菠蘿果實(shí)維生素組分和含量變化的研究
[Abstract]:With the improvement of living standards and the increasing number of sub-health conditions, the health care function of food has been paid more and more attention. Pineapple has unique flavor and rich nutrition. It is favored by consumers at home and abroad. It is one of the three tropical fruits in the world to study the changes of vitamin composition and content of pineapple fruit, which can be used for the selection of pineapple varieties. Cultivation and production and processing to provide scientific basis. In this study, HPLC method was used to analyze the four ripening stages (green, yellow, complete and overripe) of Bali, Caine, Golden pineapple and Mibao (Tainong 19) fruit. The contents of vitamin A, vitamin C, vitamin B3, vitamin B12 and vitamin B6 in winter fruit and summer fruit of Bali and Caine were different in 11 varieties of ripe fruit (yellow mature period), such as Shenwan, Perfume (Tannong 11), Golden pineapple and so on, and the contents of vitamin A, vitamin C, vitamin B3, vitamin B12 and vitamin B6 in different areas. The results are as follows: 1. The contents of vitamin A, vitamin C and vitamin B _ 3 decreased with the fruit ripening, while the contents of vitamin B _ (12) and vitamin B _ (6) increased from green to overripe. Among them, the content of vitamin A in Bali was the largest in 0.0020mg/g-0.0038mg/g, the change in vitamin B3 in pineapple was the biggest in 0.0046mg/g~0.0110mg/g, and the content of vitamin A in Balinese was the largest in 0.0046mg/g~0.0110mg/g. The changes of vitamin C and vitamin B6 were the largest, between 0.0885mg/g-0.2608mg/g and 0.0125mg/g-0.0698mg/g, respectively. The content of vitamin A was the highest in the mature stage and the highest in the mature stage of the four varieties, and the content of vitamin B 12 was the highest in the mature stage of the four varieties. The contents of vitamin C and vitamin B _ 3 were the highest in the mature period of golden pineapple and the highest in the over-maturation period of Mepao. Vitamin B 12 was not detected in Bali and vitamin B 6 was not detected in Bali. 2. Among 11 varieties of pineapple, vitamin C content was between 0.10mg/g~0.23mg/g, vitamin A content was between 0.0016mg/g~0.0038mg/g and vitamin B3 content was between 0.0038mg/g~0.024mg/g. The content of vitamin B _ 6 is quite different, and the content of vitamin B _ 6 is different between 0.0045mg/g~0.067mg/g. Balinese, perfume, Golden Winter Sweet,New Phuket,Phuket5 varieties did not detect vitamin B 12, other varieties of vitamin B 12 content in the range of 0.0020mg/g~0.012mg/g. There were significant differences in vitamin A, vitamin C and vitamin B6 between the cultivars except vitamin B _ 3 and vitamin B _ 12. The content of vitamin A in Bali was significantly higher than that in other varieties, the content of vitamin C in perfume was significantly higher than that in other varieties of, Golden Winter Sweet, the content of vitamin B3 and vitamin B6 in other varieties was the highest, and the content of Mepao vitamin B12 was the highest. 3. There were significant differences in five vitamins in Balinese three areas, but no significant difference in vitamin A and vitamin C between Zhanjiang and Hainan, but they were all significantly higher than those in Yunnan, and significant differences were found in other vitamin 3 areas. In winter fruit, the vitamin C content in Hainan was significantly higher than that in other regions, and vitamin B6 in Yunnan and Hainan was significantly higher than that in Zhanjiang. In summer, the content of vitamin C in Zhanjiang area was significantly higher than that in other areas, and the content of vitamin B3 in Yunnan area was significantly higher than that in other regions. 2 the contents of vitamin C, vitamin B3 and vitamin B6 in winter fruit of Zhanjiang region were lower than those in summer fruit. The contents of vitamin A and vitamin B12 were opposite. 2. Vitamin E was found in winter fruit, but no vitamin E was detected between 0.10~0.25mg/g and summer fruit. No vitamin B12 was detected in Bali, Zhanjiang, and vitamin B6 was not detected in Bali, Hainan.
