The polymeric suspension of chitosan (Ch) has been an effective media for the extraction of total phenolic compounds (TPC) from the acerola by-product. It facilitates the subsequent production of nanoparticles loaded with the phenolics (Np-TPC) by ionic gelation. However, neither the effects of Ch concentration on encapsulation efficiency (EE%) of TPC nor which compounds are extracted in its media are known, being it the first objective of this study. The second objective was to analyze the stability of the Np-TPC under accelerated conditions and its release profile at pHs 3.0 and 7.0. The results showed that Ch does not affect the extraction of TPC. However, the EE increased from 35.0 to 48.1 % with the increase of Ch concentration (0.4 to 1.0 %). LC/ESI-QTOF MS analysis showed that phenolic acids and flavonoids are extracted in 0.8 % Ch medium. After encapsulation, microscopy images revealed particle sizes ranging between 110 and 150 nm. Additionally, the presence of phenolics did not change the stability of the particles under accelerated conditions and the actives were fully released into the released medium for 10 h. The Np-TPC suspension appears to be useful for the production of edible antioxidant coatings to preserve fruits/vegetables, with potential application as carrier of other food ingredients. |

The elaboration of fish silage is an alternative to minimize the environmental and sanity problems from fish residue. The objective of this reseaarch was to select the most appropriate acid for the preparation of chemical fish silage; market analysis considering environmental and human risks, cost and supply of acidifying agent was performed. A review of major research on the production of acid silage was conducted to compare the different acids chosen and their respective methodologies. A market analysis considering the ease of acquisition of reagents as well as examination of the Material Safety Data Sheets (MSDS) was also conducted to assess the dangerousness of acid to the environment and human health. None of the acids used in research presents the three factors simultaneously satisfactory: cost, accessibility and hazardous to the environment and human health at the same time. The use of anhydrous citric acid seems to be the best choice; moreover, it is an organic acid, offers no major risks to health and environment, it is not a controlled product and has an affordable cost. |
