Abstract

Palm oil is the world's main vegetable oil commodity and significantly contributes to the food industry. However, challenges related to the low content of certain nutrients and susceptibility to lipid oxidation are major issues that affect product quality. Fortification technology is an innovative solution to improve palm oil's nutritional value and oxidative stability. This article aims to evaluate the development of modern technology in palm oil fortification, including the addition of vitamin A, vitamin E, bioactive compounds, and the use of natural and synthetic antioxidants. Various methods, such as microencapsulation, nanotechnology, and biofortification techniques, are discussed in the context of their effectiveness in maintaining nutritional stability, preventing lipid oxidation, and extending product shelf life. This review highlights the challenges of implementing fortification technology, including technical and regulatory aspects in the food industry. The results of the review indicate that fortification technology improves nutritional quality and the oxidative stability of palm oil, thus supporting the development of healthier and more value-added food products. The implementation of vitamin A and E fortification with nanotechnology is expected to be able to answer global nutritional challenges and increase the competitiveness of the palm oil industry in the international market.

Abstract

The valorization of agro-food waste represents a promising pathway toward sustainable bio-based materials. This study aimed to formulate a fermentation medium from rice panicle straw (merang) and watermelon rind for producing eco-friendly SCOBY (Symbiotic Culture of Bacteria and Yeast) biofilm. The waste materials were thermally extracted without filtration to retain active solids and subsequently fermented with lactic acid bacteria for 14 days. The fermentation broth was enriched with soybean flour as a nitrogen source and Ziziphus mauritiana leaf extract as an antioxidant additive. Phytochemical screening was conducted using colorimetric reactions analyzed through chromaticity coordinates for flavonoids and grayscale intensity for alkaloids. SCOBY growth was evaluated by measuring biofilm thickness, wet and dry weight, tensile strength, and elongation at break. The results revealed that the combination of these residues provided sufficient nutrients and bioactive compounds to support SCOBY development. The best treatment produced a biofilm with 4.51 mm thickness, 17.49 g wet weight, 3.86 g dry weight, 43.11 MPa tensile strength, and 6.66% elongation. Colorimetric evaluation showed a red chromaticity spectrum for flavonoid presence (dominant wavelength 620 – 625 nm, purity 81.04%), and a clear white grayscale range (220 – 240) for alkaloids. In conclusion, this formulation offers a simple, low-cost approach to converting agricultural waste into functional biofilms. Further investigations are recommended to evaluate the shelf life and potential of liquid SCOBY as a plant immunomodulator and biofilm as organic packaging.
