THE PROXIMATE COMPOSITION OF FERMENTED INDIGENOUS COLORED RICE (KHAO-MAK) USING LOOK-PANG FROM INSTANT RICE FLOUR

2021-08-29T13:37:16+07:00

Sweet fermented rice (Khao-Mak) contains a lot of food nutrients. The traditional starter culture (Look-Pang) is composed of yeast, mold and herbs, which are used for fermentation. This research studied the production of Look-Pang by instant rice flour and the proximate composition of Khao-Mak was analyzed. The results showed that the water/flour ratios of 85:100 had a good physical quality. From the analysis of five formulas of Look-Pang mixed with different Thai herbs, it was found that their pH levels, percentages of the total lactic acid, degrees Brix, and percentages of the alcohol content were in the ranges of 3.62-3.70, 0.49-0.54, 34.02-37.71 and 0.55-0.85 respectively. The sensory evaluation was determined by means of 9-point hedonic scales. It was found that the first formula comprising 2.5 g of ginger, galangal, liquorices, garlic each and 0.8 g of black pepper, long pepper each per 100 g of flour had the highest sensory score. Moreover, the black glutinous rice Khao-Mak fermented with pure culture had 36.6 ^oBrix and the alcohol content of 0.4%, the level of which was within the community standard; it also had the highest sensory score. In addition, the proximate composition of black glutinous rice Khao-Mark was higher than Kiaw-ngu glutinous rice Khao-Mak. The results showed that the proximate composition of rice increased after fermentation. In addition, ten colored rice varieties (Oryza sativa L.) were used in this research. The results indicated that the proximate composition was found in all rice varieties. The proximate compositions including carbohydrate, protein, fat, ash, moisture and dietary fiber were around 31.18-38.33%, 3.50-4.87%, 0.07-0.89%, 0.22-0.89%, 53.94-59.10% and 2.02-3.97% (w/w) respectively.

2021-08-29T13:37:39+07:00

The purpose of this research was to study the factors associated with overweight of the students in a university in Phathum Thani Province. The samples were 283 undergraduate students. The data was collected by using the questionnaire. The data were analyzed by using the descriptive statistics including means, percentage, and standard deviation. The correlation among different variables on overweight was calculated with the ratio of weight and height in Body Mass Index (BMI) by using the multiple logistic regressions at the significance level of 0.05. The results of the study revealed that the sample students who lived in dormitories were at a high risk of overweight than the sample students who lived at home at 4.07 times (ORadj = 4.07, 95%CI = 1.59-10.40, and p = 0.003). The samples who did not do exercises were at a higher risk of overweight than the samples who did exercises at 5.03 times (ORadj = 5.03, 95%CI = 2.46-10.27, and p =<0.001). The samples who drink alcohol were at a higher risk of overweight more than the samples who do not drink alcohol at 3.10 times (ORadj =3.10, 95%CI = 1.36-7.06, and p = 0.007). Finally, the samples of the moderate level consumption behavior were at a higher risk of overweight than the samples of the appropriate consumption behavior 6.16 times (ORadj = 6.16, 95%CI = 2.18-17.40, and p < 0.001).

STUDY OF HARMONIC DISTORTION OF OUTPUT CURRENT IN A SINGLE-PHASE BRIDGE CONTROL RECTIFIER WITH A CAPACITOR

2021-09-03T09:41:11+07:00

This article presents the study of the capacitance of a single-phase bridge’s control rectifier by focusing on the harmonic current distortion in the output circuit, the power factor (PF) and the current flow of output which is continuous or discontinuous on the single of simple-phase bridge’s control rectifier.The simulation using OrCAD PSpice can be calculated for the capacitor by reducing 10% of the current in the 2nd harmonic. Then the THD value of the output, PF, together with the flow of the current output would be found continuously. It shows that in case of load which the flow mode is continuous, the reduction in the 2^nd harmonic currents by 50% with , the value of the current deviation of 19.21%, and the factor of 0.401 is the most significant value of this study.
