| At present, the food industry on the pigment used for the synthesis of pigment, almost has a different degree of toxicity, long-term use would endanger human health, the natural pigment of the scientific research on the growing area of concern. Nutritious carrots, rich in natural active substances, such as carotenoids, anthocyanins, in addition to sugar, calcium, phosphorus, iron, etc., has long been the quality of infant nutrition. In recent years, carrot made of the rapid increase in food, has become a very important special nutritional food, mainly because of the carrot contains a large number ofβ-carotene, which is the precursor of vitamin A substances, their non-toxic, even if a large number of intake would not lead to poisoning. Many researchers proved that,β-carotene in the blood concentration and lung cancer-related [1],β-carotene anticancer effects in the body is not breaking it into two vitamin A molecules, but as a result ofβ-carrot Su-own with biological activity, it can eliminate free radicals in the body, inhibiting the formation of peroxides[2];Secondly, purple carrots contain a large number of anthocyanins, a large number of studies show that: Proanthocyanidins have antioxidant, anti-mutation, Prevention of cardiovascular and cerebrovascular diseases, protect the liver, inhibit tumor cells and many other physiological functions [3,4]. Third, at the same time the experimental determination of the chlorophyll content for the study of metabolism between different active substances in the process of interaction made the initial preparations.The results of this study show that: (1) 2 # variety ofβ-carotene content in the highest, up to 191.01 mg/100g; followed by 4 #, the maximum value of 153.14 mg/100g; Paper Department ofβ-carotene is higher than the center an average of nearly 2-fold. Four varieties of carrot in the threeβ-carotene content of the agreement as follows: upper> middle> lower. (2)The highest total carotenoid was 2 # and 4 #, the highest level of 3.79mg / g and 3.44mg / g; Paper category carotene varieties were significantly higher than the center, up to 2.5 times; four carrot varieties the average levels of carotenoids are: upper>middle>lower. (3) 2 # carrots contained the highest anthocyanins, higher than the other three species of about 19-20 times, which is 2 # was the main reason for the purple; 2 # carpel colors vary greatly, was the center of orange, skin was purple ,the department of its skin anthocyanin content is much higher than the center, the maximum difference of 88 times. 1 #, 3 #, 4 # carpel are basically the same color, little change in anthocyanin content. (4)Chlorophyll a and chlorophyll b in the beginning of the formation of succulent root of a period of time high, with fleshy roots continued growth and deepening the color of its content gradually decreased with the anthocyanin andβ-carotene changes in just the opposite. (5)The most suitable products used in processing raw materials of carrot, the color should be uniform, good quality,β-carotene and anthocyanin content in higher species .This experiment four different varieties of carrot in the natural active substances for a detailed analysis, for carrot breeding, disease prevention and health food products of high nutritional applications provide an important scientific basis, and processed foods carrots selection of raw materials, there are important guidance on a variety of pigment-depth characterization of the research and development to provide the necessary conditions and the theoretical basis, and contribute to its industrial use. |
