The aim of this research was to determine the effect of technique and types of packaging on the quality and shelf-life of yellow seasoned pindang fish. The method used was experimental method with completely randomized block design of 2 factors: packaging technique (vacuum and non vacuum) and packaging types (Polyprophylene (PP), Polyethylene (PE), and Alumunium Polyprophylene (Al-PP). Parameters observed were chemical (pH and water content), physical (value of L and 0Hue), microbial (total microbes and fungi) and shelf-life (fungi, gas formation and color change). The results showed that the technique and packaging types had a significant effect on the pH of the pindang at the 7th day.Packaging technique affected pH and L value at 7th and 14th day, while the moisture content and 0Hue differed markedly only on the 7th day. Packing types affected the pH at 7th and 14th. Vacuum packaging with Polyprophylene (PP) resulted in the lowest total microbials during storage, while the total fungus in all treatments were undetectable. Combination of vacuum packing with PP is recommended as the best treatment to produce yellow seasoned pindang fish, maintaining pH and moisture, preventing growth of fungi and microbes, as well as extending the shelf life up to the 7th day at ambient storage.</p> 2019-12-31T20:14:10+00:00 Copyright (c) 2019 Imam Budi Mulyawan, Baiq Rien Handayani, Bambang Dipokusumo, Wiharyani Werdiningsih, Astri Iga Siska Characteristic of “Bontot” Combined of Hawaiian Ladyfish (Elops hawaiiensis) Meat and Tarpon Fish (Megalops cyprinoides) 2020-01-23T08:55:29+00:00 Ipat Kasyifatul Mufarihat Sakinah Haryati Aris Munandar <em>Bontot</em> is one of fish gel products in Banten Province.

Longtail tuna (<em>Thunnus tonggol)</em> is kept in ice starting from catching process until delivering to retail market to maintain quality of fish. However, long period of this storage causes growth of bacteria and deformation of histidine into histamine. This study was aimed to determine the effect of different storage conditions to the quality of longtail tuna through sensory and histamine test. Samples of longtail tuna were kept for 18 days in room temperature storage (28±2°C), cold temperature (0±3°C) and freezing temperature (-10±4°C). The quality of tuna was evaluated using Quality Index Method (QIM). The formation of histamine was analysed on day 0, 1, 2, 3, 4, 8, 14, 18 using spectrofluorometry method. Sensory acceptability limit at room temperature was one day, while cold storage reached 10 days with QIM score 11. Longtail tuna was spoiled on day 2 at room temperature with QIM score &gt;12 and concentration of histamin at 1713.88 mg/kg. The results of histamine in frozen and cold storage on the 18th day were 59.99 mg/kg and 77.98 mg/kg, these results exceeded the FDA limit (50 mg/kg) but still below the limit of FAO (100 mg/kg).The best storage condition is frozen storage, maintaining sensory acceptability and preventing histamine formation. <br /><br /><br /> 2019-12-31T00:00:00+00:00 Copyright (c) 2020 Norita Norita, Mala Nurilmala, Asadatun Abdullah Characteristics of Chitosan from White Leg Shrimp Shells Extracted Using Different Temperature and Time of the Deasetilation Process 2020-01-23T08:55:29+00:00 Beni Setha Fitriani Rumata Bernita br. Silaban Chitosan is a white amorphous solid chitin, and of high biological and mechanical characteristics. Chitosan production is divided into two stages. First is chitin isolation (deproteination, demineralization, and depigmentation), and second is deacetylation of chitin to chitosan. This research was aimed to determine the characteristic of chitosan isolated from the shells of the white leg shrimp using different temperature and time in the deasetilation process. The FTIR test results showed that the chitin group was partially broken into chitosan in every treatment.

The Buduk had pH 5-55, moisture<br>52.35%, salt 1.96%, titrated acid 10.80%, free amino nitrogen 1.83 mmol/g, free fatty acid 17.96%, ethanol<br>0.95%, total of mesophilic bacteria 4.81 log CFU/g and lactic acid bacteria 2.09 CFU/g, but no pathogenic<br>bacteria detected. Each commercial buduk showed different physicochemical properties probably caused<br>by variation in recipe of each producer. The microbiological properties did not significantly different but the<br>TMAB found more than the threshold value indicating</p> 2019-12-31T00:00:00+00:00 Copyright (c)
