Mustard oil is loved by people for its unique irritating odor and spicy flavor, and it can be used for refreshing and improving appetite.
First, the main equipment constant temperature water bath, grinding machine, distiller, oil-water separator, soaking containers, deployment of containers, filling machines, labeling machine.
Second, the formula of vegetable oil 99%, mustard essential oil 0.1% -1%.
Third, the process mustard seeds → soak → crush → acid → hydrolysis → distillation → separation → mustard oil → deployment → filling → labeling → finished product.
Fourth, the operating point
1. Raw material mustard seeds with full grain, large grains and dark yellow color are used as raw materials.
2, soaking Weed seeds must be weighed, add 6 times -8 times warm water around 37 °C, soak for 25 hours - 35 hours.
3. Pulverize the soaked mustard seeds and pulverize them in an attrition mill. The finer they are, the better. The mustard paste is obtained.
4, adjust the acid with white vinegar adjustment mustard paste PH value of about 6.
5, hydrolysis will be adjusted to a good pH value of the mustard paste into the hydrolysis vessel placed in a constant temperature water bath, at about 80 °C heat hydrolysis for 2 hours -2.5 hours.
6. Distillation The hydrolyzed mustard paste is placed in a distillation apparatus and steam distillation is used to distill the spicy material out.
7. The distillate after separation and distillation is an oil-water mixture, which is separated by an oil-water separator to obtain mustard essential oil.
8. Mix and mix the mustard oil and vegetable oil according to the formula and mix well, that is, mustard oil.
9. Filling mustard oil is filled in pre-washed, disinfected, and dried glass bottles, labelled, sealed, and is finished product.
Fifth, quality standards mustard oil should be light yellow oily liquid, with a strong spicy pungent taste and tear.
Six, matters needing attention
1, the hydrolysis should be carried out in a closed container to avoid volatile volatile substances, affect product yield and quality. When steaming, try to make all the spicy substances steam out and reduce the loss.
2, mustard oil should be placed in a cool dark place, avoid contact with water, or prone to chemical reactions, affect product quality.
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.
♣.Structural composition: Combination of cotton swab and transport medium (VTM).
♣. Product requirements:
The product should be airtight, avoid high temperature, avoid direct sunlight storage. It should be used in a clean, hygienic, pollution-free, and temperature-friendly environment.
♣, Storage conditions and validity period:
â‘ , the product should be stored in a clean, dry and ventilated environment,
②, the temperature is 5℃-35℃;
â‘¢, relative humidity <85%RH;
â‘£, product shelf life: 12 months.
♣. How to use
â‘ Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
Mustard oil extraction
The seeds of mustard can be extracted with mustard oil, which has a beneficial effect on coldness, swelling, and swelling. It can be used as a seasoning for sauerkraut, mayonnaise, salad, and curry powder.
