Sesamin powder is a natural pigment obtained from black sesame (Sesamum indicum; S. orientale: a.k.a. flax, sesame, linseed, jusheng, etc.) by modern biotechnology. It is a safe, non-toxic, stable and excellent natural melanin. Water mainly contains flavonoids and anthocyanins. It is a glossy black powder that is easily soluble in water. In addition, black sesame anine has good antioxidant effects, scavenges free radicals, reduces blood fat, anti-tumor and other functions, and can be used as a pigment additive for food, medicine and health products, with broad development prospects. And application value.
Black sesame anin is not only natural melanin, but also has nutritional value and pharmacological action, especially strong antioxidant effect. In recent years, with the continuous improvement of consumers' food safety awareness, people have placed more and more emphasis on pure natural foods, nutritional values and healthy foods. Therefore, the development of black sesame seeds is in line with the trend of modern consumers to pursue edible pigments.

1.1 Main components

It mainly contains flavonoids anthocyanins.

1.2 Features

1) Good acceptance
2) Stable in light and heat,
3) Sugar and salt tolerance,
4) Security

3.1 Used as a food additive
1)Black sesame pigment LD50>10000mg/kg. At present, the black sesame pigment developed in China has entered the industrialization stage, mainly including paste and powder products. In the food industry, black sesame pigment is one of the natural food pigments, widely used in black food coloring, functional food development and health food. It can also be used as black bone fried chicken essence (0.03%) and black bone fried chicken oral liquid, such as black cake (0.05%~0.1%) biscuit (0.05%) instant noodles (0.05%~0.06%). (0.02%~0.04%).

2)Natural black sesame melanin is also widely used in the food industry, and it can be used as an additive in wine, beverages, baby health products and public food. For example, the natural melanin in black sesame is extracted, and then mixed with wild fruit juice to form a black drink, which enriches the nutritional content and maintains the natural color.

3.2 Used as a raw material for domestic chemical products
1) Because of its excellent physical and chemical properties, black sesame pigment has also been well used in daily chemical industry. It is made of creamy black sesame pigment as raw material and mixed with anti-inflammatory drugs (contains melatonin 8%~10%). After fermenting, it can also make hair smooth and smooth, and has a certain effect on hair care and hair coloring. In addition, black sesame pigment can also be used to produce eyebrow pencil, lipstick, black sesame soap, etc.
Safety and capacity: product, no side effects.

2) Natural black sesame anin has sunscreen function and can be used in daily cosmetics industry to make sunscreen and sunscreen.

3.3 Black sesame anine has the properties to generate free radicals and to combine with potentially toxic cations (such as some transfer metals), allowing it to be used as a protective chemical pigment.

3.4 Health food industry
Black sesame melanin has anti-oxidation and anti-aging functions, which will greatly promote the application of natural melanin in the health food industry that is increasingly valued.

3.5 Melanin can be used as an amorphous semiconductor, a protective agent for biopesticides, etc.

3.6 Black sesame melanin is often used as a potential target for anti-melanoma therapy. Recently, it was found that melanin has the effect of inhibiting apoptosis induced by influenza virus in vitro. In recent years, it has been found that some soluble melanin has a significant inhibitory effect on HIV in vitro, and scientists believe that soluble melanin may become a new type of effective drug.

1) Light stability
Expose the pigment solution extracted under acidic, alkaline and neutral conditions to sunlight and measure the absorbance value of each solution at intervals. After 16 days, the light absorption value drops below 3%, indicating that the pigment has good light stability.

2)Thermal stability
The absorbance changes of the pigment solution extracted under acidic, neutral and alkaline conditions were determined after maintaining 50°C, 70°C and 100°C for 1h, 2h and 4h. High temperature reduces the absorption value of the pigment solution. The higher the temperature, the longer the time and the lower the absorption value. In addition, under alkaline conditions, the thermal stability of the extract is poor, especially at a high temperature of 100°C and a long time of 4 hours, the absorption of the alkaline extract decreases sharply, with a maximum decrease of 25.4.

3). Effects of pH
Adjust the pH of the pigment solution with HCl or NaOH and measure the absorbance of the solution. As the pH increases, the light absorbance of the pigment solution increases and the color darkens. However, the extract under alkaline conditions will precipitate when the pH is 3, and the color of the solution will also become lighter.

4). Oxidation resistance
Prepare a certain concentration of pigment solution, add 30% hydrogen peroxide solution or leave it at room temperature for 2h, 4h, 8h and 24h. The measured concentration is 0.06%, 0.12%, 0.24%, 0.48% and 0.96%. The light absorption of the solution value changes. The results showed that with the increase in the hydrogen peroxide concentration and the lengthening of the storage time, the absorbance value gradually decreased, but the maximum value was not more than 4.5% (0.96% hydrogen peroxide, 24h), and the pigment had good oxidation resistance.

5). Decrease resistance
Prepare a specific concentration of pigment solution, add sodium sulfite solution to make the concentration 0.1 mol/L, 0.2 mol/L, 0.4 mol/L, 0.6 mol/L respectively, and place them at room temperature for 2h, 4h , 8h, 24h, and measure the light absorbance of the solution value change. The results show that the maximum change in absorption value A of the pigment solution is not more than 4%, and the pigment has good resistance to reduction.

6). Sugar tolerance
Prepare a certain concentration of pigment solution, add different amounts of sucrose solution to make the concentration of 5%, 10%, 20%, 30%, 40% and 50%, and then measure the absorbance value of the solution. Leave at room temperature for 3 days. The results show that the light absorption value A of the pigment solution shows little change and the pigment has excellent sugar tolerance.

7). Salt resistance
Prepare a certain concentration of pigment solution, make the concentration of 5%, 10%, 20%, 30%, 40% and 50% according to the amount of salt solution, and put it at room temperature for three days to its change to determine. The absorbance value of the solution. The results show that the light absorption value A of the pigment solution has little change and the salt resistance of the pigment is good.

8). Effect of Metal Ions
Prepare a certain concentration of pigment solution, add Fe2+, Cu2+, Mg2+, Ca2+, Al3+, Fe3+, Zn2+, Na+ and other metal ions, and determine the absorbance of the solution after three days. The results show that the usual metal ions mentioned above do not affect the stability of the pigments.
