Edible insects in China: Utilization and prospects.

Area of Science:

• Entomology
• Food Science
• Sustainable Agriculture

Background:

• Edible insect consumption, or entomophagy, has a rich history in China spanning over two millennia.
• Insect consumption is widely accepted, with research exploring various aspects including nutritional value, farming, and safety.

Purpose of the Study:

• To provide a comprehensive overview of edible insect utilization in China.
• To document the diversity of edible insects, their nutritional profiles, and current farming practices.
• To assess the safety and potential of insects as a sustainable food and feed source.

Main Methods:

• Literature review of studies on entomophagy in China over the past 20 years.
• Compilation of data on documented insect species, nutritional values, and consumption patterns.
• Analysis of insect farming techniques and food processing innovations.

Main Results:

• 324 insect species from 11 orders are documented as edible or associated with entomophagy, though only 10-20 are regularly consumed.
• Nutritional data for 174 species confirm they meet human requirements for protein, fat, vitamins, and minerals.
• Insect farming is a significant rural industry, providing income and contributing to food and feed production.

Conclusions:

• Edible insects represent a safe, nutritious, and sustainable food and feed resource in China.
• Further collaboration between social and scientific communities is crucial to promote insect-based diets and industries.
• Indirect consumption via livestock fed insects offers a potentially more acceptable route for broader human dietary integration.
