This research presents the processing of fresh guava into guava juice product. to be kept for consumption and distribution in the local area It is an alternative career path that helps rural farmers earn more. and create additional careers for the family But farmers still lack the correct technology tools and processing methods in each production process. Therefore there was a problem of insufficient cleanliness taking a lot of time resulting in unacceptable quality and the production is low the postharvest engineering research group has conducted research to find suitable guava juicer. This study is based on working principles of food processing equipment in general use. Come as a guideline to develop improve and create prototypes. The original guava juicer was a grater roller squeezer. There is a guava-sized subsystem consisting of a sub-chamber with grated rollers and the waste water barrier system consists of a juice sieve chamber a waste separation room a spiral conveyer and a sweeper set. various parts that come in contact with the guava juice is made of stainless steel The power source uses a 1-horsepower electric motor a single-phase electrical system a voltage of 220 volts. The machine has the ability to block water at a rate of 250 kg / hour. The juice obtained must be filtered out again with a centrifugal bag filter capable of filtering water at a rate of 50 liters/hour. The prototype guava juice machine costs 40000 baht and the centrifugal filter bag costs 5000 baht. With just one such machine each of these machines can produce 28000 liters of guava juice/year (112000 bottles a year) able to get a return in 0.08 years with an average processing cost of 4.48 baht/bottle which is appropriate in engineering economics. In investment use a ready-to-drink guava juice machine. Fresh guava ingredients are available throughout the year and have 200 business days/year.

This aims of special project are study about method reduce astringent of ripening suitable products of carunda pasteurized juice we are study the changes during storage of carunda pasteurized juice and study cosumer acceptance of products of carunda pasteurized juice. From method revealed that the methods of ripening carunda the most suitable method is method 3 the method of ripening Cassia Tree in 3 days we are found physical quality in the value L* a* and b* (peel) is equal to 38.03±0.26 29.44±0.17 13.43±0.35 the value L* a* and b* (the meat) is equal to 35.43±0.10 36.86±0.08 19.87±0.07 Chemical found °Brix values were 8.83±0.29 and 2.97±0.02. The pH of the test scores in most aspects. The difference was statistically significant (p<0.05) and then study the dynamics between the preservation of products carunda pasteurized juice and found that L* a* decreased statistically significantly (p<0.05) and b* values were increased statistically significantly (p<0.05). The bacteriological quality of carunda pasteurized juice found that microorganisms not exceed 1x104 cfu/sample 1 ml yeast andmold must not exceed 100 CFU/sample 1 ml S. Cheryl Shea coli must be less than 3 MPN/sample 1 ml and Coliform less than 2.2 MPN/100 ml Which does not exceed the prescribed standards of the Ministry of Health. Can be stored at room temperature 4+2 °c storage for 3 weeks The study on the adoption products Karanda Pasteurized found that consumers agree 100 percent.

The purpose of the study of processed fruit products from Karonda : Bang Nok Kwaek parish communities Bang Khonthi Samut Songkhram Province is to study the proper quantity of the Koranda fruit in the product the quality in the product’s process and the consumers’ acceptance (Consumer Test) in the product. The processed products are Karonda fruit jelly instant pasteurized Karonda fruit juice with extra fiber Karonda fruit sorbet Karonda fruit yoghurt ice-cream and concentrated juice (sauce) for drink mixing.

Result showed that the optimum ratio of mango pulp to water was 1:2. The mango juice contain of malic tartaric citric succinic and ascorbic acid at 0.005 0.053 0.180 0.005 and 0.138% respectively. The selected juice had 3.49 12.20oBrix 62.25 7.71 59.24 and 5.26 micrograms per gram of pH total soluble solids L * a * b * color values and beta-carotene content respectively. Sensory evaluation result revealed that the selected mango juice was accepted by 30 panelists which was medium like in color appearance odor taste and overall acceptability. Result of consumer test had shown that 97 % of 100 consumers from Lampang province were accepted and 65 % decided to buy the product.
