Abstract

The invention provides a plum-extract making method, using green plum as raw material, removing plum-pit, squeezing to get plum juice, filtering the plum juice, then sterilizing and primarily distilling at 80-120 deg.C, and then concentrating in vacuum-concentrator until the soluble solid up to above 60% to get the plum extract. It effectively holds the plum's natural flavor, nutritious components and faint scent.

Description

The plum extract making method

Technical field

The present invention relates to a kind of fruit plum extract making method.

Background technology

The fruit plum is nutritious, contains the plurality kinds of health care composition, finds to contain in the fruit plum vitamin that needed by human body wants, mineral nutrition, protein, organic acid etc. in the modern medicine study; Have and purify the blood, strong liver, whole intestines, eliminate tired, anti-ageing, sterilizing function, have anticancer, improve cardiovascular function, promote medical values such as digestion, particularly containing plurality kinds of health care compositions such as several amino acids, Flavonoid substances, free sugar, carbohydrate, vitamin, is low sugar, low-fat basic food.Fatty liver, artery sclerosis, hypertension, diabetes, coronary heart disease etc. there are certain prevention and therapeutic action.But because of fresh fruit is difficult to storage, and it is few to eat consumption raw, generally is processed into behind the various prune products edible.The fruit plum is mainly conventional articles such as plum embryo goods, plum vinegar, plum wine, Greengage beverage, plum jelly, carving plum, crisp plum at present, these goods one are to the outward appearance of fruit plum, fruit shape specification, single fruit weight, maturity etc. are all had strict demand, the fruit plum fails to utilize fully, the 2nd, effective ingredient loss or the destructiveness of process fruit plum are bigger, three additives that are to use are more, influence edible safety or reduced natural flavour mountaineous.

Summary of the invention

The purpose of this invention is to provide a kind of that do not contain additive and can keep article process---the plum extract making method of fruit plum effective ingredient and natural flavour mountaineous fruit plum.

The present invention is achieved in that

With the green plum is raw material, removes plum nuclear, is squeezed the juice after the squeezing, and the plum juice after filtering of squeezing the juice is sterilized under 80～120 ℃ temperature and just carried, and concentrates in vacuum decker then, be concentrated into soluble solid reach 60% when above plum medicinal extract.

Technological process of the present invention is:

Raw material → cleaning → stoning → squeezing → filtration → sterilization, just carry →

Vacuum concentrate → is bottled → is sealed → sterilization → cooling → finished product.

Obtain after the squeezing squeezing the juice and filter in 80～120 purpose screens, the plum juice after the filtration of squeezing the juice is sterilized under 80～20 ℃ temperature and is just carried 0.5～2 hour.When vacuum concentrated in vacuum decker, vacuum was 60～120kPa, and is both economical reasonable when thickening temperature is 40～60 ℃.

Embodiment:

Fruit plum 20kg, stoning gets plum meat 14.5kg, get plum slag 5.1kg after the squeezing, the 9.4kg that squeezes the juice squeezes the juice and filters in 100 purpose screens, and the plum juice after the filtration is after sterilizing under the temperature about 95 ℃ and just carrying 1 hour, in vacuum decker, be 80kPa in vacuum, thickening temperature is 50 ℃ and heats concentratedly, through 50 minutes, obtains pitchy plum medicinal extract finished product 0.8kg.

Be to be raw material in the whole process of preparation of the present invention with the green plum, do not add any other material, effectively kept natural flavour mountaineous, nutrition and the faint scent of fruit plum, its contained mineral matter, organic acid, sugar all are better than the tradition fruit plum product of same place of production processing.Specific targets see the following form:

Plum medicinal extract analysis of components contrast table

It is easy that the present invention has technology, instant, every gram plum medicinal extract is equivalent to plum 20～40 grams, and long shelf-life, the outward appearance of fruit plum, shape, weight etc. all there is not strict requirement, but remaining plum slag addition plum sauce, prune, plum powder, plum mud etc., plum nuclear extracts japanese apricot seed oil and laetrile, has greatly improved the resource utilization of fruit plum.
