Abstract

Omega-3 fatty acids enriched fish oil from lemuru fishmeal processing met the quality standard of food grade fish oil, but it was susceptible to oxidation. Microencapsulation by spray drying was one method that could protect this oil against oxidation and the microcapsule could be applied more widely and easier to handle. The important factor that affected microencapsulation process by spray drying method was encapsulant to core ratio. The objective of research was to elucidate the effect of encapsulant to core ratio (2:1; 3:1; 4:1; 5:1; and 6:1 (w/w)) on characteristics of ?-3 fatty acids enriched fish oil microcapsule. The increase of microencapsulation efficiency and the decrease of surface oil proportion were related to better emulsion stability prior to spray drying and film forming ability around oil globule as the sodium caseinate proportion increased. Emulsification and heating during spray drying could induce hydrolysis of triglycerides in fish oil. Therefore, the quantity of free fatty acids relatively unchanged although the proportion of encapsulated oil decreased. The decrease of oxidation degree is caused by better protective effect of sodium caseinate during emulsification and spray drying due to better film forming ability as proportion of encapsulant increased. However, it was followed by the decrease of ?-3 fatty acids content that related to decreasing proportion of fish oil. This phenomenon was supported by unchanging ?-3 fatty acids retention that showed protective effect of sodium caseinate on oxidation during microencapsulation. Different encapsulant to core ratio did not change yield of microcapsule. Different proportion of surface oil did not affect microcapsule recovery.Key words : fish oil from by product of lemuru meal processing, ?-3 fatty acids enriched oil, microencapsulation, spray drying, encapsulant to core ratio

Abstract

Antioxidant activity of the javanese ginseng root was investigated. The root extracts were prepared by solvent extraction using methanol, ethanol (96%), ethanol (70%), acetone, and hexane.Total antioxidant activity of the extracts was measured by ferric thiocyanate method, whereas radical scavenging capacity and reducing power were measured by the 1,1-diphenyl-2-picrylhydrazyl and the reducing potential methods, respectively. The result showed that the highest total antioxidant activity was observed in acetone and methanol extracts. It appread that the ability of these extracts for partitioning at the interface of the emulsion in the tested oxidation system was the highest among other extracts, therefore it had the best activity to inhibit oxidation.The highest radical scavenging capacity measured by EC50 was observed in acetone extract. The type of phenolic compounds of this extract appeared to be responsible for the highest radical scavenging capacity. Different phenomena occurred for reducing power.Methanol extract had the highest reducing power and the least were found with the hexane and acetone extract. It was suggested that each extracts comprised different types of phenolic based on different polarity of solvents used for extraction. The antioxidant compounds of javanese ginseng root extracts were primary antioxidant based on the ability to scavenge free radical. It could be concluded that acetone was the best solvent for antioxidant extraction of the javanese ginseng root.However, all tested antioxidant mechanisms in this research showed that vitamin E (1000 ppm) used as control had better activity than javanese ginseng root extracts (1000 ppm) for all types of solvent.Javanese ginseng extracts might contain other compounds which were not responsible for antioxidant activity, therefore at the same concentration the activity were lower than that of vitamin E. Key words: total antioxidant activity, radical scavenging capacity, reducing power, javanese ginseng

Abstract

Emulsification is the critical factor in microencapsulation by spray drying method. Sodium caseinate is a protein with good emulsifying properties. The properties could be improved by phospholipids addition in the emulsification. Phospholipids addition which stabilized oil globule might change the composition of adsorbed layer. This research was conducted to analyze the changes in composition at oil globule interface by analyzing emulsion systems of triglyceride enriched by -3 fatty acids at 5% (w/v) stabilized by sodium caseinate (10% w/v) and addition of phospholipids at 0; 0,5; 1,0; 1,5; 2,0; and 2,5% (w/v). The changes in composition of adsorbed layer could be determined from the changes in phospholipids and adsorbed protein concentrations at oil globule interface. Analyses were done to measure the possibility of casein-phospholipids complex, phospholipids and protein adsorption concentration at interface, and adsorbed protein. The increase of phospholipids concentration in the emulsions stabilized by sodium caseinate changed the composition of adsorbed layer at interface. There was phospholipids increase and adsorbed protein decrease at oil globule interface. These changes were caused by casein-phospholipids complex which that decreased surface activity and displacement protein by phospholipids that was adsorbed at oil globule interface. Changes of composition of casein-phospholipids at oil globule prior to microcapsulation process caused changes in the properties of microcapsule produced. The increasing phospholipids and decreasing casein concentrations at oil globule interface decreased the quality of the microcapsule, including decreasing in microencapsulation efficiency, in oxidative stability, and decreasing in EPA+DHA content.

