In general, about 300 g kg(-1) of the weight of papaya fruits appears as waste materials during processing, including a considerable amount of papaya seeds. To make a more efficient use of papaya, it is worth investigating the utilization of the seeds. The aim of this study was to comprehensively assess the lipid characteristics of papaya seed oil obtained by expelling processes.
Papaya seed oil was found to have several unique characteristics, including its high oleic content, the relative ratio of saturated/monounsaturated/polyunsaturated fatty acids of 29/68/3, the polyunsaturated fatty acids merely accounting for 3.34% and its triacylglycerol composition being very similar to that of olive oil. Also, this oil was rich in chemopreventive benzyl isothiocyanate, the level ranging from 4.0 to 23.3 g kg(-1) dependent on the various processing methods for the pretreatment of papaya seeds.
On the basis of our results, papaya seed oil can be considered as a high-oleic oil with a chemoprotective effect, and may be viewed as a healthy alternative in the functional food industry.
一般来说，在加工过程中，约有 300 克/公斤的番木瓜果实重量会变成废物，其中包括相当数量的番木瓜种子。为了更有效地利用番木瓜，值得研究种子的利用。本研究的目的是全面评估压榨工艺获得的番木瓜籽油的脂质特性。
番木瓜籽油具有几个独特的特点，包括高油酸含量、饱和/单不饱和/多不饱和脂肪酸的相对比例为 29/68/3、多不饱和脂肪酸仅占 3.34%，其三酰基甘油组成与橄榄油非常相似。此外，这种油富含具有化学预防作用的苄基异硫氰酸酯，其含量范围为 4.0 至 23.3 克/公斤，具体取决于番木瓜种子预处理的不同加工方法。
根据我们的结果，番木瓜籽油可以被认为是一种具有化学保护作用的高油酸油，并且可以在功能性食品行业中被视为一种健康的替代品。
