. This research aimed to study the acidification processes of carving vegetable using acid conditioning machine under emperature and pressure control which was developed in this study. Four acidification procedures were done at normal atmospheric pressure (method 1) under vacuum pressure for 10 (method 2) and 20 min (method 3) and vacuum pressure alternating with normal atmospheric pressure for each of 1 hour. There were two main parts of acid conditioning machine including the temperature controller inside the pickle tank and heat conductor tank and the pressure controller inside the pickle tank. The pickling temperature was stabled at 40oC under the pressure of 0.5 Bar. PLC (Programmable Logic Controller) program was used to write the ladder for controlling all processes and display through SCADA system. The results showed that the acidification method by soaking the carved-rose carrot under vacuum pressure alternating with normal atmospheric pressure showed the shortest time to equilibrium by 7 hours. Then the carved-rose carrot was packed in the glass jar followed by sterilized in boiling water for 15 minutes and stored at room temperature for 7 days. Total bacteria count Escherichia coli and Yeast-mold were not exceeded than the standard limit. Staphylococcus aureus was not detected throughout the storage periods

The objective of this research was to find the suitable processes of carved-vegetables which packed in hermetically sealed container. Two vegetables were composed of carrot and pumpkin. There were carved into rose or leaf shape. An optimum ratio of 2 recipes of pickle solution were studied. The first one was a recipe which acidified with lactic acid (acidified-recipe) to pH <4.6. Another one was a recipe supplemented with preservative (preservative-added recipe). The results showed that an optimum ratio for acidified-recipe was composed of 7.23% vinegar 64.81% water 0.81% salt 27.00% sugar and 0.15% lactic acid which showed the final pH was 3.27. For preservative-added recipe an optimum ratio was composed of 27.03% vinegar 27.03% water 0.9% salt 45.05% sugar and 200 ppm sodium metabisulfite which showed the final pH was 3.39. Carrot pumpkin green papaya and cucumber were sanitized in peroxyacetic acid (80 mg/L 3 min). Radish was dipped in tap water for 3 min. Then all carved-vegetables were immersed in calcium chloride solution (0.5% 2 min) before preserved in acidified-recipe solution in plastic box with a lid and then stored at room temperature for 4 days. Equilibrium time pH and °Brix were studied. The results showed that pH and °Brix were decrease during 4 days storage and showed obviously tended to equilibrium. However carved-radish and cucumber were spoiled by microorganisms as a film on the surface of pickle solution and gas bubble was occurred inside a container on 4 days of the storage. Hence three carved-vegetables including carrot pumpkin and radish were used in the next experiment which preserved in preservative-added recipe. Treatment was compared with the same recipe without preservative as the control. All types of carved-vegetables had an equilibrium time for 7 days. Three parts of samples e.g. pickle solution carved-vegetables and mixed-sample showed pH lower than 4.6 and °Brix were gradually decreased during the storage. Shelf-life of all carved-vegetables stored in hermetically sealed container was up to 7 days. Total bacteria count E. coli yeast-mold were not exceeded than the standard limited by Ministry of Public Health and Staphylococcus aureus was not detected throughout 7 days of the storage.

The research on local wisdom in local Phetchaburi food of elderlies in Ban Huay Sai Nue to transfer and enhance learning capacity through online learning system is both quantitative and qualitative. It aims to collect local wisdom in local Phetchaburi food from both knowledge and direct experience of elderlies in Ban Huay Sai Nue Cha-am City Municipality Phetchaburi province in order to transfer the local wisdom to youths in Ban Huay Sai Nue and nearby areas as well as to develop local food recipe and procedure in both image and video formats through online learning system to enhance learning capacity of youths and other people. The target group was members of elderly group in Ban Huay Sai Nue which was divided into the major target the minor target and the recipents of technology transfer. Tools used in this reearch included a structured interview form and food recipe recording form. The research was divided into 4 main steps: selection of local wisdom collection of local wisdom transfer of local wisdom and distribution of local wisdom. Results of the research show that the target group selected 12 food recipes 8 dessert recipes and 2 drink recipes. The local wisdom was demonstrated by 9 members of elderly group in Ban Huay Sai Nue. The technology was tranferred to 40 students on Tessaban 6 School Ban Huay Sai Nue Cha-am City Municipality. Results of achievement test showed that trainees’ post-training knowledge was significantly diferent from pre-training knowledge at statistical level of 0.05 and satisfaction in the training process was highest in overall.

Fresh coconut syrup is a product from coconut spadix which has unique sweet taste and odor. Due to its short storage life it is usually processed into palm sugar. Development of new product from fresh coconut syrup would add more value by using it to produce crispy jelly. A suitable formula selected as a basic formula used 42.11 percent of refined sugar 56.14 percent of water and 1.75 percent of jelly powder. The basic formula was adjusted by calculating amount of water and soluble solids. Then a study was conducted to determine suitable amount of refined sugar heating period and drying temperature. It was found that a higher ratio of refined sugar and heating period led to increased concentration level of the mixture. As a result the crispy jelly had higher amount of sugar chips on the jellys surface and higher level of hardness. The highest score given by testers was for crispy jelly which used a ratio of fresh coconut syrup and refined sugar at 1:0.6 and 1:0.8 heating period of 5 minutes. Drying crispy jelly at higher temperature resulted in decreased drying period and higher degree of hardness. Drying at 70 degree Celcius produced crispy jelly with good quality which received the highest likeness score from testers. A study that kept crispy jelly in plastic box for at least 8 weeks showed that the tested condition could effectively maintain good quality of the crispy jelly.

This research aims to 1) develop pork roll product from cultivated banana flesh and banana flour for vegetarian food business; 2) develop suitable and unique packaging for food product using cultivated banana flesh and banana flour instead of meat; and 3) transfer technology in developing food product using cultivated banana flesh and banana flour instead of meat for vegetarian food business. Regarding suitable amount of banana flour used in place of isolated soy protein in pre-emulsion preparation from 4 levels of banana flour used at 0 10 15 and 20 percent it was found that increasing amount of banana flour used in place of isolated soy protein caused significant increase of L* value in the product (p<0.05). Moreover hardness and flexibility in texture profile of the product were not significantly different from the control product (p>0.05). In terms of sensory evaluation tasters gave the highest score for meat-emulated reducedemulsion product that used banana flour in place of isolated soy protein at 15 percent. For packaging of pork roll product it was found that Model-A package was the most suitable with recommendations to add tight-closed material to prevent contamination from outside and to print expiry date as well as food safety certified sign. Furthermore consumers’ overall satisfactory in packaging model was found to be highest at the mean of 4.31. Finally transferring of technology in a form of training workshop in developing food product from banana flour for vegetarian food business for Ban Lak Khon Bakery Housewife Community Enterprise and entrepreneurs in Nonthaburi province showed that post-training test scores were significantly higher than pre-training scores at .05 level. This indicated that technological transfer in a form of real-practice workshop provided increasing knowledge in developing food product from banana flour for vegetarian food business. Moreover it was also found that trainees were highly satisfied in both overall service (mean of 4.85) and by-aspect: servicing staff (4.93) procedure/steps (4.87) trainers (4.83) and usefulness of service (4.75) respectively.
