High-efficient denucleation method of preserving phyllanthus embica Linn. active functional ingredients

Abstract

The invention discloses a high-efficient denucleation method of preserving phyllanthus embica Linn. functional ingredients. The high-efficient denucleation method of preserving the phyllanthus embicaLinn. active functional ingredients includes the steps of pretreatment, cryopreservation, defrosting and denucleation, specifically including picking and choosing, removing impurities from and washingfresh phyllanthus embica Linn. fruit for later use, cooling the fresh phyllanthus embica Linn. fruit at a rate of 15-25 DEG C / min to 30-50 DEG C, and performing cryopreservation at a temperature of 30-50 DEG C, taking out the fresh phyllanthus embica Linn. fruit subjected to cryopreservation, and rinsing and defrosting the fresh phyllanthus embica Linn. fruit with cyclic flowing water at a temperature of 5-10 DEG C, and denucleating the phyllanthus embica Linn. to obtain phyllanthus embica Linn. pulp. A specific freeze thawing temperature is utilized, and a specific pretreatment and freeze thawing method are combined, so that time consumption is remarkably reduced, denucleating efficiency is improved, the removing capability of the contents of polyphenol and flavone and free radicals of ABTS and DPPH from the phyllanthus embica Linn. Pulp is not only preserved but also slightly improved.

Description

technical field [0001] The invention belongs to the technical field of food deep processing, and in particular relates to a high-efficiency denucleation method capable of retaining functional components and activities of emblica. Background technique [0002] Amla ( Phyllanthus emblica Linn.) is a plant of the Euphorbiaceae Phyllanthus genus, tree, up to 23 meters, diameter 50 cm; bark light brown; branches with vertical stripes, covered with yellow-brown pubescence. Leaf blade papery to leathery, two rows, linear oblong, 8-20 mm long, 2-6 mm wide, apex truncated or obtuse, with acute tip or slightly concave, base shallow cordate and slightly slanted Oblique, green above, light green below, reddish or light brown after drying, slightly dorsally rolled margins; 4-7 lateral veins on each side; petiole 0.3-0.7 mm long; stipules triangular, 0.8-1.5 mm long, brownish red , with eyelashes on the edge. The flowering period is from April to June, and the fruiting period is from ...

AI Technical Summary

Problems solved by technology

However, at present, the processing technology of Amla emblica industry is relatively backward. In the process of industrial production, the whole fruit of Amla emblica is usually broken, and the pulp and core are processed.

Fatty acids, fibers and other components in the fruit core enter the pulp, affecting the utilization of functional components in the pulp such as polyphenols and flavonoids, reducing the output and quality of pulp products; moreover, the crushing of fruit cores consumes a lot of energy and increases production costs , the utilization rate of by-products such as pomace and fruit stones is low
