Hydroponics and Health Benefits of Coriander
Coriander has many applications in culinary preparations because of its flavor, aroma, and taste. Alongside its use as a culinary ingredient, it also has many beneficial health properties. Coriander may not spice up food, but their addition does add a refreshing flavor to dishes and whole foods.
Here’s a brief description of the coriander’s major features:
Hydroponics of Coriander
Hydroponic System
The nutrient film technique is the commonly used hydroponic system for coriander’s cultivation. Alternatively, the deep flow technique or deep water culture are also used.
Temperature
Coriander requires a temperature in the range of 40 °F to 75 °F to grow and 70 °F for optimum growth.
Nutrients
Application of a (25:12.5:12.5 kg/ha) NPK fertilizer has a positive stimulatory effect on three things: biomass, seed, and essential oil yield. (Effect of vermicompost and chemical fertilizers on growth, yield and quality of coriander (Coriandrum sativum L.) in a semi-arid tropical climate, 2010)
Nutritional Profile of Coriander
Adding a tablespoon of dried coriander to the diet nourishes the body in the following ways:
Macromolecules
A tablespoon of dried coriander only contains 0.4g protein, approx. 1g carbohydrates, and less than 0.01g lipid. (FoodData Central, 2019)
Minerals
Coriander intake guarantees at least 80g of potassium supply to the body.
Vitamins
Some of the important vitamins found in coriander are vitamin C, niacin, folate, and carotene.
Health Benefits of Coriander
Treatment for Diabetes
In one animal-based research, scientists treated a group of mice with coriander to investigate its anti-hyperglycemic effects. Observations and findings revealed a marked reduction in their blood glucose level, making it a beneficial ingredient for diabetic patients. (Rajeshwari & Andallu, 2011)
Chemistry of Coriander
Aldehyde compounds and essential oils make the two pillars of the coriander’s chemistry.
Although the essential oils chemical makeup is complicated, the aldehydes are relatively simple. The trio of aldehyde compounds that impart aroma to coriander’s leaves is 2-decenoic acid, decanoic acid, and tetradecenoic acid. (Mandal & Mandal, 2015)
Moreover, extensive research has been conducted to analyze the coriander’s essential oils composition, which heavily relies on cultural conditions and environment. Despite that geographical variations, a certain class of chemical compounds have been consistent in their essential oils. These include alcohols like linalool, ketones including camphor, and esters.
