Abstract

Kecalokis recognized as a typical shrimp sauce traditionally produced by the Malay inhabitants in Bangka Island and Palembang, Southern region of Sumatra. Comparing to terasi, the most common Indonesian fermented shrimp, the information on kecalokhas rarely been reported. This study aimed to obtain the characteristics of both the geographical origin of kecalokproduct from Bangka and Palembang. A descriptive analysis was used to observe the profiles of both kecalokproducts including sensory, microbiology, proximate, and physical analysis. Results showed that kecalokfrom both locations had similar characteristics, i.e. a distinctive taste and aroma, high nutrition value, and containing some useful bacteria (LAB) which have beneficial role in human body. Therefore, kecalokwill be a prospective functional based-indigenous food in Indonesia.

Abstract

Peptones from fish waste has been widely studied, however information about its shelf life is stilllimited. This study aims to test the storability of dried peptone from tuna and shrimp waste produced through hydrolysis using alcalase enzyme. Peptone powders were packed in HDPE plastic bottles and plastic coated aluminum foil, stored at room temperature, and periodically observed in quality (moisture content, aw, color and appearance). A test was also performed on their ability to support the growth of Staphylococcus aureusbacteria; all were compared to commercial peptone (Difco). Shrimp waste peptone had the highest moisture, ash calcium contents, while tuna peptone has the highest fat content. During five month storage at ambient temperature, all peptones experienced a slight decrease in quality. Aluminum foil performed better than HDPE bottles as a packaging material for peptones, i.e., able to maintain the moisture content, water activity, and appearance. Although the ability to support bacterial growth after five months of storage was slightly affected, the tested peptones were still able to beused as bacterial growing media. It can be concluded that fish waste peptones had comparable quality and shelf-life atambient temperature to commercial peptone.

Abstract

Protease enzyme produced from Bacillus sp was employed to hydrolyze fish protein hydrolysates (FPH) under controlled conditions at a batch-pilot plant scale-process. Thirty kilograms of fish meat was mincedand mixed with 60 liters of water in 100 liters stainless steel vessel and 20,000 units of protease enzyme was added per kg of fish. Hydrolysis of fish was carried out at 55 oC for 6 hours. Multi stage of filtration were done to separate the FPH from unhydrolized fish residue. Mass balance were carried out to determine the rate of hydrolysis and yields. W ithout pH adjustment, 80% of substrate hydrolyzed could be achieved in 6 hour at 55 °C. Three kinds of products were recovered from the process, i.e solid residue, liquid FPH as filtration product, and spray dried FPH. Hydrolysis of 30 kg of fish meat substrate producing 1.7-2.0 kg of unhydrolyzed residue and 70 L of liquid FPH. Afterspray drying process of liquid FPH, 13 kg of FPH powder was recovered. The proximate and amino acid analysis of spray dried FPH showed that the FPH containing 20% of protein, rich in amino acids especially lysine and leucineand the residue still had 85,36% of protein (dry basis) that could be utilized for other purpose.

Abstract

Alkali treated cottonii (ATC) is a derivative product of Eucheuma cottoniithat is treated with alkali. This study used raw material of sap-free seaweed for ATC processing. Sap-free seaweed is a seaweed which thallus has been extracted with liquid known as sap. The use of sap-free seaweed as an ATC product is constrained by its low quality, so an effort to improve its quality is needed. Therefore the obejcetive of this Research was to get the optimal conditions of ATC processing. Experimental data were designed and analyzed using Response Surface MethodologyCentral Composite Design (RSM-CCD) using Design Expert 10.0.7® program. The optimization of ATC processing involved three components that were considered influential, namely KOH concentration, temperature, and processing time. Recommendation for optimal conditions issued by RSM-CCD on ATC processing from sap-free seawee d were 6 % KOH concentration at 75 oC for 120 minutes (93.1% desirability). The results of the response analysis showed a yield of 39.47% and a gel strength of 595.32 g/cm2. As a research control, the recommendation of RSMCCD used in ATC processing from nonsap-free seaweed was obtained yield of 36.81% and gel strength of 574.44 g/cm 2. ATC from sap-free seaweed has higher yield and gel strength than that from nonsap-free seaweed. Thismight be due to the sap-free seaweed was obtained using the proper sap extraction process and ATC processingunder optimal conditions, so that the quality of seaweed was better maintained.

Abstract

This study aimed to evaluate the potential antibacterial and antioxidant activities of Sinulariasp. and Sarcophyton sp. from the Palu Bay, Central Sulawesi, Indonesia. Soft corals were identified as Sinulariasp. (SC1), Sinularia sp. (SC2), andSarcophytonsp. (SC3). Antibacterial activity was examined using agar diffusion well method. Antioxidant activity was measured by the DPPH radical scavenging method. The samples were macerated in MeOH: DCM. The crude extracts were partitioned with DCM, EtOAc, and BuOH. The crude extract of Sinulariasp. (SC2) showed a very strong antibacterial activity as it was able to inhibit the growth of Staphylococcus aureusand Escherichia coliup to 10 mg/mL. Sinularia sp. (SC1) crude extract showed strong activity againstS. aureus, whereas it showed moderate against E. coli.Sarcophyton sp. (SC3) crude extract showed moderate activity against S. aureus, whereas it showed weak against E. coli. The partition fractions of the three soft coral extracts had the potential to be a potent antioxidant agent.
