The corolla is slender and long, with five lobes that are narrow and strip-shaped, measuring 5–8 mm in length. It has five stamens, with the anthers fused into a tubular shape and yellow-white in color. The stigma is oblong and slightly forked at the tip, with a soft texture. It has a faint odor and a slightly bitter taste. 4.1 Technical Requirements 4.1.1 Quality Standards The quality of saffron must meet the requirements specified in Table 1.

Observe under a microscope (5–10x magnification) and remove impurities. If there are impurities that can be sieved, sieve them out using an appropriate sieve. 2. Weigh each type of impurity and calculate their content in the sample (in %). 5.2 Water Content Take 2–5 g of the sample, spread it evenly on a dry and weighed flat-shaped weighing bottle (thickness ≤ 5 mm, loose sample ≤ 10 mm), weigh it accurately (to 0.1 g), open the bottle cap, dry at 100–105°C for 5 hours, close the bottle cap, tran
