Establish the necessity of chromatographic determination of preservatives and sweeteners in wine and fruit wine

Wine and fruit wine belong to fermented wine. From the supervision and spot check of the past years, the quality level has been continuously improved, which is gratifying. But the quality problems that exist are also not to be ignored. In order to improve the competitiveness of China's wine and fruit wine in the international market, we should establish and improve the detection technology and safety and health assurance system for preservatives and sweeteners in wine and fruit wine as soon as possible.

Benzoic acid, sorbic acid, and sodium saccharin are mainly determined by gas chromatography and high performance liquid chromatography. Both methods are national standard methods.

Cyclamate mainly by gas chromatography, a higher vaporization temperature of the sample is measured by gas chromatography method for purification process and demanding real samples, reported in recent years, measured by HPLC cyclamate gradually increased, but Because the UV detection signal of cyclamate is weak, the HPLC detector is used to enhance the intensity of the UV signal. This method adds a lot of steps to the pretreatment of the sample, which is difficult to meet the actual work. The analysis of the sample is required.

Aspartame does not have a national standard test method. Most of the benzoic acid, sorbic acid, sodium saccharin, cyclamate, and aspartame are single-labeled analytical methods. That is to say, one sample pretreatment and chromatographic analysis can only determine one type. The composition, which is extremely unsuitable for the supervised sampling of a large number of samples, is necessary to establish a method for the determination of preservatives and sweeteners in wine and fruit wine.

What is photobiomodulation?

Photobiomodulation (PBM) is a non-invasive treatment method that uses light of a specific wavelength to affect the function of biological cells and tissues.

Its core principle is that when light of a specific wavelength is absorbed by the chromophore in the cell (such as cytochrome C oxidase in mitochondria), it will trigger a series of changes in biochemical reactions and signal pathways in the cell. These changes can include increasing cellular energy production (such as increasing mitochondrial ATP synthesis), regulating the redox state of cells, promoting cell proliferation and differentiation, inhibiting inflammatory responses, stimulating angiogenesis, and enhancing cell survival.

Photobiomodulation has applications in many fields, such as promoting wound healing, relieving pain, treating neurodegenerative diseases, and improving skin conditions. Light of different wavelengths and energies may produce different effects, and the specific application and effect depend on the parameters of the light and the target tissue and disease condition of the treatment.

How does 810nm have a beneficial effect on the brain?

The mechanism of 810nm near-infrared light on brain health mainly includes the following aspects:

First, photobiomodulation. 810nm near-infrared light can be absorbed by mitochondrial pigments in cells, thereby activating a series of intracellular signaling pathways. This can enhance mitochondrial respiration, increase cell energy production, and provide support for the normal function and metabolism of nerve cells.

Second, regulate neuroinflammatory response. It can inhibit the release of inflammatory factors, reduce brain inflammation, create a relatively stable and favorable microenvironment for nerve cells, and help protect nerve cells from inflammatory damage.

Third, promote angiogenesis and improve cerebral blood flow. Stimulate endothelial cell proliferation and migration, induce the formation of new blood vessels, thereby increasing blood supply to the brain. At the same time, by dilating existing blood vessels, further improve cerebral blood flow, and provide brain cells with sufficient oxygen and nutrients.

Fourth, regulate neurotransmitter balance. Affect the synthesis, release and metabolism of neurotransmitters, such as dopamine and serotonin, thereby improving the brain's neurotransmission function and having a positive impact on emotions, cognition, etc.

Fifth, stimulate neuroplasticity. Stimulate the proliferation and differentiation of neural stem cells, promote the formation and remodeling of synapses, help repair and rebuild damaged neural circuits, and improve the brain's ability to adapt and recover.

In short, 810nm near-infrared light plays a positive role in maintaining and improving brain health through a variety of comprehensive effects.

What diseases can 810nm helmets be used for? Here are some of the benefits of PBM light therapy for brain disorders:

1. Neuroprotection: PBM light therapy has been found to have neuroprotective effects, meaning it can protect the brain cells from damage and degeneration. It can help reduce inflammation and oxidative stress in the brain, which are common factors in many brain disorders.

2. Improved cognitive function: PBM light therapy has been shown to enhance cognitive function, including memory, attention, and problem-solving skills. It can stimulate the production of brain-derived neurotrophic factor (BDNF), a protein that promotes the growth and survival of brain cells.

3. Reduced symptoms of depression and anxiety: PBM light therapy has been found to have antidepressant and anxiolytic effects. It can increase the production of serotonin, a neurotransmitter that regulates mood, and reduce the activity of the amygdala, a brain region involved in fear and anxiety.

4. Enhanced neuroplasticity: PBM light therapy can promote neuroplasticity, which is the brain's ability to reorganize and form new connections. This can be beneficial for individuals with brain disorders as it can help improve their ability to learn, adapt, and recover from injuries.

5. Accelerated healing after brain injuries: PBM light therapy has been shown to accelerate the healing process after brain injuries, such as traumatic brain injury or stroke. It can improve blood flow to the injured area, reduce inflammation, and stimulate the repair and regeneration of damaged brain cells.
