Abstract
The main aim of this work was to study the physical and chemical properties of Indian fig opuntia fruits. The results indicated that the length, width, and thickness of Indian fig opuntia fruits were 66.68, 46.09, and 43.39 mm, respectively. The geometric mean diameter and arithmetic mean diameter of the Indian fig opuntia fruits were 51.06 and 52.05 mm, respectively. The Indian fig opuntia fruit mass, volume and true density were 68.61 g, 69.39 cm3 and 989.47 kg m-3, respectively. The Indian fig opuntia fruit surface area was 103.68 cm2. The sphericity and moisture content of the Indian fig opuntia fruits were 76.85 and 86.34 %, respectively. The Indian fig opuntia peel, pulp, and seed mass were 29.50, 34.19, and 4.92 g, respectively. The crude protein, ether extract, crude fiber, ash, and total carbohydrates for the raw Indian fig opuntia pulp were 0.81, 0.31, 0.39, 0.43, and 10.95%, respectively. The total solids and total soluble solids of Indian fig opuntia pulp were 13.52 % and 11.21 °Brix, respectively. The titratable acidity was 0.072 % (as citric acid) and pH value was 5.72. Total, reducing and non-reducing sugars of Indian fig opuntia pulp were 10.71, 10.67, and 0.13 %, respectively. The nitrogen, phosphorus, potassium, calcium, and magnesium contents of Indian fig opuntia pulp were 289.5, 136.9, 827.2, 331.2 and 187.1, respectively.
