Nutritional evaluation of some processed catering foods

Area of Science:

• Food Science and Technology
• Nutritional Analysis
• Dietary Assessment

Background:

• Accurate nutritional information is crucial for catering, public health, and dietary management.
• Existing food composition databases vary in scope and origin, necessitating validation for complex recipes.
• Understanding the reliability of these databases against analytical data is essential for practical application.

Purpose of the Study:

• To evaluate the proximate composition, fatty acids, vitamin E, thiamine, and riboflavin content of prepared catering dishes.
• To compare the accuracy of international food composition databases (Italy, UK, USA) against analytical values.
• To determine the suitability of databases for assessing the nutritional content of complex recipes.

Main Methods:

• Analytical determination of proximate composition, fatty acids, vitamin E, thiamine, and riboflavin in five catering dishes.
• Calculation of nutrient values using data from multiple international food composition databases.
• Statistical comparison between analytical results and database-derived values.

Main Results:

• Average values calculated from databases closely approximated analytical values for the catering dishes.
• No significant statistical differences were found between analytical data and database values, or among the databases themselves.
• Variability was observed in some nutrient values, but overall database adequacy was demonstrated.

Conclusions:

• International food composition databases are generally adequate for evaluating the nutritional content of catering dishes, especially for group assessments.
• Direct laboratory analysis is recommended for precise nutritional profiling of individual, specific recipes.
• Databases can accommodate seasonal ingredient variations when assessing population-level dietary intake.
