Study on the Stability of Insect Wax during Storage Period

Abstract:

For the wide application of insect wax, it was studied on its thermal properties under different conditions in which the wax was stored at cold, dark, indoor and sunshine environment. Differential scanning calorimetry (DSC) was selected to achieve thermal parameters and reveal the influence of temperature on the stability of the wax. The result showed that within 20 months of natural storage, it was significant influence on the melting enthalpy of Hunan insect wax, the melting point of Sichuan insect wax and the melting peak of Sichuan insect wax with the Sig values were 0.013, 0.009 and 0.000. And the quality of wax was characterized by IR, XRD and physical-chemical indexes. The results showed that within 20 months, it was slightly changed in the crystallinity and chemical constituents. Therefore, the wax with good stability can be used for medicine, food, functional materials and other industrial purposes safely.
