Soy lecithin powder is a substance derived from soybeans that is commonly used as an emulsifier, stabilizer, and thickener in food products. It is a natural source of phospholipids, which are essential components of cell membranes. Soy lecithin powder is often added to chocolate, baked goods, and other processed foods to improve texture and prevent separation of ingredients. It is also used in the production of dietary supplements and pharmaceuticals. Soy lecithin powder is generally considered safe for consumption, although some people with soy allergies may need to avoid it.

When strawberry is introduced, it needs to pay attention to eight points
Strawberries come in a wide variety, with new types constantly emerging and being introduced. Due to their extensive growing range and diverse production methods, it's essential to carefully consider several key factors when introducing new strawberry varieties. Here are eight important points to keep in mind:
1. **Choose based on purpose and environment**: The selection of a strawberry variety should be based on the intended use, local climate, and available facilities. For open-field cultivation aimed at selling fresh fruit, look for large, early-maturing, high-yield, flavorful, aromatic, and visually appealing varieties with strong disease resistance and good storage qualities. In northern regions, frost resistance is crucial, while in the south, heat tolerance is more important. For greenhouse or protected cultivation, opt for varieties that offer superior quality, long harvest periods, and high yield, such as Zhangji, Fergenia, Tudela, Hada, Daselekte, and Tongzi No. 1.
2. **Select compatible pollinators**: Introduce varieties that have high economic value and good pollination compatibility. A mix of early, mid, and late-season varieties can improve pollination, increase yield, and extend the supply period, helping to balance market demand and labor needs. Pollinator varieties should make up around 20% of the total planting.
3. **Ensure reliable sources**: Always obtain seedlings from official or trusted sources rather than buying randomly from the market. It’s best to directly contact the original breeder or a reputable nursery for on-site inspection and expert guidance.
4. **Gather detailed information**: Provide comprehensive data about the introduced varieties, including their genetic background, historical performance, and adaptability. This helps predict how well they will perform in your specific region.
5. **Use approved domestic varieties**: Prefer varieties that have been officially tested and approved at the provincial level, or those that have shown excellent results in local trials and are widely cultivated.
6. **Opt for healthy, virus-free seedlings**: Choose seedlings that are free from viruses and of high quality. Ideal seedlings should have 6–8 leaves, a rhizome thickness of 1.2–1.5 cm, and a weight of 25–30 g. For sandy loam soils, larger seedlings (8 leaves, rhizome over 1.5 cm thick, weight over 40 g) grown in clay fields are preferable.
7. **Avoid pests and diseases**: Be cautious of misidentification due to multiple names for the same variety. For example, Dacekrit Century 1, Maria, Ghost Ngan, Zhang Ji, Ferguña, and Spring Star are all different names for similar varieties. Proper identification is essential to prevent duplication and ensure quality.
8. **Conduct local trials first**: Before large-scale introduction, conduct comparative trials in your area for at least three years. Only after confirming their value should you proceed with wider adoption.
In addition, choose the right time for introduction, ideally starting with nearby sources. Handle and transport seedlings carefully, and plant them as soon as possible to maintain their health. Also, regularly update your variety selection to meet changing market demands. For instance, if there's a growing need for processed strawberries, select varieties like Eden, Early Red Light, or others that are suitable for canning, with firm texture, uniform size, and rich flavor.
