Disclosed is a natural compound sweetener, comprising mogroside V, rebaudioside A, natural tea theanine and dietary fibre. The method for preparing the sweetener comprises the steps of: (1) dissolution, filtration, concentration and sterilization: dissolving the mogroside V, rebaudioside A, natural tea theanine and dietary fibre in water, filtering, concentrating in a vacuum, and sterilizing to obtain a sterilized solution; and (2) paste-collection, drying and granulation: carrying out paste-collection on the sterilized solution obtained in the step (1), vacuum drying the collected liquid paste, and drying and then granulating the dry powder to obtain the sweetener.

A method for the thermal treatment of bulk materials in a rotary tube with at least one infrared light unit. Bulk material is introduced into the rotary tube, which is provided on its inner wall with at least one mixing element and in the interior space of which the pressure of the ambient atmosphere prevails. A heat treatment of the bulk material is performed by at least one electrical infrared light unit, which is arranged at the center of the rotary tube and the light cone of which is directed onto the bed of bulk material that lies on the inner wall of the rotary tube. The bulk material is discharged from the rotary tube. Water vapor is directed onto the surface of the bulk material. The vapor is introduced into the interior space of the rotary tube through a nozzle tube.

A MATZHU is prepared by using leaves of Gramineae (Graminae) and Bambusoideae plant as raw materials. The MATZHU has a stable emerald color and an average powder particle size of 800 to 10,000 meshes. The MATZHU also has a total amount of dietary fiber of ≥60%, a content of lignin of ≥20% and a content of minerals of ≥7%. The MATZHU includes 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 includes, 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.

The present invention relates to a method for three-dimensional microwave air-jet drying of persimmon slices, comprising steps of grading and cleaning, slicing, microwave heating, steam de-astringency, hot-air reverse primary drying, negative-pressure intermittent secondary drying, cooling and packaging. In the present invention, high-temperature (60-70° C.) high-pressure annularly sprayed citric acid and 40% alcohol vapor (rotating at 360°) are adopted to remove astringency of persimmons, wherein high temperature causes more intense Brownian motion of liquid molecules; high pressure improves permeation and diffusion speed of de-astringency liquid in the persimmon slices; citric acid plays a membrane breaking role on persimmon cell membranes; and 40% alcohol vapor is allowed to rapidly diffuse into cells, so that tannin is polymerized into insoluble gel from a soluble state, thereby achieving a uniform and rapid de-astringency effect.

The present invention involves a new method to produce pure coconut powder. Under ultra-high-pressure condition, the fiber of coconut meat shortens and puffs, consequently, its specific surface area increases. This enhances its ability to absorb fat, which enables the natural fiber in coconut meat to act as the excipient (carrier) of spray drying or lyophilization (whereas in traditional coconut milk powder formulations, art starch hydrolysates are added to act as the excipient). Further the natural fiber replaces emulsifiers and anti-caking agents used in the traditional formula. This produces a pure coconut powder that has no foreign additives, but at the same time has a good instant solubility and reconstitution stability, as well as possesses rich dietary fiber. This invention produces no by-product (desiccated coconut), realizing the zero-residue processing of coconut meat.

A dried powder of an edible plant which hardly gets damped, without relying on a substance other than a dried edible plant serving as a main food material for imparting features to a flavor and a color tone of a dried powder, and a method for producing the same is provided. The dried powder contains an edible part and a non-edible part of a dried edible plant which a proportion of the non-edible part to the edible part of the dried edible plant is 1% by mass or more and 200% by mass or less, a repose angle is 0.7 rad or more, loose bulk density/tight bulk density is 0.88 or less and a moisture content is 20% by mass or less.

Described are dried cranberries with reduced sugar content, while retaining a desired sweetness and texture, and methods of making such dried cranberries. Dried cranberries include erythritol and a sweetener that interferes with erythritol crystallization.

A method of manufacturing green pepper powder is disclosed. The present disclosure relates to a method of manufacturing green pepper powder, which cleans green-colored peppers, removes the pepper stems and seeds, lyophilizes the green-colored peppers without stems and seeds under predetermined conditions, and pulverizes the lyophilized product to manufacture green pepper powder.

The disclosure relates to a high-bioactivity black dry apple chip and a processing technology thereof. The processing process is as follows: fresh fruits.fwdarw.sorting.fwdarw.peeling.fwdarw.slicing.fwdarw.fermenting.fwdarw.drying.fwdarw.packaging.fwdarw.black dry apple chips. According to the disclosure, a high-temperature Bacillus subtilis fermentation broth atomization spray technology is adopted to atomize the processed apple slices under the condition of 60° C.-80° C., the cut apple slices are irradiated with 60 Coy rays at a dose of 4 kGy to promote carbonyl ammonia reaction so as to make apple slices generate burnt black. According to the disclosure, Bacillus subtilis antimicrobial peptide solution is sprayed so as to utilize its bacteriostatic function to avoid pathogen infection during shelf life.
