The objective of this research is to study and find the relationship between Role Perception of conservation Fruits and Vegetable Carving with individual variables including gender educational level and experiences of fruits and vegetable carving Contributing factor including knowledge of fruit and vegetable carving Opinion towards fruit and vegetable carving and participating in fruit and vegetable carvings conservation activities. The research sample were randomly selected 249 of Bachelors degree students of Home Economics Technology Faculty from Rajamangala University of Technology Phra Nakorn Rajamangala University of Technology Krungthep and Rajamangala University of Technology Thanyaburi. The research methods were questionnaires and collected data were analyzed by using descriptive and inferential statistics. The study found that The Role Perception of conservation Fruits and Vegetable Carving is at high level The opinion towards fruit and vegetable carving and participating in fruit and vegetable carvings conservation activities is in relation to The Role Perception of conservation Fruits and Vegetable Carving The Statistically significant were at a level of 0.05. The knowledge of fruit and vegetable carving was not related to The Role Perception of conservation Fruits and Vegetable Carving.
การพัฒนาหลักสูตรวิชาชีพเฉพาะทาง เรื่องการแกะสลักผักและผลไม้
The purpose of this research aimed to 1) study the basic data for the development of specialized professional course on vegetable and fruit carving 2) design and examine the quality of specialized profession course on vegetable and fruit carving 3) try out specialized profession course on vegetable and fruit carving and 4) improve and revise specialized profession course on vegetable and fruit carving. The samples were 3 key respondents and 20 attendees. The instruments included an indepth interview form and evaluation form. The data was analyzed by descriptive and inferential statistics. The findings revealed that the current patterns used for teaching carving (2019) included fruits for consumption perforated leaves grooved leaves closed-carpel roses dahlia zinnia and plumeria for decoration and food works. The most popular kinds of vegetables and fruits for carving were cantaloupes long cucumbers and carrots. The most popular pattern was rose. The duration for vegetable and fruit carving per 1 piece was 5 minutes. The results of course design and quality examination showed the highest IOC (0.82). For course try-out the values of evaluator confidence index came out as follows i.e. RAI of Unit Plan 1 = 0.85 RAI of Unit Plan 2 = 0.94 RAI of Unit Plan 3 = 0.92 RAI of Unit Plan 4 = 0.89 RAI of Unit Plan 5 time 1 = 0.82 and RAI of Unit Plan 5 time 2 = 0.79; implying that skill evaluation action and carvings went in the same direction.

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.

Quality control of dyeing and finishing of Water Hyacinth yarns and their transformed materials for commercial was a main objective to establish the dye database of synthetic dye and natural dye. The dye database was a data for quality control in dyeing process of raw material as Water Hyacinth yarns also it resolved the un-repeatability dyeing problem. Reactive dye was used for synthetic dye database creation on dry Water Hyacinth yarns at 80oC for 30 minutes. Red as Hicion Red He-3B yellow as Hicion Yellow HE-4RN Blue as Hicion Navy Blue HER 150% and black as Hifix Black KNN were the represent synthetic dye and Sodim sulphate 20 g/l and sodium carbo nate 20 g/l were used as auxiliaries. The other hands the natural dye database was forming from Ebony tree Caesalpinia sappan and Turmeric. They were dye on dry Water Hyacinth yarns at 80oC for 30 minutes and Sodim sulphate 20 g/l was the auxiliary. Whereas Butterfly pea were dye at 80oC for 30 minutes by Sodim sulphate 20 g/l and sodium carbonate 20 g/l were the auxiliaries. The whole dye database was defined the totally in Primary Secondary and ternary dye cycle. The transfer knowledge was distributed to the enterprise at Nakhon Prathom Provincd as “Chumchonjaksanpaktobchawha Bann klongnokkratum”. The topics were “How to establish the synthetic and natural dye database” “Water repel lent finishing” and “developed and transformed the Water Hyacinth to products”. The target group was very satisfied in this topic as 4.39. In the result the proportion between economic and social factor by the income increasing in 1 year was 5.04. So the research project was achievement.

The research team has isolated the cellulase producing microorganisms which have capability in producing extracellular cellulase enzyme for cellulosic degradation from leftover agricultural waste materials such as fruits and vegetables. After cellulosic material degradation the products mainly were sugar moiety being the starting materials for further alcohol fermentation and/or possibly being used in cultivation of common microorganisms. In the study when different 49 bacterial isolates were tested for their cellulase activity on Carboxymethyl cellulose (CMC) two bacteria Bacillus spp. CE08 and 49 were selected due to high cellulase activity and thus tested for the physical and chemical properties. Their 16S rDNA sequence comparisons were close to Bacillus sp. isolate obtained from the soil. Both isolates are common aerobic/facultative aerobic bacteria with the length of 1-3 μm Gram positive and preferring the fermentation of maltose and xylose to glucose while minimal degradation on sucrose and lactose contents. Their optimum digestibility was at 40°C pH 4.5 for the broth having unpurified extracellular cellulase activity at 3-4 μg /mg. The enzyme could use the substrateCMC the best but rice straw more slowly but better than grass. However the enzyme displayed the least digestion effectiveness on cotton. Both of these isolates are expectedly applied in the biological degradation process substituting chemicals that cause pollution problems to the environment. Additionally this is one promise way to bring value of agricultural waste to the community.
