Cheese
and processed cheese and their analogues
Natamycin
is most widely used in cheese, which can be classified into three methods: 1.
Spray 0.05% - 0.1% natamycin on the surface of cheese products; 2. Soak the
salted cheese in 0.05% - 0.1% concentration suspension for 2-4 minutes; 3. Add
0.05% natamycin to the coating covering cheese.
Cakes
and Pastries
Spraying
method: add 1g of natamycin to 1kg of 75% ethanol to prepare 0.1% natamycin
alcohol suspension, spray it evenly on the surface of baked cakes, cool and
pack with nitrogen.
Moon
Cake
Spraying
method: when the baked moon cake is cooled to be not hot, natamycin is mixed
into water / alcohol suspension and sprayed on the surface of the moon cake.
The
moon cakes were treated with 0.4g/kg natamycin and 8g / kg potassium sorbate.
The residues were 4.18mg/kg and 83.6mg/kg respectively.
Meat
enema
Immersion
method: 0.5g natamycin was added to 1kg water to prepare 0.05% natamycin
suspension. Then soak the casing in it for 3-5 hours before filling.
Spraying
0.05% - 0.1% natamycin suspension on the enema surface can effectively prevent
mildew on the enema surface.
Salad
dressing
Direct
addition: salad dressing is semi-solid with high fat content. Mildew often
occurs after summer. The results showed that the addition of 10 ppm (0.001%)
natamycin could effectively inhibit mold. Considering the loss of natamycin in
the production process, the recommended addition amount is 0.002%.
Soy
sauce, vinegar
Direct
addition: adding 15ppm (0.0015%) natamycin to soy sauce and vinegar can
effectively inhibit the growth and reproduction of yeast and prevent the emergence
of white flowers. Considering the loss of natamycin in the production process,
the recommended addition amount is 0.002%.
Smoked
meat products
Spraying
method: spraying natamycin suspension with concentration of 0.05% - 0.1% on the
surface of smoked and roasted meat can prolong the shelf life of the product.
Fruit
juice, fermented wine
Direct
addition: concentrated orange juice stored at 10 ℃
and 10ppm (0.001%) natamycin can inhibit the growth of yeast; When stored at
room temperature, 20 ppm (0.002%) natamycin is required to have antibacterial
effect. The recommended addition amount is 0.001-0.002%.
In
cooking wine, 3 ppm (0.0003%) natamycin can greatly prolong the shelf life.
Now
the bottleneck restricting the development of natamycin market is dissolution.
Although the low solubility of natamycin is very beneficial to food surface
treatment, it ensures that the preservative only stays on the food surface and
will not migrate to the inside of the food. However, because it is insoluble in
water, alcohol and oil, the application field and scope of natamycin are
limited. Therefore, many companies are committed to improving the solubility of
natamycin by improving the structure or dosage form of natamycin. Through the
technical breakthrough of natamycin extraction process, a high-performance
natamycin - nanocrystalline, an upgraded version of natamycin with better
solubility, more uniform distribution on food surface, more comprehensive
coverage and better preservation effect, is launched. The market is in short
supply.
In
addition to the price, the more important competition in the natamycin industry
in the future is technology improvement, including improving the extraction
process, improving the structure of natamycin and optimizing the dosage form of
products.
