Proteins
From a quantitative viewpoint, proteins (27-41%) represent the most important portion of the dry matter of RJ. The amino acids present in the highest percentages were proline, lysine, glutamic acid, β-alanine, phenylalanine, aspartate and serine (Boselli et al., 2003). The concentration of series D amino acids was below the detection limit of the method (0.1mg/g of RJ) in all samples.

The study aimed to assess how this parameter evolved during storage of the product. No significant changes were observed in the overall concentration of free amino acids in RJ stored at 4°C for 10 months. However, in the same samples stored at room temperature, the proline and lysine content showed an increase in the first three months and after 6-10 months decreased to levels slightly lower than those in the control samples. This suggests that, in favourable temperature conditions, a proteolytic enzymatic activity continues to occur over time.
 
Lipids and 10-Hydroxy-2-decenoic acid (10-HDA)
The analyses we performed showed that the composition remained stable for as long as 2 years, regardless of whether the samples were stored at 4°C or at room temperature. A recent study (Antinelli et al., 2003) showed a 0.4 and 0.6% reduction in 10-hydroxy-2-decenoic acid in two RJ samples stored at room temperature for 12 months.
 
研究說明蜂王乳中的各項重要胺基酸活性在4℃保存長達10個月出乎意料蜂王乳中重要元素游離胺基酸在前3個月不管在4℃或是室溫下還會持續增加,直到6個月後才下降。另外癸烯酸在4℃或是室溫下,在12個月後只減低0.4%~0.6% 呈現出穩定狀態
實際研究結果能提供我們在選擇蜂王乳冷凍或冷藏時思考判斷的參考依據,
依個人食用生鮮蜂王乳習慣需要選擇冷凍或冷藏時請注意:
• 生鮮蜂王乳冷凍請於9個月內食用完畢
• 冷藏請於3個月內食用完畢
如果個人習慣喜歡冷凍口感的蜂王乳建議請於9個月內食用完畢最佳,另外能每天吃蜂王乳的朋友如果選擇冷藏方式(0~5℃)請在3個月內食用完畢,讓生鮮蜂王乳能在活性最佳時期被人體有效吸收利用。
