For moni toring the analytical Performance, a qoality control exawhnation was also undertaken. The loss of iodine was greater when salt was stored in plastic bag than in glass bottle. The loss was greater in fortified salt stored at 37℃ and under 76% humidity than in that at 20 ~ 25℃ and under lower humidity. The retention of iodine varied with the kind of has and also was influenced by the water content of cooked food. In general, the retention of iodine during cooking varied considerably (from 36. 6% to 86. 1 % ). The iodine concentration in salts varied greater from 3.0 to 100.3 mg/kg in salt for markets, and from 0 to 90.0 mg/kg in salts for households. 48. 3 % of samples from markets were found to be in compliance with national standards (30 ~ 50 mg/kg), and 72.0% of samples from households were in compliance with national standartl (20 ~ 50 mg/kg). Analytical data collected from 8 of the cooperative laheratories foran analytical reference material showed a 95% codridence interval of the population mean for both precision and accuracy, falling within X± 2SD and passing quality control exdrination展开更多

The purpose of this study was to find out the effect of different concentrations of cooking salt and cane sugar on physico-chemical and organoleptic quality of Madurese spicy dried beef. Randomized Block Design with two factors namely concentration of cooking salt （1%, 2% and 3% w/w） and cane sugar （3%, 6% and 9% w/w）, and three replications were used in this study. The increasing amount of either cooking salt and cane sugar incorporated during preparation affected the samples salt, total sugar and moisture contents as well as it＇s aw value and texture of end products. From the organoleptic properties it was found that these treatments only affected the taste of spicy dried beef. Best sample was obtained from incorporating 3% cooking salt and 6% cane sugar with moisture content： 7.11%, aw： 0.354, salt content： 8.17%, total sugar content： 16.91%, texture： 0.0107 kiloNewton and panelists scores tbr texture 5.03; taste 4.53 and colour 5.31. Amino acids profile analysis of best sample showed that the most dominant amino acid was Glutamic acid （7.34%） followed by Aspartic acid （4.15%）, Lysine （3.30%） and Leucine （3.22%）. It can be concluded that to get the best spicy dried beef, the amount of 3% cooking salt and 6% cane sugar should be incorporated during preparation.展开更多
