Effect Of Pretreatment Of Soy Insoluble Fiber And Sscf With Saccharomyces Cerevisiae And Escherichia Coli Ko11 On Ethanol Production In An Integrated Corn-Soy Biorefinery, J. K. Sekhon, D. Maurer, K. A. Rosentrater, T. Wang, Stéphanie Jung

Stéphanie Jung

Soy insoluble fiber (IF), co-product of enzyme-assisted aqueous extraction process (EAEP) of soybeans, is rich in carbohydrate and protein. It can be used to enhance ethanol production in an integrated corn-soy biorefinery, which integrates components from soybean processing into corn-based ethanol processing. However, cornstarch and IF have unique carbohydrate compositions that require different treatments for optimal fermentation. The present study investigated the effect of pretreatment method [soaking in aqueous ammonia (SAA), liquid hot water (LHW), and enzymatic hydrolysis], simultaneous saccharification and co-fermentation (SSCF) with Saccharomyces cerevisiae and Escherichia coli KO11, and scaling up from bench scale (150 mL) to pilot ...

Michelle L. Soupir

Particulate matter (PM) concentrations are high in cage-free aviary hen houses due to accumulation of litter on the floor and hen activities. The use of a spraying agent such as acidic electrolyzed water (AEW) to mitigate PM levels and disinfect houses has been reported, and high spray dosages will reduce PM to a low level. However, spraying a high dose of AEW may generate high levels of ammonia (NH3) due to an increase in litter moisture content (LMC). Lab-scale experiments were conducted to assess the effect of AEW spray dosage and pH on PM and NH3 emissions from the litter ...

Effect Of Red Cabbage Extract On Minced Nile Perch Fish Patties Vacuum Packaged In High And Low Oxygen Barrier Films, Ayse Demirbas, Yavuz Yagiz, Ziynet Boz, Bruce A. Welt, Eric Mclamore, Maurice Marshall, William Pelletier, Amarat Simonne

Journal of Applied Packaging Research

Oxidation of polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in fish causes loss of product quality. Oxidative rancidity causes loss of nutritional value and undesirable color changes. Therefore, powerful antioxidant extracts may provide a relatively low cost and natural means to reduce oxidation, resulting in longer, higher quality and higher value shelf life of foods.

In this study, we measured synergistic effects of red cabbage antioxidant and vacuum packaging on lipid oxidation in fresh tilapia patties using thiobarbituric acid reactive substances (TBARS) assay, peroxide value (PV), pH and color analysis.

Concentrated red cabbage extract was obtained ...

The soybean cyst nematode (SCN), Heterodera glycines, has been a serious national problem for over three decades. Although a number of strategies for the management of SCN have been tried, a solution that is consistent with both economics and sustainable agriculture has not yet been found (Niblack et al., 1992).


Homocysteine Metabolism And Its Relation To Health And Disease., Kelly T. Williams, Buddhi P. Lamsal 2017 Iowa State University

Homocysteine Metabolism And Its Relation To Health And Disease., Kelly T. Williams, Buddhi P. Lamsal

Buddhi P. Lamsal

Homocysteine is a metabolic intermediate in methyl group metabolism that is dependent on a number of nutritional B-vitamin cofactors. An emerging aspect of homocysteine metabolism is its relation to health and disease. Perturbations of homocysteine metabolism, particularly intracellular and subsequently circulating accumulation of homocysteine (i.e., hyperhomocysteinemia), are associated with vascular disease risk, as well as other pathologies. However, intervention with B-vitamin supplementation has been shown to successfully restore normal homocysteine concentrations, but without concomitant reductions in disease risk. Thus, the mechanistic relation between homocysteine balance and disease states, as well as the value of homocysteine management, remains an area ...


Sodium Reduction In Turkey Breast Meat By Using Sodium Anion Species, Janamkumar Pandya 2017 University of Massachusetts - Amherst

Sodium Reduction In Turkey Breast Meat By Using Sodium Anion Species, Janamkumar Pandya

Masters Theses May 2014 - current

Research studies show that an average American consumes 3,400 to 4,500 mg/day of sodium in their diet against the dietary recommendation of 1,500 to 2,300 mg/day. The majority of this sodium comes from processed foods. Excess sodium in the diet can potentially cause health issues such as hypertension, heart attack, kidney failure, and bone problems. The objective of this study is to understand sodium diffusion in a protein model using turkey breast meat and determine the opportunities of its reduction by changing the process conditions and combining table salt with other sodium salts.

Since ...

The presence of nanoparticles in beverages has raised great concern in terms of potential impacts to consumer health. Herein, carbon dots in beverages kvass, pony malta, pilsner beer, Vivant Storm, and Profit were identified. They were shown to have a strong fluorescence under the excitation of ultraviolet light. The emission peaks shift to longer wavelengths accompanied by a remarkable fluorescence intensity decrease. The carbon dots are in the nanosized range and roughly spherical in appearance. Elemental analysis by X-ray photoelectron spectroscopy demonstrated the composition of Kvass carbon dots to be C 83.17%, O 13.83%, and N 3.00 ...


