This is due to the presence of potent secondary metabolites such as phenolics, and xanthones, which are differentially accumulated during ripening. However, the molecular regulation that governs mangosteen ripening and hence metabolic changes h ...

Abstract:
... Pineapple cubes in sugar syrup were treated with high-pressure processing (HPP), conventional (DIM) heating and ohmic heating (OHM). Samples were compared in terms of microstructural, physical (total soluble solids, sieve analysis, texture and colour) and residual pectin methylesterase activity (PME) and total antioxidant capacity. OHM yielded relevant changes in cellular microstructure and electr ...

Abstract:
... Peach (Prunus persica cv. Dajiubao) was chosen as a model to clarify the roles of IAA and ABA during the fruit ripening process. Seventy days after flowering (DAF), the fruits were treated with IAA and ABA (0.1 mmol·L−1 and 1 mmol·L−1, respectively) and with the IAA transporter inhibitor (NPA) and the ABA biosynthesis inhibitor (NDGA). IAA decreased the fruit ABA concentration, and increased ethyl ...

In this study, we developed a scalable process to extract phycocyanin from dried spirulina biomass. First, we established the optimal ionic strength and pH for the extraction buffer. The results showed that a minimum ionic strength (>5 g/L NaCl) must be ma ...
