“…Throughout the year, the pH value and mineral content remain at the same rates, while the protein content may change [2,10] . Actually, seasons, storage at different temperatures, geographical location, botanical origin, bee race and species, production method, the feed source of the bee, the metabolic and physiological features of the bees, and the age of the larva also affect the physicochemical properties of RJ [2,24,25,28] …”

This study analysed some physicochemical and quality parameters of 176 royal jelly (RJ) samples from different regions of Türkiye, collected over different years and seasons. According to the obtained results, the moisture percentage varied between 47.36% and 69.58%, with no statistically significant differences seen across various seasons and areas (p>0.05). The average value of 10‐hydroxy‐2‐decenoic acid (10‐HDA), which varies according to factors such as season, region, and year, was determined to be 2.32%. It was also seen that this value was close to the international standard. The values of total acidity ranged from 28–58 mL 1N NaOH/100 g. Furthermore, statistical significance (p<0.001) was observed for the year‐region interaction in relation to 10‐HDA and total acidity. The pH measurement results for all samples confirmed the acidic nature of the samples and resulted in a range between 3.45 and 3.80. And the pH variability was also found to be statistically significant for years (p=0.002) and regions (p=0.011). Finally, the correlation analysis between moisture (%), 10‐HDA (%), total acidity, and pH revealed no statistically significant or strong differences. This comprehensive study, supported by statistical analyses, is thought to be a useful reference for future research on RJ.
