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 Thai wisdom knows the benefits of Carissa carandas L. to be used as a traditional herbal medicine. However there was no scientific evidence to show that Carissa carandas L. of Thailand can treat gout or not. In this research the Carissa carandas L. fruit extract in semi-ripening and ripe stage were studied for the phytochemical and inhibitory activity of xanthine oxidase one of the causes of gout. The result of hytochemical indicated that the crude extract from semi-ripening stage fruit contained many substances; phenolic compounds alkaloids flavonoids terpenoids saponins and deoxy sugars. While the ripe stage fruit contained the similar substances excepted saponins. The extract solution of Carissa carandas L. showed the xanthine oxidase inhibitory activity as the ethanolic extract solution gave the higher activity than water extract solution. The crude extracts of semi-ripening stage fruit presented the higher activity than the ripe stage one with the IC 50 values of 2.40 ± 0.05 and 2.87 ± 0.37 mg/mL respectively. The result of ripening stage with different phytochemical may be related to inhibition of xanthine oxidase activity. Therefore the selecting of sampling period and purification of extract may be a choice for using as medicine for gout

The objective of this research was to study the effects of the processing method on colorant powder from Carissa carandas L. mixed with maltodextrin 3 levels (10 13 and 16 %). The physical properties and consumer acceptance on cotton ball cakes added colorant powder from Carissa carandas L. mixed with all maltodextrin were added at 15% on flour weight. Results from physical properties of cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 10 % was found that the lowest lightness. But also the cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 16 % was exhibited the highest redness and yellowness (p< 0.05) and water activity range from 0.92 to 0.93 (p> 0.05). However the cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 13 % was showed that the highest hardness and chewiness (p< 0.05). Furthermore the colorant powder from Carissa carandas L. mixed with maltodextrin at 10 % was found the lowest adhesiveness (p< 0.05). In addition sensorial evaluation was accepted overall liking score in range 7.63-7.80 (like moderately to like very much. The produce colorant powder from Carissa carandas L. was added maltodextrin from 10 to 16 % (w/w) on (p>0.05).
