The rheological properties of zein, wheat gluten and other raw materials, as the carrier bamboo shoots, and discusses the process and biodegradable bamboo shoots environmentally friendly chewing gum, and chewing gum base depth study. The main findings are as follows: single factor and orthogonal experiment acid and enzyme protein modification chewing gum base. The results show that: the best acid solution modified acid was 2%, acid hydrolysis temperature of 40 ° C, acid hydrolysis time of 30 min; optimum conditions for the enzyme dosage 0.2%, pH 6, enzyme The solution temperature of 40 ° C, the the enzymatic time of 25min. Enzymatic Modification than acid LRC performance better chewing gum base. Comparative gum base in the different pH, temperature, shearing force, and a plasticizer under conditions change in viscosity of the protein solution, to determine the protein solution of gum base for pseudoplastic non-Newtonian fluid. Comparing wheat gluten, zein, and an emulsifier for the gum base mechanical properties i.e. tensile strength, elongation at break, determined the amount of the gum base in the wheat gluten, zein, glycerine added respectively 60%, 15%, 8% more appropriate. Single factor and orthogonal experiment to determine the best bamboo leaves Extraction Process: ethanol concentration 10%, microwave irradiation time of 5min, solid-liquid ratio of 1:12, the maximum extraction rate: 7.74%. The chewing gum base is filled into the bamboo shoots, the aging conditions of 50% relative humidity, 25 ° C the temperature, 10h drying time. Carrier prepared to shoot for the best formulation of the environmental health of chewing gum: gum base 35% bamboo leaf extract 25%, 20% maltose syrup, powdered sugar 15%, 4% sorbitol, citric acid 0.4%, the flavors and the right amount, moisture content of 30%. Bamboo shoots environmentally friendly chewing gum chew add residues in human microbial culture to achieve 60% -100% of the sample surface microbial growth, weight loss rate of 67.00% after 28d. The bamboo shoots, environmentally friendly chewing gum chew the residue buried into law three months after the weight loss rate of 69.35%, the tensile strength decreased from 1.48MPa to 0.42MPa. Comprehensive comparison, bamboo shoots environmentally friendly chewing gum Doublemint gum and butyl rubber gum biological degradation effect. In summary, prepared bamboo shoots environmentally friendly chewing gum, gum base by using wheat gluten as the main raw material filled into the bamboo shoots not only solve the problem of chewing gum pollution of the environment, but also due to the addition of a bamboo leaf extract improves gum health functions, fresh breath, so the prospects are very bright.
