Pulsowo-różnicowa woltamperometria jako narzędzie pozwalające na wyznaczenie wartości mocy przeciwutleniającej
PublicationStandardowy potencjał redukcji (E0) jako parametr określający zdolność przeciwutleniaczy, jak np. flawan-3-oli do przyjmowania elektronów wykazywał wysoką korelację z ich aktywnością biologiczną. Jednak, w przypadku oceny całkowitej aktywności przeciwutleniającej mieszanin tych związków, parametr ten może okazać się być niewystarczającym. Bowiem do określenia tzw. mocy przeciwutleniającej ang. antioxidant power (AOP) powinny być...

The impact of thermomechanical and chemical treatment of waste Brewers’ spent grain and soil biodegradation of sustainable Mater-Bi-Based biocomposites
PublicationDue to the massive plastic pollution, development of sustainable and biodegradable polymer materials is crucial to reduce environmental burdens and support climate neutrality. Application of lignocellulosic wastes as fillers for polymer composites was broadly reported, but analysis of biodegradation behavior of resulting biocomposites was rarely examined. Herein, sustainable Mater-Bi-based biocomposites filled with thermomechanically-...

Discrimination of Apple Liqueurs (Nalewka) Using a Voltammetric Electronic Tongue, UV-Vis and Raman Spectroscopy
PublicationThe capability of a phthalocyanine-based voltammetric electronic tongue to analyze strong alcoholic beverages has been evaluated and compared with the performance of spectroscopic techniques coupled to chemometrics. Nalewka Polish liqueurs prepared from five apple varieties have been used as a model of strong liqueurs. Principal Component Analysis has demonstrated that the best discrimination between liqueurs prepared from different...

More than just a beer – Brewers' spent grain, spent hops, and spent yeast as potential functional fillers for polymer composites
PublicationBeer is among the most popular beverages in the world, with the production distributed uniformly between the biggest continents, so the utilization of brewing by-products is essential on a global scale. Among their potential recipients, the plastics industry offers extensive range of potential products. Herein, the presented study investigated the application of currently underutilized solid brewing by-products (brewers' spent...

Principles of smoking
PublicationTreatment of a large variety of foods with wood smoke has been practiced for centuries—predominantlymeats, poultry, and fish, but also scallops, cheeses, prunes, paprika, and themalt used to produce whiskey and some sorts of beer.The process usually includes salting and partial drying; it may also be coupled with heating. The aim is to increase the shelf life of the products, prevent food poisoning, and add a desirable smoky flavor....

Smoking: Traditional
PublicationSmoking, drying, and salting belong to the oldest methods of food preservation. Meat hung by the fire was preserved by a combination of drying and smoking. Often the raw material was first pickled in brine. In different regions of the world various procedures have been developed, best suited for treating meats and fish for specific purposes. Smoking extended the shelf life and imparted very desirable, new sensory properties to...
