The results of the study showed that the suitable condition for malt production as follows: wheat was washed in anolyte solution pH , then soaked in catolyte solution at 25oC to reach moisture of 40-43% and germinated at 20oC/ 96-104h, the diastase activity was highest. Paddy was washed in anolyte solution, soaked in catolyte solution at 25oC, then germinated at 25oC/ 130h in catolyte solution. | Journal of Science & Technology 126 (2018) 026-031 Effects of Electrochemical Activated Water During Germination on Moisture and Diastase Activities of Germinated Wheat and Paddy Nguyen Van Hung*, Tran Hong Anh, Vu Thi Tho Hanoi University of Science and Technology – No. 1, Dai Co Viet Str., Hai Ba Trung, Ha Noi, Viet Nam Received: January 22, 2018; Accepted: June 25, 2018 Abstract Electrochemical Activated (EA) Water has been studied and applied in many fields such as medicine, agriculture and food. Using anolyte solution pH for disinfection allows to reduce the microorganism contamination. Catolyte solution pH was used for soaking grains and replenishing moisture during germination. Grains were soaked at temperatures of 20, 25, 30oC to reach a moisture content of 40-43%. Study germination at 15, 20, 25 oC for 4 to 6 days. Determining suitable regimen for harvesting wheat malt and paddy malt using electrochemical activated water solution, is to soak grains at 25 oC and grains germination at 20oC and paddy grains soak and germination at 25oC. The results of the study showed that the suitable condition for malt production as follows: wheat was washed in anolyte solution pH , then soaked in catolyte solution at 25oC to reach moisture of 40-43% and germinated at 20oC/ 96-104h, the diastase activity was highest. Paddy was washed in anolyte solution, soaked in catolyte solution at 25oC, then germinated at 25oC/ 130h in catolyte solution.

Introduction* countries around the world because of their environmentally friendly solutions [8, 19, 20, 23] to improve product quality, positive effects in malt production with low cost of energy [8, 14, 19]. Anolyte water has a pH of and a reduction in oxidation potentials of +450 to +850 which presented bactericidal property [9, 10, 16]. The catholyte solution has a pH of to and a reduction in oxidation potential .
