Optimization of freeze drying parameters for moringa (Moringa oleifera) flower powder by using response surface methodology and principal component analysis
نویسندگان
چکیده
Moringa oleifera Lam. is an incredible plant because of vital nutrients such as minerals, vitamins and phytochemicals. The present work focused on studying the optimization quality attributes retention in moringa flowers a freeze dryer (FD). Because conventional drying process takes more time energy which will affect product safety. Response surface methodology (RSM) was employed to optimize effect temperature (- 65 - 45°C), vacuum pressure (0.5 2.5 mmHg) (18 24 h.) vitamin C, total antioxidant activity(TAA) hygroscopicity (HS) flower. developed model response R2 values C 0.96, activity 0.97 hygroscopicity0.95. Based desirability (0.74) functions, flower sdried at 63.75°C for18 hr under 0.55 had optimum level 285.84 mg/100g, TAA 453.20 mg/100g HS 1.57 percent. Freeze dried powder -55°C maximum characteristics with special reference high recovery (98.75%) excellent flowability.The first principal component, accounting for 52.15 per cent two 23.02 variance resolved different temperatures.
