Food Quality and Safety Studies
Research Guide

Food Quality and Safety Studies is the research field focused on measuring and managing food quality attributes (e.g., pigments, phenolics, proteins) and safety risks using validated analytical and microbiological methods. It includes method development, standardization, and application to real foods and food-related matrices. The provided corpus size is 113,491 works, reflecting broad use of shared measurement approaches.

"Determination of Total Monomeric Anthocyanin Pigment Content of Fruit Juices, Beverages, Natural Colorants, and Wines by the pH Differential Method: Collaborative Study" (2005) describes a rapid spectrophotometric pH-differential approach based on anthocyanin structural transformation with pH change. The method targets total monomeric anthocyanin concentration and is explicitly framed for fruit juices, beverages, natural colorants, and wines. Because it was a collaborative study, it is commonly treated as a standardizable protocol for inter-lab comparisons.

Swain and Hillis (1959) in "The phenolic constituents of Prunus domestica. I.—The quantitative analysis of phenolic constituents" critically examined and modified methods for quantitative analysis of anthocyanins, leuco-anthocyanins, flavanols, and total phenols in plant tissue extracts. The paper emphasizes suitability and modification of existing methods rather than proposing a single universal assay. These quantified phenolic measures are used as compositional indicators relevant to quality attributes such as color and astringency.

Hartree (1972) "Determination of protein: A modification of the lowry method that gives a linear photometric response" provides a protein determination method designed for linear photometric response, supporting more reliable calibration. Schacterle and Pollack (1973) "A simplified method for the quantitative assay of small amounts of protein in biologic material" targets small protein quantities, which is useful when sample mass is limited. Both are frequently adapted as general quantification backbones in food composition and processing experiments.

Kurtzman and Fell (1972) "The Yeasts. A Taxonomic Study" outlines classification and the phenotypic, ultrastructural, biochemical, and molecular properties used for yeast classification and provides extensive descriptions of taxa. Lodder (1984) "The Yeasts: A Taxonomic Study" similarly covers methods for isolation, maintenance, classification, and identification of yeasts and discusses major yeast groups. These works function as reference frameworks when yeasts are implicated in fermentation control, spoilage, or contamination source tracing.

Woessner (1961) "The determination of hydroxyproline in tissue and protein samples containing small proportions of this imino acid" provides an approach for quantifying hydroxyproline in samples where it is present at small proportions. Reissig et al. (1955) "A MODIFIED COLORIMETRIC METHOD FOR THE ESTIMATION OF N-ACETYLAMINO SUGARS" describes a colorimetric method for N-acetylamino sugars, which can be relevant when tracking certain carbohydrate-related constituents. Such assays are commonly used as targeted compositional markers to interpret processing changes or ingredient contributions.
