Samples with oil-soluble rosemary extract showed similar
mean b⁄ values to control samples, and significantly (P < 0.05)
lower than samples with a mixture of synthetic and natural antioxidants.
The mean values of L⁄ and b⁄ increased (P < 0.05) during
storage. The initial a⁄ value (3.74) increased to 4.29 during
50 days of storage, and then it decreased to reach 4.10 on day
90.
