2. Three major reasons why lilies become sour
1.natural ingredient reaction: Fresh lilies contain about 0.1% colchicine, which will decompose to produce trace amounts of acidic substances when exposed to heat. According to laboratory data, the pH may drop from 6.8 to 6.2 after boiling.
2.Sulfur smoke residue: Some businesses will perform sulfur fumigation to extend the shelf life. When the residual amount of sulfur dioxide exceeds 0.05g/kg, sulfurous acid is generated when it comes into contact with water, which is a common cause of sour taste in industrial processing.
3.Improper storage and deterioration: Lilies stored in a humid environment may breed mold and produce organic acids such as lactic acid. Data shows that when the humidity is >75%, the acidity can increase by 40% within 3 days.
