Contrary to the Essential Oils that only contain the volatile components, Oleoresins are extractives of spices also containing the non-volatile components, resins, waxes, gums, fats, and fatty oils giving them a full flavor with deep herbal, spicy, earthy, and pungent notes.
They also contain active principals, e.g., Piperine in Oleoresin Black Pepper or Capsaicin in Oleoresin Capsicum with there characteristic heat. Curcumin in Oleoresin Turmeric or Carotenoids in Oleoresin Paprika giving them their characteristic color or Carnosic Acid, the active Antioxidant in Oleoresin Rosemary.
The concentration of Oleoresin and Volatile oil content can be adjusted to get the right balance to meet your required flavor profile or specification. Hilltech can also custom blend a mixture of oleoresins with essential oils, other natural extracts or aroma chemicals, to your specific needs or create a unique flavor for your products. We can also adjust the product as needed using a fixed oil e.g., soya, canola, etc… or render the formulation oil or water soluble.
