INFUSED WATER ANGGUR MERAH (Vitis Vinifera) MENINGKATKAN pH PLAK DAN pH SALIVA

Amperometric micro pH measurements in oxygenated saliva.

An amperometric micro pH sensor has been developed based on the chemical oxidation of carbon fibre surfaces (diameter of 9 μm and length of ca. 1 mm) to enhance the population of surface quinone groups for the measurement of salivary pH. The pH analysis utilises the electrochemically reversible two-electron, two-proton behaviour of surface quinone groups on the micro-wire electrodes. A Nernstia...

Reducing the Sugar and pH of the Grape (Vitis vinifera L. cvs. ‘Grenache’ and ‘Tempranillo’) Through a Single Shoot Trimming

Many vineyards all over the world can easily produce high potential alcohol levels, but the importance of the sugar content in berries has been changing over the past few years. The objective of this work was to reduce the sugar and pH of the grapes, delay berry ripening by decreasing the ratio between the leaf area and yield, perform an intense trimming treatment after berry set and establish ...

Evolutionary genomics of grape (Vitis vinifera ssp. vinifera) domestication

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated perennial crop, to address three ongoing mysteries about plant domestication. The first is the duration of domestication; archaeological evidence suggests that domestication occurs over millennia, but genetic evidence indicates that it can occur rapidly. We estimated that our wild and cultivated grape sam...

Color and Color Stability of Red Wine from Noble (Vitis rotundifolia Michx.) and Cabernet Sauvignon (Vitis vinifera L.) at Various pH

Muscadine grapes (Vitis rotundifolia) are the most widely planted grapes in the south and southeast United States due to their suitability in these areas. Most of the commercial muscadine grape crop is used to produce wine. Wine made from suitable cultivars of muscadine grapes possesses a very fruity, unique flavor and aroma that appeals to many people in the South. However, muscadine grape pro...
