[Preparation and nutritional characteristics of a hydrolysate from pepitona (Arca zebra)].

open access: yesArchivos latinoamericanos de nutricion, 1987
Two soluble products resulting from the hydrolysis of pepitona (Arca zebra) were prepared as flour. Papain at its optimum hydrolysis conditions, previously established, was the enzyme used (40 degrees C for two hours at a pH of 7 in the proportion of 0.3% weight/enzyme/100 g meat).

[Determination of processing conditions for obtaining a pepitona (Arca zebra) hydrolysate for human consumption].

open access: yesArchivos latinoamericanos de nutricion, 1987
For the purpose of obtaining two protein hydrolysates from peptiona (Arca zebra), to be used as nutritional ingredients in accepted food items destined for human consumption, the enzymes bromelain and papain were studied. The effect of adding each of these proteases, on the rate of hydrolysis and conversion extent of insoluble pepitona protein to ...

[Functional properties and possible uses of a hydrolysate of pepitona (Arca zebra) in the preparation of foods].

open access: yesArchivos latinoamericanos de nutricion, 1987
The present study revealed that the drum-drying and spray-drying procedures used on the pepitona (Arca zebra) hydrolysate, as well as the storage time, exert a deteriorative significant effect on the functional properties of both hydrolysates. The greatest and more significant losses of the majority of such properties occur during the first two months ...

[Mollusc diversity in an Arca zebra (Mollusca: Bivalvia) community, Chacopata, Sucre, Venezuela].

open access: yesRevista de biologia tropical, 2002
The diversity of a subtidal epifaunal mollusk community was studied from September, 1990 to September, 1991 in Chacopata, Sucre State, Venezuela. There were 40 species (24 bivalves and 16 gastropods). The diversity indexes (H' = 2.087, J' = 0.392, 1/D = 0.528) were low when compared with other tropical zones.

Esfuerzo reproductivo, índice de engorde y rendimiento en Arca zebra (Filibranchia: Arcidae) por grupos de tallas y su asociación con variables ambientales en el morro de Chacopata, estado Sucre, Venezuela

open access: yesRevista de Biología Tropical, 2016
Arca zebra is a mollusk of commercial value and a major socio-économic fishery in Northeastern Venezuela. The present study aimed to evaluate the reproductive effort (RE), fattening index (FI) and yield (Y) in different size groups of A. zebra from the morro Chacopata, Venezuela. For this, monthly samplings from June 2008 and June 2009, were undertaken,
