Modeling Of Energy Consumption Of Cucumber Greenhouses Usingartificial Neural Network And Anfis, Zahra Ebrahimpour, Vali Sharabiani, Ebrahim Taghinezhad

Emirates Journal for Engineering Research

Optimal use of energy is a key requirement for sustainable agriculture. However, the growing demand for food has increased the energy consumption of the agricultural sector. Since the agricultural sector is the main sector of energy conversion, we focused on evaluating the efficiency of cucumber greenhouses in East Azerbaijan Province by artificial neural network and ANFIS. So, 135 cucumber producing greenhouses were sampled, and data were collected with an interview questionnaire. Finally, the inputs and output energy, the energy indices and the energy consumption of cucumber greenhouse was assessed and modeled. Among the inputs, fuel and seed had the highest …

Data From: Cavitation Clusters In Lipid Systems – The Generation Of A Bifurcated Streamer And The Dual Collapse Of A Bubble Cluster, Silvana Martini, Peter Birkin, Tadd T. Truscott

Browse all Datasets

Over the past decade several studies have reported the use of high intensity ultrasound (HIU) to induce the crystallization of lipids. The effect that HIU has on lipid crystallization is usually attributed to the generation of cavities but acoustic cavitation has never been fully explored in lipids. The dynamics of a particular cavitation cluster next to a piston like emitter in an oil, was investigated in this study. The lipid systems, which are important in food processing, are studied with high-speed camera imaging, laser scattering and pressure measurements. A sequence of stable clusters were noted. In addition, a bifurcated streamer …

Effects Of Poor Sanitation Procedures On Cross-Contamination Of Animal Species In Ground Meat Products, Sunjung Chung, Rosalee S. Hellberg

Food Science Faculty Articles and Research

The presence of <1% of an undeclared species in ground meat is generally thought to be indicative of cross-contamination as opposed to intentional mislabeling; however, this has not been experimentally tested. The objective of this study was to quantify the effects of poor sanitation on the cross-contamination of animal species in ground meat products, with the example of undeclared pork in ground beef. Cross-contamination was quantified using real-time polymerase chain reaction (PCR). Three different sanitation treatments were tested with a commercial grinder (“no cleaning”, “partial cleaning”, or “complete cleaning”) in between grinding of pork and beef samples (13.6 kg each). A 100-g sample was collected for each 0.91 kg (2 lb) of beef processed with the grinder and each sanitation treatment was tested twice. For the “no cleaning” treatment, the first 100-g sample of ground beef run through the grinder contained 24.42 ± 10.41% pork, while subsequent samples (n = 14) contained <0.2% pork. With “partial cleaning,” the first sample of ground beef contained 4.60 ± 0.3% pork and subsequent samples contained <0.2% pork. Pork was not detected in ground beef following “complete cleaning.” These results indicate that incomplete cleaning of grinding equipment leads to species cross-contamination at levels of <1% in most cases. Proper sanitation procedures must be followed when grinding multiple species in order to prevent cross-contamination and product mislabeling.

Modeling Of Free Chlorine Consumption And Escherichia Coli O157:H7 Cross-Contamination During Fresh-Cut Produce Wash Cycles, Mohammadreza Dehghan Abnavi, Ali Alradaan, Daniel Munther, Chandrasekhar R. Kothapalli, Partha Srinivasan

Mathematics and Statistics Faculty Publications

Controlling the free chlorine (FC) availability in wash water during sanitization of fresh produce enhances our ability to reduce microbial levels and prevent cross-contamination. However, maintaining an ideal concentration of FC that could prevent the risk of contamination within the wash system is still a technical challenge in the industry, indicating the need to better understand wash water chemistry dynamics. Using bench-scale experiments and modeling approaches, we developed a comprehensive mathematical model to predict the FC concentration during fresh-cut produce wash processes for different lettuce types (romaine, iceberg, green leaf, and red leaf), carrots, and green cabbage as well as …

Heat-Dependent Desorption Of Proanthocyanidins From Grape-Derived Cellwall Material Under Variable Ethanol Concentrations In Model Wine Systems, Jordan W. Beaver, Konrad V. Miller, Cristina Medina-Plaza, Nick Dokoozlian, R. Ponangi, T. Blair, D. Block, A. Oberholster

Chemistry Faculty Publications and Presentations

Desorption of proanthocyanidins (PA) fromgrape cell wall material (CWM) was investigated in solutions of varying ethanol concentrations and increasing temperature. The results reveal the reversibility of PA-CWM interactions and the role that temperature and ethanol concentration play in the extent of PA desorption. Sequentially raising temperature from 15 to 35 °C resulted in desorption of up to 48% of the initial adsorbed PA. A comparison to a phenolic extraction model showed significant differences between the predicted and actual amount of PA that desorbed from the CWM. This suggests that the initial conditions of temperature and ethanol concentration must be considered …

Formation Of Low Density And Free-Flowing Hollow Microparticles From Non-Hydrogenated Oils And Preparation Of Pastries With Shortening Fat Composed Of The Microparticles, Joshua Gudeman

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Solid fats provide critical functionality in the structuring, shortening, and stabilizing of many foods. However, their use as an ingredient is foods can present a number of challenges. The physical properties of solid fat can make them difficult to apply to or incorporate into foods consistently. On an industrial food production scale, handling of solid fats can difficult because they are often packed in heavy cubes or totes, and production delays and inefficiencies may be caused by the need to remelt the oils before use. Oils as a macronutrient also contribute a relatively high number of calories at 9 calories …

Food and Machinery

Thirty rats were randomly divided into normal control group (group A), non-paederia scandens treatment model group (group B) and paederia scandens treatment model group (group C). The expression of mRNA of TGF-β1, Smad3 and Smad7 was detected by real-time quantitative fluorescence method after 8 weeks. The results showed that, according to the ELISA data of interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), the difference between group C and group A was extremely significant (P<0.01), which is the same as between group B and group A, and that the difference between group C and group B was significant (P<0.05). The difference between group B and group A was extremely significant (P<0.01). After treatment with paederia scandens, the expression of TGF-β1 mRNA was significantly inhibited, the difference between group C and group A was significant (t=2.245, P<0.05), and the difference between group C and group B was extremely significant (t=1.142, P<0.01). After treatment with Paederia scandens, the expression of Smad3 mRNA was significantly inhibited, the difference between group C and group A was significant (t=2.149, P<0.05), and the difference between group C and group B was extremely significant (t=1.206, P<0.01). Afterwards, the expression of Smad7 mRNA was increased, the difference between group C and group A was significant (t=2.201, P<0.05), and the difference was significant between group C and group B (t=1.007, P<0.01). Paederia scandens can inhibit the expression of TGF-β1 mRNA, decrease the expression of Smad3 mRNA, and increase the expression of Smad7 mRNA. It is shown in our study that in the mechanism of liver fibrosis, there exists a linear channel effect of Smad3 mRNA-(TGF-β1 mRNA)-Smad7 mRNA.
