What is Concentrated Green Tea?
Concentrated green tea refers to green tea where the natural compounds have been concentrated into a more potent liquid form. This process removes excess water while retaining beneficial compounds like antioxidants, amino acids, vitamins, and minerals. The result is a powerful health drink that provides stronger effects compared to regular strength green tea.
How is Concentrated Green Tea Made?
There are a few common methods used to produce concentrated green tea:
- Freeze-drying or lyophilisation: This removes water via freezing and drying the tea under vacuum pressure.
- Spray drying: Tea compounds are sprayed in a fine mist to remove moisture quickly.
- Vacuum concentration: Water is evaporated under low pressure at moderate temperatures.
These processes allow the antioxidants, amino acids, enzymes, and micronutrients in green tea to be delivered in smaller volumes for amplified health effects. The finished concentrated tea can be diluted or used as is.
Benefits of Concentrated Green Tea
Drinking concentrated green tea provides stronger health benefits compared to regular strength tea. Benefits include:
- Higher antioxidant levels to fight free radicals
- Increased fat burning and weight loss effects
- More support for heart, brain, and metabolic health
- Higher concentration of compounds that fight diseases
- Stronger anti-aging effects on cells
Essentially, concentrated green tea is like getting 2-3 times the health benefits of regular green tea in each serving. This makes it easier to get therapeutic effects without having to drink large volumes of tea.
Active Compounds in Concentrated Green Tea
Concentrated green tea contains a number of beneficial bioactive compounds at high levels. These include:
Catechins
Catechins like EGCG (epigallocatechin gallate) are antioxidant compounds linked to anti-aging, cancer prevention, weight loss, heart health, and reduced risk of diabetes. Concentrated green tea can contain 2-5 times the EGCG content by weight compared to brewed teas.
Theanine
Theanine is an amino acid that has anti-anxiety and calming neurological effects. Concentrating green tea allows more theanine to be delivered per serving, amplifying these relaxing qualities.
Vitamin C
Green tea contains vitamin C, an essential antioxidant that boosts immunity and helps produce collagen for healthy skin and joints. Concentrated varieties provide higher vitamin C levels in a convenient format.
Fluoride
Green tea also contains fluoride which supports dental health by making teeth more resistant to decay. Concentrating tea leaves into smaller volumes effectively concentrates this mineral as well.
Other Micronutrients
In addition to the above, concentrated green tea contains a spectrum of mineral micronutrients like manganese, chromium, zinc, magnesium, and more. It also contains various antioxidant polyphenols and plant compounds that boost health.
Comparison of Concentrated vs Regular Green Tea
So how exactly does concentrated green tea compare to regular leaf or bagged green teas?
Basic Properties
While regular brewed teas contain ~0.3-0.5g of beneficial green tea compounds per cup, concentrated versions can contain upwards of 1-3g per serving. Concentrated green tea also has 90-98% less water content by weight.
Antioxidant Strength
In terms of antioxidant power, concentrated green tea has an ORAC value exceeding 15,000mol TE/g compared to around 1,500mol TE/g in brewed green tea. This 10x higher ORAC score demonstrates the amplified free radical fighting potential.
Nutrient Levels
Important catechins like EGCG are found in amounts of 200-600mg per serving in concentrated green tea. Regular brewed tea contains just 20-50mg. So concentrated versions provide a major boost in beneficial nutrients.
Economical Use
Since less actual tea is required per serving when using concentrated formats, this allows the leaves to be stretched further. You need 3-10 times less tea by weight to achieve equal or greater effects.
Taste Profile
Concentrating green tea to higher strength levels can intensify its natural grassy, vegetal taste. Some find this taste overpowering. Diluting down to taste is recommended when drinking as a beverage.
Best Uses for Concentrated Green Tea
Here are some of the top ways to utilize concentrated green tea:
Diluting as a Beverage
The easiest use is diluting 1 part concentrated tea to 2-4 parts water. This reduces the intensity while allowing you to get a single serving of compounds that would normally require drinking multiple cups.
Adding to Smoothies & Shakes
Add concentrated green tea by the teaspoon or tablespoons to smoothies and shakes. This integrates the health benefits into your blended drinks.
Using in Coffee
Add concentrated green tea to coffee beverages like lattes to experience the unique flavor and health kick. It pairs well with espresso drinks.
Baking & Cooking
Use concentrated green tea to enhance the nutrient quality of foods like muffins, soups grains or entree dishes. It infuses recipes with antioxidants.
DIY Skincare Formulas
Harness benefits for skin and hair by adding concentrated green tea to your own masks, scrubs and care formulas.
Potential Side Effects
Concentrated green tea is very safe for most people. But stronger potency means higher caffeine levels per serving. Side effects can include:
- Jitters, headaches, irritability from excess caffeine
- Upset stomach or nausea when consumed in excess
- Difficulty sleeping if consumed late in the day
- Interactions with medications for those sensitive to caffeine
To avoid issues, limit intake to the equivalent of 2-3 regular cups of green tea spaced throughout the day. Drink alongside food and discontinue use if any severe reactions occur.
Finding the Best Concentrated Green Tea
Look for reputable brands that specify production methods, concentrations strengths, and levels of key compounds like EGCG. Quality is essential - poorly made versions may contain solvent residues. Organic, non-GMO concentrates are ideal.
Packaging should protect light exposure and seal out oxygen to prevent nutrient degradation before opening. Ask about testing for purity and contaminants.
A good concentrated green tea is made via freeze-drying or spray drying freshly picked tea leaves. This captures nutrients at their freshest. Prices range widely from economy to premium brands - pay more for organic quality.
With so many choices available, be sure to read the detailed label when comparing concentrated green tea products.
FAQs
How is concentrated green tea different from regular green tea?
Concentrated green tea goes through additional processing to remove water and concentrate the actual tea compounds like antioxidants into a more potent liquid extract. This amplifies the levels of beneficial catechins, amino acids, vitamins, and minerals versus regular brewed green tea.
What are the main health benefits of concentrated green tea?
The main benefits of concentrated green tea extracts are higher antioxidant capacity for anti-aging effects, increased fat burning and weight loss, more support for heart and brain health, better defense against diseases like cancer, and stronger anti-inflammatory activity in the body.
What is the best way to drink concentrated green tea?
Concentrated green tea has an intense flavor profile, so the best method is diluting with water before drinking. Use 1 part concentrate to 2-4 parts water. You can also incorporate small amounts into smoothies, coffee drinks, baked goods, or cooking to integrate the health benefits.
Are there any side effects to concentrated green tea?
When consumed in excess, concentrated green tea side effects can include jitters, headaches, nausea, and irritability from the higher caffeine amounts. Start with small doses and avoid late day use if caffeine affects your sleep. Check medication contraindications if you're sensitive.
