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.

Controlling the production of an extract using solid-liquid extraction that improves the exchange of material during the extraction process and allows a controlled dehumidification of a raffinate with residual moisture in order to obtain additional valuable extract is described. The steps include providing a first mass in an extraction container, supplying a second mass to the first mass without spatial constraints and distributing and mixing the second mass into and with the first mass, discharging a mixture of the extract and the raffinate from the extraction container, separating the discharged mixture into the raffinate with residual moisture and extracts released from the raffinate with residual moisture, and further treating the raffinate with residual moisture at least such that the residual moisture consisting of the extract is at least partly removed from the raffinate with residual moisture by dehumidification and is supplied to the already separated extract.

A granular composition containing dietary fibers derived from green tea and a method for preparing the same are provided. The granular composition may be prepared into granules, which has a suitable size and a shape to eat, using processed green tea having an insoluble dietary fiber content of 70% by weight or more; and a sugar alcohol as raw materials. The granular composition may also be useful in solving the problems such as dust scattering, throat choking, and the like due to the good flowability of the granules, and useful in manufacturing articles because the granular composition is easy to quantify due to the good filling properties.

The industrial production of an extract by means of solid-liquid extraction improves the exchange of substances during extraction and allows enhanced dehumidification of a raffinate with residual moisture.

The extraction is enhanced during a first dwell time by at least partially flooding a vessel in the form of at least one flow discharged with a secondary solvent or the obtained extract, swirling and keeping in suspension the primary mixture within the vessel by supplying the secondary solvent or the obtained extract via a foot area of the vessel, and/or moving the vessel relative to the extraction container within the obtained extract.

The secondary solvent or the extract circulates in the extraction container by a circulation guide incorporating the extraction container from top to bottom relative to the extraction container, and the extract freed from raffinate with residual moisture obtained by dehumidification is supplied to the separated or to be separated extract.

A granular composition containing dietary fibers derived from green tea and a method for preparing the same are provided. The granular composition may be prepared into granules, which has a suitable size and a shape to eat, using dietary fiber-containing processed green tea, an oligosaccharide and a sugar alcohol as raw materials. The granular composition may also be useful in solving the problems such as dust scattering, choking, and the like due to the good flowability of the granules, and manufacturing goods because the granular composition is easy to quantify due to the good filling properties.

This disclosure relates to methods, systems and compositions for food coloring. Embodiments disclosed herein may include methods and systems for combining tea leaves and water to form a feed slurry; processing a feed slurry to at least partially remove a tea essence from the feed slurry, thereby obtaining a tea extract with a predetermined amount of one or more of an aroma or a flavor; and adjusting a color of the tea extract, thereby obtaining a coloring agent with a predetermined color-related feature, wherein the coloring agent is added in a predetermined amount to a food product to adjust a color of the food product. Embodiments may also including coloring compositions, which may include a dry tea extract, wherein an essence has been removed from the dry tea extract to a predetermined amount, and a color of the dry tea extract has been adjusted to have a predetermined color-related feature.
