The main objective of the research was to evaluate the effect of biochar (BC) derived from pig manure on the availability of Pb in a contaminated and limed agricultural soil. A randomized experimental design was applied, the pig manure was dried at room temperature (23 °C) and pyrolyzed at 500 °C for 2 h. Doses of 5%, 10% and 20% of BC were applied to the Pb soils contaminated (165.7 mg/kg), that were arranged in 2 kg pots except for the control sample, and Lactuca sativa was subsequently grown cultivated to evaluate the Pb availability. The results indicated an improvement in soil quality at higher BC dose, increase of 0.34 pH units, decrease of Pb extracted by EDTA (27% to 62% of decrease), and non-significant Pb content in leachates (< 1 mg Pb/L) and no detection in plant roots (< 0.01 mg/kg), except for the control plant (0.7 mg Pb/kg) in the original soil. A logarithmic relational model between BC dose and Pb adsorbed in the soil was obtained (R 2 = 0.9938, p < 0.05) showing that the decrease of Pb availability in the soil increased for higher BC doses, which represents an eco-friendly remediation alternative. It is recommended to investigate the interaction relationships between the soil quality parameters and to establish functional models of bioaccumulation and extractable metal of the amended soil.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46075604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ideal sensory profile of cabanossi with llama meat from three feeding systems (with natural hay, alfalfa and with vitamins) through the CATA method was determined in comparison with two commercial samples. Moisture, pH, water activity, color and texture were evaluated. Moisture and external and internal color were similar between llama cabanossi but different from commercial ones. The mechanical parameters (hardness and chewiness) were superior from the llama cabanossi samples. Eighty (80) consumers with an ideal profile based on CATA questions found significant differences in all of the used descriptors. The indispensable sensory attributes for their acceptability were: salty, characteristic smell/ sausage and chewiness. With regards to the penalty analysis, the positive attributes (chewiness, and bland/soft) and negative (hard, smell, smokey and brown color), which should be considered for product reformulation. The cabanossi from natural hay feeding system (CS1) was close to the ideal product. The use of the ideal profile constitutes an alternative to identifying the characteristics (sensory, physicochemical and mechanical) for the development of new foods based on the consumer ́s idealized requirements.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44174923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the objective was to perform a qualitative and quantitative analysis of the scientific contributions in agribusiness. A bibliographic consultation was made in Scopus and \"Agribusiness\" was used as keyword. A textual analysis was performed on 407 scientific papers from 2020, through Nvivo 12 software using the following analysis codes: Mega trade agreements and institutional harmonization, farm-level technology pricing and contracts, market power related to the mega consolidation of companies, new agricultural technologies, emergence of agrocorporations, institutional land access rules, property rights regimes and their consequences, private enforcement of property rights, farmer class action studies and territorial reconversion. Two more codes emerged in the analysis process: Environmental impact and human health impact. Current scientific contributions in agribusiness are focused on new agricultural technologies (24%), environmental impact (17%) and local actions of farmers (14%). A qualitative improvement of the contributions is observed as more elements that support the complex processes agribusiness generates are increasingly incorporated. From focusing on economic and financial aspects, sustainabilityoriented and social commitment domains are now considered. A modern and innovative concept defines agribusiness as economic activities with different forms or models of production, derived from or linked to agricultural products. It considers production-consumption processes and farmers are inserted in a differentiated way according to their economic rationality. These activities are not only focused on the generation of monetary value, but also on the social processes it produces, where multiple actors are involved.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48050046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the research was to evaluate the effect of the storage conditions on the main physicochemical components, primary and secondary metabolites, antioxidant, and hypoglycemic capacity during postharvest ripening, under two storage conditions: ambient (29 °C and 70% RH) and climatic chamber (15 °C and 90% RH). Regarding the physicochemical characteristics, the state of maturity influenced acidity, pH, reducing sugars, starch, dietary fiber, firmness, pulp color and epicarp. In climate-controlled storage, glucose is the only metabolite that increases; while fructose, alcohol sugars and amino acids (Ala and Val), present higher values under ambient conditions; sucrose, organic acids, amino acids (Tyr, Glu, Asp and Thr), β-carotene, total phenolic compounds and total carotenoids were not affected by the type of storage. The measure of antioxidant and hypoglycemic capacity decreased significantly (p < 0,05), showing to be affected only by the state of maturity. The study of the carotenoid profile according to its spectrum (UV-vis) showed the presence of the group of xanthophylls. The results indicate that the state of maturity concerning the storage condition influenced most of the changes studied.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46639097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incorporation of legume flours in food systems has been a growing trend in recent years. Therefore, this study evaluated the effect of the addition of chickpea flour on the physicochemical, rheological, and microstructural properties of yogurt. Different levels of chickpea flour (1, 2, and 3%) were added to yogurt and the evolution of systems were monitored on days 1, 8, 15, and 22 of storage. Results for pH (4.61 – 4.75), titratable acidity (0.58% 0.72%) and density (1048 1139 kg/m) showed no significant differences (p > 0.05), while higher concentrations of the flour resulted in lower levels of syneresis (15.90% 23.73%). The flow properties confirmed the non-Newtonian behavior in the systems, fitting the two Power Law and Herschel-Bulkley models, thus establishing a relationship between the experimental data and the variables under study. The microstructure analysis showed that a higher concentration of chickpea flour increases the porosity of the system. Finally, the results suggest that it is highly recommended to replace milk solids with chickpea flour, thereby maintaining the properties and stability of the product.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48425138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve stimuli were created by using a fractional factorial design considering packaging material, nutritional information, quality, convenience, and naturalness as factors, previously obtained by open-ended questions. Ninety-seven consumers answered an online survey indicating their expected acceptance, purchase intention and holistic perception. The results showed that the most salient factors for consumers, in terms of expected acceptance, purchase intention, and holistic perception, were packaging material and convenience. For these factors, the levels that increased expected acceptance and purchase intention were the \"package made of food grade paper\", conveniently adding a \"spoon and napkin\".","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44581457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
