Abstract:
Fresh Asiatic clams (Corbicula manilensis) from Region 2, Philippines, were
processed using vacuum frying to develop a nutrient-dense and shelf-stable
product. Process optimization at 100 °C, 700 mmHg, and a 6 kg batch load yielded
the most favorable sensory attributes and the highest product recovery. The
optimized treatment (T6) contained 28.66 g protein, 35.25 g carbohydrates, 25.72 g
fat, 7.49 g ash, and 2.88 g moisture per 100 g sample. Shelf-life evaluation showed
stability for up to four months under ambient conditions, with quality deterioration
observed beginning at the fifth month. The product exhibited a low microbial load
(<1×10¹ CFU/g) and notable mineral content, particularly zinc and iron. These
results demonstrate that vacuum frying effectively produces a nutrient-rich, safe,
and shelf- stable clam-based product, with potential for extended shelf life through
improved packaging.
