What is the difference between freeze-dried fruit powder and spray-dried fruit powder

1, spray drying powder
Spray drying is to disperse the substance into small particles in the high-speed air flow, and then dry in the form of hot gas in the dryer to form a powder. Compared with freeze-dried powder, spray drying powder has a simple preparation process, can be large-scale industrial production, and is widely used in many fields such as cosmetics, food, chemicals and pesticides. Spray drying powder is different from lyophilized powder is that it generally has a certain amount of additives and accessories, in order to improve product quality or maintain product characteristics, in the process of spray drying will add some additives, so that cosmetics and other products are not easy to absorb moisture. Spray drying powder has more additives. Spray drying powder is more widely used in cosmetics, food, chemical and pesticide and other fields.

2, freeze-dried powder
Freeze-dried powder is a kind of powdered food additive made from juice or pulp after dehydration, purification, quality improvement treatment, and freeze-drying. It has antioxidant, thickening, stability and other functions, can be widely used in a variety of foods, is also one of the important factors to ensure food quality and taste.
The advantages of freeze-dried powder mainly include its ability to preserve bioactive ingredients well, with deep penetration and rapid absorption, which makes it have significant effects in the field of skin care. The freeze-dried powder, through the process of rapid freezing and vacuum drying, can retain the activity of the active ingredient to the maximum extent, ensuring its stability and efficacy. In addition, freeze-dried powder does not need to add too many preservatives, so it is relatively safer. However, freeze-dried powder also has some disadvantages, such as a higher price and the need for refrigeration.
Freeze-dried powders are commonly used in the field of biological products and medicine because they retain the structure and activity of the original items, such as the various juice freeze-dried powders we offer.
