Citric acid sold in a dry powdered form is commonly sold in markets and groceries as "sour salt", due to its physical resemblance to table salt. It has use in culinary applications, as an alternative to vinegar or lemon juice, where a pure acid is needed. Citric acid can be used in food coloring to balance the pH level of a normally basic dye.
Ascorbic acid: Found in oranges and green peppers and gives a crisp, slightly sour taste, better known as vitamin C. C 6 H 8 O 6: 4.10 Citric acid: Found in citrus fruits and gives them their sour taste. C 6 H 8 O 7: 3.13 Fumaric acid: Found in bolete mushrooms, Icelandic moss and lichen. Not found in fruits, used as a substitute for citric and ...
Speciation diagram for a 10-millimolar solution of citric acid. The violet curve corresponds to the trisodium citrate. As a conjugate base of a weak acid, citrate can perform as a buffering agent or acidity regulator, resisting changes in pH. It is used to control acidity in some substances, such as gelatin desserts. It can be found in the milk ...
Citric acid – food acid; Citric acid esters of mono- and diglycerides of fatty acids – emulsifier; Citrus red 2 – color (red) Cloves – Cochineal – color (red) Coconut oil – a cooking oil, high in saturated fat – particularly used in baking and cosmetics. Sage (Salvia officinalis) – Copper complexes of chlorophylls – color ...
Lime juice contains slightly less citric acid than lemon juice (about 47 g/L), nearly twice the citric acid of grapefruit juice, and about five times the amount of citric acid found in orange juice. [14] Lime pulp and peel contain diverse phytochemicals, including polyphenols and terpenes. [15]
The acid involved in citrus fruits (lemons, oranges, grapefruits, etc.) is citric acid. The acidity, which is indicated by the measured pH, varies substantially. Potatoes have phosphoric acid and work well; they are the basis for commercial "potato clock" kits.
The carpels are juicy; they contain a high quantity of citric acid, which with other organic acids including ascorbic acid (vitamin C) give them their characteristic sharp taste. [30] Citrus fruits are diverse in size and shape, as well as in color and flavor, reflecting their biochemistry; [ 31 ] [ 32 ] for instance, grapefruit is made bitter ...
It is also used as an anticoagulant for laboratory testing, in that blood samples are collected into sodium citrate-containing tubes for tests such as the PT (INR), APTT, and fibrinogen levels. Sodium citrate is used in medical contexts as an alkalinizing agent in place of sodium bicarbonate, [2] to neutralize excess acid in the blood and urine ...
