The invention relates to a method for extracting dietary cellulose from manioc slag. According to the method, the manioc slag is used as raw materials, and the manioc base dietary cellulose is obtained through acidolysis, alkali treatment, decoloration, drying and crushing. The method has the advantages that the process is simple, the cost is low, an acid and alkali combination method is utilized for extracting the dietary cellulose, the integral development and utilization of the manioc slag is favorably realized, the obtained products conform to the national standard, and the method belongs to an environment-friendly dietary cellulose extracting method and has the characteristics that the green and environment-friendly effect is realized, the yield is high, the acid and alkali consumption is little, and the like.
Description
Technical field
The present invention relates to a kind of method for distilling of cassava base dietary cellulosic, be specifically related to a kind of method of utilizing manioc waste to extract dietary cellulosic under suitable condition through acidolysis, alkali treatment, oxidative decoloration.
Background technology
Manioc waste is the discarded object after the cassava suitability for industrialized production, and the manioc waste output of processing at the only annual tapioca of China has 300,000 tons, adds that the manioc waste of processing other products such as alcohol adds up 1,500,000 tons.A large amount of manioc wastes go out of use, and not only cause the wasting of resources, and serious environment pollution, to the utilization research of manioc waste, mainly concentrate on the production feed both at home and abroad, and active carbon, single cell protein, oxalic acid, culturing edible fungus reach aspects such as going back the field.
Dietary fiber is the carbohydrate that a kind of difficult quilt digests, and mainly comes from the cell membrane of plant, comprises cellulose, hemicellulose, pectin and lignin etc.Dietary fiber is keeping playing the part of important role on the digestive system health; The enough fiber of human intake can angiocardiopathy preventing, cancer, diabetes and other disease; And dietary fiber can clean wall of digestive and strengthen digestive function, and fragile alimentary canal and prevention colon cancer are protected in removing of carcinogen in dilution and the acceleration food and noxious material; Slow down digestion rate and rapid drainage cholesterol, make blood sugar and cholesterol in the blood be controlled at optimal level.
At present, the method for distilling of dietary fiber mainly contains acid system, Mechanical Method, alkaline process, fermentation method, enzyme process etc., and the technology of wherein using more acid system, alkaline process is comparatively complicated, and the use amount of acid, alkali is high, is prone to environment is polluted.
Summary of the invention
The objective of the invention is to the deficiency of prior art and a kind of method of from manioc waste, extracting dietary cellulosic is provided; Utilize the soda acid combined techniques to extract dietary fiber; Help the comprehensive exploitation and the utilization of manioc waste; The products obtained therefrom National standard, characteristics such as have that technology is simple, cost is low, environmental protection, productive rate consumption high, soda acid are few are a kind of method for distilling of environmentally friendly dietary cellulosic.
The technical scheme that the present invention adopted:
A kind of method of from manioc waste, extracting dietary cellulosic, its step is following:
1, acidolysis: get edible inorganic acid or the organic acid soln of manioc waste, be heated to 75～85 ℃ of hydrolysis, cross and filter filter residue according to the ratio adding 20% of solid-liquid ratio 1: 1～5.
2, alkali treatment: the filter residue of step 1) gained is added 20% edible alkali solution according to the ratio according to solid-liquid ratio 1: 5～8,80～100 ℃ of heating 2～5h, refilter filter residue.
3, decolouring: with step 2) filter residue of gained adds 30% H according to the ratio according to solid-liquid ratio 1: 1～2
2O
2Solution, and to use edible adjusting PH with base be 9.5～10.5 leaves standstill and observes deposition and be pure white and promptly accomplish decolouring, crosses and filters filter residue.
4, drying and crushing: the filter residue of step 3) gained is got cassava base dietary cellulosic finished product in 80～110 ℃ of crushed after being dried.
Among the present invention, the acidolysis process is that 1: 4 ratio adds 20% sulfuric acid and heats 2h according to solid-liquid ratio preferably, and acidolysis effect is best.
Among the present invention, decolorization preferably is the H of 1: 1.2 ratio adding 30% according to solid-liquid ratio
2O
2Solution, using edible adjusting PH with base is 10 as pH, and is heated to 60 ℃, decolouring is very fast.
Detect:
Products obtained therefrom of the present invention is carried out infrared spectrum detect, the gained result is as shown in Figure 1.3418cm in infrared spectrum
-1The stretching of the absorption representative-OH at place, 2919cm
-1The stretching of C-H is represented in the absorption at place; 1637cm
-1The absorption at place is because absorbing the bending of water causes, at 1161cm
-1The absorption at place is stretched by the C-O antisymmetry and causes, at 895cm
-1The strong absorption peak represent C1 group vibrational frequency or ring vibration frequency, this is the characteristic absorption peak of β glycosidic bond vibration between the glucose unit, proves that in sum this product is a cellulose.
Technology of the present invention is simple; Cost is low; Utilize the soda acid combined techniques to extract dietary fiber, help the comprehensive exploitation and the utilization of manioc waste, the products obtained therefrom National standard; Having characteristics such as environmental protection, productive rate are high, the consumption of soda acid is few, is a kind of method for distilling of environmentally friendly dietary cellulosic.
