Determination of Color in Wheat: Affecting Factors and Analysis Methods
Why Color Determination in Wheat?
Characteristics of Wheat Grain
Wheat, one of the world's most widespread and important cereals, is of great plant and nutritional importance and is widely used as a staple food.
Wheat grain consists of three main parts:
- Bran (Pericarp): The outer shell of the wheat grain. It is responsible for protecting the seed from external factors and preventing water loss. It is rich in fiber, minerals, vitamin B and phytochemicals.
- Endosperm: It is the part that makes up the bulk of the grain, rich in starch and protein, carbohydrates and small amounts of vitamins and minerals. It provides energy during the development of the plant. It is consumed as flour by grinding.
- Germ: It is the embryo part of the seed. As the part that enables new plant formation, it is rich in protein, fat, vitamins (especially vitamin E) and minerals. It contains all genetic information and nutrients.
Uses of Wheat
- Flour Production: The flour obtained by grinding is used in the production of bread, pasta, biscuits and other bakery products.
- Animal Feed: Also used as animal feed.
- Fermentation: It is used in the fermentation process in alcohol and beer production.
- Other Products: Wheat is also used in the production of starch and gluten.
What are the Types of Wheat?
- Soft Wheat: Preferred for bakery products.
- Hard Wheat: Preferred for durum flour production.
- Spelt Wheat (Emmer, Einkorn, Spelt): They are older varieties and contain more fiber.
Determination of Color in Wheat
It is an analysis to determine and classify the quality of wheat. Generally, color can give an idea about the appearance and maturity of wheat. First of all, information about the variety and type of wheat can be obtained by color determination.
Factors affecting the color of the grain are as follows:
- Increased hardness darkens the color.
- Natural conditions
- Harvest season
- Diseases
- Storage conditions
Methods of Color Determination in Wheat
- Visual Review
- Spectrophotometric Analysis
- Digital Imaging Analysis
- Chemical Analysis
Importance of Color Determination
- Quality Control: Color is a factor in determining the maturity and quality of wheat. It also affects the performance of wheat in processed products.
- Classification: Color is an important criterion for the classification of wheat species and varieties.
- Marketing: Consumers generally prefer wheat products of a certain color. Color determination therefore also plays an important role in marketing strategies.
