What We Do

Perfection You Can Taste
At GraidenTong, we are committed to creating restaurant quality products, that can go from freezer to fork in just minutes. We don’t strive to be good, we aim for perfection. This means setting ourselves the goal of exceeding our customer expectations every step of the way – from concept to plate. Here’s how we do it:

Perfectly selected raw materials

We use the highest quality raw materials as we believe the quality of the raw materials has a large impact on the finished product.

Perfect taste

We create inspirational products, adapted to the tastes of our markets, at our R&D centre in Israel. From lab to food trials, we maintain constant communication with customers through testing panels till they love the final product.

Perfectly healthy products

A wave of healthy eating trends over the past few years, including high protein, omega enriched foods, low carbs, low calories, low sugar and low salt - have brought an influx of new consumers to the delights of healthier foods. In fact, year-round, people are making room on their plates for more fish and other seafood. A fish-rich diet lowers the risk of heart disease and may help with weight control and early brain development.
