การบำบัดน้ำเสียจากสีย้อมผ้าด้วยกระบวนการโอโซนเนชัน โดยใช้ตัวกลางพลาสติก เคลือบผิวไทเทเนียมไดออกไซด์ชนิดรูไทล์เป็นตัวเร่งปฏิกิริยา
This research is to study the efficiency of treating wastewater from dyeing fabric by the ozonation process. By using rutile TiO2 coated plastic media to catalyze. Which uses O3 generators with a capacity of 2.62 - 3.10 g/hr. By studying the factors that affect the treatment efficiency of COD and color such as the pH of the water used in the treatment at pH 3 pH 7 and pH 11 the initial COD concentration of 100% 50% and 25% which have values in the range of 100 -320 mg/L. O3 exposure time 120 min. From the study it is found that the efficiency of reducing the impurities in wastewater by the ozonation process in the pH 11 state the COD concentration at 50% can reduce the COD. And the maximum color is at 33.3% and 90% from the 550 ADMI color intensity with a COD of 180 mg/L. For the study of the efficiency of reducing the impurities of wastewater by ozonation process together with 2 g. of TiO2/1 L. of wastewater in the condition of pH 11 concentration COD Beginning at 100% with the ability to reduce COD values And the maximum color is at 40% and 80% of the 270 ADMI color intensity with a COD of 190 mg/L. The amount of O3 suitable for treatment has an average value of 0.0374 g/min./10.5 L. of wastewater. The duration of O3 exposure in both processes has a similar approach to the efficiency of COD and color treatment when increasing the duration of O3 exposure.

The objectives of the research on the application of dry ice in making chocolate mousse for the cold western dessert competition were to study the appropriate time for freezing chocolate mousse and test the physical quality of frozen chocolate mousse using randomized complete block design (RCBD) method at 95% reliability. The quality of senses sight color smell taste and texture and the overall preference were evaluated. The difference of mean was compared with by Duncan New Multiple Rang Test (DMRT) using a computer program to find the appropriate time to freeze chocolate mousse. 15 testers applied the 5 – point hedonic scale to test the product. Research results showed that the testers preferred the product that was frozen for 40 minutes the most. In terms of color smell taste and overall preference the mean was 4.50 4.41 4.00 4.35 4.25 and 4.21 respectively. The physical quality test results indicated that the texture of the mousse frozen for 30 minutes had the best hardness adhesion and flexibility 27.53 3.17 0.43 and 1.21 respectively. The product frozen at 40 minutes had the highest lightness (L*) yellowness (b*) and redness (a*) 40.15 13.03 and 22.31 respectively with the statistical significance (p≤0.05).

Study on the amount of soybean powder for substitution of coconut milk powder. The purpose is to reduce fat from coconut milk and use soybean powder to replace the concentration of finished coconut milk. By studying the basic formula of coconut milk powder by selecting 3 formulas and taking the most scores formula Bake at 70 degrees Celsius for 7 hours humidity at 1%. The results of consumer acceptance study by measuring the quality of the appearance texture color smell By leading to being accepted by consumers Testing the quantity of soybean powder suitable for the product by measuring the quality of appearance texture color smell. To be acceptedby consumers Study on shelf life of soybean powder substitution products in coconut milk powder in replacement of soybean powder Suitable and accepted by consumers Taken separately in an aluminum foil bag During the 2 month storage period quality assessments are done every 2 weeks. By measuring moisture color Aw and general microbes and mold yeast. Found that longer duration increased moisture and microbial values. But the number of microbes is less than 1 × 103 colonies pergram which does not exceed the standard of the community product standards.

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 objective of this research was to develop ready- to- drink yogurt products from mixed fruits and vegetables. By starting with studying the stability level of basic yogurt formula In gelatin is added in 3 levels of basic yogurt products to be used as ingredients in fixed basic yogurts 2 4 and 6 percent with other components in the formula: Pasteurized milk natural flavored yogurt granulated sugar and gelatine Studies have shown that using basic formula yogurt with 4 percent stability is the right amount for making basic stable yogurt. Which the yogurt has 21 solids soluble in water white light yellow The texture of the yogurt is stable. After that mix yoghurt and fruit and vegetable juice to produce curdled milk. By studying the ratio of basic formula yogurt and fruit and vegetable juices in 3 different ratios namely 30:70 50:50 and 70: 30 percent. The quality test results showed that 50: 50 percent formulas had the pH 4. 37 the amount of solids that Soluble in 15 ◦Brix water and are the most accepted formulas. Analyzing the chemical composition thisreducedsugar drinking yoghurt from fruits and vegetables had moisture ash fat protein fiber protein and carbohydrate was found to be 86.81 ± 2.83 0.40 ± 0.32 0.37 ± 0.23 3.02 ± 0.77 0.14 ± 0. 26 and 9. 25 ± 0. 41. Stored at 4 ± 1 ° C for 15 days found that total microbial count yeast mold And coliforms do not exceed the standards set (Notification of the Ministry of Public Health 353/2013)
