Abstract
The present invention relates to a food antioxidant preserving agent extracted from raspberries. The present invention is characterized in that the food antioxidant preserving agent is prepared by the steps: pulverizing the whole fresh raspberries; adding water to carry out agitation, cooling and statically placing; filtering for slag removal; collecting filtrate; extracting the filtered slag by hot water twice; combining the filtrate; adjusting the pH to be from 9.5 to 10.5 by lime slurry; diluting the generated calcium salt precipitation; then, acidifying to remove the calcium salt by phosphoric acid and obtain compound solution with several kinds of polyphenol of the raspberries; concentrating and drying to prepare the food antioxygen preserving agent. The product has multiple functions of oxygen resistance, preserving and free radical elimination, and has the advantages and the effects of low cost, high product purity, no toxic or side effect and simple preparation method.
Description
Technical field
The present invention relates to a kind of food antioxidant fresh-keeping agent that extracts from raspberry, belong to the food additives field.
Background technology
Food antioxidant fresh-keeping agent is a class important foodstuffs additive in the food industry in modern age, main effect is blocking-up or the autoxidation iso-metamorphism process that delays multiple COF such as grease, thereby guarantee the nutrition performance and the quality of COF, food intrinsic properties such as local flavor stable.
Tea Polyphenols is to be the oil base food antioxidant additive of a kind of anti peroxidation of lipid of raw material with tealeaves and tea processing factory's leftover bits and pieces, but when at present both at home and abroad extracting Tea Polyphenols mostly with an organic solvent and heavy metallic salt, its method complexity, many drawbacks such as cost height, also the leaf of useful raspberry is made antistaling agent, but method therefor also is an organic solvent extracts its method complexity of the same described part of its shortcoming, cost height.
Summary of the invention
Purpose of the present invention is that a kind of of raw material extracts the antioxidant fresh-keeping agent product from raspberry for the shortcoming that overcomes above-mentioned prior art provides with deficiency with the fresh raspberry of complete stool just, thereby, improved the food fresh keeping phase to the antioxygen of food, fresh-keeping, elimination free radical multiple efficacies.
The objective of the invention is to realize by following technical proposal:
Food antioxidant fresh-keeping agent from raspberry is extracted is characterized in that it is that raw material is made as follows with the raspberry:
(a) the fresh raspberry water of complete stool is cleaned up powder essence to 4～5mm again, 80～100 ℃ of hot water of 8～10 times that add raspberry weight in the adding reactor again stir and made temperature reduce to 75～80 ℃ in 10～20 minutes, stop to stir, left standstill 4～6 hours, filter cleaner, collect filtrate, filter residue made temperature reduce to 75～80 ℃ in 10～15 minutes with 5～7 times of capable stirrings of 80～100 ℃ of hot water again, stop to stir, left standstill 2～4 hours, filter cleaner, filter residue repeat once by above-mentioned condition again, merge three times filtrate
(b) slowly add lime slurry in the filtrate of (a) item and make solution become khaki by drabon look, PH9.5～10.5 make polyphenolic substance generate calcium precipitation;
(c) natural subsidence is separated the calcium precipitation thing of (b) item, 2～5 times the water that isolated polyphenolic substance calcium precipitation adds the sediment volume dilutes, use phosphoric acid acidifying calcium precipitation thing to solution PH 6～6.5 again, remove calcium salt after filtration, obtain containing the multiple polyphenolic substance solution of raspberry, filter residue can use with soil improvement is fertile;
(d) at last with the solution of (c) item, concentrate drying is food antioxidant fresh-keeping agent product of the present invention according to a conventional method, and product composition is:
Polyphenolic substance total amount 40.22～41.18%
The anthocyanidin total amount is 35.54～36.37%
The vitamin C total amount is 8.70～8.92%
The vitamin E total amount is 0.42～0.44%
The beta carotene total amount is 0.12～0.13%
Other are 15.00～12.96% years old.
This food antioxidant fresh-keeping agent is used for the fresh-keeping of food, and its consumption is 0.1～0.4g/kg.
It is raw material that the present invention selects the complete stool raspberry, and it is the perennial machaka type fruit tree of rose family rubus, its fruit soft and succulency, and unique flavor once was described as " king of world's fruit "; Fruit of raspberry and leaf, stem, root are rich in multiple nutritional components such as multiple polyphenolic substance, anthocyanidin and superoxide dismutase SOD and vitamin C, vitamin E, beta carotene.Anthocyanidin, content is up to 31～53mg/100g fresh fruit, this is one of main body composition of non-enzyme in the free radical scavenger of generally acknowledging, next is to be rich in multiple antioxidant content, be the different polyphenolic substances of various structures, comprise ellagic acid, gallic acid, catechuic acid, caffeic acid, coumaric acid, forulic acid, adjacent diphenol, salicylic acid, p-hydroxybenzoic acid, poplar acid, p-hydroxybenzoic acid, straight 40～60mg/100g the fresh fruit of total polyphenols compounds content, wherein ellagic acid is the active component of very attracting attention, content is up to 1.6～2.1mg/100g fresh fruit, various Flavonoid substances are also very abundant in the raspberry, total amount has very strong removing free radical activity at 4.5～5.5mg/100g fresh fruit.Be rich in simultaneously so extensively, so numerous polyphenol things is added contained anthocyanidin, and containing hepatocuprein SOD content in content and the fruit is 150～230ug/g fresh fruit, this is real in many plants to be rare, becomes the valuable source of natural antioxygen fresh products exploitation.
Except that the resource of fruit as the raspberry exploitation, a large amount of raspberry leaves, the raspberry root of discarding when stem and orchard are upgraded also is the valuable source that obtains precious raspberry polyphenolic substance.
But the multiple efficacies of raspberry active component antioxygen, fresh-keeping and Green Tea Extract.
At the edible oil and fat fresh-keeping aspect, confirm that also its antioxidant capacity is to use antioxidant such as vitamin E, BHA, BHT 3～9 times at present.
In view of the important meaning of polyphenolic substance to food industry and medical material industry, the character that the present invention is many in conjunction with raspberry polyphenol quantity, kind is numerous, according to the polyhydric characteristics of polyphenolic substance, employing adds the calcium salify, again through the method for phosphoric acid acidifying, extract the raspberry polyphenol, obtain the goods of polyphenolic substance.
Owing to take technique scheme to make the technology of the present invention compared with the prior art have following advantage and effect:
(a) the raspberry raw material sources are wide, cost is low, product purity is high, can reach 85～87%, have no side effect,
(b) preparation method is simple, extracts the productive rate height,
(c) product have antioxygen, fresh-keeping, eliminate the multiple function of free radical, fresh keeping time is to use antioxidant such as vitamin E, BHA, BHT 3～9 times at present.
