Abstract
The invention discloses a method for extracting a food natural oxidation inhibitor from green coffee bean powder, which comprises the following steps of: preprocessing the coffee bean powder; dissolving; decalcifying; filtering, concentrating and adding acid; decolorizing; and carrying out vacuum freezing to obtain light yellow dried powder, i.e. the food natural oxidation inhibitor. The method has the advantages that the method has simple production process, is easy to operate and control and has good economic benefit and social benefit.
Description
Technical field:
The present invention relates to a kind of extraction process of food antioxidant, particularly a kind of method of extracting natural food antioxidant from the green coffee bean powder.
Background technology:
Improving constantly of Along with people's living standard, people are increasingly high to the environmental protection and the safety requirements of food, and food antioxidant is used by a large amount of.In the prior art; Food antioxidant is generally processed with the reaction of chemical industry method; The food antioxidant that the reaction of chemical industry method is processed is just paid attention to by People more and more the toxic and side effect of human body, and natural food antioxidant is to receive people's welcome, and fresh coffee beans is except that containing caffeine; Also contain materials such as protein, amino acid, chlorogenic acid; Fresh coffee beans contains materials such as chlorogenic acid, caffeic acid, amino acid through the pale yellow powder that hot water extracting obtained, can be used as each quasi-grease, the natural inhibitor of aquatic food.At present, the rare report that extracts natural food antioxidant from the green coffee bean powder.
Summary of the invention:
For solving the deficiency of prior art, the invention provides a kind of method of extracting natural food antioxidant from the green coffee bean powder.
The present invention is achieved in that a kind of method from green coffee bean powder extraction natural food antioxidant, it is characterized in that, may further comprise the steps:
One, fresh coffee beans is ground into adds band behind the powder and press in the flask of mixing device and reflux condenser, add n-hexane, at room temperature fully stirred 4 hours; Fully remove lubricant component wherein; The green coffee bean powder is filtered, and n-hexane reclaims, and filter cake is the good coffee bean powder of preliminary treatment.
Two, in the flask that has reflux condenser and agitator, add the above-mentioned coffee bean powder of handling well 50 grams, 200 milliliters of pure water, calcium hydroxide 10 grams; Heat temperature raising to 90～95 ℃, insulation refluxed 2～3 hours.
Three, be chilled to room temperature after, add an amount of phosphoric acid, the pH value of regulating flask contents is 7～8.Continue to stir 1 hour; Can generate calcium phosphate precipitation in the solution.
Four, with sedimentation and filtration, when filtrating under reduced pressure is concentrated into volume and reaches 100 milliliters of left and right sides, add citric acid, regulating pH value is about 5.
Five, concentrate is decoloured through the exchange column that ion exchange resin is housed.
Six, destainer is delivered to be evacuated rapidly in the hothouse and freezing, the steam that distillation generates borrows condenser to remove, and obtains faint yellow dried powder instant food natural inhibitor at last.
A kind of advantage of extracting the method for natural food antioxidant from the green coffee bean powder of the present invention is: production technology is simple, control easily, and economic benefit and social benefit are good.
The specific embodiment:
Below in conjunction with embodiment, the present invention is made further detailed description, but does not constitute any restriction of the present invention:
Embodiment one:
A kind of method from green coffee bean powder extraction natural food antioxidant is characterized in that, may further comprise the steps:
1, fresh coffee beans is ground into adds band behind the powder and press in the flask of mixing device and reflux condenser, add n-hexane, at room temperature fully stirred 4 hours; Fully remove lubricant component wherein; The green coffee bean powder is filtered, and n-hexane reclaims, and filter cake is the good coffee bean powder of preliminary treatment.
2, in the flask that has reflux condenser and agitator, add the above-mentioned coffee bean powder of handling well 50 grams, 200 milliliters of pure water, calcium hydroxide 10 grams; Heat temperature raising to 90 ℃, insulation refluxed 2 hours.
3, be chilled to room temperature after, add an amount of phosphoric acid, the pH value of regulating flask contents is 7.5.Continue to stir 1 hour; Can generate calcium phosphate precipitation in the solution.
4, with sedimentation and filtration, when filtrating under reduced pressure is concentrated into volume and reaches 100 milliliters of left and right sides, add citric acid, regulating pH value is about 5.
5, concentrate is decoloured through the exchange column that ion exchange resin is housed.
6, destainer is delivered to be evacuated rapidly in the hothouse and freezing, the steam that distillation generates borrows condenser to remove, and obtains faint yellow dried powder instant food natural inhibitor at last.
Embodiment two:
The process conditions of step 2 are heat temperature raising to 92 ℃, and insulation refluxed 2.5 hours, and is surplus with embodiment one.
Embodiment three:
The process conditions of step 2 are heat temperature raising to 95 ℃, and insulation refluxed 3 hours, and is surplus with embodiment one.
The natural food antioxidant that the present invention processes when making an addition in the food, can give the activity that food suppresses oxidases, prevents or to delay food oxidized, and it is mainly used in the oxidative rancidity that prevents grease and fat-rich food.General consumption is 0.2%～2.8%.
