2. Chlorophyll and nutrition in fresh herbal tea
Herbal tea is different from tea made from tea leaves (tea leaves) in that it is not fermented and the nutrients are extracted with boiling water in the same way as regular tea. However, chlorophyll and nutrients need to be protected from the harmful effects of fermentation, acidic pH and high temperatures, with special attention given that plant extracts are mostly naturally pH sensitive. acid [1], therefore, after extraction, the substances will be decomposed due to the acidic pH of the extract itself.
Sensitivity to pH, temperature, fermentation… are challenges with current herbal tea production technologies such as cool drying (fan and not direct sunlight) or cold drying to protect chlorophyll and nutrition. However, because the way to drink tea is to steep the tea with boiling water at 100 oC, substances with inherently low levels of antioxidant and anti-inflammatory activity will be decomposed, as well as the water pH from neutral to slightly acidic also contributes. The part that causes the health-promoting substances of herbal tea to be completely lost [2, 3]
II. Fixes chlorophyll and protects the nutrients of fresh herbal tea
1. Operating principles of technology
The solution offered by Sac Moc Tinh company is to “alkalize” fresh herbal leaf materials. We use chlorophyll color as a color indicator for the stability of chlorophyll and nutrients at alkaline pH and high temperatures. Because chlorophyll is a green substance and easily changes its green color according to pH as well as turns blue-black when exposed to high temperatures (illustrated in Figures 1& 2) [4]. From there, we can know that chlorophyll and nutrients are preserved at alkaline pH and can withstand high temperatures, from ensuring health support features, such as bamboo leaves helping to nourish the kidneys. , laxative and increase resistance according to medical literature [5, 6].
2. Outstanding advantages of technology:
– Maintains the freshness and flavor of tea
– Maintains nutritional content
– Extend storage time
III. Cooperation opportunities
– We calculate technology rental costs as follows:
• Technology rental fee for 5 years (collected once): 100,000,000 VND (one hundred million VND)
• Chemical treatment calculation (collected for each production batch): 200,000 VND (two hundred thousand VND) for 100 kg of fresh ingredients (obtains about 10 kg of dry ingredients after freeze-drying)
– If your company wishes to cooperate, please contact Teacher Thanh directly via phone number 0966.88.99.36 or email:
