COA Of Broccoli seed extract

Why choose KINTAI Broccoli seed extract?
1. broccoli seed extract Safety, stability and efficacy
Our broccoli seed water extract is produced strictly in accordance with the new food raw material process standards, and the main ingredient glucoraphanin content reaches 13%-20%, ensuring the activity and stability of the product. At the same time, we also meet the light stability requirements and use light-proof packaging such as aluminum foil bags to prevent the active ingredients from degrading under light conditions to ensure the long-term effectiveness of the product.
2. Planting technology advantages
01: High content of glucoraphanin comes from high-quality seeds:

Because among all cruciferous plants, broccoli has the highest content, which is far higher than the content in radish. The content of glucoraphanin in broccoli seeds is the highest, followed by broccoli sprouts, and then fresh broccoli and refrigerated broccoli. As broccoli grows and develops, the content of glucoraphanin is also rapidly declining, so the highest content is still in the seeds.

We use high-quality seed resources from more than 30 varieties around the world, and through more than a dozen generations of cultivation and screening, we have obtained broccoli seed varieties that perform well in content stability and yield. These seeds contain glucoraphanin content far exceeding that of ordinary varieties, ensuring the high efficiency of the extract from the source.
In addition, we have more than 10 years of broccoli planting experience in Sichuan, and have established in-depth cooperative relationships with local growers. Through strict planting guidance and supervision, we have achieved a high degree of control over the quality of raw materials, ensuring that the content of glucoraphanin in the finished product is stable between 13% and 20%, which fully meets the production standards of new food raw materials.
Broccoli Seed Extract Extraction process improvement: technical barriers of water extraction process
For ten years, we have invested a lot of energy in the process research and development of glucoraphanin extraction. Its unique water extraction process retains the precious active ingredients in broccoli seeds to the maximum extent. Compared with other plant extracts, the extraction of glucoraphanin has extremely high process requirements. The control of temperature, light and enzymes during the extraction process directly affects the purity and efficacy of the finished product. We have formed patented technology in process control to ensure product stability while meeting customers' needs for high-purity and high-quality raw materials.
At the same time, our advantages not only enable it to provide broccoli seed water extracts that meet the standards of new food raw materials, but also meet the different needs of customers, provide glucoraphanin extracts of different specifications from 1% to 20%, and can provide glucoraphanin products with a purity of up to 98% to meet the needs of different markets and applications.
3. Full industry chain advantages in quality and supply chain
We implement full industry chain control in the production process of broccoli seed water extract, covering multiple links such as seed cultivation, raw material planting, extraction and processing. This full industry chain model enables us to control every link throughout the process to ensure the stability and traceability of the finished product quality. This advantage is particularly suitable for customers such as health products and medicines who have strict requirements on raw material quality, and also makes our products more competitive in the market.
what is broccoli seed extract good for ?
broccoli seed extract benefits For Strong antioxidant and anti-inflammatory effects
Glucoraphanin and sulforaphane have excellent antioxidant and anti-inflammatory effects, which can remove reactive oxygen free radicals in the body and slow down oxidative damage to cells. Glucoraphanin can also further strengthen the body's antioxidant and anti-inflammatory defenses by activating the Nrf2 gene. Nrf2 is the core transcription factor that controls antioxidant and detoxification genes.

Normally, it binds to the Keap1 protein and remains in a static state, but under the action of sulforaphane, the conformation of Keap1 changes, allowing Nrf2 to enter the cell nucleus and activate a large number of antioxidant enzymes and detoxification enzymes. This not only helps to remove toxins from the body, but also inhibits the expression of inflammatory factors and reduces the damage of inflammation to the body.
broccoli seed extract benefits as The liver's detoxification factory: Phase I and Phase II detoxification mechanisms
The liver is a key organ for human detoxification, responsible for the decomposition and removal of endogenous and exogenous toxins. The liver's detoxification mechanism is divided into two stages: Phase I and Phase II:

Phase I detoxification: Preliminary metabolism through the cytochrome P450 enzyme system (such as CYP3A4, CYP1A2, etc.), usually produces potentially toxic intermediates.
Phase II detoxification: Under the action of quinone reductase (QR) and glutathione transferase (GST), the products of Phase I are further modified to make them easier to excrete from the body. This step is particularly important in eliminating oxidative stress products such as reactive oxygen and protecting cell mitochondria and DNA.
Glucoraphanin plays a particularly significant role in phase II detoxification. It can activate phase II detoxification enzymes (QR and GST), improve the efficiency of liver toxin removal, and inhibit the activity of cytochrome P450, thereby reducing the harmful intermediates that may be generated in phase I detoxification.
