Embodiment 1

[0016] Embodiment 1: The production method of this deodorized cabbage red pigment adopts following processing steps:

[0017] 1. Raw material pretreatment: take 1000kg of purple cabbage raw material, wash, trim, and cut into 3mm coriander;

[0018] 2. Extraction: Use citric acid aqueous solution with pH=3.0 as the extraction solution for purple cabbage shredded cabbage. The extraction temperature is 30°C and the ratio of solid to liquid is 1:3. Continuous countercurrent extraction is performed three times, the first extraction is 2 hours, and the second extraction is 2 hours. , three times for 1 hour each; the continuous countercurrent extraction mentioned here is that the new material (purple cabbage shredded) and the new extraction solvent are respectively put into the two ends of the extraction line and move in reverse to achieve efficient extraction;

[0019] 3. Precipitation: Combine the three extracts and let it settle at 2°C for 24 hours; obtain the supernatant;

[002...

Embodiment 2

[0028] Embodiment 2: The production method of this deodorized cabbage red pigment adopts the following processing steps:

[0029] 1. Raw material pretreatment: take 2000kg purple cabbage raw material, after cleaning and trimming, cut it into 5mm shredded cabbage;

[0030] 2. Extraction: Purple cabbage shredded is extracted with tartaric acid aqueous solution with pH = 3.5, the extraction temperature is 40°C, the ratio of solid to liquid is 1:4, continuous countercurrent extraction is performed twice, and the extraction time is: the first time is 2 hours, the second time 2 hours;

[0031] 3. Precipitation: Combine the secondary extracts and let it settle at 4°C for 24 hours; obtain the supernatant;

[0032] 4. Filtration and impurity removal: the supernatant is roughly filtered through a 300-mesh filter bag three-legged centrifuge, and then filtered through a 10 μm and 1 μm plate-and-frame filter to obtain the filtrate;

[0033] 5. Deodorization: The filtrate is subjected to ...

Embodiment 3

[0040] Embodiment 3: the production method of this deodorized cabbage red pigment adopts following processing steps:

[0041] 1. Raw material pretreatment: take 2000kg purple cabbage raw material, after cleaning and trimming, cut it into 2mm shredded cabbage;

[0042] 2. Extraction: Purple cabbage shredded cabbage is extracted with citric acid aqueous solution with pH=2.0, the extraction temperature is 20°C, the ratio of solid to liquid is 1:5, continuous countercurrent extraction is performed twice, and the extraction time is: the first time is 3 hours, the second time over 1 hour;

[0043] 3. Precipitation: combine the secondary extracts, and set aside at 1°C for 12 hours; obtain the supernatant;

[0044] 4. Filtration and impurity removal: the supernatant is roughly filtered through a 300-mesh filter bag three-legged centrifuge, and then filtered through a 10 μm and 1 μm plate-and-frame filter to obtain the filtrate;

[0045] 5. Deodorization: The filtrate is adsorbed wit...

Abstract

The invention discloses a production method of deodorized red cabbage pigment. The production method comprises the steps that fresh purple cabbages are subject to the processes of raw material pretreatment, extraction, precipitation, filtration and impurity-removal, macroporous resin purification, concentration and drying, and then the red cabbage pigment is obtained, wherein an deodorization process is conducted between the filtration and impurity-removal process and the macroporous resin purification process; and the deodorization process comprises the step that odor of filtrate obtained after the filtration and impurity-removal process is adsorbed by using ion exchange resin selected from D001, D301, D301FC or 001 multiplied by 7. The method has the advantages that the ion exchange resin is utilized to deodorize the red cabbage pigment, a treated liquid pigment product is odorless, and a powdery odorless product having high color value can be obtained after the liquid pigment product is spray-dried; according to the production method, no extra solvent is added and other equipment is not used, so that the production method is simple, rapid, economical and practical; and the obtained red cabbage pigment has high color value, is odorless, is soluble in water, produces no precipitate and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of food additive natural pigment refining, in particular to a production method of deodorized cabbage red pigment. Background technique [0002] Cabbage red pigment is a natural food coloring extracted from cruciferous cabbage. The pigment is a mixture of various anthocyanins, bright in color, moderate in tone, contains a variety of nutritional functional components, has high nutritional value, health care and medical functions, not only can be used for coloring candy, beverages, cakes and other foods, but also used as Widely promoted to various fields such as medicine and biochemical products. At present, there are phenomena such as low color price and peculiar smell in the production industry of cabbage red pigment, which seriously affect its sales and use. Cabbage is a cruciferous plant, and the extracted cabbage red pigment has the common characteristics of cruciferous, and has an unpleasant odor, which seriousl...
