Targeted healthy compounds in small and large-scale brewed beers

Area of Science:

• Food Chemistry
• Brewing Science
• Nutritional Analysis

Background:

• Beer is a popular beverage globally, with varying nutritional profiles.
• Understanding the healthy compound content in Italian beers is important for consumers and producers.
• Small-scale and large-scale brewing processes may influence the final product composition.

Purpose of the Study:

• To quantify key healthy compounds in popular Italian small-scale and large-scale brewed beers.
• To compare the levels of these compounds between different brewing scales.
• To investigate the influence of brewing scale and beer style on compound content.

Main Methods:

• Quantification of nitrogen compounds, fermentable sugars, total phenolic content, antioxidant capacity, beta-glucans, pyridoxine, folates, silicon, and amines.
• Analysis of popular small-scale and large-scale brewed beers from Italy.
• Statistical analysis to compare compound levels and identify correlations.

Main Results:

• Small-scale beers showed significantly higher levels of total phenolic content, antioxidant activity, nitrogen, folate, and putrescine.
• Beer style significantly impacted statistical results, necessitating careful comparison between styles.
• A positive correlation was observed between total phenolic content and EBC color.
• Pyridoxine, beta-glucans, and fermentable sugars varied widely in both scales; silicon content was similar on average.

Conclusions:

• Small-scale Italian beers may offer higher concentrations of certain beneficial compounds.
• Brewing scale and beer style are critical factors influencing the nutritional composition of beer.
• Further research is needed to fully elucidate the impact of brewing practices on beer's healthy compound profile.
