Scientific Quality Control for Oil Safety

Cheng-Chi applies scientific methods to manage oil quality internally. We use two official inspection tools recognized by national hygiene regulations: acid value test strips and a total polar compounds analyzer. While traditional cooking methods for shallot oil may not require such monitoring, we believe that every additional precaution means greater peace of mind.

Multiple tests are conducted daily, and all results are carefully documented to ensure that every batch of oil meets national food safety standards. We take this responsibility seriously, so that our customers can enjoy delicious flavors with confidence and health assurance.
