Fight to curb food waste increasingly turns to science


              In this photo taken Monday, Oct. 24, 2022, in Chicago, Patrick Flynn, a co-founder of Hazel Technologies, holds a sachet designed to slow the ripening of process of various fruits. The ingredients of the packet use scientific concepts to inhibit the naturally occurring hormone ethylene, which causes produce to ripen. The product is used for apples, table grapes, peaches, avocados and other items. (AP Photo/Martha Irvine)

              Apples speed along as they’re sorted for size and quality at the BelleHarvest packing and storage facility, Tuesday, Oct. 4, 2022, in Belding, Mich. This process happens repeatedly throughout the year as apples are taken out of special storage rooms that help them stay fresher. They are then sent to grocery stores.

Pauls is a fifth-generation apple grower and attended Michigan State University to study agriculture. She says science-based technology for storing apples has improved markedly, even in the past few years. That means more of her family’s apples make it to consumers throughout the year.

Hazel is one of several companies that's using science to try to help fruit growers keep their product fresher, especially as consumers demand fresh fruit all year round. The goal is also to prevent food waste and ultimately the release of methane, a greenhouse gas that rotting fruit emits and that impacts the climate. (AP Photo/Martha Irvine)
