Maize kernel nutritional quality-an old challenge for modern breeders

Area of Science:

• Agricultural Science
• Nutritional Science
• Biochemistry

Background:

• Maize is a globally significant cereal crop, essential for food and animal feed.
• Maize kernels are a primary source of vital nutrients for both human and animal diets.
• The nutritional quality of maize directly influences global health and nutrition.

Purpose of the Study:

• To provide a comprehensive overview of the nutritional composition of maize kernels.
• To summarize current knowledge on starch, protein, oil, and carotenoid content in maize.
• To identify knowledge gaps and suggest future research directions.

Main Methods:

• Literature review of existing studies on maize kernel composition.
• Synthesis of data on starch, protein, amino acid, oil, and carotenoid levels.
• Analysis of current research trends and identification of future research needs.

Main Results:

• Detailed summary of starch, protein, oil, and carotenoid content in maize kernels.
• Information on the amino acid profiles within maize protein.
• Identification of key nutritional components and their variability.

Conclusions:

• Maize kernels possess significant nutritional value due to their starch, protein, oil, and carotenoid content.
• Further research is needed to fully understand and optimize maize's nutritional profile.
• This review highlights areas for future investigation to enhance maize's role in global nutrition.
