Abstract

Gelatin is a denaturation product of collagen and has been widely utilized for foods, photography uses, medical materials, and culture materials for microorganisms. Recently, gelatin’s uses has expanded to new applications such as health foods. Gelatin of land animal origin such as bovine and porcine has been mainly used. However, gelatin with new properties is desired to develop expanded applications. In this research gelatin was made from shark skin. The shark skin collagen was distended by acetic acid solution (acid process) and sodium hydroxide solution (alkali process), and gelatin was then extracted at 80oC of water. The extracted gelatin was dried by vacuum drying and freeze drying to obtain powder product. Shark gelatin produced by the combination of alkali and vacuum drying process (OVB gelatin) had better qualities on yield, water content, gel strength, melting point, and emulsion stability as compared to the others. Sensory evaluation indicated that shark gelatin had lower values in color, odor, and performance as compared to the commercial gelatin of fish, pig and bovine (SKW Biosystem). However, as compared to the commercial gelatins, OVB gelatin had a similar values on gel strength (202 bloom) and emulsion stability (100%), but higher values on viscosity (8 cP) and pH (9.3). Those values indicated that ray skin gelatin can be used to substitute the commercial gelatin in some food industries Key words: Gelatin, shark, melting point, and emulsion stability

Abstract

The research of nano-carotenoid making from palm oil carotenoids by sonication method have been conducted. This study was devided into the following stages: (1) the manufacture of nano carotenoid concentrations by sonication process at 80% intensity for 1-5 hours, (2) nano emulsion formulation of carotenoids, (3) the preparation of nano-carotene formula for drying process, (4) product analysis. The smallest particle size of carotenoid concentrations obtained by 2 hours sonication process with 44579.31 ppm carotenoid content. The best composition for nano-carotenoid emulsion is concentrat: water: Tween-80 for 2:2:1. Powder form obtained by using spray drying method. The results of the analysis shows moisture of the products is 4.25%, while carotenoid content of the product is 9,496.663 ppm.Keywords : emulsifier, encapsulation, carotenoid, crude palm oil, sonication.AbstrakPenelitian pembuatan nano karotenoid asal minyak sawit dengan cara sonikasi telah dilakukan. Tujuan penelitian ini adalah untuk mempelajari pembuatan nano-karotenoid dengan teknologi sonikasi serta mempelajari proses pembuatan serbuk nano-karotenoid sebagai alternatif sediaan suplementasi provitamin A. Penelitian ini meliputi 4 tahap kegiatan yaitu: (1) pembuatan nano konsentrat karotenoid dengan cara sonikasi pada intensitas 80% selama 1-5 jam; (2) formulasi emulsi nano karotenoid; (3) pembuatan formula untuk nanokaroten kering; (4) analisis produk. Hasil penelitian diperoleh bahwa ukuran partikel produk nano konsentrat karotenoid yang terbaik diperoleh dengan proses sonikasi dalam waktu 2 jam yaitu kurang dari 100 nm dengan kandungan karotenoid sebesar 44.579,31 ppm. Adapun formula emulsi nano karotenoid yang stabil menggunakan emulsifier Tween 80 dengan perbandingan konsenstrat:air:emulsifier adalah 2:2:1. Produk serbuk nanokaroten terbaik dibuat dengan menggunakan penyalut maltodekstrin (1:1) dengan cara pengering semprot. Hasil analisis produk yaitu kadar air 4,25% serta kandungan karotenoid dalam formula emulsi produk enkapsulasi adalah 9.496,663 ppm.Kata Kunci : emulsifier, enkapsulasi, karotenoid, minyak sawit, sonikasi.
