Cauliflower powder was developed using the PSBK-1 cultivar, which was dried in a mechanical cabinet air dryer and a solar tunnel dryer. Moisture, protein, carbohydrate, fibre, ash, fat, total polyphenolics, total carotenoids, and antioxidant activity were 7.52 per cent, 16.60 per cent, 46.43 per cent, 14.28 per cent, 4.08 per cent, 1.87 per cent, 122.35 mg GAE/100 g 13.86 mg/100 g, 46.45 per cent, respectively, in cabinet air dried powder, while solar tunnel dried powder had 8.57 per cent, 15.87 per cent, 43.20 per cent, 13.44 per cent The cabinet air dryer and solar dryer took 11.75 and 22.99 hours to dry, respectively. Based on our findings, we discovered that cabinet air drying produced the best results. Further the dried powder analysed for minerals including Na, Ca, K, Zn, Cu, Fe, Mn, and Mg were also found in the dried powder, with levels of 0.43 per cent, 0.28 per cent, 0.38 per cent, 29.10 mg/100 g, 27 mg/100 g 47 mg/100 g, 34.00 mg/100 g, and 0.71 per cent, respectively. Cd, Co, Cr, Ni, and Pb levels per 100 g powder were 0.11 mg, 0.02 mg, 1.23 mg, nil, and 16.61 mg, respectively, according to inductively coupled plasma (ICP) analysis. At 1200, 2000, and 3000 magnifications at 15 working distance, the morphology of the powder was examined using Scanning Electron Microscopy (SEM), which revealed particles with broken glass structure and rough surfaces. Overall, the cabinet dried powder was more visible in shape and size than solar dried powder. Moisture, fibre, ash, total polyphenolics, total carotenoids, and antioxidant activity of cabinet dried powder stored in polyethylene pouches for up to 6 months at refrigerated (4°C) and ambient temperature were 7.52 per cent, 14.28 per cent, 4.08 percent, 122.35 mg GAE/100 g, 13.86 mg/100 g and 57.00 per cent, respectively, with non-significant differences in most of the attributes after 6 months except moisture, total polyphenolics Overall, the powder quality was better when kept refrigerated (4°C) than when kept at room temperature (18-38 °C).
⓿ Mechanical cabinet air dryer and solar tunnel dryer were used for the development of cauliflower powder.
⓿ Scanning electron microscopy (SEM) was used for the morphological quality evaluation of the developed powder by mechanical cabinet air dryer and solar tunnel dryer.
⓿ Functional groups of the powder (developed by mechanical cabinet air dryer) was reviled by Fourier Transmittance Infrared Spectroscopy (FT-IR).
⓿ Atomic Absorption Spectroscopy (AAS) and Inductive Coupled Plasma (ICP) were used for minerals and Heavy metals analysis respectively
