Active packaging films with natural antioxidants to be used in meat industry: A review.
Spoilage of meat products during processing, distribution and exposure in the markets have an important negative impact on meat industry from an economic point of view. Two of the main problems of meat and products during processing and subsequent storage are lipid oxidation and deterioration due to microorganism growth. In this context, several packaging alternatives have been developed by meat industry in order to limit these losses and to extend the meat products´ shelf life. Over the last years, the use of active packaging has been proposed as an alternative to traditional packaging. The principle of active packaging, particularly antioxidant active packaging, consists of including acti…
Biosensors Applied to Quantification of Ethanol in Beverages
Abstract The quality control in the processing of alcoholic beverages is major concern for producers and regulatory agencies, particularly for ethanol content which is mandatory in the label of alcoholic beverages in many countries. The use of biosensors can be of great interest in this context that usually requires laborious and costly protocols. Biosensors are composed by two principal components: the biological recognition element and the transducer. Particularly for ethanol evaluation, the use of alcohol dehydrogenase (ADH) or oxidase (AOX) is commonly reported in the literature which allowed the production of optical and electrochemical biosensors. These biosensors can aid in the deter…
