[Physical, chemical and microbiological quality of concentrated orange juices made in Venezuela].
Concentrated fruit juices are a very attractive type of product because of the many advantages they offer for reductions in packing, transportation and storage costs, and in addition, they offer the possibility of consumption outside harvesting time. Due to their potential in the international market, it is necessary to evaluate if they are accomplishing the quality requirements, and to know the different factors that can affect their stability. For this purpose, samples of national products were analyzed for physical, chemical and microbiological characteristics; the diacetyl test was performed as a measure of the sanitary conditions under processing. The samples analyzed comply with the national standards established by the Comision Venezolana de Normas Industriales (COVENIN N(o) 2395-86 Concentrados de frutas para consumo directo). It is advisable to determine the zero tolerant yeasts population because this type of microorganisms are responsible for spoilage whenever cold storage is interrupted, and because they can not be detected by the official procedures used to detect yeasts.
