Abstract

Sebagai negara maritim, Indonesia memiliki keragaman hayati yang berlimpah di antaranya berbagai jenis rumput laut atau makroalga, yang lazim disingkat dengan alga. Salah satu substansi kimia dari rumput laut  yang  bermanfaat  adalah karbohidrat  berupa  polisakarida seperti alginat, karagenan, dan agar, sedangkan komponen penting lainnya adalah protein, lemak, dan vitamin yang semuanya merupakan metabolit primer.  Metabolit primer tersebut telah banyak dimanfaatkan untuk bahan baku industri, makanan tambahan, sayuran, dan bahan obat-obatan guna  memenuhi  kebutuhan di dalam negeri dan untuk diekspor. Di samping itu, alga juga merupakan sumber senyawa bioaktif, yang merupakan metabolit sekunder yang memiliki aktivitas  seperti  antibakteri, antitumor, antiinflamasi, dan lain-lain. Pemanfaatan metabolit  primer dari alga telah cukup berkembang namun pemanfaatan metabolit sekundernya hingga saat ini masih terbatas.

Abstract

Fish handling is one of factors that affect fish quality deterioration, including slaughtering technique. In this study, the quality deterioration of fresh patin Siam catfish (Pangasius hypopthalmus) which were handled with different slaughtering techniques was observed. Fish were fasted for one day before slaughtered with two different techniques namely live-chilling and bleeding techniques. Live-chilling technique was conducted by exposing  fish into cold water with temperature of 0-5°C for 15 minutes, while bleeding technique was conducted by cutting directly on the arteries part of fish head. After being slaughtered, fish were then stored at ambient temperatures for 18 hours and observed for its quality deterioration in every 3 hours. The observed parameters of fish quality deterioration were including the sensory attributes which were described using descriptive test by trained panelists; chemical parameters including proximate analysis; pH and Total Volatile Base (TVB), and microbiological parameters including Total Plate Count (TPC), coliform and E.coli. Results showed that the flesh of patin Siam catfish slaughtered by live-chilling technique had more blood in the fish body tissue, while bleeding technique resulted in much brighter flesh as well as abdominal cavity. The flesh quality decreased after 18 hours of storage in both treatments, but no significant changes in their proximate values. Bleeding technique was more recommended compared to live-chilling technique for slaughtering patin Siam catfish due to its predominance in producing better flesh quality.

Abstract

The brown seaweed Sargassumsp. is well known as a source of fucoidan. Brown seaweeds found in Indonesia seas are dominated by Sargassum sp.The objectives of this research was to purify and characterize fucoidan from S. binderi Sonder. The fresh raw material was defatted by macerated in methanol:chloroform:water (4:2:1), filtered, rinsed with acetone and then air-dried in room temperature. The defatted dried seaweed was extracted with 0.01M HCl pH 4 at room temperature. Purification has been conducted using anion exchanger. The quality of fucoidan sample was determined for total sugar, functional group using FTIR, monomer content, total ash, and total sulfate in the ester form. The result shows that pure fucoidan contains fucose as the primary sugar component, and otherminor sugars (galactose, glucose, mannose and xylose). Chemical composition of crude fucoidan consisted of 74.25% fucose; 0.28% uronate acid; 10.29% sulfate and 5.5% protein. Purification using DEAE Sephadex A-25 gave 4 fraction pools yielding total sugar (%) of F1 (17.59); F2 (18.92); F3 (13.72); F4 (49.76), respectively. The components that build the fucoidan of S. binderi Sonder were estimated derived to be from fucoidan oligomers including (1,4)-L-FucS-Gal and D-(1,4)-Gal-GalS.

Abstract

Screening of significant variables of Sliced Frying Fish Ball (Basreng) has been conducted using Plackett-Burman Design, a statistical method commonly used to reveal the significance of variables in the product development. Four variables were selected namely tapioca flour, potato flour, fish, and frying time. Twelve formulations were peformed and the final products were analyzed for their sensory and texture parameters. Six responses were chosen (appearance, color, odor, taste, texture, overall acceptance and hardness) and then evaluated based on their significance, coefficient value and ranking test through appropriate statistical analysis. The result showed that four variables gave positive and negative effects to the products. Based on overall ranking test, tapioca flour was placed at the first place meaning that it had highest desirable properties followed by frying time, potato flour, and fish flesh. The overall rank test for each ingredient and the attributes provided a reliable data/information to select the most compatible ingredients for further optimization experiment.

Abstract

Screening of alginate lyase producing bacteria associated with seaweed Sargassum crassifolium was carried out, and isolate S245, identified as Bacillus megaterium S245 was found to produce high alginate lyase activity. This research was conducted to evaluate activity of the alginate lyase enzyme at various pHs, temperatures and substrates. Polymannuronate and polyguluronate were used to evaluate substrate specificities. Alginate lyase activity was assayed by analysis of reducing sugar released using the 3,5 dinitrosalicylic acid (DNS) method. The research showed that the activity of alginate lyase was optimum at pH of 7.0 and  temperature of 45 0C. This enzyme was active for both polymannuronate and polyguluronate susbtrates. The Vmax and Km of this enzyme for polymannuronate and polyguluronate were 200 unit/ml/min and 79.8 mg/ml for polymannuronate substrate and 27.78 unit/ml/min and 13.17 mg/ml for polyguluronate substrate. This enzyme showed unique characteristic in working toward the two substrates.

Abstract

Preservation  is  a  common  practice  in  processed  food products  including  fisheries  product.The purpose of preservation in food  is not only maintain the quality of  food but also to prolong theshelf  life  of  food  itself. Preservatives  can be  divided  into  two  groups  i.e.  natural  and chemicalpreservatives.  The  chemical  preservatives  potentially used  in  fishery  industry  are  nitrite,  sulfurdioxide,  benzoic acid  and,  sorbic  acid.  These  preservatives  have  their  own characteristics  oninhibition of microorganisms. Food characteristic such  as  pH, and aw are  the  key  factors on theactivity of antimicrobial agent.
