Embodiment 1

[0032] The two-color black and red wolfberry slices described in this embodiment are prepared by the following steps: washing fresh wolfberry black fruit and wolfberry red fruit separately, and removing fruit stalks, impurities, and moth-eaten fruits; and then using a juicer to separate Lycium ruthenicum and Lycium ruthenicum are juiced; then the obtained juice is ground with a colloid mill to obtain a juice with a pulp particle size of 1~150μm, and homogenized with a homogenizer; then the homogenized juice is freeze-dried The machine is freeze-dried; and the pre-freezing time is 3 hours, the temperature is -30°C; afterwards, the freezing is carried out, the freezing time is 30 hours, the temperature is -50°C; then the temperature is raised to -20°C, and the crusher is used for crushing And get the lyophilized wolfberry powder with a particle size of 1~150 μm. Afterwards, the obtained Lycium ruthenicum lyophilized powder and Lycium arborescens lyophilized powder are added to a ...

Embodiment 2

[0034] The two-color black and red wolfberry slices described in this embodiment are prepared by the following steps: the dried black wolfberry and the dried red wolfberry are subjected to a dampness treatment, wherein the ratio of the dried black medlar and the dried red medlar to water is 1:2, and the dampness is returned The time is 1~12 hours; then the juice extractor is used to squeeze the wolfberry black fruit and the wolfberry red fruit respectively; then the obtained juice is ground with a colloid mill to obtain a juice with a pulp particle size of 1~150μm, and a homogenizer Perform homogenization; then freeze-dry the homogenized juice with a freeze dryer; and the pre-freezing time is 2 hours at a temperature of -30°C; then it is frozen, the freezing time is 40 hours at a temperature of -40°C ; Then the temperature is raised to 0° C., and crushed with a pulverizer to obtain a freeze-dried wolfberry powder with a particle size of 1 to 150 μm. Afterwards, the obtained Lyc...

Embodiment 3

[0036] The two-color black and red wolfberry slices obtained in Example 2 were sterilized by ultraviolet light with a wavelength of 100nm, and the irradiance was 0.5mWcm. -2 ; Then the wolfberry slices that have been sterilized by ultraviolet rays and the wolfberry slices (single slices) that have not been sterilized are diluted and cultured on the aseptic operating table with a dilution gradient of 1:100, and then used The beef extract peptone medium and lactose bile salt fermentation tube were cultured, and then incubated in a 37°C incubator at a constant temperature for 48 hours and 36 hours; the experimental results showed that the total number of colonies after the untreated sample was cultured was 50,000 to 150,000 / The total number of colonies in the sample after the above treatment is less than 1000 / g.

Abstract

The invention relates to a black red double-color lycium barbarum slice. The black red double-color lycium barbarum slice is prepared from black lycium barbarum and red lycium barbarum serving as raw materials by juicing, homogenizing, freeze-drying, crushing and tabletting; any auxiliary material, except water, is not added in all process steps. According to the black red double-color lycium barbarum slice, the low-temperature crushing process is adopted for crushing the cell walls of both black lycium barbarum and red lycium barbarum, and thus water, oil and effective components in cells can be completely exposed, so that the surfaces of fine particles present a semi-humid state; such structure ensures uniform distribution of nutritional components inside and is also beneficial to increase of good utilization rate; in addition, the low-temperature crushing and low-temperature tabletting processes are combined, so that the lycium barbarum slice with proper hardness can be obtained under the condition that any adhesive such as starch is not added; therefore, any auxiliary material is not added in the lycium barbarum slice, all the flavors of lycium barbarum are remained, and the safety and reliability of foods are improved.

Description

technical field [0001] The invention relates to the technical field of food preparation, more specifically, the invention relates to a double-color black-red-fruit wolfberry tablet and a preparation method thereof. Background technique [0002] Lycium barbarum, also known as western wolfberry, white thorn, mountain wolfberry, etc., is the mature fruit of Lycium barbarum, a plant of the Solanaceae family. Lycium barbarum plays an important role in traditional medicine in my country, and its medicinal value has been highly praised by doctors of all ages.
