食用微生物色素的研究进展 总被引:1,自引:0,他引:1
随着人们对食品添加剂的广泛热议,食用色素也备受关注。由于现代生活水平的提高,人们开始追求更加健康的生活方式,故合成食用色素已经不能满足人们的要求。因此,天然来源的食用色素已经成为当今食用色素发展的主流。食用天然色素是指由天然资源中获得的食用色素,主要是指从动物和植物组织及微生物发酵液中提取的色素。但是植物来源的色素会存在来源不易保证、经济花费高和技术方面的问题,而微生物产食用色素则刚好可以解决这些问题。微生物产色素具有生产周期短、产量高的特点,利用微生物产色素则成为当今天然色素的发展趋势。本文将综述微生物色素的分类研究、有食用价值的聚酮类色素及其生产菌株的研究进展,并对其可能产生的毒素进行探讨。 相似文献

Ecological-friendly pigments from fungi 总被引:1,自引:0,他引:1
Durán N Teixeira MF De Conti R Esposito E 《Critical reviews in food science and nutrition》2002,42(1):53-66
The dyestuff industry is suffering from the increases in costs of feedstock and energy for dye synthesis, and they are under increasing pressure to minimize the damage to the environment. The industries are continuously looking for cheaper, more environmentally friendly routes to existing dyes. The aim of this minireview is to discuss the most important advances in the fungal pigment area and its interest in biotechnological applications. Characteristic pigments are produced by a wide variety of fungi and the chemical composition of natural dyes are described. These pigments exhibit several biological activities besides cytotoxicity. The synthetic pigments authorized by the EC and in USA and the natural pigments available in the world market are discussed. The obstacle to the exploitation of new natural pigments sources is the food legislation, requesting costly toxicological research, manufacturing costs, and acceptance by consumers. The dislike for novel ingredients is likely to be the biggest impediment for expansion of the pigment list in the near future. If the necessary toxicological testing and the comparison with accepted pigments are made, the fungal pigments, could be acceptable by the current consumer. The potentiality of pigment production in Brazil is possible due to tremendous Amazonian region biodiversity. 相似文献
