Article Abstract
Oca (Oxalis tuberosa), a potato like crops, is cultivated extensively in the high altitude regions of the Andes. Traditionally, consumers have used sunlight to enhance the sweetness of oca and have used methods to produce a dehydrated product known as 'khaya' for its preservation. This research seeks to assess the chemical and nutritional changes that four oca cultivars undergo after exposure to sunlight and traditional dehydration techniques. The results of the study indicate that exposure of freshly harvested oca to sunlight contributes to antioxidant capacity, increased concentration of polyphenols, carotenoids and polyunsaturated fatty acids, and an overall improvement in nutritional properties characterized by a reduction in oxalate content and a significant increase in sugar concentration. On the other hand, dehydration byproducts are associated with a decrease in antioxidant capacity and polyphenols, a reduction in oxalate content and is accompanied by an increase in amylopectin. The changes in sugar content depend on the specific dehydration treatment used. Taken together, these results suggest that exposure of oca to sunlight not only improves its chemical and nutritional profile, but also contributes to an overall improvement in quality. On the other hand, dehydration of oca serves as a preservation technique, extending its shelf life while maintaining certain nutritional properties. This research provides valuable insights into optimizing the post-harvest handling of oca to improve quality and prolong shelf life.

Phytic acid is a phosphorylated derivative of myo-inositol that is ubiquitous in plants and serves as the primary storage form of phosphorus. In human nutrition, phytic acid is considered an anti-nutrient because it chelates essential minerals, including calcium, iron, and zinc. This binding action reduces the bioavailability of these metals, highlighting the importance of monitoring phytic acid in food.

Background: Targeted bottom-up proteomics is of great interest for the straightforward, accurate, and sensitive measurement of specific protein biomarkers from surrogate peptide fragments. However, this approach typically relies on off-line enzymatic digestion with trypsin, a time-consuming step that may be inadequate for covering certain sequence regions containing important post-translational modifications (PTMs).
Results: In this study, we present an in-line enzymatic digestion strategy for the targeted bottom-up analysis of α-synuclein (α-syn), which is a protein biomarker of Parkinson's disease (PD).
