Abstract

Indonesia is popularly known as sea cucumber (teripang) exporter in the form of dried teripang. Commonly known as beche-de-mer or gamat, sea cucumber has long been used as medicine and food by Asian and Middle East people. Recent study  has shown that sea cucumbers contain active compounds that show potential health benefits and other biological properties such as antibacterial and antifungal products, anticoagulants, antihypertensives, immuno modulation, inhibitor of osteoclastogenesis. It was reported that sea cucumber posses aphrodisiacs, potentially improve immunity, anticancer and anticoagulation. Sea cucumber is also rich in collagen as a component of connective  tissue which can further be converted into smaller molecule and act as bioactive substances. This  review presents  the potential of sea cucumber as a functional food especially to prevent cancer and  strategy to develop sea cucumber-based functional food  by enzymatic hydrolysis and in vivo study.

Abstract

Salt is one of the most important food materials for human life. Although the total consumptionof salt increases every year, the total production decreases. Salt, in Indonesia and other tropicalcountries, is manufactured by using total crystallization system with poor quality and low quantity.The shortcomings in salt production are its low productivity and the function alteration of salt farms.Improving the quality of salt needs to be done, for example by improving technology, qualitymanagement system, trainings, and equipments. Whereas its quantity could be improved byintensification and extensification. Salt is an industrial product and an important material for otherindustries. Fish processing industry, both traditional and modern, uses salt as product processingaid. Salt preserves flavour and enhances the appearance and texture of fish meat. Salt is used intraditional processing industries, to produce dried fish, boiled fish, and fermented fish products.Whereas in modern processing industry, salt is used for the manufacture of surimi products and itsderivatives.

Abstract

Although many proteases had been studied and characterized, only a few of them are commercially available.  Protease thermostability is one of the crucial properties for industrialapplication. This research aimed to isolate and to screen the potential isolate which produce thermostable protease. There were 6 isolates (BII-1, BII-2, BII-3, BII-4, BII-6 and LII), isolated using solid Minimal Synthetic Medium (MSM) supplemented with 1.5% skim milk, that have, protease activity. Based on the 16S-rRNA gene sequencing analysis, isolates BII-1, BII-2 and BII- 6 were identified as Bacillus licheniformis, isolates BII-3 and BII-4 were identified as Bacillus subtilis, while isolate LII was identified as Brevibacillus thermoruber. Three isolates (BII-6, BII-4 and LII) were then further investigated for the second screening step using liquid MSM supplemented with 1% skim milk. The isolates (BII-6, BII-4 and LII) optimally produced protease when they were cultivated at 35, 30 and 50o C respectively after 22 h of incubation. Protease produced by BII-6, BII-4 and LII had optimum temperature  of 65, 60 and 85o C, optimum pH at 7-8, 8 and 9 and stable up to 100 min at 55, 60 and 75o C respectively.

Abstract

Indonesia merupakan negara produsen ikan tuna terbesar kelima di dunia. Terdapat  beberapa jenis ikan tuna  yang banyak diperdagangkan di pasar internasional, terutama bluefin tuna, southern bluefin tuna, bigeye tuna, yellowfin tuna, albacore, dan skipjack.  Ikan tuna termasuk komoditas yang cepat mengalami proses kemunduran mutu bila tidak disimpan pada suhu rendah dan juga dapat menghasilkan senyawa histamin yang berbahaya bagi manusia yang mengkonsumsinya. Ikan tuna segar bermutu baik dapat diperoleh dengan menerapkan teknik penanganan dan penyimpanan yang benar segera setelah ikan ditangkap. Cara penanganan ikan tuna setelah ditangkap yang sering diterapkan adalah penggancoan, pendaratan ke atas kapal, pematian, perusakan saluran saraf dengan alat Taniguchi, pembuangan darah, pembuangan insang dan isi perut,  pembersihan, serta penyimpanan dingin. Mutu ikan tuna dipengaruhi oleh faktor-faktor biologis dan non-biologis. Faktor-faktor biologis yang berpengaruh meliputi spesies, umur, ukuran, tingkat kematangan seksual, dan adanya parasit atau penyakit, sedangkan faktor-faktor non-biologis adalah metode penangkapan, teknik penanganan, teknik pendinginan, dan teknik penyimpanan.

Abstract

Streptomyces sp. TTA 02 SDS 14 is a transglutaminase producing bacteria which previously had been  screened along with more than one hundred isolates. This research aimed to purify and characterize transglutaminase from this strain. Transglutaminase was purified from crude enzyme by ultrafiltration, Q-Sepharose ion exchange chromatography and Sepacryl S200 size exclusion chromatography sequentially, obtaining yield and purification fold of  1.36%  and 27 folds, respectively. The molecular weight of the purified transglutaminase was 72 kDa detected by zymogram gel electrophoresis. The optimum temperature and pH were 50°C and 6. The transglutaminase was stable at 45°C and could be activated in the presence of 5 mM and 10 mM of Na+, K+, Li+,Ca2+, Mg2+, BPB (4-bromo-phenacyl bromide), and IAA (iodo acetamide acid), but the activity was inhibited by  the presence of Cu+, Zn2+, and PMSF (phenyl methyl sulfonyl fluoride).

Abstract

Recenty fossil fuel consumption gradually increases, resulting in decreases of its naturalresource and causing environmental problems such as air pollution and global warming.Attempts to overcome the problems have been made to create on alternative energy such asbiodiesel from jatropha, microalgae and fish oil. Biodiesel production, as matter of fact, can beconducted using industrial wastes of fish meal, fish fillets and fish canning by transesterification offish oil using methanol and alkaline catalyst. Transesterification reaction kinetics must beconsidered for an efficient process. Transesterification rate constant very much depends on thetemperature and the quantity of the catalyst

Abstract

A study on quality of jelly candy formulated from k-carrageenan and konjac (jelly powder), hasbeen conducted. The objective of this study was to determine the best ratio of k-carrageenan andkonjac in the formulation of jelly candy. The ratio of k-carrageenan and konjac was varied from40:25; 35:30; 30:35; to 25:40. The quality parameters observed on jelly candy produced were gelstrength, elasticity, stickiness, water activity (a w), and sensory test. Results showed that the bestratio of -carrageenan to konjac was 40:25 (formula A) which produced candy with physicochemicalquality closed to that of commercial one with hardness of 470.7 g, elasticity of 4.5 mm, stickinessof 36.15 g, and a wof 0.5. While the results of the sensory test showed that the difference ratio of -carrageenan and konjac had no significant effect on the product. Based on that result, the bestformulation in production of jelly candy was formula A.
