Microbes in Beverage Production01:25

Microbes in Beverage Production

Alcoholic beverages such as wine, beer, and spirits are the products of microbial fermentation processes that transform simple sugars into ethanol and a wide array of complex flavor compounds. These transformations rely on the metabolic activities of specific yeasts and bacteria, which are selected and controlled to yield the desired beverage characteristics.Wine Fermentation and MaturationWine production begins with the crushing of grapes to release juice and pulp, forming a must that is...

Microbes in the Production of Fermented Foods

Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
Applications of Molecular Taxonomy01:20

Applications of Molecular Taxonomy

Molecular taxonomy has revolutionized the understanding and classification of bacteria, providing precise insights into their diversity, evolutionary relationships, and ecological roles. By utilizing molecular techniques such as DNA sequencing and fingerprinting, researchers have made significant strides in various fields related to bacterial studies.Resolving Taxonomic AmbiguitiesMolecular taxonomy has been instrumental in distinguishing closely related bacterial species initially thought to...

Modern Molecular Taxonomy

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...
Microbes in Food Production01:29

Microbes in Food Production

Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
Microbial Spoilage of Food01:23

Microbial Spoilage of Food

Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...

Area of Science:

  • Analytical Chemistry
  • Food Science
  • Geochemistry

Background:

  • Consumer demand for foodstuff provenance is increasing.
  • Traceability in wine production is crucial for quality assurance.
  • Lanthanides offer potential as chemical markers for traceability.

Purpose of the Study:

  • To investigate the use of lanthanide distribution for tracing Moscato d'Asti wine production.
  • To determine if soil's lanthanide fingerprint is maintained through the wine production chain.
  • To assess geographical origin and detect adulteration in Moscato d'Asti musts.

Main Methods:

  • Sampling at various stages of Moscato d'Asti production (soil, grapes, must, wine).
  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for lanthanide analysis.
  • Analysis of 102 Moscato d'Asti must samples for geographical profiling.

Main Results:

  • Lanthanide fingerprints remained consistent from soil to grapes to must.
  • Fractionation of lanthanides was observed during wine clarification with bentonites.
  • Distinct lanthanide profiles in musts can potentially reflect geographical origins.

Conclusions:

  • Lanthanides are effective markers for tracing Moscato d'Asti from soil to must.
  • Bentonite clarification alters the lanthanide profile, impacting traceability at later stages.
  • Lanthanide analysis of musts provides a basis for geographical authentication and adulteration detection.
