The invention relates to an oral solution having high SOD enzymatic activity and the preparation method therefor, wherein the method comprises: pressing edible plant raw materials, followed by removing large particles by means of centrifugation (1000-4000 rpm, 0-30 min); subsequently, separating the supernatant using two processes of ultrafiltration (the first separation adopting a tubular membrane with pore size ranging from 60-120 kD; the second accomplished by an spiral-wound membrane with pore size ranging from 8-30 kD), before treated using ultra-high pressure at 200-600 MPa for a period of 1-20 min. After treated by the method of the invention, SOD has been activated with enhanced enzymatic activity up to above 10000 U/ml, which has addressed problems related to low enzymatic activity of SOD in products. The products obtained by the present method are more beneficial to human health.

A fermented sparkling vinegar beverage includes a fermented solution formed of 0 vol % of to 15 vol % of raw vinegar, 3 vol % of to 15 vol % of sugar, 0 vol % of to 5 vol % of honey, 0 vol % of to 0.3 vol % of salt, 0 vol % of to 40 vol % of plant extracts, 1 vol % of to 5 vol % of yeast liquid, and water. Composition of yeast liquid varies according to different product flavors; yeast strains are selected from Saccharomyces cerevisiae, Hanseniaspora osmophila, Hanseniaspora valbyensis, Torulaspora delbrueckii, and Dekkera bruxellensis in different ratios, and the yeast strains generate metabolite and produce bubbles in the fermented solution. Therefore, the present invention brews the fermented solution by yeast liquid formed of various yeasts, applying the metabolites and bubbles generated through fermentation of the yeast strains to alleviate sour content of the raw vinegar, so as to improve the drinking taste of the fermented solution.

Provided are a polyphenol-rich and low-sugar beverage of fermented jujube pulp and a preparation method thereof. The fermented jujube pulp beverage is prepared with a method including the following steps: (1) selecting jujubes that are free of rot and are not insect-eaten, rinsing with pure water, pre-boiling in boiling water, and removing cores; (2) beating the jujubes whose cores are removed in step (1) into a beating machine to obtain a jujube pulp; (3) pouring the jujube pulp in step (2) into a colloid mill for processing to refine jujube peels to obtain a refined jujube pulp; (4) subjecting the refined jujube pulp to ultra-high-pressure sterilization; and (5) inoculating Streptococcus thermophilus into the jujube pulp after the sterilization in step (4), and performing a fermentation cultivation to obtain a fermented jujube pulp.

The present disclosure relates to a method for producing pulp-containing juice, which may produce pulp-containing juice without loss of nutrients while maintaining the flavor and color of a raw material. The method includes squeezing raw material for juice to obtain juice and sterilizing the juice by non-thermal high-pressure processing. Thus, the method may inactivate microorganisms or enzymes, maintain the quality of the juice in a fresh state, and prevent the flavor and nutrients of the raw material from being lost by high-temperature sterilization. In addition, through a quick freezing process, it is possible to prevent the layer separation phenomenon from occurring, prevent the nutrients from being destroyed by temperature changes, and maintain the uniform color of the pulp-containing juice even without using a colorant. A user can conveniently drink the pulp-containing juice produced by this method while feeling the flavor of the fruit thereof without loss of nutrients.
