sample was dissolved for extraction of primary and secondary extract. Extraction ﬂuid was prepared by taking 5.7 mL of glacial acetic acid and 64.3 mL of 1.0 N of sodium hydroxide in 500 mL of reagent grade water and diluted to a volume of 1 L with reagent grade water. The pH of extraction ﬂuid was checked and found to be 4.93.
Pickling is the process of preserving or expanding the lifespan of food by either anaerobic fermentation in brine or immersion in vinegar. The resulting food is called a pickle, or, to prevent ambiguity, prefaced with pickled. The pickling procedure will typically affect the food's texture and flavor.

A review of the different acid recovery methods; ionic exchange, diffusion dialysis and extraction was made. The study showed that ionic exchange is a robust method with relatively low cost and therefore it has been largely implemented both in Swedish and Chinese industry. The outflow however still requires neutralisation.
