Implementación y evcaluación de buenas prácticas de manufactura (BPM) y procedimientos operativos estándar de saneamiento (POES) en la Empresa de Lácteos San Salvador

Abstract

At the dairy products plant San Salvador located in Riobamba, Riobamba Canton, Chimborazo Province, a plan of good manufacturing practices (BPM) and standard sanitation operative procedures (POES) were implemented and evaluated. Organoleptic, physical and chemical and microbiological analyses for raw milk, fresh cheese, mozzarella cheese and yogurt were conducted taking samples from the reception of the raw material up to the final product for the products of the areas of cheeses and ferment milk. These analyses were carried out before and after implementing the BPM and POES plan. An auditory was performed every month for each enterprise area to guarantee the plan accomplishment and efficiency. Efficiency improved periodically in all the areas which were significantly related to the implementation of the BPM and POES (P<0.01). The general enterprise efficiency reached a valuation of 99.42% and for each day of the plan application efficiency improved by 0.18%. The microbial charge was also considered through the microbial analyses of total aerobes and total colliforms, being 85°C the highest efficacy in pasteurized milk, 99.94% in the AT control and 100% in CT. All products reduced their microbial charge by almost 100%. The implementation of the BPM and POES plan in the Dairy products Plant San Salvador influenced on the final product quality. It is recommended to continue training permanently the plan personnel with new quality assurance programs.
