Cranberry juice is an acidic drink with a pH of about 2.6. [9] Some cranberry juice products contain large amounts of sugar used in manufacturing to make the drink more palatable, but their consumption may increase the risk of hyperglycemia and reduced control of blood glucose in people with diabetes or glucose intolerance.
In chemistry, titratable acid generally refers to any acid that can lose one or more protons in an acid–base reaction. The term is used slightly differently in other fields. For example, in renal physiology, titratable acid is a term to describe acids such as phosphoric acid , sulfuric acid which are involved in renal physiology .
While V. riparia shares many important characteristics with its cousin, Vitis vinifera, the small size of the berry (making it prone to predation by birds), the high acidity of its fruit (often up to 5% titratable acidity), the intense pigment of its juice, and the presence of herbaceous aromas in wine produced from it have made it unusable on ...
Steps taken before fermentation might include fruit or juice blending, titratable acidity and pH measurements and sometimes adjustments, and sulfur dioxide and yeast additions. [42] Fermentation is carried out at a temperature of 4–16 °C (39–61 °F).
The measure of the amount of acidity in wine is known as the “titratable acidity” or “total acidity”, which refers to the test that yields the total of all acids present, while strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. Generally, the lower the pH, the higher the acidity in the wine.
Other measurements taken of apple varieties towards use in cider classification include pH, polyphenol composition, yeast assimilable nitrogen (YAN), [8] and soluble solid concentration (ºBrix). [18] The sharpness of an apple is affected by pH and titratable acidity. Most cultivars must reach pH levels of around 3.3 to 3.8 to aid in the ...

Apple juice is a fruit juice made by the maceration and pressing of an apple. The resulting expelled juice may be further treated by enzymatic and centrifugal clarification to remove the starch and pectin , which holds fine particulate in suspension, and then pasteurized for packaging in glass, metal, or aseptic processing system containers, or ...
