Abstract:
Nutritional research has mentioned that fortification of food by using natural resources is one of the best ways to improve the total nutrient intake of foods with minimal side effects. One of the product categories that can be enriched is fermented products, especially yoghurts. A special category is those for children. In this study the physico-chemical characteristics of four types of yogurts were evaluated. Following the color evaluation, the total colordifference (TCD) increased with the increase in the peach purée concentration, and the values varied between 7.2 and 19. Total acidity values are between 118.75 and 150 ° T, respectively 3.85 and 4.17 pH units. The sodium chloride concentration values were between 0.14 and 0.2 g NaCl/100 g. For fat content the determinate values were lower than those declared (3.2%; 2.7% and 0.8%). Rheological measurements performed showed that all samples behave like a yogurt.
