Of course, there is also a small amount of thorn pear powder on the market, but the clarity is not good. In addition, because thorn pear powder is easy to absorb moisture, a large amount of auxiliary materials will be added, resulting in a lower taste of the finished product and a lower VC content.
[0003] Chinese patent CN105394646A "A Production Process of Water-Soluble Rosa Roxburghii Powder" discloses a production process of water-soluble Rosa roxburghii powder obtained by ultrasonic extraction. The pretreatment of this method is relatively complicated, and the pretreatment temperature needs to be at 5°C. In addition, Not only will metaphosphoric acid be added, but also a large amount of ethanol is required, which is difficult to be used in industrialized production, and the cost is relatively high; The clarification of the thorn pear powder obtained by the process is better, but after adding gelatin, it needs to stand still for 8-12 hours under the environment of 5-15 ℃, and the processing time is too long; Chinese patent CN107212227A "green and efficient processing method of thorn pear powder" discloses a A thorn pear powder process obtained by enzymatic hydrolysis. The pretreatment of this processing method is cumbersome, and a variety of biological enzyme preparations are added in the processing process, which requires high temperature to inactivate the enzyme, resulting in the degradation of VC. In addition, the thorn pear powder obtained by this method has no After centrifugation or membrane treatment, the clarity is relatively poor; Chinese patent CN101167553A "a processing method of roxburghii powder" discloses the process of obtaining roxburghii powder, and the operation is relatively simple. Only simple filtration and deployment of rox

Embodiment 1

[0078] The preparation method of roxburghii powder rich in vitamin C, its steps are as follows:

[0079] (1) Squeeze fresh prickly pear juice to get prickly pear juice;

[0080] (2) Transfer the thorn pear juice to a fermenter, add 0.3% activated Saccharomyces cerevisiae, set the temperature at 25-40°C, stir and ferment for 4 hours to obtain fermented thorn pear juice;

[0081] (3) The fermentation broth is filtered with a 250-mesh filter cloth, and the filtrate is filtered with a ceramic membrane with a built-in 80nm filter element, and the filtrate is collected for later use;

[0082] (4) Concentrate the filtered prickly pear juice in a vacuum with a vacuum degree of -0.04MPa and a temperature of 45-75°C, and concentrate until the solid content is 20-40% to obtain an extract;

[0083] (5) Take the above-mentioned extract, add 25% modified starch, mix evenly, and dry with a spray dryer. The air inlet temperature of the dryer is 160-205°C, and the air outlet temperature is 70...

Embodiment 2

[0085] The preparation method of the Rosa roxburghii powder rich in vitamin C and SOD comprises the steps:

[0086] (1) Pre-treatment of fresh Rosa roxburghii to obtain Rosa roxburghii concentrated juice;

[0087] (2) Add 8% purified water to the prickly pear juice obtained in step (1), and use Saccharomyces cerevisiae to ferment and process the prickly pear juice. The fermentation time of the Saccharomyces cerevisiae is 6 hours; the temperature of the fermentation process is set to 30°C in the first 3 hours of fermentation, and set to 36°C in the last 3 hours of the fermentation process;

[0088] (3) Filtration treatment, the Saccharomyces cerevisiae fermentation product is first filtered with a filter cloth, and then filtered with a nano filter element ceramic membrane, the filter cloth filter mesh is 300 mesh, and the nano filter element ceramic membrane is filtered with a 100 nanometer filter element;

[0089] (4) Vacuum concentration, the vacuum degree of the vacuum conc...

Embodiment 3

[0092] The preparation method of the Rosa roxburghii powder rich in vitamin C and SOD comprises the steps:

[0093] (1) Prepare materials to obtain thorn pear juice;

[0094] (2) Add 3% purified water to the thorn pear juice obtained in step (1), and use Saccharomyces cerevisiae to ferment and process the thorn pear juice. The fermentation time of the Saccharomyces cerevisiae is 8 hours; in the first 4 hours of the fermentation process, the temperature is set to a fixed temperature value between 25-35°C, and the temperature is set to a fixed temperature value between 35-40°C in the last 4 hours of the fermentation process value;

[0095] (3) Filtration treatment, the Saccharomyces cerevisiae fermentation product is first filtered with a filter cloth, and then filtered with a nano filter element ceramic membrane, the filter cloth filter mesh is 300 mesh, and the nano filter element ceramic membrane is filtered with a 100 nanometer filter element;

[0096] (4) Vacuum concentra...

Abstract

The invention discloses rosa roxburghii tratt powder rich in vitamin C and a preparation method thereof. The preparation method comprises the following steps: (1) pre-treating rosa roxburghii tratt toobtain rosa roxburghii tratt juice or concentrated juice; (2) fermenting the rosa roxburghii tratt juice by using saccharomyces cerevisiae; (3) sequentially filtering by using filter cloth and a nanofilter element ceramic membrane; (4) performing vacuum concentration treatment; and (5) drying. According to the preparation method disclosed by the invention, the saccharomyces cerevisiae is added in the preparation process of the rosa roxburghii tratt powder, and carbohydrates in the feed liquid are effectively reduced through the fermentation effect of the saccharomyces cerevisiae, so that theproportion of the vitamin C in the material is increased, and the content of the vitamin C in the rosa roxburghii tratt powder disclosed by the invention reaches 17% or above. According to the preparation method disclosed by the invention, SOD is effectively enriched, and the content can reach 10-15,000U/g; the yeast and other impurities are filtered by the ceramic membrane, high-temperature treatment is avoided, and degradation of VC is reduced; and the rosa roxburghii tratt powder prepared by the preparation method disclosed by the invention is good in fluidity, effectively inhibits the caking problem, and can be applied to industrial production.

Description

technical field [0001] The invention relates to the technical field of formulation improvement and processing, in particular to cili powder effectively enriched in vitamin C and a preparation method thereof. Background technique [0002] Rosa roxburghii, also known as Wenxianguo and Sending Spring Return, is a perennial deciduous shrub of the Rosaceae Rosa family, widely distributed in warm and subtropical regions. Rosa roxburghii is rich in vitamin C, superoxide dismutase (SOD), Rosa roxburghii flavonoids and other nutrients. Development prospects. Among them, VC, as one of the important indicators to evaluate the quality of Rosa roxburghii, plays a role in scavenging free radicals, anti-oxidation, delaying aging, promoting wound healing, etc., and is also the most needed vitamin for the human body.
