A pandemic is not a new event encountered in the history of humanity, because mankind has faced various pandemics in history. The common point of pandemics is their serious negative effects on the global economy. Considering the food supply chain, one of the most important sectors of the economy, it has seen that COVID-19 has an impact on the whole process from the field to the consumer. In the light of recent challenges in food supply chain, there is now considerable concern about the food production, processing, distribution, and demand. COVID-19 resulted the movement restrictions of workers, changes in demand of consumers, closure of food production facilities, restricted food trade policies and financial pressures in food supply chain. Therefore, governments should facilitate the movement of workers and agri-food products. In addition, small farmers or vulnerable peoples should be supported financially. Facilities should change the working conditions and maintain the health and safety of employees by altering safety measures. Food protectionist policies should be avoided to prevent an increase in food prices. In conclusion, each country must realize the severity of the situation and sometimes should tighten or loosen the measures according to spreadability of the pandemic. The supply chain also should be flexible enough to respond to the challenges in the food supply chain. The purpose of this review article is to determine the impact of COVID-19 in the agriculture and food sector and to summarize the recommendations required to reduce and control the effect of the pandemic.

Mihalic is a hard, brined and quite salty cheese. In this study, selected physical, chemical, and sensory properties of 15 Mihalic cheese samples (matured more than six months) in vacuum packaging were investigated using representative samples collected from its major production area in northwestern Turkey. Aroma-active compounds were analyzed by solid phase microextraction and determined by gas chromatography-olfactometry. Average dry matter and fat contents of the cheese were 60.4 and 27.4 g/100 g cheese, respectively. Significant differences were observed among the cheese samples for hardness, adhesiveness, chewiness, and gumminess. Sulfurous, free fatty acids, and barny/animal were major sensory descriptors for the cheese. Methional (boiled potato), (E,E)-2,4-nonadienal (fatty, stale), diacetyl (buttery), 1-octen-3-one (mushroom), ethyl butyrate (sweet, bubble gum), and butyric acid (rancid) were common aroma-active compounds found in Mihalic cheese.

High Hydrostatic Pressure Processing (HPP) has gained more attention in the fruit and vegetable industry in recent years. In this study, the optimal acidification parameters (citric acid alone and combination with ascorbic acid at the pH range 3.0 to 4.5) were determined and the effect of HPP conditions (pressures 250-450 MPa and exposure times 1-5 min) on acidified liquorice root sherbet (ALRS) were investigated. Results showed that acidification of LRS by only citric acid had higher aroma and flavor scores. HP treatments were effective to reduce the yeast and mold (YM) count, total coliforms (TC), and inoculated pathogens (Escherichia coli ATCC 25922 and Salmonella Typhimurium ATCC 14028) in ALRS. Although acidification of LRS achieved a significant reduction in glycyrrhizic acid (GA) content, further treatment by HPP did not affect pH, the contents of total phenolic, total soluble solids, flavonoid, and GA or the antioxidant capacity of ALRS. Our results suggest that acidification and HPP treatments could be used to increase consumer acceptability and extend the shelf life of LRS.
