Effect of sodium alginate concentration on the activity of immobilized enzyme

　

　　Using the characteristics of sodium alginate solution, sodium alginate is extracted, which is mainly used as food additive, with many functions and very wide applications. Mingyue sodium alginate is common in the market. There are white and light brown sodium alginate solutions. The color depends on the specific process. It is almost transparent at low concentration and pale yellow at high concentration. Sodium alginate is alkali-resistant and acid-resistant.

　　Dilute and easy to drip, slightly sticky, forming a ball, possibly with a thin tail. It's inconvenient to operate when it's thick, just like runny nose. Factors affecting the quality: high concentration sodium alginate mixed bacteria solution is troublesome, so it needs to be stirred more. After more stirring, bubbles are brought in, which are wrapped in high concentration sodium alginate and cannot be removed at all, which affects the quality of gel beads during injection. High concentration.
