During the processing of mackerel narezushi, the fish body was strongly dehydrated by permeation of salt, the low pH of fish meat, and pressure applied to the fish and rice mixture. In the proximate components, moisture, protein and lipid flowed out from the fish meat into the rice mixture, and sugar permeated from the rice mixture into the fish meat. That the total amount of outflow was larger than that of permeation into the fish is thought to contribute to the decrease in fish body weight…

Microbial and chemical properties of aji-no-susu, a traditional fermented fish with rice product in the Noto Peninsula, Japan
Results in this study indicate that aji-no-susu is a typical traditional lactic-acid-fermented fish product.
Effect of extracts from narezushi, a fermented mackerel product, on cholesterol metabolism in Wistar rats
Both the increase in cholesterol and bile acid fecal excretion and the promotion of cholesterol 7α-hydroxylase activities are related to the hypocholesterolemic effects of narezushi extract.
Characterization of Fermented Rice Bran from 'Heshiko' and Isolation of Amylase-Producing Bacteria
In this study, we characterized the main properties of the fermented rice bran around mackerel in the Japanese product Heshiko. We found increases in the moisture, lipids, and ash contents after
Effect of cooking temperatures on protein hydrolysates and sensory quality in crucian carp (Carassius auratus) soup
A cooking temperature of 85 °C was preferred for more excellent flavor and higher nutritional value of crucian carp soup.
Effect of extracts from heshiko, a fermented mackerel product, on cholesterol metabolism in Wistar rats
Both excretion of cholesterol and bile acid to feces and promotion of cholesterol 7α-hydroxylase activity are related to the hypocholesterolemic effects of heshiko extract and that both peptides and amino acids contribute to that effect.
The influence of douchi starter cultures on the composition of extractive components, microbiological activity, and sensory properties of fermented fish pastes.
It is indicated that douchi as a novel starter can be used to produce fermented silver carp fish pastes with excellent flavor and consumer acceptability and the results may be applicable to other fish species to produce similar fermentation products.
Changes in chemical and sensory properties of migaki-nishin (dried herring fillet) during drying.
The results suggest that during the drying period, proteolysis as well as Maillard reaction products increased markedly, which might contribute to the characteristic taste and flavor of migaki-nishin.
Taste producing components in fish and fisheries products: A review
The extractive constituents, which are known as taste active components of fisheries products in many research works have been reviewed, found glutamate, glycine, alanine, arginine, proline, valine, methionine, phenylalanine, tyrosine, inosine 5’-monophosphate (IMP), adenosine, guanosine, lactate, succinate as important contributors to the taste of raw and processed fisheries products.
Extension of shelflife of the fermented fish product, shidal by packaging in glass bottle and low temperature storage
Shidal is a very popular, salt free, semi-fermented traditional fish product of north-east India prepared using minor carps ( Puntius spp.) in specially designed earthen pots (mutka). The prime


Changes in Free Amino Acid, Organic Acid, and Lipid Compositions of Fermented Mackerel "Sushi" during Processing.
Changes in free amino acid, organic acid, and lipid compositions of fermented mackerel Scomber japonicus “sushi” during processing were investigated, while commercially available fermented mackerel
Teste on the solutions from which some of the components were eliminated in a group indicated that amino acids and nucleotides are responsible for the taste and other groups, organic bases, organic acids and glucose, make little contribution, if any.
Antihypertensive effect of heshiko, a fermented mackerel product, on spontaneously hypertensive rats
During the fermentation of mackerel to narezushi, the concentration of peptides required to inhibit 50% of the ACE activity in the assay media (IC50) was remarkably decreased with a rapid increase in peptide contents.
A rapid method of total lipid extraction and purification.
The lipid decomposition studies in frozen fish have led to the development of a simple and rapid method for the extraction and purification of lipids from biological materials that has been applied to fish muscle and may easily be adapted to use with other tissues.
