The rheological behavior of fruit pulp is modified with the addition of encapsulants which in turn influences the energetic performance of spray drying. In such processes, both maltodextrin and gum arabic are used as encapsulants of fruit pulp and acting as sugars protectors and thus reducing caramelization reactions. The experiment was conducted under a completely randomized design with 2×4 factorial arrangements (Factors: encapsulants and concentration). A Rheometer (AR 1500ex) was used for conducting the flow trials on continuous ramp on the pulp with encapsulants concentrations of 15, 20, 25 and 30% (w/w). Ostwald de Waele’s model was adjusted to apparent viscosity data with determination coefficients greater than 0.994, apart from that, the consistency index (k) and the flow behavior index (n) showed significant differences (p≤0.05) between encapsulants and concentrations used. Those n values lower than one characterize the encapsulated pulp as pseudoplastic flow and the presence of hysteresis among the ascending and descending curves indicate that this is time-dependent fluid with thixotropic nature. The apparent viscosity of the pulp increased with the rise in the encapsulants concentration for the same shear rate, being the gum arabic the one with the greater values. Results will contribute to the improvement of the pump systems design of spray dryers.","PeriodicalId":7316,"journal":{"name":"Advance Journal of Food Science and Technology","volume":"518 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77145698","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}

Some factors that contribute to its contamination are the use of non-potable water, inadequate handling, cross-contamination and environmental contamination. This study aimed to perform a sanitary profile with the completion of a survey of 12 food stalls to evaluate their hygienic and sanitary quality and through observation. Four samples of food were taken from each stand, for a total of 48 samples such as hamburger, hot dog, pizza, meat empanada, stuffed potato, stuffed arepa, chicken skewer, chicken finger, fruit salad and orange juice. Coliforms, Escherichia coli and Staphylococcus aureus were analyzed. 83.3% of the samples exceeded the acceptable limits of coliforms and in the 16.7%, it was detected Escherichia coli . No S. aureus was detected in any sample. Eighty-three point three percent of the vendors do not wear appropriate clothing, 75% use accessories and 83.3% do not use potable water for hand washing. Thirty-three point three percent of the stalls do not have surface with sanitary material, 100% do not have access to sanitary service and drinking water, 58.3% have the presence of animals in their surroundings, 50% have uncovered garbage containers, 91.7% store food at high temperatures and 100% do not have a sanitary authorization of operation.

Enzymatic browning can be an undesirable phenomenon in many fruits and vegetables producing color alterations. These can reduce commercial value of food products, or even make them unacceptable to consumers. Following up this reaction through low cost and easy to use technological tools is very important to avoid quality losses. In this research study, different samples of avocado puree were prepared and analyzed under cooling and room storage. Color changes were analyzed using the CIEL*a*b, h° and C* coordinates and Color Index (CI) was calculated. For both storage conditions, L* value decreased for control and sample with citric acid added and CCI calculated did not show significant differences among analyzed samples. However, a maximum CIC value was obtained for the sample treated with citric acid and a minimum for the sample with lyophilized seed, which might give indications of inhibitory action of seed, independently of storage conditions. Through use of chromatic techniques, it was possible to follow color variations in avocado puree effectively.","PeriodicalId":7316,"journal":{"name":"Advance Journal of Food Science and Technology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81269105","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 evaporation is the elimination of solvent in form of water steam from a solution. In the dairy industry, the evaporation is a pretreatment for the powder milk processes that reduce the cost of the drying process, storage and transport. Thus, an appropriated mathematical model is necessary in order to get a good control and optimized process of milk evaporation, which allows obtaining a high-quality product. Previous studies have presented mathematical models for the evaporation process. However, the majority of these models are based on maintaining constant values such as the thermal properties of fluids, latent heat of vaporization and global coefficient of heat transfer, among others and this means that there will be high errors of predictions. The aim of this model was to predict the temperature, concentration and milk level in the evaporator. The model obtained was solved using the Runge-Kutta method with the software “LABVIEW 2011” and it was quantitatively validated with experimental data from a real process using the absolute mean error. The experimental data of temperature, concentration and milk level in the evaporator were obtained applying step-like disturbances in the process variables: vacuum pressure in the evaporation chamber, steam flow and milk feeding flow. The quantitative validation showed that the obtained model can predict satisfactorily the dynamic behavior of the target variables of the milk evaporation process because the error was less than 5%.","PeriodicalId":7316,"journal":{"name":"Advance Journal of Food Science and Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84422611","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}
