The objective of this research is to study the suitable production process in the production of Pad Thai sauce Crispy rice noodle sauce (Mee krob) and three mixed flavors sauce (Sam-rod) by using pineapples juice as the main ingredient. To study the quality of this finished three sauce products from pineapples. And to study the consumer test of pineapple sauce products. The results of the development of a suitable recipe for Pad Thai sauce production. From the evaluation of the sensory quality of Pad Thai sauce (9 points Hedonic scale). It was found that panelist accepted the appropriate amount of pineapple juice in the production of Pad Thai sauce at 30 % in all attributes in terms of appearance color smell taste texture and overall liking with an average score of 8.08 7.83 7.93 8.15 8.05 and 8.13 respectively which was at a high level of preference. Sensory evaluation of crispy rice noodle it was found that 75% of pineapples accepted for the source production in terms of appearance color smell taste texture and overall liking. With an average score of 7.89 7.79 7.88 8.03 7.98 and 7.93 respectively which are in the high level. Sensory evaluation of three mixed flavor sauce. It was found that panelist accepted 100 % pineapple sauce using pineapple juice in terms of appearance color aroma taste texture and overall liking. With an average score of 8.35 8.04 8.25 8.22 8.15 and 8.24 respectively which is in the high level. The results of the study of the quality of Pad Thai sauce crispy rice noodle sauce and mixed three flavors sauce that use pineapple juice as the main ingredient found that increasing the amount of pineapple juice affects the pH value of the products. All 3 types of sauce with the pH value are in the acid range. The microbial quality of all 3 types of sauces has passed the standard of community product standards set by the Ministry of Industry. The results of the consumer test on pineapple sauce products. The majority of consumers are female. Most of them are between 19-29 years old and in the age of 40-49 years.

Abstract Milk ice cream is the one of most popular dessert in many countries. But the most milk ice cream contain high amounts of sugar and fat. It is for this reason that consumers who exercise regularly concern about the impact of ice cream consumption on health and have led to a considerable rise in high protein and low sugar ice cream demand for this consumer group. Therefore the objective of this study was to develop the reduced energy milk ice cream by using chicken breast and inulin. Milk ice cream was supplemented with chicken breast at 5 10 and 15% by total weight. The result showed that 10% chicken breast ice cream was highest score of sensory evaluation. Sugar was substituted with inulin at 25 50 and 75% by weight. The result showed that the replacement of sugar with 50% inulin was suitable for ice cream. The chicken breast ice cream with inulin formula were determined the physical properties. The result showed that viscosity overrun texture and melting rate of the developed formula were 147 cps 41% 11780 g force and 6% respectively. The lightness (L*) redness (a*) and yellowness (b*) value were 88.68 4.60 and 19.11 respectively. The proximate compositions moisture and protein content of the chicken breast ice cream with inulin formula were 68.03 and 11.79% higher than basic formula whereas fat and ash content of the chicken breast ice cream with inulin formula were 6.02 and 0.45% lower than basic formula. Microbiological quality of the chicken breast ice cream with inulin formula were in the acceptable limit according to Notification of the Ministry of Public Health. In addition the total energy of the chicken breast ice cream with inulin formula was lower than basic formula. The cost of the chicken breast ice cream with inulin formula was higher than basic formula at 16.23%.

The main objective of the study was to understand image perception of the sample groups of 840 people towards Rajamangala University of Technology Phra Nakhon. The sample groups included the general public and high school students. The method for collecting data was the questionnaire survey. Rajamangala University of Technology Phra Nakhon is known among student and general public. Students knew it as a university while the general public knew it as a vocational college. Thirdly the outstanding perception of the institution among the students was in good academic level (mean=3.60). The highest perception score was about the schooling system (mean=3.60). The general public perceives more in details about its admission system (mean=3.52) and had good perception towards the institution’s good image (mean=3.52). Furthermore online media played a significant role in transferring information and creating the image of the institution among the sample group (mean =3.52 from student and 3.35 from general people). Fifth result gender did not play a significant role in perceiving the image of the institution. The last result was that gender played a statistically significant mark by .01 in media exposure among general public. In conclusion there is no distinctive difference between students and general public in having image perception towards Rajamangala University of Technology Phra Nakhon.
