Addition of rice bran hydrolysate at concentration of 0.25-1.0 % had no effect on overall acceptability of cow milk yogurt but decreased overall acceptability score of soybean yogurt. Optimum concentration of rice bran hydrolysate with high antioxidant activity in cow and soybean milk yogurt was 1.0 and 0.75 %, respectively.

The hot water blanching and steaming pretreatments could reduce brown colour of puffed product. From previous reports, the comparative study of effects of hot water blanching and steaming pretreatments on crisp banana qualities were limited. Therefore, this work was interested in a comparative study of the effects of hot water blanching and steaming pretreatments on crisp banana. The fresh bananas were cross sectional sliced to 2.5 mm and then they were pretreated by hot water or steaming. After that, it was dried by hot air and puffed by hot air. The experimental results showed that both pretreatments by hot water and steaming could reduce the firmness of raw material structure, resulting in the larger volumetric and lower hardness of pretretment product than that of the non-pretreatment banana product. In addition, the both pretreatment also retarded browning reaction of crisp banana product as compared to non-pretreatment product. However, it was not observed the difference in qualities of both pretreatment crisp banana methods. Increasing puffing temperature provided lower hardness of product, however, the color of puffed banana was more browning. Therefore, the banana should be pretreated by hot water blanching or steaming before processing and using of puffing temperature not exceeding 170 oC.","PeriodicalId":426475,"journal":{"name":"ASEAN Journal of Scientific and Technological Reports","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127624368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variables used to study the optimal extraction conditions of total phenolic compounds include concentration of ethanol (10-50 %v/v), extraction time (15-45 min), and ratio of dried pummelo peel: ethanol solution (1:1, 1:2, 1:3). Furthermore, the optimal were determined using a response surface methodology (RSM) by Box Behnken design. The results showed that these three factors affected the yield of extracted total phenolic. Moreover, the statistical analysis provided indications that the data obtained from the experiment should be fitted to polynomial equation because of its high coefficient of determination with R-square = 0.9294. The highest yields of total phenolic compounds were obtained when the samples were dissolved in ethanol at 35%v/v, the extraction time was set at 30 min and the ratio of solid/ethanol was 1:2. Under these optimal conditions, the highest total phenolic compounds yield were 13.67 ± 0.52 mgGAE/gDW from experimental values and 13.66 mgGAE/gDW from predicted values and the scavenging activity of percentage of inhibition by DPPH assay was 32.58 %.","PeriodicalId":426475,"journal":{"name":"ASEAN Journal of Scientific and Technological Reports","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130033008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wind speed at height of 10 m above mean sea level (A.M.S.L.) was measured using SeaWinds Scatterometer on QuickSCAT by NASA. The QuickSCAT satellite images in 1999-2009 with resolution of 1ox1o was interpreted and validated using the measured wind speed provided by the ship observation, buoy data and numerical weather prediction models. The wind speed was interpolated for 1 km resolution enhancement and extrapolated to the height of 50 m A.M.S.L.. The monthly and annual mean wind speed maps were presented in order to show the spatial and temporal variation of offshore wind energy potential. Results showed that QuickSCAT satellite images interpretation gave lower bias in the rage of wind speed of 3-18 m/s, however, the bias was high for wind speed more than 20 m/s. It found that offshore mean wind speed at height of 50 m A.M.S.L. was in the range of 3.0-6.0 m/s where the middle part of Thai offshore had the highest potential with the wind speed in the rage of 7.0-10.0 m/s.
