CN103519298A - Method of improving anthocyanin content of blueberry juice and improving blueberry juicing rate - Google Patents

Abstract

The invention discloses a method of improving anthocyanin content of blueberry juice and improving a blueberry juicing rate. The method comprises the following steps of: pulping the crudely crushed fruit blueberries by a pulping machine after crushing fruit blueberries by a crusher, and then, extracting the blueberry juice obtained by pulping; grinding the blueberry fruit residues exhausted by pulping as well as blueberry fruit seeds and extracted pulped blueberry juice by a high-speed colloid mill, adding compound pectinase after grinding for carrying out enzymolysis, and carrying out high-speed separation after enzymolysis, and extracting blueberry clear juice rich in anthocyanin after separating. According to the method disclosed by the invention, pulping is matched with fruit skin and fruit seed grinding to carry out enzymolysis, so that the fruit skin, the fruit seeds, and the like can be secondarily extracted, thereby sufficiently improving juicing rate and extraction of active ingredients. Besides, juicing amount is plentiful and anthocyanin content of the fruit juice is high.

Description

A kind of anthocyanidin content that improves blueberry juice and improve the squeeze the juice method of rate of blueberry

Technical field

The present invention relates to fruit juice manufacture field, refer more particularly to a kind of anthocyanidin content that improves blueberry juice and improve the squeeze the juice method of rate of blueberry.

Background technology

The mode of squeezing the juice of all inspissated juices enterprise has difference, all according to the composition of fruit, as deciding, pulp, fruit juice amount, fruit seed amount, hardness etc. take which kind of mode of squeezing the juice, and more flexible, as blueberry, belong to berry type fruit, normal extracting methods is beater or squeezer, these two kinds of modes all can access very high crushing juice rate, and the pomace of discharge is more dry, still, pericarp is all used as residue treatment with fruit seed, does not well obtain second extraction and utilization.The application's making beating is carried out enzymolysis after coordinating pericarp and fruit seed to grind, and can carry out second extraction to pericarp, fruit seed etc., the raising of filling part the extraction of crushing juice rate and effective ingredient.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of and be of high nutritive value, improve the anthocyanidin content of blueberry juice and improve the squeeze the juice method of rate of blueberry.

The present invention realizes in the following way:

The anthocyanidin content of blueberry juice and improve the squeeze the juice method of rate of blueberry, is characterized in that: comprise the steps:

(1), fruit blueberry, by after disintegrating machine coarse crushing, is pulled an oar the full fruit blueberry after coarse crushing by beater entirely, then extracts the blueberry juice that making beating obtains;

(2) blueberry pomace of, making beating being discharged and blueberries seed grind through colloid mills together with extracting the blueberry juice of pulling an oar, after grinding, add compound pectinase to carry out enzymolysis, after enzymolysis, carry out high-speed separation, the separated rear clear juice of blueberry that is rich in anthocyanidin that extracts.

The invention has the advantages that: making beating is carried out enzymolysis after coordinating pericarp and fruit seed to grind, and can carry out second extraction to pericarp, fruit seed etc., the raising of filling part the extraction of crushing juice rate and effective ingredient; The amount of squeezing the juice is many, fruit juice anthocyanidin content is high, and full fruit crushing juice rate can reach more than 95%.

The specific embodiment

The specific embodiment of the invention is described in detail in detail:

The anthocyanidin content of blueberry juice and improve the squeeze the juice method of rate of blueberry, comprises the steps: that (1), full fruit blueberry are by after disintegrating machine coarse crushing, and the fineness of disintegrating machine is controlled at 3mm left and right; By beater, use the rotating speed of 800 rpms to pull an oar the full fruit blueberry after coarse crushing, then extract the blueberry juice that making beating obtains; (2), blueberry pomace that making beating is discharged and blueberries seed grind through colloid mills together with extracting the blueberry juice of making beating, the fineness of grinding is not less than 60 orders, grinds the institutional framework of destroying blueberry; After grinding, add compound pectinase to carry out enzymolysis, after enzymolysis, adopt horizontal separation separated with folded formula combine separated, horizontal separation, 2900 rpms of main motor speeds, push away 900 rpms of slag rotating speeds, folded formula centrifuge is selected the model of 5800 rpms of above separated rotating speeds of rotating speed, controls out juice pressure and carries out high-speed separation at 0.2MPa, the separated rear clear juice of blueberry that is rich in anthocyanidin that extracts.

Embodiment:

Cleaned full fruit blueberry 1000g is passed through after disintegrating machine coarse crushing, the fineness of disintegrating machine is controlled at 3mm left and right, by beater, use the rotating speed of 800 rpms to pull an oar the full fruit blueberry after coarse crushing, then extract the 850g blueberry juice that making beating obtains; The blueberry pomace that making beating is discharged and blueberries seed grind through colloid mills together with extracting the 850g blueberry juice of pulling an oar; After grinding, add 0.9g compound pectinase to carry out enzymolysis, after enzymolysis, carry out high-speed separation, the separated rear clear juice of blueberry that 970g is rich in anthocyanidin that extracts.

Claims (1)

1. improve the anthocyanidin content of blueberry juice and improve the squeeze the juice method of rate of blueberry, it is characterized in that: comprise the steps:

(1), fruit blueberry, by after disintegrating machine coarse crushing, is pulled an oar the full fruit blueberry after coarse crushing by beater entirely, then extracts the blueberry juice that making beating obtains;

(2) blueberry pomace of, making beating being discharged and blueberries seed grind through colloid mills together with extracting the blueberry juice of pulling an oar, after grinding, add compound pectinase to carry out enzymolysis, after enzymolysis, carry out high-speed separation, the separated rear clear juice of blueberry that is rich in anthocyanidin that extracts.
