Reggio Emilia designates the different ages of their balsamic vinegar (aceto balsamico tradizionale di Reggio Emilia) by label colour. A red label means the ...
Pay close attention to the labels, seals, bottle shapes and even the wax-and-cork closures.
The acetic acid in vinegar is what provides most of the health benefits, and all types of vinegar used for cooking contain about the same amount of acetic acid, Johnston says.
If the product is kept there for 3 years or more it is labeled "invecchiato" ('aged'). The balsamic vinegar of Modena gained the PGI label on 3 July 2009. [1] The requirements for the much more expensive PDO Traditional Balsamic Vinegar are different and more restrictive; it must contain only grape must and be aged for at least 12 years.
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Alkaline cleaning agents contain strong bases like sodium hydroxide or potassium hydroxide. Bleach (pH 12) and ammonia (pH 11) are common alkaline cleaning agents. Often, dispersants, to prevent redeposition of dissolved dirt, and chelants, to attack rust, are added to the alkaline agent.
Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats. Drain cleaners can also contain aluminum, which reacts with sodium hydroxide to produce bubbles of hydrogen gas that help to break up the clog. [11]
