This research had the following objectives: 1) To compare roasted and fried Sangyod rice grain products. 2) To find proper proportion of puffed Sangyod rice grains to other seeds. 3) To find storage life of puffed Sangyod rice grains mixed with other seeds product. 4) To calculate cost of production of oil free puffed Sangyod rice grains mixed with other seeds product. Results found that physical properties of roasted Sangyod rice grains puffed and expand better than the fried ones. Consumers preferred the roasted grains to the fried oned because less oil was consumed which was good for health. In developing puffed Sangyod rice grain product Consumers accepted the second formular of 50:50 proportion of puffed Sangyod rice grains to other seeds better than the other proportion of 30:70 and 70:30. The results were statistically significant. This formular was used in storage life study. Results found that the product can be kept 7 days at ordinary room temperature Microbial growth was observed every two days. Mold and yeast counts and water activity were studied. No mold nor yeast were found in day 0 water ativity was 0.58. No mold nor yeast were found for 7 days. Cost of production of puffed Sangyod rice grain mixed with other seeds product was calculated. The material cost was 95 Bahts. 30% processing codt was 29 Bahts for 50 pieces of product. The average cost per piece was 2.10 Bahts.

The objective of this study was to investigate the optimal formulation of mulberry fruit leather product when varying the weight ratio of mulberry fruit: water as 70:30 60:4050:50 40:60 and 30:70. Three factors were then determined by simplex centroid design; sugar (0-100% or 0-50 grams) citric acid (0-100% or 0-5 grams) and pectin (0-100% or 0-3 grams) which the sum of them equivalent to 100% while other ingredients remained constant. Analysis of the data was performed using ANOVA and Mixture Response Surface Models. The results indicated that the highest adhesiveness force and gumminess of mulberry fruit leather product were founded when the weight ratio of mulberry fruit to water was 70:30. The amount of sugar acid and pectin had effects on water activity (Aw) texture profile and sensory score of overall liking of product. From contour plot the predictive models were obtained by plottin g the contour line of all sensory attributes with acceptable score greater than 5.5 and thus the optimization area was selected. After overlapping contour plots an optimal formulation obtained was composed of 40-70% sugar 0-5% citric acid and 30-55% pectin. The sensory score of overall liking of product using a 9-point hedonic scale was 6.3. The water activity (Aw)adhesiveness force cohesiveness and gumminess of the prototype mulberry fruit leather product was 4.9 945.11 g. sec. 0.85 N and 452.12 N. respectively.

The objective of this research was to develop a beverage product from broken-milled sangyod rice for the elderly person. Raw materials of this product were broken-milled Dangyod rice soybean red kidney bean Job’s tears sesame and sucrose. The highest acceptance score (9-point hedonic scale) by the panelist who the elderly person ( 60 years old) showed that 7% broken-milled sangyod rice was proper for supplement in this beverage ( 0.05). The color in tem of L a and b values were 64.80+ 0.04 6.60+0.07 and 8.27+0.05 respectively. Viscosity of this beverage was increased by addition of broken-milled Sangyod rice. The B brand sweetener was gained the highest acceptance score. The developed product was 21.19 kcal/100g and fat protein fiber and carbohydrate content were 0.59% 1.25% 0.15% amd 2.75 % respectively. After storage at 4+ C for 15 days this product was shown to be safe for consumption. It passed quality criteria of Thai community product standard (TCPS 282/2015). The 100 elderly consumers focused on the nature of rice or cereal products in terms of health benefits. All of consumers were accepted on the product for beneficial for health.
