The objective of this work was to obtain a protein hydrolysate from the wastewater generated during shrimp cooking, by coupling ultrafiltration and enzymatic hydrolysis processes. Initially, the effluent was concentrated by ultrafiltration, reaching a protein concentration factor of 3.2. The concentrated effluent was then enzymatically hydrolyzed, aiming at obtaining peptides with antioxidant capacity. The effects of some process variables ? temperature (55?75 C), pH (7?9) and enzyme/substrate (E/S) ratio (0.1?2.5%) ? on the degree of hydrolysis and the antioxidant capacity were evaluated. The increase in temperature and pH resulted in lower degree of hydrolysis and higher antioxidant capacity. The conditions selected as the most suitable were: temperature of 75 C, pH of 9.0 and E/S ratio of 0.1%. The hydrolysates produced at these conditions were also evaluated for total amino acid content and electrophoretic profile, showing a suitable amount of essential amino acids that covers the recommended daily needs. |

Manual static chamber is one of the most widespread methods for the quantification of greenhouse gases (GHGs) emission from agricultural systems. But there are concerns about the reliability of measurements and a necessity to assess the static chambers used in the studies performed in the countries of Latin America. Thus, this study aims to investigate the quality of static chambers used for GHGs measurement in scientific articles following international recommendations and assess the confidence level of static chambers. A systematic review of databases was conducted to identify peer-reviewed articles that used the static chamber method in Latin América. A total of 90 articles were analyzed and separated according to the publication year (2000- 2008, 2009-2015, 2016-2020). This time interval was selected to assess the influence of key publications with guidelines and criteria for the method published in 2008 and 2015. Six design and deployment chamber characteristics were evaluated. The chambers received a global score for a confidence level according to their characteristics scores and the weight of each one. The percentage of articles with high confidence level increased within the time, and the number of articles with low confidence level reduced. Researchers should continue to follow the Global Research Alliance protocols, especially the most updated ones. |
