Detailed Description
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example one
A method for processing ginger resources completely, which comprises the following steps with reference to figure 1:
step (1): pulverizing rhizoma Zingiberis recens, and squeezing to obtain rhizoma Zingiberis recens cloudy juice and rhizoma Zingiberis recens coarse residue.
Step (2): centrifuging the ginger coarse residue to obtain ginger fiber and ginger protein liquid; and (4) filtering the ginger cloudy juice to obtain ginger clear juice.
And (3): distilling the ginger juice to extract oil to obtain ginger oil and distillation residues.
It is noted that ginger oil has a strong aromatic odor, is mainly applied to flavoring and seasoning of food and beverage, and is also an essence raw material and a medicinal raw material with a high price which are taken first in markets at home and abroad at present. Can be used as ideal essence for cosmetics, especially perfume for men, and natural food essence. Ginger oil is a novel and valuable material for modern food, medicine and light chemical industries, and is popular in domestic and foreign markets.
And (4): and filtering the distillation residue by using a membrane to obtain a trapped fluid and a permeate.
And (5): drying trapped fluid and spraying powder to obtain the dietary fiber.
It should be noted that ginger contains a large amount of cellulose and starch, and the comprehensive utilization degree of ginger as a residue of deep processing is not so deep that intensive studies have not been made. In recent years, soluble as well as insoluble dietary fibers have begun to enter the market as health foods with efficacy of clearing intestinal toxins, losing weight, reducing fat, and the like. The research on the ginger dietary fiber has certain value for promoting the efficient utilization of ginger.
And (6): adsorbing the permeate with resin, eluting the resin adsorbate with hot water, cooling the hot water eluate, concentrating with film, and drying to obtain gingerol; eluting the resin adsorbate eluted with hot water with salt solution, desalting the eluate film of the salt solution, concentrating the film, and drying to obtain curcumin.
It should be noted that gingerol is a generic term for gingerol, zingiber officinale and other pungent substances related to ginger. The gingerol has strong effect of resisting lipofuscin. Curcumin is orange yellow crystal powder, slightly bitter in taste and insoluble in water, and is mainly used for coloring products such as sausage products, cans, sauced and marinated products and the like in food production. Curcumin has the effects of reducing blood fat, resisting tumors, resisting inflammation, benefiting gallbladder, resisting oxidation and the like, and in addition, scientists find that curcumin is helpful for treating drug-resistant tuberculosis.
And (7): and drying the ginger protein liquid at low temperature to obtain the ginger protease.
It should be noted that, the research on ginger protease provides a theoretical basis for the application of ginger protease in the food field, changes the current situation that the plant protease resources in China mainly depend on a few tropical fruit resources such as pawpaw and pineapple for a long time, and is beneficial to the full utilization of ginger resources. The protease has the function of curdling, the activity and the yield of the enzyme are high, the industrial production value is high, and the ginger protease has the functions of invigorating stomach and benefiting spleen. The ginger protease can also be used as a meat tenderizer, and plays a great role in the aspects of food nutrition flavor, product processing adaptability, product stability and the like.
And (8): carrying out anaerobic fermentation on ginger fibers to obtain aged bacterial sludge and methane; purifying the biogas to obtain biogas; and (4) drying the aged bacterial sludge by hot air to obtain the special organic fertilizer.
It should be noted that the ginger residues produced in the above steps and the rotten ginger as waste can be fermented together with the waste water in the production process during anaerobic fermentation, so that the method is environment-friendly and energy-saving, can greatly improve the added value of the processed ginger product series, improves the utilization rate of ginger resources, and achieves the green ecological processing goal of no three-waste pollution and zero discharge.
