Validación de la Tecnología para la Producción e Industrialización de Hongos Comestibles pleurotus ostreatus Utlizando Sustratos Orgánicos.

Abstract

At Animal Microbiology and Biotechnology Laboratory from the ESPOCH Animal Science Faculty, located in Riobamba Canton, Chimborazo Province; the technology for the production and industrialization of Pleurotus ostreatus eatable mushrooms was validated by using organic substrate in base of cereal fuzz (wheat, Triticum spp, oat oat sativa and barley Hordeum bulgare), it was done by using a randomized desing and evaluating different variables during 120 days of research. The bromatological and microbiological characteristics of the substrate used for the mushrooms growing were determined, which differ according to the amout of cereal fuzz that is used, and show the suitable condition for their growing. The highest production of Pleurotus ostreatus eatable mushrooms was also determined when using substrate in base of barley fuzz, obtaining a 20,50% production of mushrooms per substrate. During the industrialization stage some statistical differences among treatments with a higher rate with 99,50 points in industrialized mushrooms into canning jars. The best cost benefit rating was determined when using organic substrate in base of barley fuzz packed into canning jars, obtaining a rate of 1,58. Thus it is recommended to preserve and market them into glass canning jars since a higher productive output and the best acceptance and profitability were determined, showing at the same time, nutritive and organoleptic characteristics which are favorable for human nutrition.
