A simple method, based on oxgall tolerance, is proposed for differentiating red halophilic bacteria commonly found in solar salt and discoloured salted codfish. Tests carried out on 18 strains isolated from various sources have shown that the rod forms are inhibited by low concentrations of Bacto-oxgall and that the coccus forms tolerate relatively high ones. Bacto-oxgall can thus be used as the basis of a simple selective medium. This test has been found useful for the isolation, purification and partial identification of unidentified strains and also for determining the relative proportions of the two main types of red halophilic bacteria present in solar salt and salted fish samples.

ABSTRACT The prevalence and numbers of Listeria monocytogenes in various categories of ready-to-eat (RTE) food products taken from retail outlets and food industries over a 5-year period are presented. A total of 30,016 RTE food samples were analyzed for L. monocytogenes prevalence, and 3.6% were found to be positive. The highest prevalence was found for RTE fish and fish products (11.6%), especially for lightly salted and cold-smoked fish products. The overall prevalence of L. monocytogenes in other food categories was low, within the range of 0 to 3.9%. In addition, 14,342 RTE food samples were analyzed to determine the numbers of L. monocytogenes. A food safety criterion of 100 CFU/g was exceeded for 0.3% of RTE food samples. Samples most often exceeding the legal safety limit were from the RTE salted and cold-smoked fish product categories. High prevalence, 28.6 and 26.5%, respectively, and high numbers of L. monocytogenes among salted fish and cold-smoked fish products indicate a risk of listeriosis, especially for susceptible risk groups. The results of the current study can be used at both the national and the international levels to update the perception of the L. monocytogenes risk deriving from RTE foods. HIGHLIGHTS

The conditions for nitrite reductase (NiRs) produced by Lactobacillus plantarum from salted fish were optimized. Enzyme activity of nitrite reductase was used as evaluation index. The results showed that the pH value had greatest influence on enzyme activity. The optimum conditions of producing nitrite reductase were inoculate quantity 4 %, pH 6.3, culture temperature 35 °C, incubation time 48 h. The enzyme activity of nitrite reductase reached to 89.672 U/mL, which increased by 71 % after optimization. This work provided the foundation for the research of enzymatic properties of nitrite reductase. This may be useful to the production of salted fish products.

Tanjung Taruna Village is one of the areas in Jabiren Raya Subdistrict, Pulang Pisau Regency, Central Kalimantan province. This village is included in the peat swamp area and the Kahayan river basin. This village is geographically located in a watershed, making fishery products abundant, but the local community is constrained by marketing and processing fishery resources. Most of the population works as fishermen. This Village Development Grant Program (PHBD) activity aims to provide training and assistance to increase knowledge, skills and community welfare. The method of activity is carried out by conducting socialization, training and mentoring on the processing of fish into shredded and meatball products in order to increase the sale value of these fish which previously were only sold in the form of fresh fish and salted fish. The results of the activity showed that the participation of the participants was quite good with 38 participants. Based on the results of the training evaluation, it is known that 95.5% of the training participants have increased knowledge and can process fish products from their natural resources to be processed into fish balls and fish floss can be used as a source of household income.

The aim of the research is to develop the requirements for the consumer properties of salted fish products from fish of the South of Russia based on an analysis of consumer preferences obtained as a result of a sociological survey and determining the possibility of adjusting the color of salted fish products in accordance with the developed requirements. The objectives of the study are: development of requirements for the consumer properties of salted fish products from the fish of the South of Russia based on the analysis of consumer preferences obtained as a result of a sociological survey; selection of food colors for processing salted fish; determination of color characteristics (color formula) of salted fish colored with food dyes using the RGB color system using the FastColorPick computer program. The objects of the study are fish from the South of Russia: pilengas (Mugil so-iuy Basilewsky), silver carp (Hypophtalmichtys molitrix Val.), Common carp (Caprinus carpio), golgfish (Carassius auratus gibelio). As a result of the studies, it has been found that consumers prefer the color of salted fish products, which is similar to the color of the muscle tissue of salmonids. In order to obtain the desired color of salted fish products from the South of Russia, it is possible to color them with food dyes. An effect similar in color to that of salmon fish species has been obtained by staining the muscle tissue of the studied fish species with a 0,3% solution of E160c wig dye and 0,1% solution of neolin DR dye. As a result of treating fish with a solution of E120 carmine dye, a shade is formed that is not characteristic of the natural color of salmon fish.

Salted fish is one of the processed fish products that are in great demand by the people of Indonesia. This type of preparation has good durability with natural processes. However, there are some cases that use chemicals as preservatives, such as formaldehyde. This study aims to determine the formaldehyde content in salted fish that is traded in the market in Indonesia. This research is descriptive and the sample is taken from Ciroyom Market, Bandung City, Indonesia, randomly. Samples were analyzed qualitatively to observe the physical characteristics of salted fish. In addition, quantitative analysis was also carried out to determine the level of formaldehyde present in salted fish using a UV-Vis spectrophotometer at a wavelength of 520 nm. The results of the analysis showed that 4 of the 15 samples tested contained formaldehyde with a concentration of 0.033 – 0.482 ppm. The characteristics of these samples physically also have similarities with the characteristics of fish containing formaldehyde, namely bright white and hard textured.

The Mediterranean Sea dominated Greco-Roman society in many ways, but none more importantly than as a source of food. Early Punic settlers in the West and later Greeks and Romans, motivated by the need for long-term storage and commercial transportation of highly spoilable marine products, developed methods for salting fish that have persisted, albeit in more technically sophisticated ways, into modern times. Salted fish products took two basic forms, salt-fish (salsamentum, tarichos) and fish sauce (garum, liquamen, allec, muria). The former served as an appetite enhancer during the gustatio; the latter was the primary condiment used in food preparation and consumption. In addition, both products had perceived dietary and therapeutic value. Ancient literary, epigraphic, papyrological, and archaeological sources show that salt-fish products were produced at family, artisanal, and industrial levels and played a significant role in long-distance trade. Greeks and especially Romans, for whom evidence is more plentiful, established processing centers at places on the Atlantic and Mediterranean coasts, including in some urban areas, that offered sources for fresh water, salt, and fish, particularly pelagic species. Extant remains of fish salteries (cetariae), especially in Spain, North Africa, and the Black Sea, display consistent patterns of vat construction, arrangement, and operation that imply a common origin for the salting process. The most active period of production of and commerce in salted fish occurred between the 1st century bce and the 3rd century ce, with some installations active into the early 6th century ce.
