Stability of Oil-Soluble Vitamin C with Heat
คำถาม
Regarding oil-soluble Vitamin C, specifically Ascorbyl Palmitate (Vitamin C Ester), it requires relatively high heat for dissolution. Does this high heat not cause the vitamin to degrade? How does this compare to another oil-soluble form like Perfect-C™ (Ascorbyl Tetraisopalmitate), which does not require heat?
คำตอบ
Subject: Regarding oil-soluble Vitamin C and heat
Thank you for your question regarding oil-soluble Vitamin C and the use of heat.
Based on the discussion, you are likely referring to Ascorbyl Palmitate (Vitamin C Ester). This form of Vitamin C is a powder and requires heat, typically around 70°C, to dissolve properly in oil.
Regarding your concern about heat causing degradation: While high temperatures can affect some vitamins, the recommended method for dissolving Ascorbyl Palmitate involves using heat for only a short duration. This is necessary for dissolution and is done to minimize potential quality loss.
It's important to distinguish this from Ascorbyl Tetraisopalmitate (Perfect-C™), which is another oil-soluble Vitamin C. Ascorbyl Tetraisopalmitate is already in liquid oil form and does not require heat for dissolution. In fact, it should not be exposed to heat.
So, for Ascorbyl Palmitate, short-term heating is a necessary step for formulation, designed to balance dissolution with stability. For Ascorbyl Tetraisopalmitate, no heat is needed or recommended.
