Abstract

The invention relates to a method for preparing olive powder, belonging to the technical field of food processing. A production process of the method comprises the following steps of: selecting fresh high-quality olive fruits; cleaning; squeezing olive juice; filtering centrifugally; adding a certain proportion of dextrin into filtered juice; and performing spray drying to obtain the olive powder. The dextrin can be uniformly mixed with the olive powder obtained by adopting the method, so that the taste of the olive powder is improved, and deep processing on the olive powder is convenient; and meanwhile, due to the adoption of a spray drying process, the nutritional components in olive can be fully kept.

Description

A kind of preparation method of emblica powder

Technical field

The invention belongs to food processing technology field, more relate to a kind of preparation method of emblica powder.

Background technology

Olive has another name called emblic, originates in India, Pakistan, Sri Lanka, Malaysia, Philippine, Thailand and China.Main product is in southern area at home, and is wherein maximum with Yunnan output.The nutrient composition content of olive is very abundant, except that being rich in vitamin C, several amino acids and trace element, also contains carrotene, pectin, alkaloid, nicotinic acid, riboflavin, organic acid and tannin etc.Vitamin C can be blocked strong carcinogenic substance N-nitroso compound synthesizing in animal and human's body in the olive fruit juice, and its blocking-up rate reaches more than 90%, than the high 3-5 of vitamin C times with concentration.In addition, the successive dynasties physician thinks that olive has good results such as the gorget that promotes the production of body fluid to quench thirst, hawks, moistening lung step-down, resolving phlegm and removing blood stasis.And new fresh olive storage life is short, and taste is too sour and astringent.Application number is that 200710009011.6 prescription is too complicated, has lost the original local flavor of olive.

Summary of the invention

The object of the present invention is to provide a kind of preparation method of emblica powder, in the olive juice that squeezes, add dextrin, and then spray-drying, thereby making the emblica powder delicate mouthfeel that obtains, the deep processing of being more convenient for can effectively keep the nutritional labeling in the olive simultaneously.

Major technique feature of the present invention is thereby that the new fresh olive juice that is dissolved with the certain proportion dextrin is carried out the method that spray-drying makes emblica powder.

Production technology of the present invention is: select to add dextrin → spray-drying → emblica powder in the juice of fresh quality olive fruit → clean → squeeze olive juice → centrifugal filtration preferably → after filtration.

The concrete preparation method of emblica powder of the present invention is as follows:

Select materials, select the olive fruit fresh, intact, that maturity is suitable; Clean, with clear water flushing olive fruit raw material; Squeeze the juice, cleaned raw material is poured into squeezed olive juice in the juice extractor; Centrifugal filtration obtained olive original juice in centrifugal filtration 2-20 minute with the olive juice that squeezes in the centrifuge of 1000r/min-6000r/min; The adding of dextrin in the olive juice adds the dextrin that accounts for the heavy 0.0001%-80% of olive juice in the centrifugal olive original juice that obtains; Spray-drying, treat that dextrin fully dissolves after, the spray-dried tower of olive juice dextrin mixed liquor is carried out instantaneous vacuum spray drying, 180～220 ℃ of EATs, 60～100 ℃ of leaving air temps, vacuum is-700～-900Pa, obtain emblica powder.

The preparation method of emblica powder of the present invention also can be:

Select materials, select the olive fruit fresh, intact, that maturity is suitable; Clean, with clear water flushing olive fruit raw material; Squeeze the juice, cleaned raw material is poured in the juice extractor, add a certain proportion of drinking water, squeeze olive juice; Centrifugal filtration, with the olive juice that squeezes in the centrifuge of 1000r/min-6000r/min centrifugal filtration 2-20 minute olive juice; The adding of dextrin in the olive juice adds dextrin in the centrifugal olive juice that obtains, the addition of dextrin is that equivalent weight olive fruit can be squeezed the heavy 0.0001%-80% of olive original juice; Spray-drying, treat that dextrin fully dissolves after, the spray-dried tower of olive juice dextrin mixed liquor is carried out instantaneous vacuum spray drying, 180～220 ℃ of EATs, 60～100 ℃ of leaving air temps, vacuum is-700～-900Pa, obtain emblica powder.

Among the present invention, dissolving in dextrin earlier, sneak into dextrin in the emblica powder that makes uniformly and make, for sufficient preparation is carried out in deep processing through in the olive juice of centrifugal filtration, olive juice dextrin mixed liquor adopts spray drying technology to obtain emblica powder, can fully keep the nutritional labeling in the olive.

Embodiment 1

After selecting suitable olive fruit and cleaning, olive really squeezed the juice and centrifugal filtration 8 minutes in the centrifuge of 2000r/min, in the olive original juice that obtains, add 5% dextrin by weight, after treating that dextrin fully dissolves, through the vaccum spray drying tower drying, the EAT of spray drying tower is about 200 ℃ with olive juice dextrin mixed liquor, and leaving air temp is about 75 ℃, vacuum is-750Pa about, obtain emblica powder.

Embodiment 2

After selecting suitable olive fruit and cleaning, really pour into olive in the juice extractor, and add a certain proportion of drinking water, squeeze the juice and centrifugal filtration 3 minutes in the centrifuge of 4000r/min, in the olive juice that obtains, add dextrin, the addition of dextrin be equivalent weight olive fruit can squeeze olive original juice heavy 30%, after treating that dextrin fully dissolves, with olive juice dextrin mixed liquor through the vaccum spray drying tower drying, the EAT of spray drying tower is about 210 ℃, leaving air temp is about 80 ℃, vacuum is-780Pa about, obtain emblica powder.
