Abstract

PURPOSE: To obtain dyer's grapes having a beautiful skin and a high product value, by treating rusty dyer's grapes with a dil. aqueous alkali, and by treating the washed grapes with an aqueous acid to scrape off only the skin readily and rapidly.
CONSTITUTION: Rusty dyer's grapes with discolored fine wrinkles are immersed in a dil. aqueous alkali, e.g. 0.03W5wt% aqueous caustic soda, and heated at 80W 95°C for a given time, and taken out. The surfaces are then scraped off mechanically with a brush or scrub brush, and rinsed with water. The grapes are then immersed in an aqueous acid, e.g. organic acid such as citric acid, or hydrochloric acid, to give the desired product at a pH of 4.2W4.3 with a salt content of about 20%.
