Embodiment 1
[0021] A green all-natural compound plant-type high-effect vegetable washing salt, including the following components: lake salt 95 wt.%, loofah extract 5 wt.%. Mix evenly according to the proportion of the above ingredients.
[0022] Wherein the preparation method of luffa extract through solution extraction method is as follows:
[0023] (1) A certain quality of fresh loofah was added to 4 times of water and soaked for 5 hours, and the loofah was crushed with a pulverizer, and the pasty loofah was spread and placed in an oven at 40°C for 50 minutes.
[0024] (2) Add a mixture of water and ethanol (water:ethanol volume ratio 5:1) to the pasty loofah and stir for 50 min.
[0025] (3) Use 2 layers of filter cloth to filter the above pasty liquid, and press the filter cloth wrapped with filter residue; filter and squeeze multiple times, finally separate the filtrate and filter residue, and collect the filtrate.
[0026] (4) Add sodium alginate of 0.2% of the filtrate mass to t...
Embodiment 2
[0029] A green all-natural compound plant-type high-effect vegetable washing salt, including the following components: 90 wt.% of lake salt, 6 wt.% of loofah extract, and 4 wt.% of sodium carbonate. Mix evenly according to the proportion of the above ingredients.
[0030] Wherein the preparation method of loofah extract through enzymolysis method is as follows:
[0031] (1) Preliminary treatment of loofah: select high-quality loofah, rinse it with clean water, remove it with a sieve, and then use a pulverizer to crush the loofah, and place it in an oven at 40 °C for 50 minutes.
[0032] (2) Enzyme treatment of loofah: cellulase and pectinase were added to the above-mentioned treated loofah, the amount of enzyme added was 2% of the total mass, and stirred at 35 °C for 20 min.
[0033] (3) Neutralization treatment solution: Add sodium hydroxide with a concentration of 4 mol / L to the above acid treatment solution, stir while adding, frequently test the pH of the treatment soluti...
Embodiment 3
[0036] A green all-natural compound plant-type high-effect vegetable washing salt, including the following components: well mine salt 88 wt.%, loofah extract 8 wt.%, sodium carbonate 4 wt.%. Mix evenly according to the proportion of the above ingredients.
[0037] Wherein the luffa extract is prepared as follows through the supercritical extraction method:
[0038] (1) Clean the loofah and dry it completely so that the moisture content is less than 5%. Use a pulverizer, masher or flour mill to crush and grind the loofah.
[0039] (2) Weigh a certain mass of loofah powder and put it into the extraction tank of the supercritical extraction equipment, add 4 times the volume of 80% ethanol entrainer at the same time, and soak for 10 h at room temperature. During supercritical extraction, the extraction pressure was fixed at 30 MPa, the flow rate of carbon dioxide was kept constant at 12 L / h, the temperature of the separation tank was 75 °C, and the pressure was 6.2 MPa.
