The specific embodiment
The preferred embodiment of the present invention will be described in more detail below.
The present invention relates to a kind of beverage made of fruits or vegetables composition, gross weight based on described composition, comprise that the colourity of the vitamin C of the oligosaccharides of the fig concentrate of 1~5wt%, the fructose of 5~15wt%, 0.5~5wt%, the citric acid of 0.01~0.2wt%, 0.01~0.1wt%, the SY-RED pigment of 0.005~0.05wt%, 0.005~0.05wt% is mixed RS-L pigment, the fig flavor of 0.005~0.15wt% and purifying waste water of 74.45~93.465wt%.
In the beverage made of fruits or vegetables composition, above-mentioned fig concentrate can prepare with the leaf of fig tree, branch, fruit etc., especially advantageously the branch of fig and fruit.The fig leaf is owing to the taste of distinctive bitter taste and extreme difference is difficult to use in the beverage.Yet fig fruit has high sugared content and unique taste and fragrance, and comprises alkaloid, saponin, natural gum, rosin and possess the ficin of highly active proteolytic enzyme, advantageously so that fig fruit can be used as beverage.And the branch of fig comprises compositions such as psoralen, Buddha's hand lactones, guaiazulene, can further be included in the beverage made of fruits or vegetables composition.
In the beverage made of fruits or vegetables composition, fig preferably uses with the concentrate form with high sugared content, to keep its distinctive fragrance, taste and sweet taste.
Described fig concentrate can prepare by following steps: a) squeezing fig; B) based on the fig of 100 weight portions, add purifying waste water of 20~40 weight portions, then 80~90 ℃ of heating 8~12 minutes and be cooled to 50~55 ℃, obtain thus the fig solution that cools off; C) based on the fig solution of 100 weight portions, add pectase and the polysaccharase (beta amylase) of 0.1~0.2 weight portion in the fig solution of cooling, then solution was placed 2~6 hours; D) at 90~95 ℃ with above-mentioned enzymatic inactivation 8~12 minutes; And e) under reduced pressure mentioned solution is cooled off, filters and concentrate, 90~95 ℃ of sterilizations 10~20 minutes, be cooled to 60~70 ℃ subsequently, and encapsulation.
In the preparation of fig concentrate, step a) in the squeezing fig can use methods known in the art to carry out, such as disintegrating machine, mixer, fruit juice mixer etc.Because fig may overstrike in expressing process, can use the method for this brown stain of any prevention, but the invention is not restricted to this.
In the preparation of fig concentrate, step a) in the squeezing fig by step b) and step c) extract.At step b) in, the fig of squeezing is heated, and this is backward wherein to add pectase and polysaccharase (beta amylase) so that fig decomposes fully.
Particularly, step b) purify waste water by in the fig of squeezing, adding, then in 80~90 ℃ it is heated to obtain fig solution and carry out.Based on the fig of 100 weight portions, add 20~40 weight portions, then purifying waste water of preferred 30 weight portions heated 8~12 minutes, preferred 10 minutes.If the amount of purifying waste water surpasses 40 weight portions, in concentration step subsequently, need long-time.On the contrary, if the amount of purifying waste water is less than 20 weight portions, fig may be damaged in the process of extraction.
And if heat being lower than under 80 ℃ the temperature with the fig of the combination of purifying waste water, active ingredient can not extract from fig fully.On the contrary, if heating-up temperature is higher than 90 ℃, mentioned component may lose efficacy.
Subsequently, fig solution is cooled to 50~55 ℃.This temperature can keep following step c) in the activity of pectase and polysaccharase (beta amylase).
Carry out step c) remove when the typical case of the beverage that uses fruit prepares because the pectin that exists in the fruit, polysaccharide, carbohydrate and the deposit that in supply process, produces, the deposit that produces in supply process can cause the consumer to avoid selecting beverage, has reduced the satisfaction of product undesirablely.Therefore, above-mentioned colloid etc. preferably must use pectase and polysaccharase (beta amylase) to decompose.
Based on the fig solution of 100 weight portions, the amount of pectase and polysaccharase (beta amylase) is preferably 0.1~0.2 weight portion.And fig solution can be processed preferred 4 hours 2~6 hours with pectase and polysaccharase (beta amylase).If the amount of these enzymes is less than 0.1 weight portion, the colloid in the fig solution, polysaccharide etc. can not fully decompose, and can stay.On the contrary, if the amount of these enzymes surpasses 0.2 weight portion, can have a negative impact to the distinctive smell of fig, reduce Preference undesirablely.Therefore, these enzymes preferably add with above-mentioned amount.
For making steps d) in enzyme deactivation, temperature preferably rises to 90~95 ℃.And heated 8~12 minutes, and preferably heated 10 minutes, so that the enzyme complete deactivation, but the invention is not restricted to this.
