Description

A kind of extraction and refinement method of high anti-oxidation dietary fiber
Technical field
It is effective by improving more particularly, to one kind the present invention relates to a kind of method that utilization waxberry dregs obtain through refining dietary fiber The method that the method for polyphenol substance obtains through refining high anti-oxidation dietary fiber.
Background technology
The subtropical evergreen fruit trees of Myrica(Myrica) Myruca ceas, fruit is that cedductor shape is spherical, there is small nut.General single fruit weight is 10 g Left and right, belongs to berries.Ming Dynasty's physician's Li Shizhen (1518-1593 A.D.) claim its " shape for example bigcatkin willow son and taste like plum, it is therefore named." red bayberry be China special product One of, Southeast China each province and the Yunnan-Guizhou Plateau are originated in, cultivation history is long, is the characteristic fruit tree of Chinese Famous, it is widely distributed In In Middle And Lower Reaches of Changjiang River and all provinces of Southwestern China, there is the province such as Zhejiang, Jiangsu, Fujian, Hunan, Jiangxi and Guangdong major production areas. In recent years, with industry restructuring and Integrated Development of The Mountainous Region, red bayberry cultivated area expands rapidly, according to incompletely statistics, currently The total output of China red bayberry is 800,000-100 ten thousand t, the hm of cultivated area about 11.5 ten thousand2.Red bayberry is used as China's characteristic fruit, fruit Lovely luster, juice is more, sweet and sour palatability, with rich flavor, rich in nutritional ingredients such as multi mineral prime element, vitamin, amino acid, It is of high nutritive value.According to《Compendium of Materia Medica》Record:Waxberry fruit " can quench the thirst, and the five internal organs, wash stomach, relieving restlessness burst bad odor.Mild-natured, nothing Poison, with helping digestion, relieve summer heat, cough-relieving of promoting the production of body fluid, aid digestion, antidiarrheal diuresis " the effects such as, since ancient times, red bayberry is used to treatment diarrhoea And enterogastric diseases, with slaking thirst and help produce saliva, the health-care efficacy such as the preventing or arresting vomiting that helps digestion, treatment dysentery.
At present, China red bayberry is still based on marketing fresh, and the ratio of processing is about 40%, and main converted products includes red bayberry fruit The products such as juice, red hayberry wine, canned arbutu, candied fruit, have been carried out industrialized production.Produced every year in production substantial amounts of Waxberry dregs.These waxberry dregs are largely disposed in addition to sub-fraction is used as feed manufacturing, not only cause certain environment dirty Dye, also results in the wasting of resources.According to the literature in waxberry dregs contain substantial amounts of dietary fiber, its content more than 60% to 70%, The method that traditional waxberry dregs obtain through refining dietary fiber is extracted using the acid-base method of chemistry, and the method not only have lost substantial amounts of meals Fiber is eaten, is also destroyed the polyphenols in fiber, therefore the yield of dietary fiber is not high, inoxidizability is relatively low.
Our province red bayberry aboundresources, two ranks degraded by raw material of waxberry dregs through polyphenol oxidase enzymatic inactivation and insoluble fibre Red bayberry dietary fiber is obtained through refining using enzyme process after section processing, the dietary fiber of high-quality, water soluble dietary fiber content can be obtained Ratio increase by 20%, inoxidizability increase by 40%, the good advantage of the active strong, effect of the product of exploitation, due to obtain through refining link without Organic solvent residual, thus with green non-pollution the characteristics of.
The content of the invention
It is an object of the invention to provide a kind of strong high-quality dietary fiber of inoxidizability, while solving the profit of waxberry dregs With and processing, new pattern is provided for red bayberry comprehensive processing and utilization.
The present invention suppresses the oxidation of polyphenols in waxberry dregs by being passivated the method for polyphenol oxidase, then passes through second Dietary fiber in the dematuration softening waxberry dregs of alkene, in favor of the degraded of follow-up insoluble diedairy fiber, further lifting The inoxidizability of red bayberry dietary fiber, obtains the red bayberry dietary fiber of high antioxidant, is achieved through the following technical solutions 's.
(1)High temperature is passivated:By waxberry dregs 100 DEG C it is xeothermic it is lower keep 10 minutes, make polyphenol oxidase enzymatic inactivation;
(2)Ethene softens:Ethene was passed through at the 5th minute, concentration is maintained at 800-1000 ppm, makes fibr tissue soft Change;
(3)Enzymolysis:By 3:1 solid-liquid ratio addition warm water, while make red bayberry slag-water slurry be cooled to 60 DEG C~80 DEG C, side Side is stirred to react 30 minutes by 400-450 mg/L addition cellulases;
(4)Complex enzyme hydrolysis:Digested by 0.1%~0.5% addition complex enzyme of waxberry dregs dry powder quality, complex enzyme is by forming sediment Powder enzyme and papain press 3:1 composition, during enzymolysis pH value control be 6~8, hydrolysis temperature control 60 DEG C~80 DEG C, enzyme The solution time is 60min~90min;
(5)Filtration drying:By the mixture filtering after enzymolysis, filter residue drying red bayberry dietary fiber powder.
It is an advantage of the invention that:Technological process is simple, and the production time is short, and polyphenols can be preserved fully, and product is in shallow Red, obtains through refining process environmentally safe.
