Question
Why does Vitamin C degrade quickly, causing it to turn yellow/brown? What factors contribute to this degradation, such as water purity, mixing temperature, packaging (like amber glass bottles), air exposure, and storage temperature?
Answer
In this context, 'ควรตำ' (khuan tam) is a colloquial Thai phrase used to strongly recommend something. It means 'should buy' or 'highly recommended', indicating that the product is very good and worth purchasing.
