Vitamins are a huge family, and dozens of vitamins are known at this stage. According to the scope of its application, it can be divided into medical grade, food grade and feed grade. The differences between them are mainly in the following aspects:
I. differences in qualifications.
Food grade must have certificates such as Kosher, Halal, ISO, HACCP, etc.
The medical grade should have GMP.
The Fami-qs certificate is required for the feed level.
II. Differences in quality control standards.
In general, the feed grade will have more impurities and microorganisms than the food grade. Medical grade vitamins must be above USP, for example, vitamin B9 above USP40 is in line with medical grade by default; food grade is FCC or USP36 or above, and feed grade vitamins are generally in line with any CVP/USP/EP/BP test and are considered to be in line with feed grade requirements; different levels of vitamin testing items are also different.
III. the difference of the production line.
Food grade and feed grade are from the same production line. The pharmaceutical grade is produced in the GMP workshop.
IV. Differences in raw materials and technological processes.
The quality standards of starting materials for some vitamins are different (for example, different levels of vitamin E use different contents of VE oil), and there are also slight differences in production process control.
With regard to the differences between medical grade, food grade and feed grade, the specific vitamin products should be analyzed in general. Some are very different, while others are basically no different.
