Cornell University researchers successfully demonstrated that apples as meat additives can comprise up to 20 percent of meatballs without affecting taste, according to tests with over 100 participants.
Researchers at Cornell University have demonstrated that using apples as meat additives is more effective than expected. More than 100 taste testers couldn’t tell the difference between pure beef meatballs and versions containing up to 20 percent freeze-dried apple waste. Honestly, that’s impressive.
The food scientists behind this innovation published their findings in the Journal of Food Science and Nutrition. Their work addresses a significant problem in America’s food production system that most of us never think about.
The United States produced around 10 billion pounds of apples during the 2023-24 growing season, according to the United States Department of Agriculture. About 35 percent of that fruit gets processed into juice, cider, jam, and vinegar. Even with efficient extraction methods, manufacturers still face 25 to 30 percent of each apple becoming waste in the form of leftover skin, core, pulp, and seeds.
The industry currently freeze-dries these scraps and mills them into powder called pomace. This material becomes animal feed or compost, but substantial amounts still end up in landfills where they release methane, a potent greenhouse gas. Transportation of pomace also generates carbon emissions, which doesn’t help anyone.
Food scientist Peter Gracey partnered with Cornell researcher Elad Tako to explore new applications for apple waste. While previous studies had examined the use of apples as meat additives, critical questions remained unanswered, particularly whether consumers would actually accept the taste. That’s the real test.
The research team purchased bulk orders of Empire, Cortland, and Red Delicious apples. They pressed the fruit using a commercial juicer, then freeze-dried the remains for 48 hours before milling them into a consistent powder. After rehydration, they blended the pomace into 80 percent lean ground beef at inclusion rates of 10 and 20 percent.
Over 100 participants sampled the meatballs while researchers analyzed texture, composition, colour, and cooking yields. The 20 percent pomace version reduced the total meatball yield and slightly altered internal colouration. However, the sensory panel reported no significant differences in taste or eating experience. People ate them without complaints.
The concept of using apples as meat additives offers environmental benefits that extend beyond waste reduction. Every pound of apple pomace that goes into food instead of landfills means less methane released into the atmosphere and fewer transportation emissions from hauling waste. Living in Montreal, where we take composting seriously, I appreciate solutions that actually close these loops.

The nutritional profile of these hybrid meatballs also improves. Adding pomace to ground beef increases fiber content, which most of us don’t get enough of anyway. The apples as meat additives approach also boosts micronutrients, polyphenols, and pectin levels. It’s a genuine upgrade.
Tako described the innovation as a win-win-win situation, and he’s right. Meat companies can develop more natural products with enhanced nutritional profiles. Consumers who prioritize protein and nutrient intake get better options. Apple producers and cider makers gain a new revenue stream, rather than facing disposal costs.
The practical applications could transform food production. If restaurants, cafeterias, and meal kit companies adopted even 10 percent pomace in their ground beef products, millions of pounds of apple waste would be diverted from landfills annually. The cumulative environmental impact would be substantial, and we need such a change.
The freeze-drying and milling process is essential for making apples viable as meat additives. It transforms perishable scraps into stable powder that can be stored and used as needed. This opens possibilities for food manufacturers seeking to reduce waste while maintaining product quality.
The research challenges conventional assumptions about food categories. With proper processing, the boundaries between meat and fruit become more flexible than we thought. We might start seeing these ingredients on product labels sooner than expected.
The timing matters as climate change demands rethinking every aspect of food production and consumption. Solutions using apples as meat additives demonstrate practical approaches to reducing the billions of pounds of food waste generated annually. We can’t keep throwing away this much food and expecting different results.
