High-purity, RCEP-compliant plant protein isolates specifically engineered for stability, solubility, and strict sensory profiles.
Japan's food and beverage market is undergoing a seismic structural shift. Driven by a rapidly aging population, rising concerns over lifestyle-related diseases, and a national push towards sustainable, clean-label raw materials, major Japanese food corporations are actively seeking alternatives to traditional soy and wheat proteins.
Soy allergy awareness and the demand for non-GMO, allergen-free labeling have elevated Fava Bean Protein (known locally as Sora-mame そら豆) to a position of high commercial interest. Unlike soy, which is a major allergen in Japan, fava bean protein offers a clean immunological profile while matching or exceeding the functional properties required by Japanese culinary standards.
"By utilizing advanced enzymatic extraction, our fava bean protein achieves up to 90% purity, rendering a highly neutral flavor profile compatible with sensitive Japanese sensory expectations."
How our advanced manufacturing line in China ensures structural and nutritional consistency for demanding Japanese buyers.
We utilize multi-stage wet milling followed by proprietary low-temperature centrifugation. This completely avoids chemical modification, preserving the natural globulin/albumin structures for high water solubility and natural emulsification.
Fava beans typically contain vicine and convicine which affect taste. Our targeted enzymatic pre-treatment and thermal deodorization process neutralizes beany off-notes, ensuring the protein can be incorporated seamlessly into Japanese matcha beverages, oat milks, and standard bakery items.
To meet the strict Positive List System of Japan's MHLW, every batch of fava bean protein undergoes ICP-MS heavy metal detection and a 500+ multi-residue pesticide screen before export clearance.
Tailoring nutritional density and functional behavior to traditional and modern Japanese food sectors.
Our water-soluble fava protein isolate powder exhibits excellent dispersibility and suspension stability in aqueous phases. Ideal for high-end beauty supplements, elderly care protein mixes (sarcopenia prevention), and ready-to-drink (RTD) wellness beverages in Japan.
Excellent texture modifier and creaminess enhancer. With 85-90% protein contents, it creates a thick, satisfying mouthfeel in almond, oat, and coconut milk formulations without introducing soy or dairy allergen warnings.
Replaces egg whites and gluten binders in Japanese confectionery (Wagashi and Western-style baked goods). Provides structural integrity, crumb softness, and high water-holding capacity to maintain product freshness during distribution.
