This can be a significant selling point for products in the current market where consumers are increasingly interested in natural and minimally - processed foods.

2.2 Color Stability

• Another advantage of using Lithospermum erythrorhizon extract as a colorant is its relatively good color stability. During the production, storage, and distribution of food products, maintaining a stable color is crucial. The extract can resist certain environmental factors such as light, heat, and pH changes to a certain extent, ensuring that the color of the food remains consistent over time. For example, in baked goods, where high temperatures are involved during the baking process, the Lithospermum erythrorhizon extract can still maintain its color better than some other natural colorants, which may fade or change color under such conditions.
• However, it should be noted that the color stability of the extract may also be affected by other factors in the food matrix, such as the presence of certain enzymes or other ingredients. Therefore, further research is needed to optimize its use in different food systems to ensure maximum color stability.

3. Antioxidant Capacity

3.1 Free Radical Scavenging

• The antioxidant capacity of Lithospermum erythrorhizon extract is one of its most important properties in the food industry. Free radicals are highly reactive molecules that can cause oxidative damage to food components, including lipids, proteins, and carbohydrates. In food systems, the presence of free radicals can lead to rancidity, loss of nutritional value, and deterioration of sensory qualities. The extract contains various antioxidant compounds that can effectively scavenge free radicals. For example, phenolic compounds present in the extract can donate hydrogen atoms to free radicals, thereby neutralizing them and preventing further oxidative reactions.
• In processed fruits and vegetables, the antioxidant activity of the Lithospermum erythrorhizon extract can play a crucial role. These products are often more susceptible to oxidative damage due to the processing steps such as cutting, peeling, and heat treatment. By adding the extract, the shelf - life of processed fruits and vegetables can be extended. The extract can protect the natural colors, flavors, and nutrients of the products, maintaining their quality for a longer time.

3.2 Interaction with Other Food Components

• When added to food, the Lithospermum erythrorhizon extract may interact with other components. For example, it may interact with lipids in food, forming a protective layer around them. This interaction can prevent the lipids from being oxidized by free radicals or other oxidative agents. Similarly, it can also interact with proteins, potentially affecting their structure and functionality. However, more research is needed to fully understand these interactions and how they can be optimized to achieve the best antioxidant effects in different food products.
• Furthermore, the antioxidant activity of the extract may be influenced by the overall composition of the food. For instance, the presence of certain minerals or vitamins in the food may enhance or inhibit the antioxidant capacity of the Lithospermum erythrorhizon extract. Understanding these complex interactions is essential for the successful application of the extract in the food industry.

4. Prebiotic - like Effect

4.1 Promotion of Beneficial Gut Microbiota

• Recent research has suggested that Lithospermum erythrorhizon extract may have a prebiotic - like effect. When added to fermented foods such as yogurt, it has the potential to promote the growth of beneficial gut microbiota. The gut microbiota plays a vital role in human health, influencing digestion, immunity, and overall well - being. Beneficial bacteria such as Lactobacillus and Bifidobacterium can ferment certain components in the Lithospermum erythrorhizon extract, producing short - chain fatty acids (SCFAs) such as acetate, propionate, and butyrate.
• These SCFAs have numerous health benefits, including improving gut barrier function, reducing inflammation, and providing energy to the cells lining the colon. By promoting the growth of these beneficial bacteria, the Lithospermum erythrorhizon extract can contribute to the development of healthier fermented foods. This is in line with the current trend of developing functional foods that not only provide basic nutrition but also offer additional health benefits.

4.2 Impact on Fermentation Process

• In the fermentation process of foods like yogurt, the addition of Lithospermum erythrorhizon extract may also affect the fermentation kinetics. It can potentially influence the growth rate and metabolic activity of the fermenting microorganisms. For example, it may alter the production of lactic acid, which is an important factor in determining the acidity and texture of yogurt. If the growth of beneficial bacteria is enhanced by the extract, it may lead to a faster fermentation process and a more stable product.
• However, the impact on the fermentation process needs to be carefully studied and optimized. Different strains of microorganisms may respond differently to the addition of the extract, and the concentration of the extract also plays a crucial role. Too high a concentration may have inhibitory effects on the fermentation, while too low a concentration may not achieve the desired prebiotic - like effect.

5. Challenges and Future Directions
