The Processing Technology Research Of Seed Melon Juice Products

Seed melon is a a kind of watermelon varieties that also known as "a kind of watermelon". It is famous of its full of seed and take it by punching. The harvests are discarded after seeds was taken out. It lead to serious waste of resources and environment pollution. In order to make full use of the abandoned resource,this topic study the processing technic of its Concentrated Juice, Clarified beverage and Corrupt beverage.The main experimental results are as follows:1.Seed melon concentrate juice processing process study is divided into three parts: Browning prevention, Enzyme treatment and stability study. Comparing the effectiveness of color-protection of different reagent, 0.05% citric acid and 0.1%ascorbic acid was been chossen.The best conditions of enzyme treatment : enzyme added is 0.15%(0.1% pectinase, cellulase 0.05%.), enzymolysis temperature 50 ℃,enzymolysis time 2 h, enzyme solution PH = 4.5; Using high-speed centrifuge for a kind of seed melon concentrate juice for clarification, centrifuge speed of 10000 r/min for 10 min would be the best. On this condition.the colour of seed melon concentrate juice is light yellow, a better translucency, fine and uniformly distributed organization status, no visible impurities, a kind of watermelon juice concentrate.2..Seed melon concentrate juice, on average, juice yield was 79.74%, the Absorbance value was 7.2, transmittance was 94%; the soluble solids content was14.3%, total acid is 2.5 g / 100 g, the total number of bacteria was 58 / ml, the number of e. coli was 3/100 ml, bacteria is not checked out.3. The process of seed melon juice beverage, seed melon juice concentrate dosage was 20%, sucrose dosage was 6%, citric acid dosage was 0.3%. The soluble solids content of product was 9%, total acid is 1 g / 100 g, the total number of bacteria was 54 / ml, the number of e. coli was 3/100 ml, bacteria is not checked out.4. Seed melon cloudy juice during processing, seed melon juice consumption is40%, the dosage of sucrose was 7%, the dosage of citric acid was 0.08%, the compound of stabilizers xanthan gum + CMC Na dosage was 0.15%.The soluble solids content of product was 12%, total acid is 1.8 g / 100 g, the total number of bacteria was 39 / ml, the number of e. coli was 1/100 ml, bacteria is not checked out.
