Abstract

Red palm oil (RPO) is an intermediate superfood derived from palm oil, with the potential to reduce stunting and supply sustainable phytonutrients aligned with SDGs 4 in Ibu Kota Nusantara (IKN), East Kalimantan. RPO contains significantly higher carotene levels than commercial oils which is produced through physical modification processes to remove phospholipids and palm distinctive smell by beta-ionone. This study focuses on optimizing the deodorization process that removing impurity and volatile compounds. The optimization used Response Surface Methodology (RSM) with Central Composite Design (CCD) across 13 experimental runs, varying two key parameter temperature (118–133°C) and heating time (238–253 minutes). The novelty of deodorization process using multi-flash autovaporization by lower temperature for better preserve carotene. The effects on carotene content, free fatty acids (FFA), and density were analyzed using Design Expert 13 software. The optimal condition was found at 120°C for 240 minutes, resulting in 280 ppm carotene, 1.11% FFA, and a density of 0.948 g/cm³. The carotene kinetic model has been foundwhere X is temperature and Y is time. Statistical and graphical analysis confirmed that the final product met Indonesian standards SNI 3741:2013 and 9098:2022, which require FFA below 5% and carotene above 30 ppm.

Abstract

The use of conventional plastics, which are difficult to degrade, has caused serious environmental problems, necessitating alternatives in the form of biodegradable plastics (bioplastics). Biofilms are anticipated to address social issues in line with the 12th SDG goal, namely the management and reduction of packaging waste generated daily. By utilizing abundant local cassava starch, the produced biofilms are anticipated to possess good mechanical properties and low water absorption, making them a potential eco-friendly alternative for food packaging while supporting the use of local resources. This study aims to develop cassava starch-based biofilms as environmentally friendly packaging by optimizing the formulation of carboxymethyl cellulose (CMC) and glycerol. The research employs cassava starch as the primary matrix, CMC as a filler to enhance mechanical properties, and glycerol as a plasticizer to improve the flexibility of the biofilm. The research methods include cassava starch extraction, mixing of materials with stirring and heating, and drying the gel into a biofilm. The biofilm's characteristics were analyzed through tensile strength and elongation tests. The results showed that the formula with a cassava starch concentration of 15 grams, 1% CMC, and 6% glycerol yielded the highest tensile strength value of 1.56 MPa, meeting the Japanese Industrial Standard (JIS) for edible films (≥ 0.392 MPa). The best elongation value reached 199.6%, demonstrating excellent flexibility according to JIS and Indonesian National Standards (SNI). This study indicates that the appropriate combination and concentration of materials can produce biofilms with the potential to replace conventional plastics, support environmental sustainability, and optimally utilize local resources
