Formation of low-crystallinity phytosterol nanoparticles via cooling-controlled supercritical carbon dioxide (SCCO.sub.2) impregnation of phytosterols into biodegradable nanoporous starch aerogels and methods of preparing these aerogels are disclosed. The nanoporous starch aerogels increase water dissolution and bioaccessibility of the phytosterols, thereby making them available for preparation of high nutraceutical value foods.

A health-care preparation simultaneously with magnesium supplement and antioxidant functions and a preparation method thereof are disclosed. The health-care preparation comprises a main active ingredient of magnesium agent and an excipient. The magnesium agent is MgH.sub.2 micro-nano powder, and the excipient is a commonly used dietary supplement auxiliary material. Compared with the existing magnesium-supplementing preparation, the health-care preparation can simultaneously supplement magnesium which is the essential trace element in human body, and hydrogen which can neutralize oxygen free radicals. The present invention has the following advantages: it is convenient for storage and taking, and has a high conversion and absorption efficiency, a low cost, and no toxic side effects. Long-term use of the preparation can effectively prevent a variety of adverse symptoms caused by magnesium deficiency, moreover the introduction of hydrogen which has an antioxidant effect can benefit to anti-inflammatory, body health, anti-aging and prevention of disease.
