Sweet Potatoes

Sweet potatoes are starchy, sweet root-vegetables that have earned the “superfood” status with their variety of health benefits, and they are prized primarily for their high antioxidant levels. Their high fibre content have also been shown to promote healthy digestion. Best of all, they are naturally delicious and come in beautifully coloured varieties such as yellow, orange, and purple. 

Despite the name, sweet potatoes (root-vegetables) are not actually potatoes (tubers). They are also commonly confused with yams. (In Chinese only: 紫薯 vs 紫心番薯)

Colourfully Healthy

Sweet potatoes are prized for their antioxidants, with the colour of the potato flesh determining the source and amount. Orange and yellow sweet potatoes are rich in carotenoids (a good source of vitamin A), where as purple sweet potatoes are rich in anthocyanins.

Anthocyanins are naturally found in purple-hued fruits and berries. According to a study published in Food and Nutrition Research in 2017, anthocyanins may possess anti-diabetic, anti-inflammatory, anti-microbial and anti-obesity effects, as well as help protect against cardiovascular disease and cancer.


In the early days of our company, we were called upon by local bakers in Hong Kong to produce commercially packed Sweet PotatoTaroRed Bean, and Black Sesame fillings that were widely popular in Japan and Taiwan. Our products became a hit and we soon found ourselves serving the R&D departments of multinational food companies. 

Fast forward two decades, one of our most popular catering pack ingredients is Purple Sweet Potato paste, used in Instagram-worthy Korean style lattes to Japanese mochis. We created the Naturalam brand to bring these ingredients to home DIY enthusiasts, and now we’re taking a further step in extending the product range to health foods consumers.

Our Technology

Our mashed sweet potatoes are cooked, packaged in specially made pouches, and thermo-stabilized in a machine known as a retort. Using carefully chosen temperature and pressure settings, the machine effectively sterilizes the food to make it shelf stable, while preserving the colour, texture, taste and nutrients.

Convenience is King

Both our catering pack sweet potato fillings and our consumer sweet potato mashes are developed with convenience in mind. We have achieved our goal of creating a cooked mash with no additives or preservatives, and with the same texture and consistency that you would expect from freshly cooked and mashed sweet potatoes, that you can take on the go without the need for freezing or reheating.
