We have five development laboratories throughout the world — in Shanghai, Jakarta, Milan, New York, and Mexico — which offer tailored and localized support for our customers.

Sustainable, Transparent Farming

Operating sustainably in our farming communities is one of our highest priorities. To this end, we collaborate closely with our farmers in several ways. First, we proactively educate on new developments, including high-yielding, proprietary varieties that can enable maximum efficiency. Secondly, we ensure that raw materials are always sourced through a professionally managed, transparent, and environmentally-friendly supply chain that delivers on our customers’ expectations.

Year by year, we continue to increase our investment in ingredient research and development, enhancing our capabilities and overall product line. Utilizing new raw materials, we are constantly improving older products and introducing innovative solutions to address fast-changing marketplace needs. We have developed numerous bespoke solutions for beverage, dairy, baking, and confectionery applications in the food industry, as well as products for customers in the pharmaceutical and nutritional sectors. The breadth and depth of these development efforts have resulted in one of the industry’s leading patent portfolios.
