Study On Preparation Technology And Parameter Optimization Of Black Corn And Bamboo Shoot Chewable Tablets

This article uses black corn and bamboo shoots as raw materials to study the preparation and processing technology of black corn bamboo shoot chewable tablets.Through a series of tests,the best process conditions are obtained.The main research contents and results of this study are as follows:1.Select fresh black corn without obvious mechanical damage and decay.The effects of four color-protecting agents: ascorbic acid concentration,citric acid concentration,L-cysteine and L-malic acid concentration on the browning degree of black corn were determined.Through single factor test and orthogonal test,the best composite color protection agent for black corn is: ascorbic acid concentration 0.4%,citric acid concentration 0.3%,L-cysteine concentration 0.35%,L-malic acid concentration 0.15%,2.By measuring the moisture content and melanin extraction rate of black corn at different drying temperatures,and according to the sensory evaluation score of black corn at different drying temperatures,the results show that: when the drying temperature is 60 ℃,the moisture content of black corn meets the requirements,Below 8%,the extraction rate of melanin is the highest,and the sensory evaluation score is the highest.The best drying temperature of black corn is 60 ℃.3.By measuring the moisture content and melanin extraction rate of black corn at different drying times,and according to the sensory evaluation score of black corn at different drying temperatures,the results show that when the drying time is 12 h,the moisture content of black corn meets the requirements,low At 8%,the extraction rate of melanin was the highest,and the sensory evaluation score was the highest.The best drying temperature of black corn was 12 h.4.By measuring the moisture content and polysaccharide extraction rate of bamboo shoots at different drying temperatures,and according to the sensory evaluation score of bamboo shoots,the results show that: when the drying temperature is 60 ℃,the moisture content of bamboo shoots meets the requirements,less than 8%,polysaccharide extraction The highest rate,the highest sensory evaluation score,the best drying temperature of bamboo shoots is 60 ℃.5.By measuring the moisture content and polysaccharide extraction rate of bamboo shoots at different drying times,and according to the sensory evaluation score of bamboo shoots,the results show that when the drying temperature is 16 h,the moisture content of bamboo shoots meets the requirements,less than 8 %,the polysaccharide extraction rate The highest,the highest sensory evaluation score,the best drying temperature of bamboo shoots is 16 h.6.Through single factor test and orthogonal test,the best formula of black corn bamboo shoot chewable tablets is: black corn flour 40 g,bamboo shoot powder 10 g,xylitol 7.5 g,microcrystalline cellulose 7.5 g,menthol 3.5 g,6.0 g of non-dairy creamer.7.Using the pellet forming rate as an indicator,determine the pellet forming rate at different drying temperatures and different drying times,and find that the optimal pelletizing drying temperature is 55 °C and the optimal pelletizing drying time is 2h.8.Through a series of tests,a new type of chewable tablet has been developed.The chewable tablet has a delicate taste,a unique flavor,and good chewability.The content of active ingredient is: each 1g chewable tablet contains melanin 8.476 mg,polysaccharide 80.874 mg,and total flavonoid content 31.352 mg.
