In this process, microbiological contamination is common, which is prevented or eliminated by adding isothiazolone based biocides combined with other active components. The objective of this study was to evaluate the efficiency of two commercial biocides containing the active components, 5-Chloro-2-methyl-2H-isothiazol-3-one (CIT) and 2-Methyl-2H-isothiazol-3-one (MIT), in the inactivation of two Staphylococcus warneri strains, isolated from contaminated water from tanks of an e-coat paint applicator company. The Minimum Inhibitory Concentration (MIC) was 5 mg/L and the Minimum Bactericide Concentration (MBC) was 10 mg/L for both biocides. Survival curves were obtained and the Weibull model was adjusted. The models obtained indicated lower resistance of S. warneri strain isolated from the demineralized water tank and higher inactivation rate of the biocide containing the association of isothiazolinone and ethylenedioxy (dimethanol).","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115656872","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 honey samples appeared to conform to the European Legislation (EC Directive 2001) for most of the parameters. The moisture content of the samples varied between 13.5 to 19.5g/100g, Indian honey were the highest moisture content. PH values ranged between 4.7 to 5.6, all tested samples were light acidic. Electrical conductivity ranged from 0.13 to 1.4mS /cm. The color intensity values ranged between 137.3 to 624.7mAU. HMF content fluctuated between 15.4 to 19.9 mg / kg. The ash content varied from 0.05 to 0.68%. The total protein content varied between 0.61 to 1.9 %. The diastase activity values ranged between 9.6 to 11.9 DN. The Kashmiri honey showed the highest value of reducing sugars (64.6 g/100g), while Acacia honey showed the lowest value (59.9 g/100 g) The estimated fructose/glucose ratio for all investigated samples was ranged from 1. 03 to 1.37 and estimated glucose/water ratio was ranged from 1.48 to 1.90. Potassium was found to be the predominant mineral in all honey tested. The highest Potassium content (2176.4 mg/kg) was found in Sidr Yemeni honey. The heavy metals were not detected in all honey samples, that the tested honey was safe for human consumption. The results suggest that Indian and Yemeni honey could be beneficially used as a functional or nutraceutical substance.","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134225263","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 purpose of the present study was to describe the physical and chemical characteristics of the pulp of C. brasiliense Cambess collected in two cities of Minas Gerais, as well as its content of phenolic compounds. The fruits of C. brasiliense Cambess were collected in two cities in Minas Gerais: the Ponto Chique and the Jequitai on the ground after a natural fall, being submitted to hygiene and manually pulped. Then, the fruits underwent physical and chemical analyzes. To determine the nutritional composition of the fruits, moisture, ash, lipids, proteins, and total carbohydrates were analyzed. In order to prove the bioactive potential of the pequi pulp, an analysis of total phenolic compounds was carried out. The evaluation of the physical and chemical composition of the pulp of C. brasiliense Cambess from different cities in the north of Minas Gerais showed only physical differences and in the contents of phenolic compounds, possibly due to the great geographical proximity. However, further study is needed to determine the viability of pequi pulp as well as the fruits native to different regions of Minas Gerais. Both pulps stood out because of their considerable lipid and ash concentrations. Through the results, the potential of C. brasiliense Cambess was determined. There is evidence for significant antioxidant potential because of natural bioactive compounds present in the pulps.","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124613016","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}

Kefir and Cupuacu ( Theobroma grandiflorum Schum) have therapeutic potential for use in this field. In this study, a morphological and statistical analysis of the superficial distribution of bacteria and yeasts in kefir biofilms prepared with Cupuacu juice, obtained from the inoculation of kefir grains in brown sugar solution was performed. Six samples of different concentrations of the biofilms were obtained, which were analyzed in an Atomic Force Microscope to obtain topography images. Statistical analyses were performed on the surface parameters in order to determine the number and surface coverage of microorganisms in biofilms. The morphological analysis showed that the surfaces of the biofilms are composed of microorganisms similar to bacteria and yeasts. Statistical analysis showed that biofilms with a concentration of Cupuacu between 10 and 40 g.L -1 present a greater number and coverage of bacteria. All results show that the Cupuacu 10 g.L -1 biofilm presented the most appropriate, considering that it presented a higher number and coverage of bacteria, which is the antibacterial agent. In this perspective, the results indicate that there is an expectation of biofilms to result in a future application in the pharmaceutical industry.","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129769859","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}

However, in Brazil, a large part of the whey is still not adequately disposed. In this context, the production of carbonated beverages based on whey is an alternative to be considered. However, it is necessary to evaluate the adequacy of the available technology as well as the economic viability of the project in different scenarios before deciding on its implementation. Thus, in this work, mathematical modeling and simulations were proposed to analyze the economic scenarios of the production process of a carbonated beverage based on fermented milk whey added with hibiscus flower extract (Hibiscus sabdariffa L.). The industrial process was structured in four sections: preparation of the fermented whey, preparation of the glucose syrup, preparation of the hibiscus flower extract and preparation of the final drink. The best results were obtained for a whey processing volume of 7,000 kg per batch. The project presented an Internal Rate of Return of 49.77% and a Time of Return of Capital of 10 months. These results show the potential use of whey in the production of carbonated beverages.","PeriodicalId":119762,"journal":{"name":"Journal of Bioenergy and Food Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127982240","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}
