Upcycling of flaxseed meal from waste into functional ingredients toward zero-waste biorefinery concept: a comprehensive review for maximizing food and nutritional applications

What if the leftover flaxseed meal from your kitchen could become the next superfood ingredient? This review shows how waste can be transformed into valuable functional foods—turning trash into treasure.

Flaxseed meal, a byproduct of oil extraction, is often discarded despite being packed with nutrients. This comprehensive review explores how this waste can be upcycled into functional ingredients, supporting a zero-waste biorefinery concept. The goal is simple: maximize food and nutritional applications while reducing environmental impact.

Scientists highlight that flaxseed meal contains valuable bioactive compounds, including lignans, dietary fiber, and omega-3 fatty acids. These components offer potential health benefits, such as antioxidant and anti-inflammatory properties. By extracting these compounds, we can create functional ingredients for food products, nutraceuticals, and even animal feed.

The review emphasizes the need for efficient extraction technologies and sustainable processing methods. It also identifies research gaps, such as optimizing extraction yields and understanding bioavailability. The vision is a circular economy where agricultural waste becomes a resource, not a problem.

For scientists, students, and curious readers, this review is a call to rethink waste. Flaxseed meal is no longer just a byproduct—it's an opportunity. With the right innovations, we can turn a problem into a solution, one seed at a time.
