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. Put the above-mentioned natural dried wolfberry black fruit into a microwave drying box, and carry out microwave drying under the conditions that the microwave power is 2000w, the microwave frequency is 2000MHz, and the heating time is 1min. After drying, instant black fruit wolfberry is obtained.

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.
Description
technical field [0001] The invention relates to a processing method for fresh or dried fruit of Lycium ruthenicum, and belongs to the fields of medicine, health care and food. Background technique [0002] Food, especially edible fruits are eaten directly without cooking, which determines that their cleaning is very important. If it is not cleaned properly, it will be harmful to health. Because the fruits on the market currently have more or less pollutants, if they are eaten without careful cleaning, the dust, bacteria, pesticides, etc. remaining on the fruits will be brought into the body, especially if they are eaten frequently, it will seriously endanger human health . [0003] According to the residues of different pollutants and the characteristics of the fruit itself, it is necessary to choose a suitable cleaning solution. Commonly used cleaning solutions are neutral, weakly alkaline and weakly acidic. For example, flour water can be used to absorb impurities for c...
