摘要

蔓越莓产品因其抗氧化剂含量高而被视为健康食品,但为增加其适口性而添加糖分的做法却阻碍了人们的消费。基因编辑等植物育种技术,特别是成簇的有规则间距回文重复序列(CRISPR),为开发具有所需性状(如降低酸度和增加甜度)的蔓越莓提供了一种可行的替代方法。我们估算了在不同的健康相关信息处理下,消费者对两种蔓越莓产品的含糖量、CRISPR 和蔓越莓风味强度的支付意愿。受访者表示,对常规含糖量的偏好与对减糖产品的偏好、对 CRISPR 的偏好与对传统育种的偏好、对蔓越莓风味的偏淡/平淡的偏好与对蔓越莓风味的偏浓/浓郁的偏好都有折扣。对不同属性水平产品的补偿估值分析表明,相对于普通含糖量、传统育种和弱/平淡风味的蔓越莓产品,消费者愿意为含糖量降低、CRISPR育种和蔓越莓风味浓郁/浓郁的蔓越莓产品支付溢价。强调蔓越莓健康益处和建议限制糖分摄入的信息处理提高了消费者对普通含糖量产品的折扣,超过了对CRISPR产品的折扣。这项研究强调了育种技术获得公众认可的条件的重要性。这些信息将使寻求使用 CRISPR 开发改良蔓越莓栽培品种的科学界和产业界受益。

Would consumers accept CRISPR fruit crops if the benefit has health implications? An application to cranberry products
Cranberry products are perceived as healthy due to their high antioxidant content yet adding sugars to increase their palatability deters consumption. Plant breeding technologies such as gene editing, specifically the clustered regularly interspaced palindromic repeats (CRISPR), offer a plausible alternative to develop cranberries with desired traits (e.g., lower acidity and increased sweetness). We estimated consumers’ willingness to pay for sugar content, CRISPR, and cranberry flavor intensity for two cranberry products under different health-related information treatments. Respondents stated a discount for regular sugar content favoring reduced sugar products, for CRISPR compared to conventional breeding, and for weak/bland compared to full/intense cranberry flavor. Compensated valuation analysis of products with different attribute levels indicates that consumers were willing to pay a premium for cranberry products with reduced sugar content, CRISPR-bred, and full/intense cranberry flavor relative to products with regular sugar content, conventionally bred, and weak/bland flavor. Information treatments highlighting cranberries’ health benefits and recommendations to limit sugar intake increased consumers’ discounts for regular sugar content, surpassing the discount for CRISPR. This research underscores the importance of the conditions under which breeding technologies might gain public acceptance. This information will benefit the scientific community and industry seeking to use CRISPR to develop improved cranberry cultivars.

期刊介绍: The purpose of the Review is to foster and disseminate professional thought and literature relating to the economics of agriculture, natural resources, and community development. It is published twice a year in April and October. In addition to normal refereed articles, it also publishes invited papers presented at the annual meetings of the NAREA as well as abstracts of selected papers presented at those meetings. The Review was formerly known as the Northeastern Journal of Agricultural and Resource Economics
