Abstract:

To study the effect of storage temperature and storage time on the quality of royal jelly, the contents of total protein, 10-HDA, free sugar, free amino acid and free fatty acid of royal jelly were determined on linden tree royal jelly, cole royal jelly and robinia royal jelly. The scavenging ability of hydroxyl radical and DPPH radical were also analyzed. The results showed that there were significant differences in total protein content and 10-HDA content among different nectar sources. Short-term storage did not cause significant changes in total protein content and 10-HDA content, but the content of glucose and fructose of cole royal jelly increased and the content of sucrose decreased significantly (P<0.05). The contents of amino acids and free fatty acids were similar. After short-term storage, the contents of glutamic acid, palmitic acid, oleic acid, linoleic acid and α-linolenic acid in cole royal jelly were significantly increased, while alanine, oleic acid in linden tree royal jelly and leucine and histidine in robinia royal jelly were decreased. The scavenging abilities of hydroxyl radical and DPPH free radical in three kinds of royal jelly from different sources were significantly decreased after storage (P<0.05). This study can provide theoretical reference for the quality evaluation of royal jelly in chemical composition and antioxidant activity.

Key words: royal jelly, storage, temperature, quality, antioxidant activity
