Recently, hypoglycin A (HG-A), a natural toxin, was detected in canned ackee fruit. To determine the source of contamination, the HG-A content in the ackee fruit components (aril, seeds, and husks) at various stages of ripeness was determined by a method using an amino acid analyzer. HG-A concentrations in the unripe ackee fruit components were 939, 711, and 41.6 mg/100 g of seed, aril, and husk components, respectively. Analysis of the ripe fruit components showed that HG-A in the seed decreased to 269 mg/100 g and remained unchanged in the husk while the concentrations in the edible ripe aril decreased below the detection limit of 1.2 mg/100 g.
最近,在罐装西非荔枝果中检测到一种天然毒素——降血糖素A(HG-A)。为了确定污染来源,采用氨基酸分析仪法测定了不同成熟阶段西非荔枝果各成分(果肉、种子和果壳)中的HG-A含量。未成熟西非荔枝果各成分中的HG-A浓度分别为种子939毫克/100克、果肉711毫克/100克和果壳41.6毫克/100克。成熟果实成分分析表明,种子中的HG-A降至269毫克/100克,果壳中的HG-A保持不变,而可食用成熟果肉中的浓度降至1.2毫克/100克的检测限以下。
