酸水解法生产酱油,是我国过去曾经允许使用的一种生产酱油的旧工艺。由于该工艺生产酱油需使用工业酸碱,而工业用酸碱中往往含有砷、铅等金属,因此,酱油常受这些毒物的污染,食用后可发生急、慢性中毒。而且,流行病学调查证实,无机砷可引起表皮内癌和肺、支气管、喉等处的呼吸道癌。过去,因食用酸水解酱油引起中毒的事例常有 Acid hydrolysis production of soy sauce, is used in China in the past has allowed the production of an old soy sauce process.

Moreover, epidemiological investigation confirmed that inorganic arsenic can cause intraepidermal cancer and lung, bronchial, laryngeal and other respiratory cancer. In the past, often caused by eating acid hydrolysis of soy sauce poisoning
