Effective Utilization of Pineapple Waste

Abstract India is the largest fruit and vegetable producer. Until eaten, peel stays waste. Phenolic acids, ascorbic acid, β-carotenes, flavonoids are most bioactive components of pineapples. This one secondary plant metabolites abundantly present in pineapple skins this sample, ferulic acid. Ferulic acid a low-toxic phenolic widely used diet cosmetics. extracted using different conventional non-conventional methods such as Soxhlet extraction, Supercritical fluid extraction Solvent amount quantified High performance liquid chromatography (HPLC). The study also evaluated presence total content (Gallic equivalent/GAE)and antioxidant activity. methanol petroleum ether was best solvent, showed maximum concentration (0.7696 g/100g), (2.365 mg g/GAE), activity (45%) percentage yield (90.5% mg). analysed micronutrients vitamins (A, B, B1, B2, B6, B12 C), calcium, potassium, phosphorus, iron, manganese, zinc dietary fibre
