Abstract

Meatball was Indonesian favorite food made from meat, seasoning and additives. Meatball was perishable due to high water content and nutrition therefore to increase it shelf life there was a need to add natural preservative that have the ability to prevent the growth of microorganism. The aims of the research was to determine the effect of addition on bay leaves extract to the meatball characteristics. The research was conducted using experimental method. The independent variable was bay leave concentration, consist of four stages there were 1%, 2% and 3%. Dependent variables consist of organoleptic characteristics, microorganism using Total Plate Count method, were measure each 2 days during 6 days storage. Result showed addition of bay leave extract can extend meatball shelf life in room temperature for two days. After two days, meatball was deteriorated shown by high number of microorganisms, off-flavor, soft texture

Abstract

New type of cookies has been made by wild yam (gembili) flour to substitute wheat flour.  Starch from gembili (wild yam) contains dietary fiber that can support probiotic growth. The use of gembili starch to substitute wheat flour cookies for toddler is expected to improve the content of dietary fiber in toddler cookies, so that toddlers’ gastrointestinal function is improved. Research on the effect of modified starch in prebiotic toddler gembili cookies was conducted by employing an experimental design of Split Plot Design with two factors: methods of starch modification which were pre gelatinization and autocalving-cooling, and substitution rate of gembili starch (10%,20%,30%,40%). Organoleptic analysis using hedonic quality test showed treatment accepted by panelis was autoclaving-cooling starch with 20% substitution rate containing 6.11% of dietary fiber.

Abstract

The study aims to determine the effect of CMC in preventing yoghurt separation in 7 days with the addition of 2% Dioscorea esculenta flour. Organoleptic test using quality hedonic was conducting to find out yoghurt with addition of CMC that had accepted characteristic by panelists. Research was carried out using regression method to determine the total titrated acid, pH and separation level of yoghurt during storage. The concentrations of CMC were added at 0.2%, 0.4%, 0.6%, 0.8%. The analysis showed the addition of 0.6% CMC showed the lowest separation with high viscosity grades of DPAs 40.25. Yoghurt storage for 7 days shows a graph of the pH value and total titrated acid were parabolic where increasing in total titrated acid value would lower the pH value. Yoghurt was damaged on the 7th day of storage at room temperature characterized by the increasing in the pH value and damage to the organoleptics properties, namely yoghurt flavor and aroma.
