Summary of the invention
In order to overcome the existing cost height of glycosidase and the uncertain problem of security of adopting, primary and foremost purpose of the present invention is to provide a kind of production method of debitterize pomelo peel, the method utilizes the glycosidase of lactic acid bacteria secretion when growth to act on the glucosides that produces bitter taste, plays the effect that removes bitter taste.
Another object of the present invention is to provide the debitterize that is prepared by said method pomelo peel.
The purposes of the debitterize pomelo peel that a further object of the present invention is to provide above-mentioned.
Purpose of the present invention is achieved through the following technical solutions:
A kind of production method of debitterize pomelo peel may further comprise the steps:
(1) pulp with shaddock separates with pericarp, and pomelo peel is cut into small pieces;
(2) preparation mass body volume concentrations is 5~20% sugar juice, and it is boiled; Mass ratio by shaddock ped piece and white granulated sugar solution is 1:(3~5), add the shaddock ped piece, be stirred and heated to 95~100 ℃, insulation 5~10min is with sterilization, and then shaddock ped piece white sand liquid glucose is cooled to below 37 ℃ under aseptic condition;
(3) access lactic acid bacteria in shaddock ped piece white granulated sugar solution, in shaddock ped piece white granulated sugar solution gross mass, the viable count of lactobacillus of interpolation is 10
5~10
7Cfu/g, after stirring, 37 ℃ of bottom fermentations are cultivated 24~72h, are warming up under 90~95 ℃, and insulation 30~40min after the cooling, pulls the shaddock skin bit with sterilization out, drains, and namely makes the shaddock skin bit behind the debitterize;
The described sugar of step (2) is more than one in white granulated sugar, glucose or the lactose.
The described lactic acid bacteria of step (3) is more than one in Lactobacillus plantarum, lactobacillus acidophilus or the Lactobacillus casei, gets final product by the equal proportion interpolation when adopting two or more lactic acid bacterias.
The debitterize shaddock parchment that said method makes can be applied in the food industry, such as for the preparation of shaddock ped preserved fruit, honey citron tea, shaddock ped jam and pomelo beverage etc.
The application's debitterize principle is to utilize glycosidase secreted in the lactobacter growth process to act on main bitter material---limonin (glucosides class) in the shaddock, remove the bitter substance of shaddock by the conversion technology that adopts microbial fermentation, respond well, but also because the fermentation of lactic acid bacteria has produced new flavor substance and nutriment, this is to generally acknowledge and accept for vast research and production technical staff at present.The application's debitterize principle and " preparation method of debitterized honey pomelo soybean yoghurt " (application number: 200810156413.3) fully different.
The present invention has following advantage and effect with respect to prior art:
It is moderate, mellow fresh and sweet that the debitterize shaddock ped that the inventive method makes has tart flavour, the characteristics that local flavor, mouthfeel etc. all can satisfy the demands of consumers, and basically removed the shaddock ped bitter taste, the debitterize pomelo peel of producing can be used for producing other series of products, such as shaddock ped preserved fruit, honey citron tea, shaddock ped jam and pomelo beverage etc., shaddock processing new varieties have been increased, can improve the associated production vendor's benefit, satisfy the ever-increasing demand of consumers in general, have higher economic benefit and social benefit.
The inventive method also is applicable to the debitterize of other cedra fruits converted products and processes.
