MetadataShow full item record
Study about duck cream soup product from waste duck ribs had objectives to study production process of duck cream soup product and to study about chemical and physical quality of duck cream soup product. The procedures in operation are as follows: Study about three basic recipes of duck cream soup product and study about appropriate time period in boiling of duck rib stock for producing of duck cream soup. The duck rib stock obtained from boiling in different three levels of time, as follows: 2, 3 and 4 hours. After that the researcher tested in sensory test in overall appearance, color, smell, flavor, texture and favor. The researcher used method of giving points of 9-point Hedonic scale. There were 40 testing persons. The researcher planned the random test in RCBD: (Randomplete block design) and compare difference of mean by DMRT (Duncan’s New Multiple Range Test). From the study result, it was found that basic recipe cream soup which has been accepted the most of all was Recipe No.2. It was found that the researcher did not give different points to overall appearance, color, smell and favor. The mean was 7.10, 7.23, 7.10 and 7.48 respectively. The Duck rid stock obtained from boiling in different three levels of time, as follows: 2, 3 and 4 hours. Duck cream soup using duck stock for a period of 4 hours, Because of the boiling, simmer for a long time. Cause evaporation of water As a result, the concentration and the smell more pronounced. The mean was 7.18, 7.15, 7.10 and 7.33 respectively, result of chemical and physical quality analysis included viscosity, cream soup duck that the period of boiling for 4 hours of 2 .7 5 x 103 cestipois, the most pH value to be 6.12. This is consistent with generally produce only soup. The viscosity is between 103 to 104, which the retrogradation of the roux. The duck cream soup with and good texture.
