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).
Olives are often soaked in sodium hydroxide for softening; pretzels and German lye rolls are glazed with a sodium hydroxide solution before baking to make them crisp. Owing to the difficulty in obtaining food grade sodium hydroxide in small quantities for home use, sodium carbonate is often used in place of sodium hydroxide. [46]
Lye (sodium hydroxide (NaOH) or potassium hydroxide (KOH)) is a highly alkaline agent most commonly used for the purpose. However, lye is not the only way to produce the needed result: a baking soda or washing soda solution, which is easier to handle and safer to use, will provide a similar product but will not provide as strong a reaction, so ...

To make hominy, field corn (maize) grain is dried, and then it is treated by soaking and cooking the mature (hard) grain in a dilute solution of lye (potassium hydroxide) (which can be produced from water and wood ash) or slaked lime (calcium hydroxide from limestone). The maize is then washed thoroughly to remove the bitter flavor of the lye ...
The saturated lutefisk is then soaked in an unchanged solution of cold water and lye for an additional two days. The fish swells during this soaking, and its protein content decreases by more than 50 percent, producing a jelly-like consistency. When this treatment is finished, the fish is saturated with lye and inedible, with a pH of 11–12.
The organoleptic quality of the food refers to its sensory properties, that is its look, taste, smell, and texture. Examples of hurdles in a food system are high temperature during processing, low temperature during storage, increasing the acidity, lowering the water activity or redox potential, and the presence of preservatives or ...
Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate and ethanol: C 2 H 5 O 2 CCH 3 + NaOH → C 2 H 5 OH + NaO 2 CCH 3
