Benefits of technology

This patented technology uses special liquids that are effective against harmful microorganisms such as yeast or mold spores. These fluids have certain concentrations of ethanol added thereto while being able to effectively dissolve any unwanted substances found inside them without affecting their flavorings or colors. They provide an easy-to use solution by providing consistently high levels of germicidal agents (ethylene oxide) throughout the entirety of each part of lycii root. Overall, these technologies improve the quality and safety of crops grown indoors where they're kept outdoors due to its ability to prevent diseases caused by fungi.

Problems solved by technology

The technical problem addressed by this patented technology relating to processed nonfood products like dark green berries involves removing any polluted substances during production processes while preserving beneficial components within those items. Current options include direct rinse or wetting techniques, including hot water immersion, coldwater immersion or warm air exposures, followed by physical removal through abrasion or grinding tools. However these treatments may damage some valuable compounds found inside the item's skin due to excessive contact between certain parts of the material when handled manually.

Embodiment 1

[0024] The processing method of embodiment 1 black fruit Lycium barbarum dried fruit

[0025] a. Prepare edible alcohol with a concentration of 70% v / v and a temperature of -18°C as a cleaning solution;

[0026] b. Take 1 kg of dried wolfberry fruit, put it in 10 times the volume of cleaning solution, and wash it for 0.5 minutes;

[0027] c. After cleaning, let it dry naturally;

[0028] d. Take the above-mentioned naturally dried black wolfberry and put it into a microwave drying box, carry out microwave drying under the conditions that the microwave power is 2000w, the microwave frequency is 2000Hz, and the heating time is 1min.

Abstract

The invention discloses a processing method of black Chinese wolfberry fruits. The processing method of the black Chinese wolfberry fruits comprises the following steps: preparing an alcohol solution of which the concentration is higher than 70% (v/v) and the temperature is 18-25 DEG C, and utilizing the alcohol solution as a washing solution; washing the black Chinese wolfberry fruits in the washing solution, wherein the washing time is 0.5-60 minutes; drying the washed black Chinese wolfberry fruits until no moisture is on surfaces of the black Chinese wolfberry fruits; and heating the processed black Chinese wolfberry fruits by microwave. The processing method of the black Chinese wolfberry fruits disclosed by the invention is highly effective and simple, and is capable of obviously reducing total numbers of colonies of the black Chinese wolfberry fruits, so that the processing method has good sterilizing effects; moreover, the processing method is also capable of greatly reducing anthocyanin losses during the washing processes of the black Chinese wolfberry fruits. The black Chinese wolfberry fruits processed by the processing method have the following advantages: the total numbers of colonies are smaller or equal to 1.5 plus 102 (CFU/g), the anthocyanin loss rates are kept under 5%, and the oxygen radical absorbance capacities are 400-700 micromoles TE/gram; and the prepared black Chinese wolfberry fruits are fresh and bright in color and luster, safe and reliable to human body, green and environment-friendly.
