The present invention belongs to the technical field of beverages, and relates to a probiotic fermented fruit and vegetable puree product. The probiotic fermented fruit and vegetable puree product is obtained by fermenting fruit and vegetable puree with Lactobacillus casei NCU215. The probiotic fermented fruit and vegetable pure provided by the present invention has the following characteristics: the probiotic fermented fruit and vegetable puree may generate a natural mellow sour, effectively remove an astringency in fruit and a wild artemisia flavor in vegetable, and neutralize an unpleasant sour in the fruit; with probiotic fermentation, the present invention may improve a content of amino acid in the fruit and vegetable by 20% or more, generate multiple aromatic substances, improve a flavor substance by 30% or more, and effectively improve a taste and a mouthfeel of the product; the present invention prolongs a shelf life of the product and prevents rot.

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 comprises a novel natural yellow colorant system to enhance the appearance of pickled and/or fermented vegetable products. Individually all-natural yellow pigments failed light stability investigations in pickled and/or fermented vegetable products—either the yellow hue of the brine solution faded, or the pulp/skin of the vegetable turned white, or both. Surprisingly combinations of these same individual natural yellow pigments not only created brine hues and vegetable coloring comparable to FD&C Yellow #5 products but remained stable in accelerated light stability investigations designed to mimic the real-time shelf-life of the products.

A method of produce washing using a short-term wash device. The method of produce washing includes processing a product through the short-term wash device followed by a wash device, applying a short-term wash treatment using the short-term wash device to the product such that the short-term wash treatment remains on the product for a pretreatment time that lasts until the product reaches the wash device, and applying a wash treatment using the wash device to the product such that the wash treatment rinses the short-term wash treatment from the product defining the end of the pretreatment time, wherein the pretreatment time is set at or below a damage threshold time beyond which the short-term wash treatment damages the product beyond a damage threshold.
