Delwa, Has the first U.S. Patent in Saffron Nanoemulsion
The present invention provides methods and compositions based on a proboscis ultrasonic homogenizer which has a high efficiency in the production of Iranian saffron nanoemulsion (Crocus sativus) to reduce droplet size in small amounts. This product was produced for the first time and the important point in this methodology is that no chemicals or unnatural preservatives areused.
A Technological Approach
Delwa method is a proboscis ultrasonic homogenizer which has a high efficiency in the production of Iranian saffron nanoemulsion (Crocus sativus) to reduce droplet size in small amounts. This product was produced for the first time and the important point in this methodology is that no chemicals or unnatural preservatives were used. The advantages of this method compared to other mechanical methods are less energy consumption, use of less emulsifier amounts and production of a more uniform emulsion with smaller droplet size.
Increasing Efficiency
Ultrasonic method of probation homogenizer in Delwa increases the production efficiency of saffron. Saffron produced based on this method has a more ideal taste and smell than the macroscopic state of saffron, more color and coloring properties compared to ordinary saffron, more lasting and stable taste than powdered and ground saffron, which ultimately the amount of saffron consumption in terms of area per unit volume is greatly reduced and saves the amount of effective substance consumed.
Benefit of Nanotechnology
Delwa is a product based on nanotechnology. Researchers are focusing their efforts on nanotechnology to address nutritional issues, given the growing consumer demand for healthy and safe food products, as well as the need for food systems with the ability to encapsulate, protect and release functional compounds. In this regard, nanoemulsion technologies are especially suitable for the construction of encapsulation systems thanks to the prevention of degradation and the preservation of biologically active substances.

Saffron Nanoemulsion
Saffron is a spice obtained from the stigmas and dried creams (Crocus Sativus L) of Crocus Sativus plant and one of the important applications of this red spice is in the food industry (transfering flavor and aroma color to food and drink) as well as use in cooking and pharmacy (due to its safety properties). The history of saffron plant production and breeding dates back to 2500 years ago.
Caviar nano packaging
Iranian caviar is one of the best and most luxurious foods that has a unique quality. Iranian caviar has long been known for its quality all over the world. This product is served as a special section of the menu in many luxurious restaurants and hotels around the world. he Caspian Sea is the main habitat of sturgeon, which supplies more than 90% of the world’s caviar.
Production Objectives of Iranian Saffron Nanoemulsion Crocus Sativus
- Reduceing the excessive consumption of this rich food
- Improving quality in order to produce the final product
- Increasing the amount of taste and color, smell and all the organoleptic properties of saffron
- Producing the smallest nanometer size possible in terms of stability in saffron essential oil
