AI Technical Summary

Technical Problem

In existing technologies, the extraction and microencapsulation of morel mushroom active ingredients suffer from low extraction efficiency and poor stability. In particular, proteins are easily deactivated by factors such as temperature, pH, and oxygen during processing, storage, and in vivo digestion, resulting in reduced bioavailability. Furthermore, the microencapsulation process has not been precisely optimized for the characteristics of morel mushroom extracts.

Method used

The ultrasonic-assisted extraction process parameters and the ion gel microencapsulation process parameters were optimized using response surface methodology. By optimizing the material-liquid ratio, ultrasonic power, extraction temperature, sodium alginate addition, calcium chloride concentration, and pH value of the curing solution, highly efficient microcapsules of morel active ingredients were prepared, forming a dense calcium alginate gel network to achieve stable encapsulation and sustained release of the active ingredients.

Benefits of technology

It significantly improved the protein yield of morel mushrooms, enhanced the antioxidant activity of the extract, and maintained good stability under refrigeration conditions, achieving efficient protection and sustained release of the active ingredients of morel mushrooms.

Abstract

An optimized method for the extraction and microencapsulation of morel mushroom active ingredients, relating to the field of extraction and microencapsulation technology, employs response surface methodology. Using protein yield and protein encapsulation rate as response targets, it precisely obtains the optimal combination of process parameters for ultrasonic extraction and ion gel microencapsulation, achieving rapid, systematic, and model-based optimization of all process parameters from extraction to encapsulation of morel mushroom active ingredients. A microcapsule of morel mushroom active ingredients and its preparation method are also provided. Using the optimal process parameters obtained by this optimization method, ultrasonic-assisted extraction and ion gel encapsulation are performed, achieving stable and reproducible preparation of high-performance morel mushroom protein-calcium alginate gel microspheres. The prepared morel mushroom active ingredient microcapsules form a dense calcium alginate gel network internally, with the active ingredients and wall material firmly bound through hydrogen bonds and other interactions. They exhibit good storage stability under refrigeration conditions, achieving effective protection, sustained release, and high-value utilization of morel mushroom active proteins.
