Langostilla (Pleuroncodes planipes), Stimpson: mineral content under different preservation procedures

After freezing, pressing, boiling, boiling-pressing, sun-drying and oven-drying procedures, minerals such as zinc, copper, sodium, potassium, calcium, iron and manganese were quantified in red crab (Pleuroncodes planipes) meal. The results indicated that each treatment affected the content of the majority of the minerals studied, excepting phosphorus, copper, zinc and iron. Calcium and potassium were showing a major statistical significant variation. The oven-drying method preserved the quantities of most of the minerals, and it can be used in a wide range without affecting the mineral content, specially for use of this marine resource in animal feeding, and for ration formulation with a slight margin of error.
