Dear Readers,

It is a privilege to introduce our first 2024 issue (Vol 13) of the International Journal of Food Studies.

The journal mission was again well addressed, with a diverse research authorship and a stimulating discussion in the area of food education, food research and innovation.

The consumer was one of the main themes through this issue:

  • Guo presented an analysis of the power of media to shape consumer attitude towards meat alternatives and the opportunities that policy makers have in this area.
  • Un Nisa et al studied the quality assessment of a strawberry juice with prebiotic fibre processed with ultrasound, showing how ultrasound processed samples obtain higher scores in sensory acceptability.
  • Acella and colleagues aimed to enhance the knowledge on the perception of quality by consumers of short food supply chain products, with 20 case studies of SFSCs across Europe. Social characteristics of the products such as genuineness were seen as major criteria.

A second main topic in this issue was shelf life:

  • Andriani et al studied a traditional Indonesian fish shelf life demonstrating that vacuum packing and salt may contribute to extend the short shelf life of this product.
  • Susantia and Kristamtini assessed in vivothe ability of black garlic extracts to maintain blood sugar homeostasis as well as reducing low density lipoprotein levels and increasing the high density lipoproteins.
  • Haddad and Bani-Hani assessed the ability of protective cultures to extend the shelf life of Labaneh, a traditional dairy product from Jordan. 
  • Duc Vu and colleagues presented an analysis of the efficiency of the commercial production of dried Segestid shrimp studying losses and bringing a better understanding of the production of this traditional Vietnamese product.

Finally, food and health was the third underlying theme, where:

  • Najat and colleagues discussed the issue of brucellosis in dairy farms in Morocco, identifying a number of knowledge gaps in farmers and potential risks associated.
  • Hernandez et al. presented a study highlighting the need to characterise liquids for dysphagia patients and the importance of rheology in these preparations.
  • Hasain et al. findings included that energy drinks available in Kosovo may exhibit higher concentrations of caffeine than those levels declared in the label, highlighting the need to potentially secure the food safety and integrity of these products.

I would like to thank all the authors for their contributions, all the Editorial Board who continue to offer their voluntary work to this publication, the journal office that makes possible this issue and (last but not least) the Iseki Association support of the International Journal of Food Studies.

I wish you all a good reading.

Best regards,

Effect of Fermentation Time on Nutrition Content, Physical Properties, pH, Amino Acids, Fatty Acids Composition and Organoleptics on Fermented Mackerel Sausage (Rastrelligerkanagurta Cuvier) Characteristics

Fermentation increases the functional value of food. During fermentation, chemical changes occur in organic substrates, such as carbohydrates, proteins, and fats due to enzyme activities of microorganisms. Functional foods containing unsaturated fatty acids are an alternative for preventing cardiovascular disease. The Indian mackerel (Rastrelliger kanagurta Cuvier) is rich in protein, polyunsaturated fatty acids, and non-essential and essential amino acids. Fish that are processed into sausage and fermented can be used as an alternative functional food to prevent cardiovascular disease. This study analysed the effect of fermentation time on nutritional content (carbohydrate, protein, fat, water, ash, amino acid, and fatty acid contents), physical properties, pH, and organoleptic properties in fermented mackerel sausage. This was a completely randomized experimental study with three fermentation times of 1, 2, and 3 days, and 0 days as a control. Fermentation was carried out spontaneously with 1.9% salt and sugar without adding a bacterial culture. The drying temperature was 50oC for 3 hours, and the fermentation temperature was 35oC. The fermentation duration of mackerel sausage affected the nutritional contents (carbohydrates, protein, fat, water, ash, amino acids, and fatty acids), physical properties (hardness and chewiness), pH, and organoleptic properties (colour, aroma, taste, and texture). Overall, the longer the fermentation time, the higher the carbohydrate, protein, fat, total ash content, total amino acid, total fatty acid, hardness and decreased organoleptic (colour, aroma, taste, texture), elasticity, and water contents. The best formulation for fermented mackerel sausage was 1 day of fermentation time.
