Farm-to-table operations produce, transport, and deliver produce to consumers in very different ways than conventional, corporate-scale agriculture operations. As a result, the time it takes to get a freshly picked fruit to the consumer is relatively short and the expectations of the consumer for freshness and quality are high. Since many of these operations involve small farms and small businesses, resources to deploy sensors and instruments for monitoring quality are scarce compared to larger operations. Within stringent power, cost, and size constraints, this article analyzes chemical sensor technologies suitable for monitoring fruit quality from the point of harvest to consumption in farm-to-table operations. Approaches to measuring sweetness (sugar content), acidity (pH), and ethylene gas are emphasized. Not surprisingly, many instruments developed for laboratory use or larger-scale operations are not suitable for farm-to-table operations. However, there are many opportunities still available to adapt pH, sugar, and ethylene sensing to the unique needs of localized farm-to-table operations that can help these operations survive and expand well into the future.

半透明传感器，用于从农场到餐桌的水果质量监测

从农场到餐桌的操作与传统的公司规模农业操作相比，以非常不同的方式生产，运输和交付产品给消费者。结果，将新鲜采摘的水果带给消费者所花费的时间相对较短，并且消费者对新鲜度和品质的期望很高。由于许多此类操作涉及小型农场和小型企业，因此与大型操作相比，用于部署传感器和仪器以监控质量的资源很少。在严格的功率，成本和尺寸限制的前提下，本文分析了适用于监控水果质量的化学传感器技术，该技术从收获点到从农场到餐桌的食用都经过监控。强调了测量甜度（糖含量），酸度（pH）和乙烯气体的方法。不出所料，为实验室使用或大规模操作而开发的许多仪器均不适用于从农场到餐桌的操作。但是，仍有许多机会可以使pH值，糖和乙烯传感适应当地农场到餐桌操作的独特需求，这可以帮助这些操作生存下来并很好地扩展到未来。
