Abstract

Red ginger is a biopharmaceutical plant that is used as herbal medicine. The use of red ginger in the food industry is mainly in an emulsion form, but that is unstable and hydrophobic. The ultrasonication technique could change the emulsion into a nanoemulsion to minimize these disadvantages. This research aimed to determine the effect of ultrasonication on red ginger oleoresin nanoemulsion characteristics. The study used a completely randomized design of 4 treatments based on sonication time (0, 30, 60, and 90 minutes). The study was analyzed by ANOVA Tukey's test at P ≤ 0.05, it showed that ultrasonication affected the characteristics of red ginger oleoresin nanoemulsion. The best result shows that in 90 minutes mixed time with transparent yellow colour. It is soluble in acetone, methanol, ethanol, and aquadest solvents. The best particle size is 572.43±8.72 nm, and antioxidant activity is (IC50) 16.34 ±1.33 ppm.©2022 JNSMR UIN Walisongo. All rights reserved.

Abstract

The high level of corn production in Lampung Province has the potential to generate a large amount of corncob agricultural waste. Corncobs are lignocellulosic residues with a high cellulose content, making them a promising raw material for the production of biodegradable bioplastics. This study aimed to produce and characterize corncob cellulose–based bioplastics combined with chitosan as active packaging to extend the shelf life of food products, particularly pempek. Cellulose was extracted through acid hydrolysis, delignification, alkalization, and bleaching processes, and subsequently formulated into bioplastic films using the solution casting method with varying cellulose concentrations. The bioplastics were characterized in terms of thickness, tensile strength, elongation, biodegradability, and water vapor transmission rate (WVTR). The results showed that increasing cellulose content led to an increase in bioplastic thickness and tensile strength, while elongation and biodegradability decreased. Bioplastic thickness increased from 0.18 mm to 0.25 mm, and tensile strength increased from 0.96 MPa to 7.55 MPa with higher cellulose content. Meanwhile, elongation decreased from 98.6% to 45.21%, and biodegradability declined from 38.91% to 23.61%. In addition, the WVTR decreased to 0.021 g/m²·h at the highest cellulose concentration, indicating improved water vapor barrier properties. These findings suggest that corncob cellulose–based bioplastics with chitosan have strong potential to be developed as environmentally friendly active packaging for food products requiring mechanical protection and moisture control.
