Abstract

Virgin Coconut Oil (VCO) is derived from fresh coconut meat and can be produced through various methods, including enzymatic processes. This study investigates the effect of adding papain enzyme on the antioxidant activity of VCO. The enzymatic method involves extracting coconut milk with the addition of papain obtained from young papaya. The antioxidant activity was measured using the DPPH method, while other parameters such as moisture content and free fatty acids were also evaluated.The research highlights that VCO is recognized for its health benefits and versatility in various applications. The enzymatic extraction method offers an efficient means of producing VCO while enhancing its properties. This study specifically focuses on how the incorporation of papain influences both the quality of VCO and its antioxidant capacity.In terms of methodology, the study utilized an enzymatic approach for VCO production by incorporating papain into the extraction process. The antioxidant activity was assessed using the DPPH assay, and the resulting VCO was analyzed for moisture content and free fatty acids.The results indicated that VCO produced with papain had a moisture content of 0.22% and free fatty acids of 0.76%, while VCO without enzyme addition showed a moisture content of 0.16%. The antioxidant activity was measured at 18.35 ppm for VCO with papain, compared to 13.51 ppm for pure VCO.In conclusion, the addition of papain enzyme not only accelerated the production of VCO but also enhanced its antioxidant activity, classifying both types of VCO as having strong antioxidant properties. However, it is important to note that the moisture content and free fatty acids in VCO with enzyme addition did not meet the Indonesian National Standard (SNI 7381:2008), likely due to residual water from the papaya fruit.

Abstract

Daun sungkai (Peronema canescens Jack.) merupakan salah satu tanaman herbal Indonesia yang telah dimanfaatkan sebagai obat tradisional diantaranya yaitu sebagai antioksidan. Antioksidan adalah suatu senyawa yang mampu menghambat kerusakan akibat oksidasi radikal bebas. Oksidasi radikal bebas meningkatkan risiko penyakit kronis seperti diabetes, peradangan, hipertensi, penyakit kardiovaskular, dan kanker. Tujuan dari review artikel ini adalah mengetahui potensi daun sungkai sebagai sumber antioksidan alami. Metode yang digunakan dalam review artikel ini yaitu studi literatur terkait manfaat berbagai ekstrak daun sungkai sebagai antioksidan melalui proses pencarian literatur dengan menggunakan artikel penelitian 5 tahun terakhir. Berdasarkan studi literatur yang telah dilakukan menunjukan bahwa ekstrak daun sungkai mengandung flavonoid, fenolik, alkaloid, steroid, triterpenoid. Ekstrak daun sungkai dari berbagai macam pelarut berbeda (etanol, etil asetat, n-heksana, n-butanol, kloroform) mengandung flavonoid. Senyawa turunan flavonoid merupakan antioksidan alami dengan aktivitas penangkal radikal bebas. Kandungan fitokimia yang diketahui masih sangat umum (kelompok senyawa), belum senyawa spesifik (biokatif) yang berperan sebagai antioksidan. Aktiviatas antoksidan pada daun sungkai pada pelarut yang berbeda tergolong kuat. Oleh karena itu, ekstrak daun sungkai berpotensi sebagai antioksidan alam dan perlu dilakukan riset lebih lanjut untuk mengetahui senyawa bioaktif yang berperan penting sebagai antioksidan.

Abstract

Cellulose nanocrystals are a type of cellulose with a nanometer size. Sources of cellulose nanocrystals can come from plants, tunicates, or bacteria. Agricultural wastes have great potential as a source of cellulose nanocrystals. Methods that can be used to isolate cellulose nanocrystals from the main ingredient are hydrolysis methods involving the use of organic acids, enzymatic hydrolysis methods, mechanical treatment methods, or a combination of these methods. Each method has its own advantages and disadvantages. Cellulose nanocrystals have been extensively researched and applied in various fields ranging from reinforcing agents in polymer matrices, playing a role in drug delivery systems, or other polymeric materials. This review provides information on each of the isolation methods and applications of these cellulose nanocrystals. Keywords: Cellulose Nanocrystals, Hydrolysis, Mechanical Treatment.
