Studies On The Usage Technology Of Watermelon Pulp

The plant area of Watermelon in China is about 1800 hectares a year and total output is more than 35 million tons, the country's annual production of watermelon need about 1500 tons of watermelon seeds, which takes about more than 100,000 tons of watermelon used for seeds.After off-seeds,the watermelon used for seeds produced plenty of watermelon flesh,which were not be take good use and causing a huge waste of resources. Wa七ermelon flesh being deep-processing was able to solve this problem and it is an effective way.However,due七o high water content of watermelon, storage intolerance, and harvest time too concentrate,can not annual supply of raw materials,which have seriously hampered the processing and utilization of watermelon.The study七ake breed wa七ermelon as raw material.s, s七udied七he effec七of quick-frozen watermelon and frozen s七orage in different temperatures on the quality of watermelon flesh. By quick frozen and frozen storage, to maintain long一七erm quali七y of fresh watermelon,watermelon can solve anniversary of deep-processing industry of raw materials supply.The study developed a compound watermelon juice drinks,and optimi ze the processes technologies and formulations.Compared to the different Frozen temperature and frozen storage temperature,the results indicate that一30℃frozen under the 120d,and s七ill maintain a good nutri七ional quality and sensory quality(89.7% of lycopene,vitamin C content of 82%,70.2% brightness index).The use of quick-freezing method and frozen storage temperature一30℃,with the 120d,you can ensure tha七七he issue of water storage of raw material s for deep processing of raw materials watermelon to provide technical support to protect.It is feasib Quick-frozen watermelon pulp to produce watermelon juice beverage. The st le for usingudy developed a kind of complex beverage by frozen watermelon pulp, its vitamin C content,bacteriologic index meet the standard and sensory quality was very good with a uniform color, aroma harmony, refreshing taste and satisfy the tastes of the consumers.The study established the formulation and process technology of a copound watermelon drink with passion fruit. The optimized formulation of the watermelon juice was as followed,watermelon juice 60%,passion fruit juice 8%, sugar 6%, citric acid 0.08%; the optimal stabilizer was that the xanthan gum 0.06%,CMC-Na 0.06%,agar 0.04%; sterilization conditions was 85℃for 10min.
