Storage stability Shelf life of the product was studied in products stored at either 25°C/60% RH (18 months) or 40°C/75% RH (6 months). Under both conditions losses of less than 10% of carvone and limonene were observed. The product was also added to a vitamin/mineral premixture and stored at the same temperatures and RH as above but for six months at both conditions. The content of carvone was reduced by 25% and limonene by 39% at 25°C. Losses were higher at 40°C.
Mash or pelleted feed supplemented with the product was stored for four months at the same temperatures and RHs as mentioned above. After four months the loss of carvone and limonene was less than 10%.
Heat stability No data
