液相色谱-原子荧光光谱法测定紫菜中无机砷的分析

本文针对紫菜中无机砷采用液相色谱-原子荧光光谱法测定方法的分析。紫菜中的砷主要以一甲基砷酸、二甲基砷酸及砷糖、甜菜碱、砷胆碱等多种形态存在,根据原先的分光光度法与原子荧光法无法得到准确的无机砷数值,通过采用价态分析法才能得出较为准确的结果。     

Who Eats Seaweed? An Australian Perspective

Abstract

Current seaweed consumption and attitudes and preferences toward seaweed food products in a Western society are investigated to inform the seaweed industry regarding product development and marketing strategies. A national survey of 521 Australian consumers was conducted. About 75% of respondents had eaten seaweed; however, only 37% had consumed seaweed regularly over the past 12?months. Key drivers include health and nutritional benefits, taste, being natural, safe, and fresh. Critical barriers are lack of knowledge and familiarity, and the perception that seaweed is expensive. Females and younger, health-conscious consumers with higher household incomes and levels of education, who are more adventurous with food (neophilic), and who tend to snack and assign symbolic value to food are more likely to consume seaweed. Recommendations for the emerging seaweed industry in terms of target markets and relevant marketing strategies are presented and areas of further research proposed.
