The Study On Bamboo Shoots Dietary Fiber Microcapsule Embedment Compounding And Its Functional Characteristic

The bamboo shoots byproduct is used for producing dietary fiber, exactly the processing technology of bamboo shoots dietary fiber and compound dietary fiber microcapsule as well as their functional character are studied roundly and detailedly in this text. The results are as followed:In the first step, bamboo shoots dietary fiber is produced by way of chemical, enzymatic and zymotic methods in this research, compare their chemical composing,physic and chemical character of the products as well as their microcosmic modality, and optimize the scheme of fermentation to produce dietary fiber. The best zymotic project of producing bamboo shoots dietary fiber is as followed:inoculum's content 12%, temperature 44℃, time is 20 hours; yield 3.66%, content of SDF 12.03g/100g, IDF 48.36g/100g; and its WHC, SWC and CEC are respectively 6.19g water/g sample,4.92ml water/g sample,0.239mmol/g sample; the maximum binding of bile acid is 5.8mg/g; the max binding of heavy metal ion Ag+,Pb2+, Cu2+ is 65.5,35.6 and 32.7umol/g. The results of infrared spectra analysis shows the characteristic of the figure of zymotic product is:1735.20 cm-1 C=O stretching vibration absorption peak shows ketone/aldehye the main characteristic absorption peaks; fingerprint 1541.49 cm-1 aromatic skeleton vibration absorption peak of the absorption peaks several enhanced, and 1319.10cm-1 belong to a carboxylic acid dimer (1320cm-1-1210cm-1) C-O stretching vibration. Compare zymotic and no zymotic dietary fiber by electric mirror scanning, we find that there is so much mycelium in the zymotic dietary fiber.During the second step, embed and compound the zymotic bamboo shoots dietary fiber, pectin and other nutriment, and optimize its technology by orthogonal test. Test these sample from the physical and chemical character, microcosmic modality and other aspect. Through single-factor test and Orthogonal drawn, bamboo shoots of the optimal dietary fiber microencapsulation technology for embedding Composite is, emulsifiers for Tween 80 (0.2%)+ester alone anhydride (0.1%),1 percent Pectin for embedding agent, wall-core ratio of 3 to 7:bamboo shoots dietary fiber composite embedded micro-capsules; spray drying out of the wind temperature was 175℃,65℃, material flow rate of 0.6 ml/s. All physic and chemical standards get improvement compared single dietary fiber, they are as followed:WHC, SWC and CEC are respectively rises by 14.85%,10.85 and discreases by 60%; viscosity value 30.6 MPa.s, as bigger as 10 and 15 times bigger than single wall material and core material viscosity value; the adsorption and combined capacity of bile acid molecular is of 7.9mg/g sample, rises by 38.6% compare core material. The outcome of infrared spectra analysis expresses only compound dietary fiber embedded with 1% pectin contains the characteristic adsorption of aromatic ring 1549cm-1, basically makes the reappearance come true of main material bamboo shoots dietary fiber compared with the spectra of simple compound dietary fiber.The result shows:fermentation is better than other methods as well as its product. and there is plentiful mycelium in it, which is the another reason that zymotic dietary fiber has more nutrition than not zymotic; and then validated that the function and characteristics of zymotic dietary fiber are better than single dietary fiber. The result of micro observation and infrared spectra analysis proves the embedment and compounding of compound bamboo shoots dietary fiber granule is successful, it is feasible to embed and complex bamboo shootss dietary fiber. and achieve the aim of increase the content of SDF, improve taste, texture and moisture-resistant as this research pursues.As discussed above, the bamboo shoots drink or can byproduct is made use of producing dietary fiber, and then compounded to multifunctional dietary fiber product, it makes that kill two birds with one stone come true, not only bring good message for the people who catch so much sickness as a result of imbalance of biting and supping, but also make the bamboo shoots is utilized efficiently and synthetically, which has expansive applied foreground.
