    • It is perfectly alright to use garlic paste when it turns green. The color change happens due to the change in temperature of the place where it is stored.
    • pH also determines that the solution is acidic or alkaline. So the substances that change the color like vinegar, and lemon, show the acidic pH and change the color of the paste to green.
    • Chopped or minced garlic is more liable to change the color to green because it is in paste form, so the enzymes are directly exposed to the normal temperature.
    • Garlic paste that is cooked completely or partially at a low temperature is liable to change color because the chemical substances and the enzymes are left exposed in the process. So they react to each other and change the color to green.
    • Garlic age also matters in the color change because the older garlic enzymes react quickly to sulfur compounds that gradually lead to turning the green color.

    It is good to use but I prefer not to use it again and again, always keep it in small packs in the refrigerator and take it out when you need it for cooking.
