Ginger (Zingiber officinale) is a plant used in traditional medicine against different diseases because of its various properties (antimicrobial, antioxidant, anti-inflammatory, anticoagulant, etc.). Ginger is “generally recognized as safe” by the Food and Drug Administration. Numerous studies have been carried out to characterize and isolate its main bioactive compounds to elucidate the mechanisms of its antimicrobial activity against pathogenic and spoilage microorganisms in foods. Results indicate that ginger contains monoterpenoids, sesquiterpenoids, phenolic compounds, and its derivatives, aldehydes, ketones, alcohols, esters, which provide a broad antimicrobial spectrum against different microorganisms and make it an interesting alternative to synthetic antimicrobials. However, its application in foods has been scarcely explored and represents an opportunity area for further research. This review provides an updated overview of the main bioactive compounds of ginger, its potential application, and toxicity as an antimicrobial in food products.

The Refractance Window™ (RW) technique was used to dry carrot slices (3 cm diameter; 0.2 and 0.4 cm thickness) at 74 and 94°C. Moisture loss, texture, color, total polyphenol content (TPC), and antioxidant activity (AA) were evaluated as response variables and were compared with the values of a control (fresh carrot) and the slices dried via convective drying (C) at the same temperatures. The RW method produced a reduction of drying time of 26–51% (p < 0.05) when compared to convective drying. The color, TPC, and AA values for the RW treatment did not differ (p > 0.05) compared with the control. The texture values showed a difference with respect to the control for the two drying methods used. However, between the two drying methods there was no difference in the texture (p > 0.05). The results suggest that the RW technology can be used to develop products with better functional properties compared with those obtained via conventional air-drying methods.
