be made further clarifying treatment, adopts methods such as ultrafiltration usually.Above-mentioned separation Normal juice and Normal juice processing procedure, process complexity not only, and influence the quality of Normal juice.

CN88101120 discloses a kind of processed fruit and method for vegetable, and to overcome the shortcoming of prior art, this method can obtain the Normal juice of higher quality and guarantee higher productive rate when reduce expense.The clarification of the Normal juice of this patent is refining to be realized with membrane filtration in a suitable manner.But, before filtration, the preparation more complicated of slurries, this patent proposes slurries with fruit such degree that only liquefies, promptly form a kind of aqueous-viscous fruit sauce with the coarse composition that can further liquefy and stick with paste, subsequently, this jam paste is sent into a squeezer and is produced Normal juice.

Need here be pointed out that, the above-mentioned method of from fruit, producing Normal juice, and be unwell to from the moisture fruit of height, watermelon etc. for example, extract Normal juice,, can select more simple and easy to do method on the contrary because high moisture fruit is difficult to make the desired slurries of above-mentioned patent.More reasonable from considering economically like this.

CN87106579 discloses a kind of preparation method of watermelon juice, and this patent prepares watermelon juice with the method for heating, should go though this method is easy, and the problem of thereupon bringing is the decline of Normal juice quality, and this patent is not considered the refining problem of melon juice.

The seed melon has another name called a kind of watermelon, is one of watermelon very special kinds, abounds with in NORTHWEST CHINA all provinces, particularly Gansu.For a long time, it is not for Shiqi meat that people plant it, but in order to get its son, its black melon seeds is famous " Lanzhou sheet ".And its skin, melon meat be as hazardous waste, and this has not only caused great waste, has also caused environmental problem.

Seed melon melon juice is distinguished the flavor of sweet cold in nature, contains trace elements such as abundant vitamin, carotene, several amino acids, glucose and Ca, P, Fe.Because the sugar content of seed melon juice is lower, so the little acid of mouthfeel is with sweet.Seed melon juice is not only nutritious, and health care and medical value are higher.The locals commonly used it as cough-relieving, control asthma, aid digestion etc. tonic.In addition, the delicate fragrance local flavor of melon juice is also very popular.In order to utilize this valuable resource, people are processed into tinned food to melon meat, perhaps attempt to make into Normal juice material by the emperor himself, but because processing method is improper, manufactured goods lost the seed melon exclusive local flavor and its health care and medical value, also can produce a kind of undesirable peculiar smell sometimes.

With the melon juice muddiness that technique known is produced, be because of containing due to the pectin, and be difficult for removing with general filtration and centrifugal method; In addition, the not easy-to-use traditional high-temperature boiling processing and refining of watermelon Normal juice, otherwise not only the nutrition of melon juice will be destroyed, and can produce undesirable peculiar smell, lose the distinctive local flavor of Normal juice.Seed melon juice for more special especially is noted that when producing and handling melon juice, and the temperature of melon juice is raised to more than 60 ℃.

The objective of the invention is to avoid the deficiency of above-mentioned prior art and provide a kind of with the watermelon seed melon method of producing original juice health beverage particularly, the present invention makes with extra care melon juice Normal juice with enzymatic reaction, handle Normal juice after refining with lactobacillus-fermented, to obtain high-quality juice beverage.

Purpose of the present invention can realize by following measure.

With the watermelon seed melon method of producing original juice health beverage particularly, through removing the melon seeds melon skin, broken defibrination, squeeze and filter, auxiliary material is added in the enzymatic reaction clarification, uses lactobacillus-fermented then.

Behind broken defibrination, squeeze and filter, obtain thick Normal juice, owing to contain pectin etc., normal juice is also relatively more muddy, uses the enzymatic reaction method in the thick Normal juice, can be with thick Normal juice clarification, after enzymatic reaction, some solids can be removed by the method for filtering.

The used enzyme of above-mentioned enzymatic reaction is a pectase, and the selection of pectase should be considered the character of handled Normal juice, as pH value etc.To watermelon seed melon particularly, preferably by what aspergillus niger produced, obviously used here enzyme should meet the food hygiene law and the health and quarantine standards of country to used pectase.

The effect of pectase is that pectin is decomposed, and pectase itself is not consumed in this reaction, and therefore, theoretically, the consumption of pectase is not limited by what of what and melon juice amount of pectin content in the melon juice can.But,,, and determine that the amount ranges of a pectase is useful according to what of contained pectin in the handled melon juice from economy and production efficiency.Enzymatic reaction condition is: the consumption of pectase is 0.05～2%(V/V, with respect to the amount of handling melon juice); Reaction temperature is 20～55 ℃; Reaction time is more than 2 hours.Take place if do not expect the result that produces, the time of reaction, for well, the consumption of enzyme was to be reaction temperature good and that selection is lower less with short.

After enzymatic reaction is finished, can obtain transparent melon juice.Follow the method for available fermentation and further handle melon juice, be i.e. inoculating lactic acid bacterium in melon juice.The melon juice of having inoculated lactic acid bacteria fermented 48 hours or longer under 20～50 ℃ of temperature.

Consider the mouthfeel and the local flavor of the material of admiring, can add suitable table sugar or essence, for example: sucrose, HFCS, honey etc. before fermentation or after the fermentation.Because seed melon sugar content is less, add suitable sugar, be favourable not only, and be necessary the mouthfeel of improving beverage to sweat.Auxiliary materials such as certain table sugar also can oneself be added when drinking by the consumer.

Adding an amount of antisepsis antistaling agent is favourable to the long term storage of any beverage, and the antistaling agent that the present invention selects for use has sorbic acid, benzoate etc. to be filled the material of being permitted by food hygiene law.The content of antistaling agent is subjected to strict restriction usually.

With the watermelon of the method for the present invention preparation original juice health beverage of seed melon particularly, not only do not destroy original nutrition of melon juice, but also sweet and sour palatability, unique flavor.Because seed melon juice is nutritious, the juice beverage of being produced has health care and medicinal dual quality.

Below by embodiment the present invention is further described below, makes the public understand the present invention better.
