A MATZHU is prepared by using leaves of Gramineae (Graminae) and Bambusoideae plant as raw materials, and has a stable emerald color, and has an average powder particle size of 800 to 10,000 meshes, and has a total amount of dietary fiber of ≥60%, a content of lignin of ≥20% and a content of minerals of ≥7%, and comprises at least three or more bamboo leaf characteristic components, such as orientin, isoorientin, vitexin, isovitexin, adenosine, δ-hydroxylysine and p-coumaric acid. The method for the MATZHU preparation comprises, in turn, performing blanching and color protection, drying and superfine grinding the raw materials. By utilizing the thermal stability and the light stability of the MATZHU, the MATZHU may be used as a raw food material, a functional ingredient, or a dietary supplement.

Fine bamboo powder and preparation method therefor and use thereof

Disclosed is a method for constructing fluorescentsilkworm silk irradiated by near-infrared light and its products, comprising: (1) preparing upconversion nanoparticles, and performing surface modification with concanavalin to obtain modified upconversion nanoparticles; (2) uniformly dispersing the modified upconversion nanoparticles in water to formulate an aqueous solution of the upconversion nanoparticles, (3) picking mature mulberry leaves, immersing the mulberry leaves in the aqueous solution system of the nanoparticles, leaching water, and naturally drying the mulberry leaves; (4) after silkworms have grown for a set time, feeding the treated mulberry leaves to the silkworms until the silkworms spin silk cocoons; and (5) collecting the silk, so as to obtain mulberry silk that fluoresces under near-infrared light. The present invention selects upconversion nanoparticles capable of emitting fluorescence under the irradiation of near-infrared light which has stronger penetration, thus has better application in deep tissue imaging.
