Abstract

The invention discloses lycopene nanopwoder and a preparation method thereof. The powder is prepared from a lycopene nanoemulsion by a spray drying method, during preparation, the air inlet temperature is 170-210 DEG C, the air outlet temperature is 65-105 DEG C, and the feeding rate is 10-30 mL / min. The method is simple to operate, after the prepared lycopene nanopwoder is stored for one month under a normal-temperature shading and drying conditions, the load rate of lycopene in the nanopowder can still reach 60%, the retention rate can be higher than 80%, the increase amplification of the average particle size is 165 nm, the storage stability is high, the nutrient content is high and the ion stability and sucrose stability are high, indicating that the dried lycopene nanopowder constructed by the method has application potentials in food systems and is suitable for large-area promotion and application.

Description

technical field [0001] The invention belongs to the technical field of functional nutritional food preparation technology. More specifically, it relates to a lycopene nano powder and a preparation method thereof. Background technique [0002] Lycopene (lycopene) is a kind of carotenoid, which has a wide range of biological activities. Research reports have continuously discovered and confirmed that lycopene has various effects such as preventing and treating cancer, preventing and treating cardiovascular diseases, and enhancing immune activity. However, the properties of lycopene limit its application to a large extent, and water insolubility and instability are the two most important factors, which largely limit its application. [0003] Nanoemulsion is a thermally unstable system with a particle size in the range of 50-200nm. It has good stability and is often in a transparent or translucent state. It is suitable for adding to various food and beverage systems. But after...
