Production Process Optimization of Function Loquat Tablets

Using loquat as mainly raw materials，other materials were added to produce a new product，loquat tablets.Firstly，color technology of loquat piece was determined.Then，add accessories were selected，add accessories ratio was determined.Finally，optimization of heat cooking temperature，drying time and drying temperature were made sure.Using multi-oxidase as indicators，effects of pH value and temperature on browning enzyme activity were researched through single factor experiment.Results showed that high temperature and low pH value could inhibit the activity of multi-oxidase.Then effect of ascorbic acid，organic acids for color were studied.Results showed that ascorbic acid was effective when concentration of 250 mgkg.Potato powder，white sugar and edible colloid were selected as major raw materials，with sensory evaluation value as indicator，optimum adding amount of potato powder，white sugar and edible gum were determined by single factor test and orthogonal test，which were 15%，12% and 6%.Cooking temperature，drying time and drying temperature were selected，with moisture content as the index，optimum process parameters were studied.Results showed that boiling temperature 100 ℃，boiling time 30 minutes，drying time 120 minutes and drying temperature 75 ℃ were the best technical parameters.
