Highlights
- High microbial loads were detected in fresh ascomata of black summer truffles collected from Central Italy.
- Pseudomonas spp. and lactic acid bacteria were present at the highest levels.
- Common brushing procedure applied for preparation of truffles is not sufficient to eliminate microbial risks.

Highlights
- Drying temperature had significant effect on drying time, acidity, and peroxide values of hazelnuts.
- The lowest acidity and peroxide values were recorded for the samples dried at 60 °C with the values of 0.15% oleic acid and 1.3 meq/kg, respectively.
- Sensory results showed that all of the treated hazelnuts were acceptable after six months storage.
- In-shell hazelnuts drying at temperature of 60 °C can lead to production of good quality products.

Highlights
- Interaction of acids (hydrochloric acid and acetic acid), and drying methods (oven and freeze drying) significantly (p<0.01) affected chemical profile of sodium caseinate.
- The kinds of acid and drying methods altered the moisture, protein, and ash content of sodium caseinate.
- The combination of hydrochloric acid and freeze drying can produce good chemical characteristics of sodium caseinate.

Highlights
- Anti-Brucella activity of Cinnamon zeylanicum essential oil was significantly more than that of Myristica fragrans.
- Due to the appropriate anti-Brucella activity, C. zeylanicum essential oil could be applied in production of Baladi cheese.
- Using M. fragrans essential oil could not protect the fresh Baladi cheese against Brucella.

Highlights
- All Essential Oils (EOs) of Zataria multiflora, Mentha pulegium, and Mentha piperita showed antifungal activities.
- Among three studied plant EOs, Z. multiflora EO showed the strongest antifungal activity.
- Inhibition zone of Z. multiflora EO for Aspergillus spp., Penicillium spp., and Geotrichum candidum were 11.6, 5.7, and 7.1 mm, respectively.

Highlights
- No statistically significant DNA damage was observed in B lymphocytes treated with Zataria multiflora extract.
- The comet assay used in the current study showed that Z. multiflora had no genotoxic effect.
- More studies are recommended to examine the safety of plant extracts used as food preservative.
