This research aims to study the appropriate drying condition and extraction solvent for extracting protein and antioxidants from the porcine placenta. Three levels of drying temperature were used in this study which were 50 60 and 70ºC the result shows that the best drying condition for porcine placenta was 70ºC for 4 hours because this condition provided the least drying time and the lowest moisture content of porcine placenta (3.80±3.36% dry basis). After that the fresh and dried porcine placenta were extracted by using three solvents which were deionized water (DI) phosphate buffered saline (PBS) and hexane. The efficiency of extraction was investigated by measuring the crude protein and antioxidant of the porcine placenta. It was found that there was no protein and antioxidant in fresh and dried porcine placenta extracted by hexane. However the protein was found as 0.05±0.01 and 0.04±0.01 mg of bovine serum albumin/100 mg fresh for fresh porcine placenta and 0.12±0.030 and 0.07±0.016 mg of bovine serum albumin/100 mg fresh for dried porcine placenta extracted by DI and PBS respectively. In additional the antioxidant was found as 1.13±0.03 and 1.29±0.04 mg of trolox/100 mg fresh for fresh porcine placenta and 3.37±0.02 and 3.59±0.01 mg of trolox/100 mg fresh for dried porcine placenta extracted using DI and PBS respectively.

Proteolysis and lipid oxidation during ‘mu som’ fermentation as affected by different ratios of white and black glutinous rice
Proteolysis and lipid oxidation during ‘mu som’ fermentation as affected by different ratios of white and black glutinous rice

Changes in muscle protein proteolysis and lipid oxidation of ‘Mu Som’ added with different white and black glutinous rice ratios (w:w) at 100:0 (W100) 75:25 (W75B25) 50:50 (W50B50) 25:75 (W25B75) and 0:100 (B100) during 72 h fermentation at 30°C were investigated. During 36 h fermentation B100 exhibited a higher rate of fermentation than others as indicated by lowered pH and lactic acid production (p<0.05). Due to higher acid production rate the proteolysis of muscle proteins as evidenced by the increase in trichloroacetic acid (TCA)-soluble peptides and smaller molecular weight of proteins appeared as electrophoresis were more pronounced. These might contributed to higher released water and expressible water as well as pale color. Higher black glutinous tice higher released water and expressible water were observed. The lipid oxidation in all samples was observed during fermentation. All samples had no difference in likeness scores of all attributes (p>0.05). From the results the ratio of white and black glutinous rice might contribute to proteolysis which effected on released water of Mu Som.

Drying kinetics model of fermented soybean meal using hot air-drying
Drying kinetics model of fermented soybean meal using hot air-drying

The aim of this research was to model the hot air-drying (HAD) of fermented soybean meal (FSBM) containing probiotic Enterococcus faecium . The HAD was performed to reduce the moisture content of the FSBM. The effects of drying temperature on cell viability and moisture content were investigated. Moisture content decreased rapidly with increasing drying temperature. This probiotic strain’s cell viability slightly decreased at drying temperatures lower than 50°C and was greatly decreased at 55°C. Four mathematical models were applied to describe its drying kinetics revealing that the Page model was the best fit for characterizing the drying kinetics during drying of FSBM with a coefficient of determination (R2) of 0.9996. Moreover the Page model provided the lowest root mean square error (RSME) and chi-square (X2) and the highest modeling efficiency

The Chabot application aims to promote Ecotourism in Bang Phae District Ratchaburi. The application has been developed by modern information technologies such as Artificial Intelligence (AI) and Natural Language Processing (NLP) via Dialogflow program and LINE application. The application consists of three main components: User interface Entities and Fulfillment engine and Intent. A usability test was conducted to evaluate the user experience in terms of effectiveness efficiency and satisfaction with which participants perform tasks when using the application. Consequently the participants were asked to complete the survey. The result shows that the overall user satisfaction score remains high (x̅ = 3.80). However the ability to communicate effectively scored lowest (x̅ = 3.66)
