| Abstract | ||
| Vegetables are critical to good health, and certainly good for all age categories as it forms an important portion of a healthy diet. Nutritional, chemical composition, physical properties and sensory quality characteristics of vegetables crackers made by mixing wheat flour and fresh, puree and dried for carrot, beetroots and turnip leaves were studied. Wheat flour and puree of turnip leaves, carrot and beet and their powder were mixed in the ratio of 100:00, 90:10 and 80:20 individually. The results showed a significant increase in the antioxidant activity in carrots, beets and fresh turnip leaves, and its decrease after processing (puree and dried). It was noted through this study that the total flavonoids were higher in the puree samples than the fresh ones. Turnip leaf showed a significant increase in phenols and total flavonoids in the case of pureed and dried samples. There were slight significant changes in the betalains and carotenoids pigment in beets and carrot after boiling and drying, respectively and the changes were not noticeable in the state of chlorophyll after boiling and drying in turnip leaves. The content of protein and fiber were significantly increased in samples containing turnip leaves, as well as iron, zinc, phosphorous and calcium in samples containing beets and turnip leaves. These crackers meet a large percentage of the daily needs of these minerals for children from 4 to 8 years old. We conclude from the results of sensory tests that replacing wheat flour with different percentages of dried turnip leaves improved the sensory properties of crackers compared to boiled turnip leaves, while boiled carrots and beet roots were better in sensory evaluation than dry ones. | ||
