This article reports the development of a beer made with Baccharis dracunculifolia and its application in an experimental model of diabetes. Initially, the production of the beverage was standardized in order to incorporate the plant extract properly. Next, the beer was analyzed by the UHPLC-MS to identify the substances present.

Kombucha is a trending tea fermented via a complex microflora of yeasts and acetic acid bacteria. It can be a valid low-calorie substitute for soft drinks due to its sour, naturally carbonated, and sweet taste. Despite increased interest, the microflora and functional properties of kombucha have not yet been fully understood.

In this work the impact of an innovative protein stabilization method (TiO-based composite sorbent material coupled with a prototype device operating under continuous flow) has been tested in terms of protein and oxidative stability of white wines. Optimal process parameters (duration 60 min; flow rate 1.5 ± 0.

Article Synopsis
  • * A partial least squares regression (PLSr) model was developed, yielding decent predictive performance with an R value of 0.630 and a root mean square error (RMSE) of 0.994, using 19 significant independent variables.
  • * Key variables influencing astringency, such as Procyanidin B1 and Epicatechin, were identified, providing insights into the chemical factors that contribute to the sensory perception of astringency in red wine.

In sparkling winemaking, only a few yeast strains are regularly used for the secondary in-bottle alcoholic fermentation (SiBAF). Recently, advances in yeast development programs have yielded new breeds of interspecific wine yeast hybrids that ferment efficiently while producing novel flavors and aromas. In this work, the chemical and sensorial impacts of the use of interspecific yeast hybrids for SiBAF were studied using three commercial English base wines prepared for SiBAF using two commercial and four novel interspecific hybrids.
