In this study, ochratoxin A (OTA) occurrence in Argentinean musts, wines and dried vine fruits was evaluated, alongside with the performance of OchraStar(TM) columns for OTA extraction. In all the three matrices analyzed, the OchraStar(TM) columns showed good performance. The analysis of natural occurrence of OTA in the red must and the red wine samples showed low incidence with low levels of m...

This study performed physical, chemical, and microbiological analyses to determine the best formulation shelf life of a new additive-free Mediterranean diet product. The spreadable creamed product was formulated with roasted peanut (32%) hazelnut mixed, sweetened dried grape (15%) sun-dried apricot (15%). Different storage temperatures as 25 oC, 35 45 oC were used for prediction accelerated she...

The antimicrobial effects of red wine and its inherent components on oral microbiota were studied by using a 5-species biofilm model of the supragingival plaque that includes Actinomyces oris, Fusobacterium nucleatum, Streptococcus oralis, Streptococcus mutans and Veillonella dispar. Microbiological analysis (CFU counting and confocal laser scanning microscopy) of the biofilms after the applica...

Resveratrol, trans-3, 5, 4’-trihydroxy stilbene is a naturally occurring phytoalexin present in many different types of nutrients which we consume on daily basis. Resveratrol was first isolated from dried roots of Polygonum cuspidatum, as the principal active ingredient. Polygonum cuspidatum and its extract have been used in Japanese and Chinese traditional medicine for treatment of various ski...

AIM To determine the effect of two different extracts of red maca in male rats. METHODS Prostatic hyperplasia was induced in male rats with testosterone enanthate (TE). The study comprised six groups: one control group (group 1), one group treated with TE (group 2), two groups treated with TE and aqueous extract of red maca (groups 3 and 4), one group treated with hydroalcoholic extract of re...

Two innovative soft maceration techniques of vinification based on red grape Cabernet Sauvignon were compared in 2020 and 2021 vintages with the most used system (pump-over delestage) today’s wine sector order to verify efficiency polyphenol extraction fermentation rate. Fermentation kinetics final characteristics evaluated as main parameters for comparing systems. The AIR MIX (AIRMIXING M.I.™)...

The aim of this work was to determine the effect different drying treatments: freeze-drying, room-drying, and oven-drying on grape phenolic composition 'Regent' 'Cabernet Sauvignon' varieties. After drying, samples were grounded, submerged ultrasound-assisted extraction, analyzed with high-performance liquid chromatography (HPLC). This study demonstrated that use methods significantly affects c...
