Abstract
This invention relates to the field of food technology, providing a high-concentration sterile lactoferrin solution and its preparation method. The lactoferrin solution contains at least 5% lactoferrin by mass and includes a compound stabilizer composed of sodium alginate and histidine in a mass ratio of (2-5):1. This invention utilizes the synergistic effect of sodium alginate and histidine to construct a stable system for the high-concentration lactoferrin solution. This allows the lactoferrin solution with a mass content of at least 22% to remain free from flocculation and precipitation during its shelf life, without any reduction in activity.
