Fermentation is an important tool in producing functional beverages through agro-industrial wastes, and medicinal and aromatic plants due to the specific content of bioactive molecules. Therefore, this study evaluated the contribution of (chamomile), (lemongrass), or (peppermint) extracts to the phytochemical profile and potential biological effects of a functional fermented orange beverage in vitro and in silico. The concentrations of aromatic herbal extracts that yielded the best sensory performance for fermented beverages were selected for analyses that involved characterizing the fermented beverages.

Consumers increasingly prefer and seek functional beverages, which, given their characteristics, provide important bioactive compounds that help prevent and treat chronic diseases. Mead is a traditional fermented alcoholic beverage made from honey solution. The aging process of mead with oak chips is innovative and bestows functional characteristics to this beverage.

Unlabelled: Anthocyanins are important compounds in grapes and wine and significantly influence their characteristics. Ultraviolet light-C (UV-C) can be used as a tool to induce secondary metabolism, and in this study, it was used in 'Cabernet Sauvignon' grapes in the postharvest period to improve the anthocyanin profile and sensory attributes in wine produced with irradiated grapes. Grapes in the postharvest period were exposed to 0, 2, or 3 kJ m UV-C radiation.

This study investigated the dynamic changes in the anaerobic metabolism end products (ethanol, acetaldehyde and ethyl acetate) of different apple cultivars during 84-days of regular air (RA) and controlled atmosphere (CA) storage after 0-, 3-, 7- and 14-days of anoxia. Increasing the length of exposure to anoxia increased the anaerobic metabolites concentrations (AMC) in all cultivars. Fruit could recover from anoxia, and the AMC dissipated after 84-days of storage under both storage systems when the duration of anoxia was <7-days.

Persistent organic pollutants are characterised by their chemical structure, environmental persistence and toxicity to human and wildlife populations. The production of these chemicals is regulated and restricted. However, they continue to be detected in the environment.

Article Synopsis
  • * Acute consumption of both juice and wine reduced glycemia and plasma lipid peroxidation, while juice also decreased uric acid levels, unlike wine which increased them.
  • * Juice was found to enhance cell viability and reduce oxidative stress in neuron-like cells, while dealcoholized wine had the opposite effect, suggesting that grape juice has more protective benefits against oxidative damage.

Ultraviolet light type C (UV-C) was studied as a tool to increase enzymatic and non-enzymatic antioxidant defenses and phytochemical levels in 'Isabel' grapes (Vitis labrusca×Vitis vinifera L.). Grapes were exposed to 0, 0.

Thermal pest control (TPC) is a technology that applies heated air in the vineyard to reduce pests. However, it can also alter grape anthocyanin synthesis in answer to temperature stress. The aim of this work was to determine the impact of TPC in 'Tannat' grape vineyards on wine quality.

Currently, Rio Grande do Sul state is the main producer of blueberry in Brazil. Practically all production is commercialized in fresh state and only a small portion is subject to processing. The blueberry wine making process is an alternative to expand the beverage industry and offers to the consumer a value-added product as well as a new market for Brazilian blueberry producers.
