Study Notes
Herbal Drinks
- Herbal beverages are rich in bioactive compounds like carotenoids, phenolic acids, flavonoids, coumarins, alkaloids, polyacetylenes, saponins, and terpenoids.
- Used traditionally across cultures, especially in regions where alternative medicine is prevalent.
- Popular herbal teas include Aegle marmelos (Bael), Centella asiatica (Gotukola), Cassia auriculata (Ranawara), Aerva lanata (Polpala), and Hemidesmus indicus (Iramusu).
Fruit Juice
- Made from a variety of fruits such as oranges, apples, grapes, cranberries, pineapples, and mangoes.
- Juice is extracted through crushing or blending techniques.
Coconut Water
- A refreshing and natural hydrating drink.
- High in potassium and other electrolytes, making it healthy and energizing.
Plant Milk
- Offers alternatives for those with milk allergies or lactose intolerance, and is preferred for environmental concerns.
- Made from rice, soy, almonds, coconut, oats, potatoes, or hemp.
- Production involves water extraction from legumes, nuts, or cereals, and can be fortified with vitamins, minerals, and proteins.
Alcoholic Beverages
- Classified into two types: fermented and distilled.
- Fermented beverages are made from the natural fermentation of sugars found in fruits or starches, while distilled beverages undergo distillation to increase alcohol content.
- Fermentation processes trace back to 5000-6000 BC, with distillation being a more recent development.
Fermented Beverages
- Includes wine, beer, toddy, and sake, all made from fermenting sugars.
Wine
- The oldest known alcoholic beverage with evidence of production over 5500 years ago.
- Created from the fermentation of sugars predominantly found in grapes.
Tea
- Second most popular beverage globally, derived from the dried leaves of Camellia sinensis.
- Originated in China, with consumption spread across Asian countries.
- Grown in Sri Lanka across three elevation levels: low, mid, and high grown.
- Harvesting is typically done by hand focusing on terminal buds and young leaves.
Types of Tea
- Green tea is minimally processed with no oxidation.
- Oolong tea is semi-oxidized.
- Black tea undergoes full oxidation, creating distinct flavors and qualities.
Tea Production
- Green tea production methods include steaming (Japanese) and pan-firing (Chinese).
- Black tea production involves several steps: withering, rolling to start oxidation, fermentation, drying, and sorting.
Coffee
- Derived from Coffea canephora (Robusta) with origins in the highlands of Ethiopia.
- The “coffee rush” of the mid-1980s led to increased cultivation in Sri Lanka, though many plantations were later devastated by a fungal disease called “coffee rust.”
Coffee Processing
- Two primary methods: wet processing (superior flavor) includes pulping, fermentation, washing, and drying; dry processing skips fermentation, drying coffee directly.
- Roasting coffee beans develops aroma, flavor, color, and taste through chemical changes in oils and sugars.
Coffee Products
- Includes “Kopi luwak,” the most expensive coffee known for its unique fermentation process through digestion by civets.
