DHC Olive Virgin Oil
ASSURANCE
Quality control for DHC supplements is handled by the DHC Quality Management Office and plants in Japan that have earned Good Manufacturing Practices (GMP) certification. The factory conducts 12 types of testing, quality is confirmed from various perspectives. A few of these 12 tests are described below.
stepO1
Weighing and quantitative testing
Weighing
This test checks capsule measurements and weights. The resulting figures are managed by computer and transmitted to the central system.
Quantitative testing
We confirm that capsules contain the specified volumes of ingredients by dissolving capsule contents in a solvent and measuring them using specialized machinery.
stepO2
Destructive testing
Capsules are placed in pure water and shaken vertically for 20 minutes before checking their state to confirm they will be properly digested after consumption.
stepO3
Microbial testing
Products are checked in a clean environment to confirm they are entirely free from harmful microbes. This is normally done three times: on receipt of raw materials, after visual inspection of capsules, and after portioning products into packages.
stepO4
Package specification inspection
We check to confirm that printed best-by dates and lot numbers found on pouches and the numbers of capsules provided are as specified.
