摘要:

以亚硒酸钠为硒源,通过蝉花孢梗束的富硒培养,探究硒对蝉花孢梗束营养和功能成分的影响,并对富硒蝉花孢梗束蛋白质的营养价值进行评价。结果表明,蝉花孢梗束中硒的含量随培养基中外源添加量的增加而提高,当培养基中亚硒酸钠浓度为100 mg·kg-1时培养的蝉花孢梗束中硒含量达到142.22 mg·kg-1。富硒培养的蝉花孢梗束中蛋白质、脂肪、腺苷和甘露醇的含量均较对照组有显著的提高,在培养基中亚硒酸钠浓度为75 mg·kg-1时富硒蝉花孢梗束的蛋白质氨基酸比值系数分(SRCAA)为52.60,高于对照组。聚类分析表明,总体上富硒培养时亚硒酸钠浓度越高对蝉花孢梗束营养和功能成分影响越大。综合分析得出,当培养基中亚硒酸钠浓度为75 mg·kg-1时既能提高蝉花孢梗束中蛋白质、脂肪、腺苷和甘露醇的含量,又能提高蝉花孢梗束的蛋白质营养价值。

Abstract:

The effect of selenium on the the nutrition and functional components in the synnemata of Isaria cicadae was explored by the selenium-enriched culture of synnemata of I. cicadae using sodium selenite as the source of selenium. And the nutritional value of the protein of synnemata of I. cicadae was evaluated. The results showed that the selenium amount of synnemata increased with the increase of sodium selenite in the culture media. When the concentration of sodium selenite was 100 mg·kg -1 in the medium, the selenium content in synnemata of I. cicadae reached 142.22 mg·kg -1. The contents of protein, fat, adenosine and mannitol in the selenium-enriched synnemata of I. cicadae were significantly higher than those of the control group. The amino acid ratio coefficient score (SRCAA) of protein of synnemata of I. cicadae, cultured in the media with 75 mg·kg -1 sodium selenite, was 52.60, which is higher than the control group. Cluster analysis indicated that, in general, the effect of sodium selenite on the nutritional and functional components of synnemata of I. cicadae were increased with the increase of sodium selenite in the culture media. It can be concluded that when sodium selenite was 75 mg·kg -1 in the media, it could not only increase the contents of protein, fat, adenosine and mannitol in synnemata of I. cicadae, but also increase its protein nutritional value.

Key words: Isaria cicadae, synnemata, selenium, nutritional value, functional components
