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,

Optimization of pressure parboiling conditions and pre-conditioned moisture content of brown rice (unpolished rice) for microwave puffing and its comparison with hot sand bed puffing

Brown rice puffing (unpolished rice) gives a more nutritious product compared to traditional puffed polished rice and reduces the cost of the product significantly, even though, the rice bran layer resists expansion during puffing. In the present study, brown rice was puffed in a microwave and hot-sand-bed after its pressure parboiling. Pressure parboiling parameters, steam pressure (196, 294, 392, 490 kPa) and steaming time (5, 10, 15 min), along with pre-conditioned moisture content (8, 10, 12 % wb) were studied and optimized for puffing characteristics (puffing percentage, expansion ratio, whiteness index, bulk density and hardness). All the experiments were carried out using a full factorial design. Statistical analysis showed there was a significant effect of processing variables on puffing characteristics. Optimized steam pressure, steaming time and pre-conditioned moisture content for microwave puffing were found to be 303.6 kPa, 14.25 min and 11.6% (wb) respectively, and for hot-sand-bed puffing to be 260.7 kPa, 15 min and 8% (wb) respectively.

Popping characteristics of paddy using microwave energy and optimization of process parameters

Microwave popping characteristics of a particular variety of paddy were studied using a domestic microwave oven. The experiments were carried out at 4 levels of moisture content (around 13%, 14%, 15% and 16% wb), 3 levels of power (600 W, 850 W and 1000 W) and 5 levels of heating time (40 s, 60 s, 80 s, 100 s and 120 s). A general factorial experiment design was followed, and effect of different treatment combinations on popping percentage and expansion ratio of the paddy was evaluated. The maximum popping percentage of 63.47% was obtained at a moisture content of 14.15% and energy level of 80 kJ (1000 W and 80 s) while the maximum expansion ratio of 4.42 was obtained at 14.94% moisture content and energy level of 68 kJ (850 W and 80 s). Optimum values of microwave power, time of heating and moisture content of paddy were achieved at 1000 W, 80 s and 15%, respectively, corresponding to popping percentage and expansion ratio of 58.73 and 3.58.
