Abstract

The production process for extracting rutin (total ketone) from buck wheat includes the following procedures: preparing buck wheat seeds, washing by water, coarse grinding, coarse screening, soaking in water, drying in the air, properly fine-grinding, soaking in edible alcohol, extracting below 60 deg.C, filtering and obtaining rutin (total ketone). Said invention fully utilizes rich resource of buck wheat, and has the advantages of high rutin (total ketone) yield, good quality and low energy consumption, etc..

Description

Bitter buckwheat extracts the production technique of rutin (total ketone)

The present invention relates to a kind of process for producing rutin, particularly a kind of production technique of from bitter buckwheat, extracting rutin (total ketone).

Rutin can also can be used as foodstuff additive directly as medicine, in the prior art, generally adopts the sophora bud to extract rutin as raw material, and the technology of extracting rutin with the sophora bud is more complicated all, and raw material is restricted.

The objective of the invention is to: the production technique that the buckwheat Seed extraction rutin (total ketone) of the bitter buckwheat of a kind of usefulness is provided.

The present invention is achieved in that its processing step is:

A, bitter buckwheat seed wash with water, the corase grind, scalping, on the sieve buckwheat Seed;

B, with the buckwheat Seed entry, remove the floating thing that anhydrates, pull throw out out, remove free-water, airing, suitably fine grinding with edible ethanol, is soaked more than 24 hours, in extraction below 60 ℃, filter, the filtrate evaporate to dryness, doing the back material is rutin (total ketone).

The present invention compared with prior art has following advantage:

1, adopting the production technique of bitter buckwheat extraction rutin (total ketone), make full use of the affluent resources of the bitter buckwheat of Guizhou Province's fecund, with the buckwheat Seed extraction rutin (total ketone) of bitter buckwheat, turn waste into wealth, is rare cheap natural preparation rutin raw material, so production cost is low;

2, the present invention is because processing step is few, and equipment is simple, and processing ease is saved starting material to greatest extent, so less investment, and instant effect is suitable for suitability for industrialized production;

3, adopt the present invention to extract rutin (total ketone), have rutin (total ketone) yield height, quality is good, and few advantage consumes energy.

The embodiment of the invention: bitter buckwheat seed is washed with water, remove sand, mud, with mill corase grind, scalping, on the sieve buckwheat Seed, buckwheat Seed is immersed in the water, remove the floating thing that anhydrates, pull throw out out, remove free-water, airing, suitably fine grinding, the powder under the mill are soaked more than 24 hours with edible ethanol, 55 ℃ of extractions down, filter the filtrate evaporate to dryness, alcohol reclaims, and the evaporate to dryness thing is rutin (total ketone), and filter residue is as producing wine or feed.

Claims (1)

1, a kind of bitter buckwheat extracts the production technique of rutin (total ketone), and it is characterized in that: its processing step is:

A, bitter buckwheat seed wash with water, the corase grind, scalping, on the sieve buckwheat Seed;

B, with the buckwheat Seed entry, remove the floating thing that anhydrates, pull throw out out, remove free-water, airing, suitably fine grinding with edible ethanol, is soaked more than 24 hours, in extraction below 60 ℃, filter, the filtrate evaporate to dryness, doing the back material is rutin (total ketone).
