Open-source benchmarking of dairy and dairy-free products
This paper presents the first open-source sensory benchmark from the NECTAR 2026 study, which evaluates 112 commercial dairy-free products against dairy counterparts across ten categories to demonstrate that sensory parity is achievable in beverages while identifying specific flavor and texture deficits in solid dairy alternatives that offer key opportunities for future innovation.

Imagine you are a chef trying to build a perfect replica of a famous castle using only LEGO bricks. You have the blueprints (the taste and texture of real dairy), but your building blocks are made of plants, nuts, or seeds. This is the world of food science, specifically the art of "sensory evaluation." In this field, scientists don't just taste food to see if it's yummy; they act like detectives, breaking down exactly why something tastes or feels the way it does. They look at specific clues like "mouthfeel" (how heavy or smooth it feels on your tongue), "flavor notes" (is it nutty, bitter, or creamy?), and "similarity" (does it fool your brain into thinking it's the real thing?). Why does anyone care? Because millions of people want to enjoy the magic of cheese, milk, and butter without using animal products, but the "LEGO castle" often looks a little wobbly compared to the real stone one. The big question is: have we finally built a plant-based replica that is strong enough to stand next to the original?
This paper is like a massive, blind taste-test tournament where scientists put dairy-free products and their dairy "ancestors" in a ring to see who wins. The researchers gathered a huge crowd of 2,183 regular people to act as the judges. They didn't just ask, "Do you like this?" They set up a rigorous game with 112 different products across ten categories, ranging from the stretchy pull of mozzarella to the frothy foam of a latte. In total, they collected over 79,000 survey answers, creating a giant map of how people feel about these foods.
The results are a bit of a mixed bag, like a sports team that dominates in some games but struggles in others. For the liquid categories—specifically barista milk, creamer, and fluid milk—the plant-based versions are so close to the real deal that they pass a strict "similarity test." It's as if the LEGO castle is so well-built that you can't tell the difference from a few steps away. However, the paper finds that other categories are still playing catch-up. The biggest gap was found in mozzarella, which fell short by 1.46 points on a 7-point scale, followed by Greek-style yogurt and butter. These differences were big enough that the scientists are confident they aren't just random luck; the plant-based versions genuinely taste different in a way that matters to the judges.
The study also acted like a magnifying glass to find out why the losing products lost. Through a process called "penalty analysis," the researchers discovered that the biggest killers of enjoyment were specific off-putting flavors. If a product tasted "artificial," "chemical," "stale like cardboard," or left a "bitter aftertaste," people's liking scores dropped hard. It turns out that while we have mastered the smooth, creamy liquids, the complex, stretchy, and tangy textures of cheese and butter still have some rough edges. Ultimately, this research doesn't declare a total victory for plant-based foods, but it does draw a clear line in the sand: we know exactly where we have succeeded in making a perfect copy, and we know exactly which flavors and textures need the most work to get there.
