Abstract
The present invention belongs to a preparation method for a natural oxidation inhibitor of beet haematochrome. Beet haematochrome in edible red beets is extracted. The natural oxidation inhibitor has pure colors and strong coloring power, contains certain nutrient components, and is widely used in the industry of food, medicines, cosmetics, etc. In the present invention, raw materials are extracted from edible plants, and a natural oxidation inhibitor of beet haematochrome is obtained by mixing, desiccation, temperature control and pH value control. The oxidation inhibitor has strong light stability, thermal stability, simple preparation method, easy operation and low cost. The cost of a compound natural oxidation inhibitor is only one ninth of that of beet haematochrome.
Description
The invention belongs to the preparation method of betanin pigment as natural antioxidant
From edible red beet, extract beet red pigment, colour purity just, bright-coloured, strong coloring force contains certain nutrition, at food, industry widespread uses such as medicine and makeup.But the beet red pigment less stable is heated or is seen that light easily fades, variable color, limits and has influenced use.Therefore, select suitable natural oxidation inhibitor and development composite natral oxidation inhibitor, improve the stability of beet red pigment, keep its natural sex, to the broadened application field, its significance of having exploited market.
9 years reports of Japan's " food and exploitation " magazine tea shaddock juice can make beet red stability improve more than 20%.
The objective of the invention is from food plant, to extract raw material, obtain betanin pigment as natural antioxidant through mixing, drying, controlled temperature and pH value.
The present invention selects embedding tocopherol (weight ratio) 12～18%, phytic acid 5～15%, tea-polyphenol 40～50%, xitix 25～35%, synthesis step, earlier with tocopherol beta-cyclodextrin embedding, the weight ratio of tocopherol and beta-cyclodextrin is 40～20%: 60～80%.At hig h-speed centrifugal spray drying equipment inner drying, 220～200 ℃ of inlet temperatures, 80～90 ℃ of temperature outs, under 15～25 ℃ of conditions, add xitix, phytic acid, tea-polyphenol in the citric acid solution of PH4～6 successively, the embedding tocopherol then, mix the back hig h-speed centrifugal spray drying, 180～200 ℃ of inlet temperatures, 70～90 ℃ of temperature outs obtain white-pale yellow powder shape natural oxidation inhibitor at last.
Natural oxidation inhibitor is added in the beet red pigment, be mixed with 1% solution, test is to the stability of light and heat.
Transformation period: under 100 ℃ of conditions, pigment absorbance A value reduces half required time, and not adding oxidation inhibitor is 4080 seconds, and adding oxidation inhibitor is 8880 seconds.
The differing temps test-results is: 100 ℃ did not add oxidation inhibitor degradation rate 34.3% in 0.5 hour, and adding oxidation inhibitor is 10.8%; 80 ℃ 1.0 hours, do not add oxidation inhibitor degradation rate 33.9%, adding the oxidation inhibitor degradation rate is 0; 60 ℃ 1 hour, not adding the oxidation inhibitor degradation rate is 2.5%, adding the oxidation inhibitor degradation rate is 0.
Different light test-results: under 20 ℃ of directing light conditions, do not add oxidation inhibitor degraded in 8 days degraded in 14.5%, 16 day degraded 53.2% in 33.5%, 28 day, add oxidation inhibitor degraded in the 16th day degraded 6.0% in 4.9%, 28 day.Do not add oxidation inhibitor degraded in the 8th day 4.9%, 16 day 18.7%, 28 day 30.8% under 15 ℃ of scattered light conditions, add oxidation inhibitor degraded 2.4% in the 28th day.
The result shows that the transformation period prolongation more than one times, obviously increases light, thermostability.
The oxidation inhibitor of the present invention preparation all extracts from edible planting (moving) thing, and compound method is simple, easy handling, cost is low, composite natral oxidation inhibitor only be beet red pigment cost 1/9th.
