Effect of Storage on Various Honey Quality Parameters of Unifloral Sidder Honey from Pakistan

摘要

The sidder or ber honey of Pakistan can be stored for one year without seriously compromising with its quality. Although the values of various quality criteria had altered over a period of one-year; but they remained within the permissible limits. After one year of storage the pH varied between 7.4 and 6.8 for Bannu ber honey, 7.2 and 6.9 for Karak ber honey and 5.6 and 4.9 for Chunian ber honey. Similarly free acidity ranged between 6.5 and 29 meq/kg, 5.5 and 17meq/kg, 16 and 36.5meq/kg, lactone 0-2.7tneq/kg, 17.5meq/kg, 0-2.5meq/kg, total acidity 6.531.7meq/kg, 6.5-24.5meq/kg, 16-39meq/kg, Electrical conductivity between 0.53-0.61mS/cm, 0.51-0.56mS/cm and 0.220.40mS/cm, HMF content between 2-11.2mg/kg, 1.7-10.5mg/kg, 4.6-26.9mg/kg, Proline content between 608.4-341.2mg/kg, 2800-476mg/kg, 621.2-147.3mg/kg, Diastase number between 33-23.4DN, 31-23.8DN, 42-27DN and Invertase number between 72.2-50.1, 68.7-52.9 and 90.27-44.7 for 13annu, Karak and Chunian ber honey, respectively.
