Mediterranean milk and milk products

Area of Science:

• Food Science
• Dairy Technology
• Human Nutrition

Background:

• Milk and dairy products are integral components of a healthy Mediterranean diet.
• Milk proteins are rich in essential amino acids and possess various biological functions.
• Different animal milk species (cow, sheep, goat, buffalo) offer slightly varying compositions but are nutritionally significant.

Purpose of the Study:

• To present the technology of Italian and German cheese types, focusing on nutritional aspects.
• To analyze the nutritional differences and correspondences in various cheese varieties.
• To highlight the specific case of Ricotta cheese production from whey and cream.

Main Methods:

• Comparative analysis of milk fat and protein composition across different animal species.
• Detailed examination of cheese-making technologies, including traditional Italian and German methods.
• Nutritional evaluation of cheese products, with a focus on whey protein utilization.

Main Results:

• Milk proteins are characterized by a high content of essential amino acids.
• Ricotta cheese, made from whey and cream, effectively utilizes valuable whey proteins.
• Whey proteins are rich in lysine, methionine, and cysteic acid, surpassing casein and soy protein content.
• Technologies exist to enrich cheeses with whey proteins, improving flavor and nutritional value.

Conclusions:

• Dairy products are a priority in human nutrition due to their protein and amino acid profiles.
• The utilization of whey proteins in cheese production, like in Ricotta, enhances nutritional value.
• Technological advancements allow for increased whey protein content in cheeses, improving low-fat options.
