Received: 15 July 2019; Accepted: 6 September 2019; Published: 9 September 2019 Abstract: A rapid and accurate determination method for total phenolic content is of great importance for controlling the quality of wine samples. A promising potentiometric detection approach, based on permanganate ion fluxes across ion-selective electrode membranes, is fabricated for measuring the total phenolic content of wine. The results show that the presence of phenols, such as gallic acid, leads to a potential increase for the potentiometric sensor. Additionally, the present sensor exhibits a linear potential response with the concentration range from 0.05 to 3.0 g/L with a detection limit of 6.6 mg/L calculated using gallic acid. These sensors also exhibit a fast response time, an acceptable reproducibility and long-term stability. These results indicate that the proposed potentiometric sensor can be a promising and reliable tool for the rapid determination of total phenolic content in wine samples. Keywords: potentiometric; total phenolic content; wine; indicator 1. Introduction Worldwide, wine consumption decreases the risk of cardiovascular disease and some cancers [1]. There is evidence that the presence of different phenolic substances, specifically those richly present in wine, might contribute to these biological effects on human health and disease prevention [2,3].

Brodnicka), [email protected] (M. Szpakowska) Received 15 April 2020; Accepted 2 July 2020 abstract The quality of wines resulting from vineyard management is important for consumers due to the taste and price of wines. In this work, the quality of red wines of three vintages has been inves- tigated by potentiometric sensors with six all-solid-state electrodes. Two series of experiments were carried out. The first involved a qualitative analysis of wine of different vintages from freshly opened bottles. The second consisted of measurements on wine samples of different vintages that had been in contact with air for 15 min every day during 15 or 21 d. This sensor is characterized by good sensitivity to malic acid solutions of different concentrations. The polyphenol content and organoleptic acidity of red wines from different vintages have been established. The older the wine, the more polyphenol compounds it contains. The same sequence of polyphenol content can be observed in wine samples of different vintages that had been in contact with air for 15 min every day during 21 d. The samples of wine from freshly opened bottles from 2013 were more acidic than the wines between 2012 and 2014.

  • The Impact of Optical Berry Sorting on Red Wine Composition and Sensory Properties
    foods Article The Impact of Optical Berry Sorting on Red Wine Composition and Sensory Properties Robert C. Bruce, Pauline Lestringant, Charles A. Brenneman, Hildegarde Heymann and Anita Oberholster * Department of Viticulture and Enology, University of California, Davis, CA 95616, USA; [email protected] (R.C.B.); [email protected] (P.L.); [email protected] (C.A.B.); [email protected] (H.H.) * Correspondence: [email protected]; Tel.: +1-530-752-0380 Abstract: The impact of optical berry sorting was investigated using Grenache, Barbera, and Cabernet Sauvignon grapes from Yolo County, California in 2016. Optical sorting parameters were adjusted to remove underripe berries and material other than grapes using color parameters. Wines were made from three treatments, control (no sorting), sort (accepted material), and reject (material rejected by the optical sorter). The rate of rejection was approximately 14.9%, 3.9%, and 1.5% (w/w) for Grenache, Barbera, and Cabernet Sauvignon, respectively. Chemical composition in the finished wines was analyzed by the Adams-Harbertson assay and reversed-phase high-performance liquid chromatography for phenolics, and head-space solid-phase microextraction gas chromatography mass spectrometry for aroma profiling. In general, optical sorting was successful in removing underripe berries and material other than grapes as evidenced by lower ethanol levels and higher concentrations of total phenolics and tannin (due to the inclusion of material other than grapes) in wine made from rejected material. Despite this, no difference in final ethanol content and minimal differences in phenolic composition were observed between control and sort treatment wines for the three varieties studied. Differences were observed in the aroma profiles of the reject treatments Citation: Bruce, R.C.; Lestringant, P.; for all three varieties compared to sort and control; however, few compounds differed significantly Brenneman, C.A.; Heymann, H.; between the sort and control treatments.

The present study included the economically important ( 5 ) species belonging to ( 5 ) genera of ( 4 ) families. These are ( 5 ) species are cultivated plants in this study. Edible plant parts are mature seeds, young pods, fruits and grains. Plant parts are eaten raw, cooked, salad and boiled. The outstanding features of source plants, parts used and traditional preparations, and uses of a traditional food are also presented with photographs. Keywords: Ethnobotany, Northern Chin State, Myanmar. INTRODUCTION Human being survives by using the material from his natural environment since human being is evolved on the earth. The plant plays one of the supporting roles on the survival of man from that time to present day. Ever since his appearance on the earth, man used plants as food, medicines, fibres, clothes and shelter, etc. For their basic needs, man obtained from wild plants from flora in his early life, before civilization is appeared. Then man domesticated wild plants to produce the food called agriculture. It has been estimated that about 3,000 species of plants have been used as food by human being throughout history and that about 200 species have been domesticated as food crops. Today plants are not only cultivated for food, but also for other man‟s requirements, such as fibres, latexe and resins, dyes, tannin and drugs, etc.

During vinification, the temperature, presence of grape seeds and peel, and use of enzymes, can influence the extraction of polyphenols. However, little information is available on the effects of yeast strains used in the polyphenolic composition of wine. With this aim, two selected Saccharomyces cerevisiae strains, ITEM 14093 and ITEM 14077 were used to produce wine from two Italian grape cultivars, Primitivo and Negroamaro. At the end of the alcoholic fermentation, the content of total polyphenols and of particular classes of polyphenols (stilbenes, phenolic acids, flavonols, and flavanols) and the antioxidant activity were evaluated and compared in the obtained wines. We also examined the effects of red wine extracts in a culture model of vascular inflammation. The results obtained comparing wine extracts obtained by utilizing commercial or autochthonous yeast showed that wines obtained with selected yeast significantly inhibited vascular inflammation. The results are positively directed towards the healthy properties of wine drinking.

This study analyses the influence of pre-fermentation methods; maceration and press fractioning, on the total phenolic content of juice from four apple varieties; ‘Red Delicious’, ‘Pink Lady’, ‘Sturmer’, and ‘Bulmer’s Norman’. The must was macerated for 0 or 2 h and juice was collected at free run or under 200 kpa. Base juice characteristics and total phenolic content was analysed using the Folin–Ciocalteu method and spectrophotometric absorbance at 280 nm (A280), a method used for the analysis of white wine. Both methods of analysing the total phenolic content were used, measuring the same samples to determine if the methods are comparable. No interaction was found between pre-fermentation technique and the results varied by variety and analytical method. High pressure improved the phenolic extraction for ‘Bulmer’s Norman’ juice compared to free run juice when analysed by A280. Non-macerated juice had higher total phenolic content than macerated juice for ‘Red Delicious’ and ‘Pink Lady’ juice when analysed using the Folin–Ciocalteu method.

Abstract Anthocyanin, are the substances which are biosynthesized in the grape skin, extracted during the maceration and vinification and which contribute in wine color. During the aging of wines these substances are converted in their derivates, contributing in wine quality. For this reasons in nowadays there is a big attention of studies in these components. Wines from two grapes variety, a French variety, Cabernet Sauvignon and the other an autochthonous variety of Albania Kallmet were observed. The role of drying in concentration of anthocyanin in skins berry and if this technique is reflected in wine produced from this dried grape, was studied. The results shown that the quantity of anthocyanins from dried skins varied from 136 mg/100gr fresh product to 468 mg/100gr. The dried skins had the higher quantity, but this result was more significant for Cabernet Sauvignon wine than Kallmet wine.
