Title: How to make spinach noodles greener
In recent years, healthy eating has become a hot topic, especially green food. Spinach noodles have become a favorite on the family table because of their rich nutrition and attractive color.

1. The scientific principle of spinach noodles turning green
The green color of spinach mainly comes from chlorophyll, but chlorophyll is easily decomposed in high temperature or acidic environment. Therefore, maintaining the green color of spinach noodles requires starting from three aspects: material selection, processing and cooking.
| key factors | influence | solution |
|---|---|---|
| Spinach varieties | Different varieties have different chlorophyll content | Choose spinach that is dark green and has thick leaves |
| Blanching time | Too long will cause chlorophyll loss | Control within 30 seconds |
| pH | Acidic environment accelerates fading | Add a small amount of baking soda (alkaline) |
| Oxidation | Easy to change color when exposed to air | Stir quickly and use as soon as possible |

| fade the next day | Dry refrigerated environment | Seal and store in plastic wrap |
5. Special tips from nutritionists
In recent discussions on healthy eating, many certified nutritionists have emphasized that although it is important to maintain color, alkaline substances should not be added excessively. Add no more than 2g of baking soda per 500g of flour, which can preserve the color without affecting nutrition. Test data shows that the optimized spinach noodles have a vitamin K retention rate of 85% and an iron retention rate of 91%.
