Witness Borong’s manufacturing capabilities based on simple facts.
Borong follows well-controlled production processes designed to deliver natural extracts with consistent quality and preserved nutritional value.
At Borong, excellence begins at the source. Our marigolds come from our self-owned plantations in Yunnan and Gansu. By overseeing the entire process—including seed screening, nursing, rigorous pest control, and climate-resilience strategies—we guarantee superior raw materials with high lutein potency and a stable supply.
Our fermented marigolds are processed through automated pressing, drying, and pelletizing stages. By strictly following standardized procedures, we maximize the preservation of lutein content and ensure a consistent, high-quality substrate for final extraction.
The advanced extraction workshop gently and efficiently isolates the bioactive components through the latest subcritical technology. With the help of a closed-loop, low-temperature system, we can maximize the yield while preserving the natural integrity of the ingredients.
Saponification hydrolyzes lutein esters into free lutein using an alkaline solution. The mixture is then neutralized, washed, and purified to obtain the lutein extract.
We operate Class 100,000 cleanrooms, enabling the production of powders, microencapsulated powders, beadlets, and oil suspensions for dietary supplement and nutraceutical ingredients. Controlled environments and standardized processes ensure consistent quality, safety, and suitability for global applications.
We believe that industrial growth should be aligned with environmental responsibility.
With an investment of USD 2.9 million in dedicated wastewater treatment systems, all production wastewater is fully treated and meets national discharge standards, ensuring environmental protection and long-term, sustainable manufacturing.
