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 ...
Cottonseed oil – a major food oil, often used in industrial food processing. Cress – Crocetin – color; Crocin – color; Crosslinked Sodium carboxymethylcellulose – emulsifier; Cryptoxanthin – color; Cumin – Cumin oil/Black seed oil – used as a flavor, particularly in meat products. Also used in veterinary medicine. Cupric sulfate ...
Cheese proteins that have denatured during processing are reestablished using melting salts. [7] Sodium citrate and sodium phosphate are the main emulsifiers used in Easy Cheese to sequester calcium in cheddar cheese. This occurrence hydrates and solubilizes the casein, causing it to swell with water. [8]
Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a
Citric acid is used as an odorless alternative to white vinegar for fabric dyeing with acid dyes. Sodium citrate is a component of Benedict's reagent, used for both qualitative and quantitative identification of reducing sugars. [39] Citric acid can be used as an alternative to nitric acid in passivation of stainless steel. [40]
Acid Description Formulation pKa (when applicable, pKa1) Acetic acid: Gives vinegar its sour taste and distinctive smell.: C 2 H 4 O 2: 4.756 Ascorbic acid: Found in oranges and green peppers and gives a crisp, slightly sour taste, better known as vitamin C.
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
It is a defined, selective and differential medium that tests for an organism's ability to use citrate as a sole carbon source and ammonium ions as the sole nitrogen source. After citrate enters a cell through citrate permeases, citrate lyase cleaves it into acetate and oxaloacetate, which is further broken down into carbon dioxide and pyruvate ...
