"Phu Si" products


The product line "Phu Si" by Ajinomoto Vietnam was first introduced in 2012. Up to the present time, this product line has developed and launched three main products on the market: "Phu Si" soy sauce,  "Phu Si" less salt soy sauce, and "Phu Si" traditional soy sauce.

Ajinomoto Vietnam always focuses on using the finest ingredients for its products. Therefore, for the "Phu Si" line, we use whole soybeans and rigorously inspected rice according to standardized processes before they enter the production process. Particularly, we also apply the kiage method - 100% natural fermentation for 3 months, following traditional Japanese technology. This process helps create "Phu Si" products with exceptional quality and distinctive flavors, aimed at satisfying consumers.

"Phu Si" Less salt 

Since October 2023, Ajinomoto Vietnam proudly introduced the reduced-salt version of "Phu Si" soy sauce. This is a new product with salt reduction technology while maintaining the delicious, harmonious, fragrant, and rich flavor consistent with the original "Phu Si" soy sauce.

The reduced-salt version of "Phu Si" soy sauce is an ideal choice for those concerned about health, notably reducing salt content by up to 30% (*) while preserving the sweet and mellow taste, thanks to the base ingredients of Kiage naturally fermented for over 3 months from whole soybeans and rice following traditional Japanese processes.

Production process


The success of Ajinomoto Vietnam's "Phú Sĩ" product line doesn't solely rely on careful ingredient selection but also on advanced manufacturing processes and technology. "Phú Sĩ" soy sauce, "Phu Si" Less salt , and "Phu Si" Xi Dau all utilize carefully selected whole soybeans and rice before being introduced into the production line to ensure the quality of the end product.

This process is the secret behind the rich taste and natural aroma of the soybeans.