Abstract

Oil from by-product of lemuru canning processing was a source of w-3 fatty acid but its characteristics had out been known. The content of w-3 fatty acids of this oil had to be increased. Various methods are available to enhance w-3 fatty acids concentration Rapid solidification was one of limited methods to enrich fish oil by w-3 fatty acids containing triglycerides. This research was conducted to optimize rapid solidification condition to enrich fish oil from by product of lemuru canning processing with w-3 fatty acids and characterize the enriched oil compared by International Association of Fish Meal and Oil Manufacturers standard. In optimization process, the content of EPA+OHA and yield .was maximized. A two-factors central composite design in Response Surface Method was used to study the effect of solvent-to-oil ratio (X1) and extraction time (X2). The response (Y) is the multiplication of EPA+DHA content by yield. The results showed that under optimum conditions the maximum response were obtained at a solvent-to-oil ratio of 3,95:1(vw) and extraction time of 24,93 hours. The w-3 fatty acids enriched fish oil had EPA+DHA content of 33,33% and yield of 9.40% (w/w). The produced w-3 fatty acids enriched fish oil had good quality based on food grade fish oil standard, unless Fe and Cu content. Chelation could reduce these oxidizing metals. Key words : w-3 fatty acids, rapid solidification, response surface method, central composite design.

Abstract

Omega-3 fatty acids (w-3) are proven to have health beneficial effects.  Some effort had been done to obtained oil high in w-3 fatty acids.  Among the methods developed, urea crystallization was preferred because it is simple, economic, and result in high purity of fatty acids. A source that had not been widely explored for w-3 fatty acids production is the by-product of tuna meal processing. This research studied the optimization condition for separation and purification of w-3 fatty acids from the by-product of tuna meal processing by urea crystallization. Crystallization reaction conditions of urea inclusion were optimized using the response surface methodology, and the model was developed.Optimization result showed a quadratic polynomial regression equation of Y= 140,52677X1 + 8,38203X2 - 19,85850X12 - 0,12173X22 - 0,74000X1X2 - 240,33546 with X1=urea to fatty acid ratio and X2=crystallization time.  Maximum response was obtained at urea to fatty acid ratio of 3,07:1,crystallization time of 25,10 hours, and predicted response was 80,60%.  Analysis of variance showed that urea to fatty acid ratio and crystallization time affected response.  Under optimal conditions, the product was 3.89 times concentrated and the purity of w-3 fatty acids was 81,98%. Verification result revealed that the predicted value from this model was reasonably close to the experimentally observed value.  Urea crystallization process changed quality parameters that were oxidation level (peroxide value, anisidin value, and totox value), Fe and Cu content, P content, and water content.  The changes were caused by adsorption of primary and secondary oxidation products, part of metals, and phosphoric compound onto unsaponifiable matters or soluble into water.

Abstract

Umbi kimpul adalah salah satu umbi yang banyak ditanam oleh petani di Indonesia. Berdasarkan survey yang dilakukan oleh Deptan, produksi umbi kimpul di Indonesia pada tahun 2013 di 6 provinsi, 6 kabupaten/kota dengan luas 55 ha adalah 825 ton. Produksi umbi kimpul yang melimpah tidak diimbangi dengan pengolahan yang optimal dan cenderung hanya dimanfaatkan sebagai makanan sampingan dengan proses pengolahan yang sederhana seperti pengukusan saja. Kimpul berpotensi untuk dikembangkan sebagai produk olahan mie, namun dalam proses pengolahannya masih memiliki beberapa kendala yaitu tidak adanya gluten yang terkandung dalam kimpul yang berfungsi dalam pembentuk sifat elastis pada mie. Gluten memegang peran penting terhadap karakteristik mie. Pada saat gluten, tepung, dan air bercampur, maka akan terbentuk gluten network yang akan memerangkap air. Semakin banyak gluten yang ditambahkan, maka mie instan menjadi semakin elastis dan kenyal. Untuk itu, diperlukan penambahan gluten agar produk mie memiliki karakteristik yang baik.   Kata Kunci : Gluten, Mie Kimpul, Senyawa Bioaktif, Tepung Kimpul, Umbi Kimpul
