Abstract

The β-glucan freeze-thaw gel has been used as a carrier to release curcumin. The freeze-dried gel has the ideal sustained release following 5% β-glucan solution by adding 1% β-glucan quality curcumin, repeated freezing and thawing 8 times. The Peppas equation can significantly describe the release mechanism of curcumin in the β-glucan gel. This study further shows that the release of curcumin in the oat β-glucan gel is the Fick diffusion mechanism and coated barley β-glucan is a non-Fick release. Trying to use β-glucan as a completely natural drug delivery carrier opens up new ideas for the use of β-glucan.

Highlights

  • Oat, known as oat, is a kind of nutritious food in cereals [1]

  • The ammonium sulfate precipitation method makes it difficult to completely precipitate β-glucan [31], so the measurement results are lower than normal levels

  • The H protons resonate with the emitted radio frequency to absorb the pulse energy

Summary

Introduction

Known as oat, is a kind of nutritious food in cereals [1] It enjoys cold and warm climate conditions and is one of the important food crops in China [2]. Oats have high nutritional value and are rich in health-friendly ingredients [3]. They are hailed as the best full-price foods in cereals. A large number of studies have confirmed that β-glucan has important physiological functions It can promote the proliferation of probiotics, prevent colon cancer [13], reduce blood lipids and cholesterol [14], regulate blood sugar [15,16], improve immunity, anti-aging and moisturizes the skin [17,18]
