Abstract
Gamma oryzanol (GO) is the rice bioactive compound which presents various therapeutic effects. However, GO is relatively unstable to environmental factors during processing and storage. The objective of this work was to produce GO microparticles encapsulated with inulin and Tween80 (GOINs) by spray-drying. Response surface analysis was used for the optimization of the encapsulation to get maximum % encapsulation efficiency (%EE) of GO. Three process variables for the concentration of 10–20% inulin (w/v), 3–5% Tween 80 (w/v), and 3–5% GO (w/v) were investigated. Quadratic polynomial regression model for the optimization with R2 at 0.92 was obtained from the study The optimum condition was 20% inulin (w/v), 3% Tween 80 (w/v), and 3% GO (w/v) which yielded a high % EE of 82.63% and particles size at 1,154.60 ± 28.85 nm Fourier transform infrared spectroscopy demonstrated that GO was encapsulated inside the inulin matrix. Our study provided potential and improved hygroscopicity ranged from 6.51 to 10.22 g H2O/100 g dry weight of GO in spray-dried microcapsules.
期刊介绍:
The Journal of Food Science and Technology (JFST) is the official publication of the Association of Food Scientists and Technologists of India (AFSTI). This monthly publishes peer-reviewed research papers and reviews in all branches of science, technology, packaging and engineering of foods and food products. Special emphasis is given to fundamental and applied research findings that have potential for enhancing product quality, extend shelf life of fresh and processed food products and improve process efficiency. Critical reviews on new perspectives in food handling and processing, innovative and emerging technologies and trends and future research in food products and food industry byproducts are also welcome. The journal also publishes book reviews relevant to all aspects of food science, technology and engineering.
