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.

The purpose of this study was to optimize the formula of cereal drink. Ninetyoneto ninety-three percent of red kidney bean three to five percent of peanut andone to three percent of Job’s tear were studied by using Mixture experimental design(Scheffe’ simplex-centroid design) to determined the optimumformula. Chemical and physical properties %protein pH and total soluble solid were analyzed. The result shown the formula of cereal drink consisted of 0.5% red kidney bean 1% peanut and 1%Job’s tear were the optimum formula. The optimum product was evaluated color(L* a* b*) pH %protein %fat and %fiber. The product consisted of L*38.20 a*0.13 b*3.46 pH 6.6 1.3% of protein 0.2% of fat and 0.02% of fiber. Coliform bacterials was less than 3.0 MPN/100ml. Sensory evaluation was tested by 100 panelists using 9-point hedonic scale in aspects of color odor flavor texture and overall liking were 6.18 6.16 6.09 6.04 and 6.63 respectively. The overall liking of product was within the range of like slightly

This research on product development of beverage from Riceberry plus protein was aimed to 1) develop the formulation of beverage from Riceberry 2) study the appropriate ratio of beverage from Riceberry to instant protein content 3) study the appropriate ratio of beverage from Riceberry plus protein to sugar content 4) study the quality change of storage. Samples used in this study were personnel of nutrition service division Central Chest Institute of Thailand among 30 samples. Sensory evaluation was carried out using the acceptance scores on appearance color smelling viscousness smoothness overall preference (5- point hedonic scale). Data were analyzed by using mean and standard deviation. To study mean comparison analysis was used. This research revealed that the best formulated beverage from Riceberry plus protein contains Riceberry 200 gm. water 1800 ml. instant protein 54 gm. and sugar 90 gm. This appearance is clearly violet rich Riceberry and soybean smell and sweet with sugar. The acceptance scores on appearance color smelling viscousness smoothness overall preference were 3.93 3.80 3.03 3.23 3.40 and 3.17 respectively that mean like moderately. The study of changes in the physical revealed that beverage could be kept for 1-3 days at the temperature of 7˚C.

The objectives of this study were to (1) evaluate physical and chemical properties of the commercial beverages from fruit and vegetable extracts (2) develop a beverage from butterfly pea and roselle extracts (3) analyze the shelf-life of this product and (4) determinate the consumer acceptance of the beverage from extracts of butterfly pea and roselle. The findings showed that the commercial beverages from fruit and vegetable extracts were clear and dark brown color 3.43-3.67 (pH) 16.50-35.00°Brix (total soluble solids) and low anthocyanin content. The optimum extraction of butterfly pea and roselle was boiling at 70+2°C and evaporation at vacuum pressure (72 millibar). This process resulted in the final anthocyanin content approximately 1366.98 and 4090.19 mg/l for butterfly pea and roselle extracts respectively. Then the butterfly pea and the roselle extracts were blended at various ratios. Based on sensory evaluators (n=50) the 50:50 blend was the most preferential with respect to overall acceptability (p≤0.05). The decrease in the anthocyanin content was observed during storage for 5 weeks. No Coliform bacteria E. coli Salmonella spp. and yeast and mould were found in all samples while the total plate counts were still accepted asconsidered for the standard set by the Ministry of Public Health. An acceptance test showed that consumers (n=100) absolutely accepted this product.

Khao’ Niao Dam is a grain which has anthocyanins pigment. Rice flours contained high protein content more than white grain and have higher water absorption. The white rice flour had higher swelling power and lower solubility than 6 rices flours. Amylose which content in the white rice flour is peak viscosity final viscosity setback and pasting temperature than the waxy rice flours. The objectives of this research were to formulate and determine the appropriate condition for sensory test on the rices powdered beverage products to consumers in terms of color flavor sweet taste viscosity and preference overall. Starting from the basic formula 3 formula is a formula that consists of Germinated brown rice drying were 23.33 % millet drying were 3.33% soybean powder were 6.67% powdered milk were 13.33% sugar were 33.33 % and cream powder were 20.00%. Acceptance scores of 7.60 and then to research the use of Germinated brown rice drying a substitute for cream powder in the manufacture of rice powder beverages into 3 levels such as 50 75 and 100% the amount of Germinated brown rice drying a substitute for cream powder 100 % has been the most acceptance. Then the ratio of rice flour 7 the appropriate type of beverage rice powdodor and viscosity of the beverage rice powder for 3 formulas were formulated with Black Glutinous flour were 10.00% the most acceptance. The study of soybean powder substitute millet powder in the manufacture of rice powder beverages to reduce the viscosity into 3 levels: 50 75 and 100%. The result showed that the suitable of soybean powder substitute millet powder were 100% and the most acceptance. This study used amount of soybean powder and milk powder substitutes sugar in the production of powdered rice beverage can be divided into 3 levels in the formula is 5 10 and 15% the result showed that the 10% of the soybean powder and 15% of milk powder substitutes sugar the most acceptance. Then study the temperature of water for rice powder beverages and the ratio of water to the rice powder beverages in the rice powder is 1:5. Nutritional value analysis of rice beverage product showed were 6.46% moisture 11.63% protein 7.34% fat 5.65% dietary fiber 1.47% ash and 67.45% carbohydrate and the shelf-life of rices powdered beverages which pack in aluminum foil bags was preserve products and store at 30 °C more than 6 weeks.
