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,

Microbial quality and shelf life prediction of vacuum-packaged ready to eat beef rounds containing gum arabic

Research has shown that gum arabic from Acacia Senegal var. kerensis can be used in beef rounds, at a level of 2.5% of the formulated product weight, as a binder and texture modifier. However, the effect of gum arabic addition on the microbial quality and shelf life of the resulting meat product has not yet been reported. Thus, the objective of this work was to study the microbial quality of beef rounds containing 2.5% gum arabic and to study shelf life based on the growth parameters of Total Viable Counts (TVC) and Lactic Acid Bacteria (LAB). Beef round samples were injected at 30% with curing brines containing gum arabic and cooked through boiling. The growth kinetics of LAB and TVC were studied for vacuum packaged sliced beef round samples stored at 7 °C and 15 °C for a period of 21 days. Baranyi and modified Gompertz models were used to fit the LAB and TVC data obtained using DMFit. Results of microbial analysis indicated that coliforms, yeasts and molds as well as pathogenic bacteria; Salmonella, Escherichia coli, and Staphylococcus aureus, were below detection limit. In addition, TVC and LAB were found to be 1.87 ± 1.09 and 1.25 ± 0.75 Log10 CFU g−1 , respectively. The results of accuracy analysis showed that both the Baranyi and modified Gompertz models were adequate in representing the bacterial growth in beef rounds injected with curing brines containing gum arabic. The predicted shelf life was found to be between 84.3 – 88.1 h and 158.0 – 173.1 h at 15 °C and 7 °C, respectively.
