Shotgun Metagenomic Approacheses those processes implying sourdough stability and resilience..In this view, this chapter elucidates concepts related to those taxa identified as mainly responsible for the resilience and robustness of this ecological niche. Moreover, following a theoretical workflow, this chapter provides an up-to

Determination of the Content of Free Amino Acids and Their Profilingwithstanding the high reproducibility and the possibility to quantify up to 56 amino acids and derivatives, the long time of analysis can be inconvenient if large numbers of samples are to be analyzed or if the goal is to just quantify total FAA. In such cases, rapid spectrophotometric assays like t

Soluble Sugars and Polysaccharidesime, the higher costs of analysis per sample compared to lab-developed methods tip the scale in favor of the latter..Whereas soluble sugars can be easily extracted and separated through high performance liquid chromatography, starch quantification needs to be preempted by its hydrolysis to glucose.

Image Analysisound pixels can be distinguished by selection of an optimal gray level value. Hundreds of segmentation techniques are described in the literature, yet the Otsu method, based on an algorithm that minimizes the intraclass variance of the segmented region, or manual thresholding, is those most reported

Determination of the Volatile Components VOC detection, by using a method for volatile extraction based on headspace solid phace microextraction (HS—SPME). This chapter will provide a description of HS-SPME GC-MS analysis for the evaluation of volatile compounds in sourdough bread including sample treatment, HS-SPME conditions, GC-MS cond

Der Begriff des intelligiblen Charaktersicroorganisms are governed by a multitude of ecological factors. Indeed, in-depth studies of the biodiversity of the microbiota of traditional sourdough products are interesting from an academic and industrial point of view. Since not all sourdough microorganisms are easily cultivated in common labo
