Embodiment Construction

[0015] A production process for recovering bioflavonoids from pectin extraction ethanol waste liquid, the first step is to distill the pectin extraction waste liquid after pectin extraction;

[0016] In the second step, the liquid distilled in the previous step is adsorbed by an adsorption column filled with polyamide or polar macroporous resin as an adsorbent;

[0017] The third step, after being adsorbed, eluted with 30% ethanol solution, discarded the eluent, then eluted with 85% ethanol solution, and collected the eluent;

[0018] In the fourth step, the pH value of the eluent is adjusted to 4-5, the temperature is controlled at 70-80°C, and the time is 1-3 hours; the acid used in the fourth step to adjust the pH value is inorganic acid or dilute sulfuric acid;

[0019] The fifth step is to centrifuge the raw materials of the fourth step, discard the solid content, and keep the supernatant;

[0020] In the sixth step, flash drying produces a brown-yellow powder-like finis...

Abstract

The invention discloses a production technology for recovery of bioflavonoid from pectin extracted ethanol waste liquid. The technology includes: first step, distilling pectin extracted waste liquid after pectin extraction; second step, adsorbing the liquid subjected to distillation with an adsorption column filled with polyamide or polar macroporous resin as the adsorbent; third step, after adsorption, conducting elution with 30% ethanol, discarding the eluent, then performing elution with a 85% ethanol solution, and collecting the eluent; fourth step, adjusting the pH value of the eluent to 4-5, controlling the temperature at 70-80DEG C for 1-3h; fifth step, centrifuging the raw material of step 4, discarding solid, and retaining the supernatant; and sixth step, performing flash drying to obtain a brown yellow powder product. The technology provided by the invention overcomes the defects of the prior art, broadens the comprehensive utilization value of fruit raw materials, and solves the problems of low extraction rate of bioflavonoid and insecurity in the prior art.

Description

technical field [0001] The invention relates to the technical field of waste liquid reuse after pectin extraction, and specifically belongs to a production process for recovering bioflavonoids from ethanol waste liquid extracted from pectin. Background technique [0002] Natural pectin substances widely exist in the fruits, roots, stems, and leaves of plants in the form of protopectin, pectin, and pectic acid. They are a component of cell walls. They exist with cellulose and form adjacent Adhesives in the middle layer of cells make plant tissue cells tightly bonded together. Pectin can accelerate wound healing. After pectin is extracted, its waste is ethanol waste liquid. Among them, bioflavonoids are plant secondary metabolites, and they are not single It is a general term for a variety of compounds with similar structures and active substances, and is called bioflavonoids because they are mostly yellow. The main vitamin P compounds include flavonoids, rutin, hesperetin, e...
