คำถาม
What is the recommended usage rate for Rosemary Extract (Carnosic Acid 20%, Powder) when incorporating it into rice crackers? This extract is intended to function as a natural antioxidant to prevent lipid oxidation and extend the product's shelf life.
คำตอบ
Rosemary Extract (Carnosic Acid 20%, Powder) is primarily used as a natural antioxidant in fatty food products like rice crackers to prevent lipid oxidation (rancidity) and extend shelf life.
The recommended usage rate for this type of highly concentrated extract (20% Carnosic Acid) in the final product generally falls within the range of 0.02% to 0.1% (200 ppm to 1000 ppm) of the total product weight.
Key Considerations:
- Fat Content: The optimal dosage often correlates with the fat content of the rice crackers. Higher fat content may require a concentration closer to the upper limit.
- Testing: It is crucial to conduct stability tests (such as AOM or Rancimat) on your specific formulation to determine the exact concentration that provides the desired shelf-life extension without affecting the taste or color of the final product.
