| 1 | Perfluorooctane sulfonate(PFOS) and related fluorochemicals in chicken egg in China显示文摘The ubiquitous occurrence of perfluorinated compounds(PFCs) in environmental samples has drawn much attention.Recent human exposure studies found relatively high perfluorooctane sulfonate(PFOS) concentrations in blood samples from several cities in China when compared with other countries.The objectives of the present study were:(1) to measure PFC concentrations and compositions in chicken egg samples from local markets in China;and(2) to conduct a preliminary human health risk assessment of egg consumption.Eight pooled egg samples from eight locations were analyzed for 11 PFCs.The results showed that close to 100% of the PFOS in the egg was distributed in egg yolk and PFOS was not detected in egg white(<0.08 ng/g wet weight,w/w).Of the perfluoroalkylsulfonates,only PFOS was detected in all egg samples,while of the perfluoroalkylcarboxylates,perfluoroundecanoic acid(PFUnDA) was detected in all samples,followed by perfluorooctanoate(PFOA)(75% occurrence) and perfluorodecanoic acid(PFDA)(50% occurrence).PFOS concentrations in egg ranged from 45.0 to 86.9 ng/g w/w.The results suggested that current concentrations of PFOS in domestic chicken eggs are unlikely to cause immediate harm to Chinese populations. | WANG Yuan YEUNG Leo Wai Yin YAMASHITA Nobuyoshi TANIYASU Sachi SO Man Ka Margaret B.

| 15 | Effects of flash-boil shucking on biochemical,sensorial and ultrastructural properties of Yesso Scallop(Mizuhopecten yessoensis)adductor muscle during refrigeration显示文摘Scallop adductor muscle has great popularity for raw consumption in Japan,but conventionally shucking live scallops with high vitality by knife requires skill and is time-consuming.Flash-boil shucking is a convenient shucking method in sushi restaurants for live scallops.However,the effects of this treatment on the quality of its main edible part,the adductor muscle,are not clear.This study was conducted to investigate the impact of flash-boil shucking on the quality of raw-edible scallop adductor muscle,focusing on flavor-enhancing components and ultrastructure.Thermal treatment could contribute to the formation of flavor-enhancing nucleotides in the external layer of the adductor muscle.Adenosine monophosphate content increased with the boiling time,which significantly increased to 1.47±0.42μmol/g in the 30 s-boiled group compared with 0.38±0.13μmol/g in the control group(p<0.05).The rapid adenosine monophosphate accumulation after boiling resulted in a faster accumulation of inosine and hypoxanthine during subsequent refrigeration,which could bring bitterness to aquatic products.Flash-boil shucking had no discernible effect on the proportion of free amino acids relevant to the flavor of scallop adductor muscle,despite the possibility of a reduction in total free amino acids.The external layer of the scallop adductor muscle could be hardened after flash-boil shucking.At the ultrastructural level,muscle fibers tend to aggregate transversely and contract longitudinally depending on the heating time.Flash-boil shucking is ideal for consuming the raw-edible scallop adductor muscle promptly.Flash-boil shucking treatment is recommended for households,restaurants,and small factories for treating scallops with high vitality. | Yabin Niu Shiliang Dong Nobuyoshi Wada Huamao Wei Tetsuro Yamashita Koichi Takaki Chunhong Yuan | 2023 | Food Quality and Safety2023，7，3： | 0 |
