Optimization of Nutritional Composition, Bioactive Compounds and Antioxidant Activity in Broccoli (Brassica oleracea) Microgreen Sprinkler using Alternate Drying Techniques

Background: Fresh microgreens are nutrient dense crops with high moisture content, thus have a short life span. Application of different drying techniques enhanced its shelf but leads to losses. There is permanent need enhance the retention in dried microgreen. Methods: The research study investigated during 2019-2020 at Punjab Agricultural University. Broccoli (Brassica oleracea var. Palam Samridhi) seeds were soaked overnight and grown outdoor setting harvested 10th day after germination. broccoli using shade drying, tray microwave drying. Dried samples analyzed for nutritional parameters. Result: Microgreens contain significantly higher nutrients (Ca, Fe, Zn, Mg, K, ascorbic acid b carotene), bioactive compounds (chlorophyll, total flavanoids phenols) antioxidant activity as compared their sprouts mature counterparts. These excellent sources Ca, Vitamin C beta carotene (pro-vitamin A), meeting per cent estimated average requirements (EAR) 536%, 373%, 264%, 228%, 38%, 20% Indian adult. To address problem perishability, there prolong while retaining quality. present has identified optimum technique, on basis retention, from set alternate techniques. Significant content (16.80 mg/100 g), chlorophyll (3.63 g/100 (67.55%), Zn (35.23 Fe (57.66 Ca (2857 K (334.23 g) Mg (706.43 observed microgreens. Incorporation microgreen powder food sprinkler resulted significant increase vitamins, minerals, control.
