Abstract

Samples of a carbonated orange drink, raw materials, and intermediate products originating from 6 Iraqi bottling plants were examined. 69 drinks, 4 flavoured syrups and 19 simple syrups contained yeasts, whereas all samples from one plant and all samples of beverage base were free from viable yeasts. From the orange drink 2 species were isolated viz. Saccharomyces montanus and Torulopsis stellata. The following species were present in simple syrup: Hansenula anomala, Sacch. bisporus var. mellis, T. candida and T. stellata. Sacch. bisporus var. mellis was also isolated from favoured syrup. Representative strains were submitted to routine growth tests at reduced oxygen tension, at reduced water activity and on solid soft-drink media containing various amounts of anti-microbially active benzoic acid at pH 3.0. The results are discussed and compared to those obtained in European soft drinks.

摘要

对来自伊拉克6家瓶装厂的碳酸橙汁饮料、原材料及中间产品样本进行了检测。69种饮料、4种调味糖浆和19种单糖浆中含有酵母菌，而来自一家工厂的所有样本以及饮料基料的所有样本均无活酵母菌。从橙汁饮料中分离出2个菌种，即蒙塔那酿酒酵母和星状球拟酵母。单糖浆中存在以下菌种：异常汉逊酵母、双孢酵母蜂蜜变种、假丝酵母和星状球拟酵母。双孢酵母蜂蜜变种也从调味糖浆中分离得到。选取代表性菌株在低氧张力、低水分活度条件下以及在pH值为3.0、含有不同量具有抗菌活性苯甲酸的固体软饮料培养基上进行常规生长试验。对结果进行了讨论，并与欧洲软饮料的结果进行了比较。
