Furthermore, high-speed shearing is widely used in the food industry, demanding high shear, cavitation, and collision force. In this sense, high-speed shearing could reduce the size of OSA droplets and promote a more homogeneous distribution of groups in the starch granule. The aim of this study was to evaluate the impact of OSA potato starch synthesis assisted by high-speed shear on structure (SEM and FTIR), gelatinization, rheology, and emulsifying activity (ES and AS) was investigated. The results showed a gradual increase in DS proportional to the applied speed. Likewise, the OSA starches showed a slight alteration in the shape of the granules (SEM), and FT-IR spectroscopy showed a characteristic absorption of the ester carbonyl groups in the OSA starch at 1724 cm-1. The high-speed shear-treated starches exhibited a significant change in the reduction of the initial gelatinization temperature, although not in the enthalpy. All the gels presented rheology adjusted to the Herschel-Bulkley model with variations in the initial shear stress. Changes in the viscoelastic behavior are proportional to the shear rate detected. High-speed shear treatment did not show a significant effect on emulsion stability (ES) and emulsion activity (EA). Consequently, applying high shear rates allows having OSA starches with different uses.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46094529","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}

For this, 25 papers related to the VESS (2009-2022) were considered where the information of the authors, the soil property: bulk density (BD), total soil porosity (TP), soil penetration resistance (PR), macroporosity, microporosity, soil organic carbon (SOC), and mean weight diameter of stable aggregates (MWD). The sample size (n=120 cases), and the correlation coefficient were extracted. To measure this relationship, the correlation coefficient of all studies was contemplated. A meta-analysis was carried out to obtain a global measure of the correlation between the VESS and soil properties across the studies. In the first instance, a fixed effects model was fitted for the correlation (effect size, known as the response variable in the meta-analysis). Subsequently, a random effects model was fitted for the correlation, followed by a subgroup analysis according to soil properties, due to the presence of high heterogeneity between studies. The overall effect (average correlation coefficient) of the fitted random effects model was 0.31 with a confidence interval (CI) of [0.22;0.41]. The heterogeneity between studies was high ( =94.0%) and statistically significant p<0.001. Although it is moderate, the average correlation in practical terms may be sufficient. There were significant differences in some average correlations of some categories, such as BD, PR, TP, and microporosity. The weights reported for the BD, SOC, and PR were 29.7%, 16.4%, and 14.2%, respectively. This result evidenced that the greatest contribution to the global effect of correlation between VESS and soil properties is provided by BD.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44215841","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}

This study aims was to perform a systematic analysis based in SCOPUS of scientific productions of studies on techniques for detection and identification of flavonoids by HPLC-MS in fruit waste available in Latin America, between the years 2010-2022. Thus, the countries with the highest scientific production are Brazil (58.9%), Mexico (16.1%), Chile (9.2%), Argentina (7.1%) and Colombia (3.8%). There were also studies in collaboration with researchers from the USA and Europe. A total of 15.1% of the studies used HPLC-MS for determining these compounds, generally related to by-products of native or non-traditional fruits. It is known that agro-industrial waste matrices are chemically complex, being necessary analytical techniques such as HPLC-MS, which awakens interest for their study and the possibility of being isolated from vegetable by-products such as fruits. This is a green technology alternative to achieve sustainable use of this waste and be exploited by the food industry.","PeriodicalId":21642,"journal":{"name":"Scientia Agropecuaria","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67610396","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 cereals formulated with 50% and 75% PM had the best scores (6) in color, aroma, texture, and overall liking during the acceptability test. Based on the penalty-lift analysis, Brazilian consumers' most important drivers of preference were the attractive color, crispy texture, and the natural and innovative purple color. In contrast, hard texture and brown color drivers negatively impacted the scores. In the market research, consumers indicated that they could eat the product both as a breakfast cereal and as a snack during the day; Likewise, they highlighted the possible health benefits, the innovative color, and the use of exotic raw materials as the best characteristics of the product.

The genera of isolated Actinobacteria were identified, the synthesis of 1-aminocyclopropane-1-carboxylic acid deaminase (ACC) was characterized and its effect on the germination of tomato cultivar Río Grande seeds was evaluated. Two tests on non-saline and saline soils were carried out to compare the effect of Streptomyces spp. and Nocardia sp. in plant development in the greenhouse. Several Actinobacteria genera were isolated from 87.03% of samples, highlighting Streptomyces (46.67%) and Nocardia (34.0%). 9.33% of the Actinobacteria presented ACC deaminase activity, which increased seed germination, and the growth and yield of seedlings with increases of 88.98% (height); 96.30% (number of sheets); 201.35% (aerial biomass); 173.77% (root length); 100.0% (root weight); 150.0% (number of fruits) and 173.14% (weight of fruits), as well as 1.37 mg/g in the chlorophyll content in the saline soil. Also, Streptomyces sp. strain 21 decreased sodium content and increased potassium and K+/Na+ rate in the leaves and roots of the plants with the highest yield (1.068 kg/plant) in the saline soil.

For this, the bamboo species were collected: Bambusa vulgaris, Gigantochloa apus, and Guadua weberbaueri were through destructive methods, collecting three culms from different bushes and obtaining samples at different heights of the culm (base, intermediate and apex). The anatomy was performed at the base of the culm and the physical properties at the three axial positions. The results show that at the anatomical level, there is a difference between the three species mainly due to the vascular bundles, on the physical properties there was also a difference between species and the variation in the axial direction there was variation in the three positions, in addition, the grouping analysis showed that the species Bambusa vulgaris and Gigantochloa apu form a group due to their anatomical characteristics and physical properties, while Guadua weberbaueri was not grouped with either.
