成熟度与储存条件对中蜂枇杷蜜理化指标的影响OA

In order to clarify the physicochemical indicators of Eriobotrya japonica honey from Apis cerana under different maturity and storage conditions,and to provide a basis for the harvesting and scientific storage of high-quality Eriobotrya japonica honey,this study comprehensively analyzed the physicochemical indicators of Eriobotrya japonica honey from Apis cerana under four storage conditions(light exposure at room temperature,light avoidance at room temperature,refrigeration,freezing),different maturity levels(unsealed honey and post-ripened honey),and different storage time.The results showed that with the increase of maturity,the moisture content and acidity significantly(p＜0.05)decreased,and the post-ripening treatment significantly increased the glucose and fructose content.Under different storage conditions,amylase activity generally declined,and glucose and fructose content increased.Compared with storage at low-temperature,storage at room temperature led to greater variations in physicochemical indicators.Post-ripened honey exhibited a smaller range of variation in principal component space compared with unsealed honey,suggesting that post-ripening treatment may enhance honey stability.With prolonged storage,fully-sealed honey showed a significant increase in moisture content,acidity,5-hydroxymethylfurfural content,glucose and fructose content,a significant decrease in amylase activity and sucrose content.In summary,to maintain the quality and nutritional value of honey,it is recommended to harvest mature honey and store it at low-temperature(such as refrigeration or freezing),while avoiding prolonged storage at room temperature.
