Recently, a social media post in which a user brewed drip coffee using a face mask instead of filter paper sparked heated discussion. In the photo, the mask was hung over the rim of the cup to serve as a filtering tool, and the caption claimed it had a "unique taste." This move quickly drew a flood of criticism and concern. Some questioned whether the mask's water-resistant layer and adhesive layer might release toxic substances, while others joked that this was an attempt to compete with "Lianhua Qingwen coffee." In fact, this practice stemmed from a "clever trick" some netizens came up with to avoid wasting expired masks, but medical experts point out that the non-woven fabric in the inner layer of masks is made of polypropylene (PP), and although the amount of harmful substances released when heated is trace, it is still not recommended for contact with food. Front Street Coffee reminds everyone that coffee filter paper costs about the same as a mask, and choosing standard filter paper is the safe and reliable way to brew coffee. [more…]

The well-known tea beverage brand Yihotang has been exposed by media undercover investigations at multiple stores in Zhengzhou for serious food safety issues: ingredients that should have been discarded after closing were used again the next day, expired materials had their labels swapped to extend their shelf life, moldy strawberries were washed and used as usual, flying insects that fell into toppings were fished out and still used in products, and even prepared drinks in which bugs were found were resealed and continued to be sold.
