The study of vegetable-carved processing packed in hermetically sealed container for 5 types of plant e.g. carrot pumpkin radish green papaya and cucumber which carved into rose or leave shape and preserved in acidified-pickle (7.23% vinegar 64.81% water 0.81% salt 27.00% sugar and 0.15% lactic acid pH 3.27). The processing were conducted by sanitized carved-carrot pumpkin and radish in peroxyacetic acid solution (80 mg/l 3 min) or dipped in tap water (3 min) for green papaya and cucumber. Then all carved-vegetables were blanched in calcium chloride solution (0.5% 3 min) followed by preserved in acidified-pickle in plastic box with a lid and stored for 4 days at room temperature (25ºC). The results showed that pH and °Brix decreased 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 4th days of the storage. Hence carrot and pumpkin were used in the next experiment which preserved in preservative-added recipe (27.03% vinegar 27.03% water 0.9% salt 45.05% sugar and 200 ppm sodium metabisulfite pH 3.39) with hot-filled method in glass bottle. Treatment was compared with carved-vegetables preserved in acidified-pickle and kept at 4oC as the control. The pH of samples of pickle solution carved-vegetables and mixed-sample of both treatments showed lower than 4.6 and °Brix were gradually decreased during storage periods.The appearance of both treatments were maintain good and not different between treatments. Shelf-life of carved-carrot -pumpkin and -radish stored in hermetically sealed container was up to 7 days. Total bacteria count Escherichia coli yeast-molds were not exceeded than the standard limited by Ministry of Public Health and Staphylococcus aureus was not detected

The research aimed to analyze and compare contents of accumulated residue of chlorpyrifos chromium lead and cadmium in five varieties of vegetables in Loei River Loei Province. Five varieties of vegetables such as Vegetable fern (Diplazium esculentum Limnocharis flava (L.)) Limnocharis flava (L.) Buch Lasia spinosa (L.) Thwaites swamp cabbge (Ipomoea aquatica Forsk) and water mimosa (Neptunia oleracea Lour.) were collected during winter summer and rainy seasons from Phu Luang Mueang Loei and Chiang Khan District. Chlorpyrifos was analyzed by high performance liquid chromatography (HPLC). The results showed that the highest chlorpyrifos contents were found in vegetables in winter and summer season in the amount of 0.04±0.00 mg/kg. Analysis of all three heavy metals were carried out dry ashing at 500C and acid digestion with nitric acid prior to analyzing by flame atomic absorption spectrophotometry (FAAS). The results showed that cadmium accumulation in the highest content among all metals in water mimosa (Neptunia oleracea Lour.) in summer season from Phu Luang District (1.83±0.01 mg/kg). The second highest metal content was lead which has found in swamp cabbge (Ipomoea aquatica Forsk) in summer from Mueang Loei District (1.40±0.08 mg/kg). chromium showed the lowest content in Limnocharis flava (L.) Buch in winter from Mueang Loei District (0.47±0.04 mg/kg). The contents of chlorpyrifos and heavy metals were not exceed the legal limits set by International Standard Food and Ministry of Republic Health No.98 of Thailand except Ipomoea aquatica Forsk which collected in summer that showed the lead content higher than the legal limits.

The biosorption of Rhodamine B using modified water hyacinth roots was studied. The adsorption experiments were conducted in a batch setup. Parameters affecting the adsorption of Rhodamine B including pH of a solution adsorption time adsorbent dose and dyes concentration were investigated. With the 80 mg/L Rhodamine B solution of pH 6.0 adsorption time of 60 min and 0.10 g of modified water hyacinth roots the kinetic models pseudo-first order and pseudo-second order kinetic model were applied to examine the kinetic adsorption. The adsorption kinetic data correlates with pseudo-second order kinetic model. The Langmuir and Freundlich adsorption models were applied to describe the isotherms and isotherm constants. Adsorption isotherm data correlates with Langmuir adsorption model. The maximum adsorption capacity of modified water hyacinth roots for Rhodamine B was found to be 63 mg/g

The purpose of the qualitative study was to seek for on guidelines for increasing productivity of organic products (vegetables) of Thamsua community members in Kaeng Krachan Phetchaburi Province. Data collection was done through observation interview and document analysis. The samples were 10 leaders and members of Organic Product Division of Thamsua Community in Kaeng Krachan Phetchaburi. The research results revealed that problems and obstacles in increasing the organic product were the lack of worker and continuity to produce goods for distributing to meet the market demand. The solution could be done by increasingly distributing products the surrounding communities to meet the needs and quality control standard of the market. In terms of the management the community should have a clear management plan and appoint a committee to co-ordinate its policies plans regulations and management. They could invite other members from neighboring communities to be involved. As for the solutions for the production and product diversification external agencies might be asked to participate in the productivity enhancement such as public or private sectors and educational institutions for example. The government might be in charge of supporting for career development and income private sectors for more marketing channels while educational institutions might support for knowledge needed for increasing the productivity. Concerning marketing solutions for more distribution channels online marketing should be set up by coordinating with private sectors to provide additional distribution channels such as organizing product display booths with public and private sectors. Financial and accounting solutions for the lack of management funding sources should be organized through the community savings such as the Cooperative Community Enterprise or Provincial Cooperative office to e involved in accounting management to create systematic financial management.

The purpose of this research Knowledge Management Marketing and Business Plan.for Manufacturers Hyacinth Wickerwork OTOP in Central Area is to study the implementation of marketing and business plan for OTOP producers from water hyacinth in North Central Area and to develop the model operations marketing and business plan to effectively comply with the business of manufacturing OTOP products from hyacinth wickerwork. The questionnaire to collect data are 180 samples of producers OTOP from hyacinth wickerwork in North Central Area where 4 provinces is Ayutthaya Ang Thong Sing Buri and Chai Nat. the data were analyzed by the statistics program for data analysis were percentage mean standard deviation and T-Test Independent test and F-Test. 1. The results of data analysis from the 180 samples found that most of them are female. Their aged between 35-65 years as a housewife or a farm garden who residing in the same neighborhood and to be relatives. For weaving water hyacinth is a hobby or an extra income when the availability of routine and trained by a professional instructor.The material is produced in the canals which are obtained locally. 2. The results of the data analysis on the marketing knowledge that the samples who produce OTOP by hyacinth wickerwork do not understand or have on in knowledge of the market because of they are production only. They recognize only the original knowledge and understanding of the raw materials whish used hyacinths is to be processed only. 3. The results of the data analysis on the business plan showed that this group with expertise in the preparation of business plans by training from the Department of Community Development by understanding the basics of a business plan that must do more to save a local guide and a business planning system and also that a standard can be used in contact with various Financial Institutions Officers but the leader of the group also a lack of understanding of the details of the business plan accuracy therefore it does not convey such knowledge to a group of people or their next generation. The results of the researchers found that 1. The difference of Gender position and experience can impact the implementation of marketing and business plan also knowledge and understanding are different. 2. Although cultural technologies competitive conditions government policies legal and resources naturally are different but the producers from water hyacinth in North Central Area can also develop a model for implementation of marketing and business plan to be effective as standard and can be used to benefit the situation is different.
