HK Food Innovation & Technology Hub (HKSTP) has recently presented its newly patented product, ProTHIX during HKTDC Food Expo PRO 2026 exhibition held in Hong Kong in August 2026.
ProTHIX is a freeze-thaw and heat-stable thickener designed specifically for soft-meal applications and is also suitable for desserts and other foods requiring controlled viscosity or thickened textures.
ProTHIX enables soft food to tolerate high serving temperatures, addressing a major pain point in the current elderly and dysphagia‑care market. At present, most soft meals can only be served warm, as they begin to melt once heated above 80°C. With ProTHIX, soft food can maintain its structure and shape even when heated beyond 80°C, allowing consumers to enjoy soft meals at proper serving temperatures.
In addition, ProTHIX is formulated with soluble fiber, resulting in lower caloric content compared with conventional thickeners. This makes it particularly suitable for diabetic individuals and clients with calorie‑control needs.
AFBR has the opportunity to interview Dr Fong Lai Ying, Director at HKSTP to find out more on this new food technology innovation. According to Dr Fong, “By 4th quarter 2026, we aim to support the food industry with ProTHIX, addressing their growing needs for stable, high‑quality soft‑meal and thickened‑texture solutions.”
Target markets for ProTHIX include elderly‑home caterers and manufacturers producing soft meals for both private and public elderly‑care institutions, with further expansion into mainstream food manufacturers and retail distribution through supermarkets. ProTHIX has versatility in many food applications. Dr Fong explained, “Most soft‑food items can be prepared, including seafood, vegetables, and meat‑based foods, to support clients who require modified‑texture meals. Potential partners are welcome to to visit us at our Hong Kong Science Park office to find out on the various applications in more details.”
ProTHIX is truly like a ‘magic thickener’ which delivers freeze‑thaw stability, high heat tolerance, and consistent performance, allowing soft foods to maintain their shape and integrity even under elevated temperatures.
The goal for ProTHIX is to deliver a high‑quality, health‑oriented solution — offering stable performance with significantly fewer calories, supporting both wellness needs and modern dietary expectations.
