The development of innovative technologies, promoting fruits and vegetables safety to reduce the risk of related food-borne diseases, is an actual concern. Several sanitizing agents for washing fruits and vegetables may be used to reduce the risk of microbial contamination. Traditional washing technologies utilize chlorine and hydrogen peroxide as sanitizing agents for fresh produce. More recently, ozone is bei...
The objective of this work was to study the effect of ultrasonication, thermosonication and UV-C irradiation on the quality attributes of strawberries (Fragaria anannassa) and red bell peppers (Capsicum annuum, L.). Thermosonication studies were carried out at 50ºC and 65ºC. Control water treatments at the same temperatures were conducted. The analysed quality factors were colour and texture for both products, ...
Innovative non-thermal technologies have been studied as an attempt to substitute thermal methods on fruits and vegetables processing. The objective was to study the effect of methods, such as ultrasonication, and its combination with a milder heat treatment (thermosonication), and UV-C irradiation on safety of strawberries and watercress. Thermosonication studies were carried out at 50ºC, 55ºC, 65ºC and room t...
