| Abstract | The objective of this research was to study optimal ratio of yogurt ice cream mix, blended Khaomak and water in Khaomak yogurt ice cream.Mixture Design was used for formulating mixture of yogurt ice cream mix (6080%), blended Khaomak (515%) and water (020%).The viscosity and %overrun of Khaomak yogurt ice cream,80% yogurt ice cream mix, 5% blended Khaomak and 15% water (trt1)gave the highest values which were174 cPand 11.35%, respectively. Khaomak yogurt ice cream at ratio of 65:15:20 (trt3)gave the highest melting rate. Total soluble solid fromKhaomak yogurt ice cream at ratio of 80:15:5 (trt2) and trt1gave the highest valueswhich were 26.97?Brix and 25.83?Brix, respectively.Treatmentwith high amount of blended Khaomakcaused decreasingin L* and increasingin a* and b*(p?0.05).The acidity of Khaomak yogurt ice cream was mainly from yogurt ice cream mix, trt2 gave the highest acidity which was 0.45% total acid and pH 4.85.Total bacteriaof all treatments were in range of 7.507.90log cfu g-1and lactic acid bacteria were in rangeof7.407.80log cfu g-1, yeast and mold were less than 10cfu g-1.Microbiological analysis of all treatmentsmet the requirement offermented milk product standard issued by the Ministry of Public Health, Thailand.The ratio of yogurt ice cream mix, blended Khaomak and water at ratio of 80:5:15 (trt1) obtained the highest liking scorein all attributesincluding overall liking(7.08) with just right higher than 50% in Just about right(JAR)test for all attributes. |
