Resumen
Las conchas protegen a los moluscos del daño físico, los depredadores y la deshidratación. En este trabajo se estudiaron los diversos usos locales de las conchas y sus propiedades bioquímicas en Abeokuta, Nigeria. Se utilizó un cuestionario estructurado estándar sobre los usos de las conchas, aplicado a 100 vendedores de caracoles y hierbas, conchas de 120 individuos adultos de Archachatina marginata, Achatina Achatina, Achatina fulica, Littorina littorea, Meretrix lusoria y Merceneria mercenaria fueron evaluados para la extracción de los compuestos minerales (Ca2+, Fe2+, Mg2+, Na+, Zn+, P+, K+) y la composición proximal (proteína cruda, materia seca, fibra, contenido graso y carbohidratos) usando métodos estándar. También se analizaron las propiedades de aislamientos contra hongos y bacterias. Las conchas se utilizan para el blanqueamiento, cepillado, abrasión y otros. El peso de las conchas varió de 0.5g (L. littorea) a 25.00g (A. marginata) y el espesor de 0.46mm en M. lusoria a 5.35mm en M. mercenaria. No se encontraron efectos inhibidores de los aislamientos contra hongos y bacterias. Los moluscos resultaron ricos en carbohidratos (83.54-92.76g/100g) y bajos en proteínas (0.16-0.38g/100g). El contenido graso osciló entre 0.42g/100g y 0.82g/100g y la materia seca entre 2.14g/100g y 9.45g/100g. Ca2+ fue el más abundante (10.25-96.35mg/g), mientras que K+ el menos abundante (0.3-0.7mg/g) (p<0.05). Los ingredientes activos de estas conchas se pueden utilizar en la industria alimentaria y de la construcción.Citas
