1. Quality Control: How Matcha Powder is Tested
Matcha undergoes rigorous testing to ensure safety and potency:
Pesticide Residues: Analyzed via HPLC (High-Performance Liquid Chromatography) for organic phosphorus/chlorine pesticides
Protein Content: Measured using the Kjeldahl method per GB 5009.5-2016 standards
Particle Size: Laser granulometers verify 60% particles ≤18μm (per GB/T 34778-2017)
2. Grades & Applications
Ceremonial Grade (≥30% amino acids): For traditional tea ceremonies, with vibrant color and umami flavor
Culinary Grade (10-20% caffeine): Ideal for lattes, baking, or smoothies, balancing cost and performance
Industrial Grade (≤10% caffeine): Used in cosmetics or flavored snacks for color retention
3. Key Physical Properties
Color: High-grade matcha is emerald green (due to shaded growth preserving chlorophyll), while low-grade appears yellowish
Solubility: Water-soluble but mixes better with warm (70°C) liquids; oil-soluble for fat-based recipes like ice cream
4. Storage Tips
Airtight & Dark: Use opaque containers to prevent oxidation (light turns powder gray)
Cool/Cold: Store below 25°C or refrigerate; freeze for long-term preservation
5. Addition Amount:
the golden ratio of baking and beverages:
Baked goods: add 3-6g (cake/biscuits) or 5-8g (bread) per 100g flour. Excessive use can easily lead to bitterness
Drinks: It is recommended to mix 2g of matcha powder with 500ml of water. It can be drunk hot or cold, and can be mixed with milk