Edible Insects As A Source Of Food Allergens, Lee Palmer 2016 University of Nebraska-Lincoln

Edible Insects As A Source Of Food Allergens, Lee Palmer

Dissertations, Theses, & Student Research in Food Science and Technology

Increasing global population increasingly limited by resources has spurred interest in novel food sources. Insects may be an alternative food source in the near future, but consideration of insects as a food requires scrutiny due to risk of allergens. Currently, the insect Dactylopius coccus, known as cochineal, is used to produce carmine, a natural red pigment used in food, which has caused allergic reactions. This study investigated allergens of cochineal focusing on purification from the pigment. Mass spectrometry identified a previously described major allergen of cochineal and a tropomyosin, although further work is required.

Tropomyosin is a major cross-reactive allergen ...

Two different concentrations of microbial loading were used i.e.,109 and 104, cultured in nutrient media broth, strawberry shakes, and on celery sticks. Both CEOs of leaf and bark at 0.5% and 1% were found to completely ...


An Investigation Into Spent Coffee Waste As A Renewable Source Of Bioactive Compounds And Industrially Important Sugars, Damhan Scully, Amit Jaiswal, Nissreen Abu-ghannam 2016 Dublin Institute of Technology

An Investigation Into Spent Coffee Waste As A Renewable Source Of Bioactive Compounds And Industrially Important Sugars, Damhan Scully, Amit Jaiswal, Nissreen Abu-Ghannam

Articles

Conventional coffee brewing techniques generate vast quantities of spent espresso grounds (SEGs) rich in lignocellulose and valuable bioactives. These bioactive compounds can be exploited as a nutraceutical or used in a range of food products, while breakdown of lignocellulose generates metabolizable sugars that can be used for the production of various high-value products such as biofuels, amino acids and enzymes. Response surface methodology (RSM) was used to optimize the enzymatic saccharification of lignocellulose in SEGs following a hydrothermal pretreatment. A maximum reducing sugar yield was obtained at the following optimized hydrolysis conditions: 4.97 g of pretreated SEGs, 120 h ...

Tissue-Specific Alterations Of Methyl Group Metabolism With Dna Hypermethylation In The Zucker (Type 2) Diabetic Fatty Rat., Kelly T. Williams, Kevin Schalinske

Kevin Schalinske

BackgroundAltered methyl group and homocysteine metabolism were tissue-specific, persistent, and preceded hepatic DNA hypomethylation in type 1 diabetic rats. Similar metabolic perturbations have been shown in the Zucker (type 2) diabetic fatty (ZDF) rat in the pre-diabetic and early diabetic stages, but tissue specificity and potential impact on epigenetic marks are unknown, particularly during pathogenesis.

Methods ZDF (fa/fa) and lean (+/?) control rats were killed at 12 and 21 weeks of age, representing early and advanced diabetic conditions. Blood and tissues were analysed with respect to methyl group and homocysteine metabolism, including DNA methylation.

Results At 12 weeks, hepatic ...


The Impact Of Food Viscosity On Eating Rate, Subjective Appetite, Glycemic Response And Gastric Emptying Rate, Yong Zhu, Walter H. Hsu, James Hollis 2016 Iowa State University

The Impact Of Food Viscosity On Eating Rate, Subjective Appetite, Glycemic Response And Gastric Emptying Rate, Yong Zhu, Walter H. Hsu, James Hollis

James Hollis

Understanding the impact of rheological properties of food on postprandial appetite and glycemic response helps to design novel functional products. It has been shown that solid foods have a stronger satiating effect than their liquid equivalent. However, whether a subtle change in viscosity of a semi-solid food would have a similar effect on appetite is unknown. Fifteen healthy males participated in the randomized cross-over study. Each participant consumed a 1690 kJ portion of a standard viscosity (SV) and a high viscosity (HV) semi-solid meal with 1000 mg acetaminophen in two separate sessions. At regular intervals during the three hours following ...


Dietary Oil Composition Differentially Modulates Intestinal Endotoxin Transport And Postprandial Endotoxemia, Venkatesh Mani, James H. Hollis, Nicholas K. Gabler 2016 Iowa State University

Dietary Oil Composition Differentially Modulates Intestinal Endotoxin Transport And Postprandial Endotoxemia, Venkatesh Mani, James H. Hollis, Nicholas K. Gabler

James Hollis

Background: Intestinal derived endotoxin and the subsequent endotoxemia can be considered major predisposing factors for diseases such as atherosclerosis, sepsis, obesity and diabetes. Dietary fat has been shown to increase postprandial endotoxemia. Therefore, the aim of this study was to assess the effects of different dietary oils on intestinal endotoxin transport and postprandial endotoxemia using swine as a model. We hypothesized that oils rich in saturated fatty acids (SFA) would augment, while oils rich in n-3 polyunsaturated fatty acids (PUFA) would attenuate intestinal endotoxin transport and circulating concentrations. Methods: Postprandial endotoxemia was measured in twenty four pigs following a porridge ...

Suzanne Hendrich

The effects of fumonisin B-glucose reaction products in swine diets was examined. Pigs were fed diets containing 528 µmol of total fumonisin B/kg (FB), 528 µmol of total FB-glucose adducts/kg (FB-G, 122 µmol of unreacted FB/kg), or 0 µmol of total FB/kg for 15 days to test the efficacy of the FB-G reaction products in detoxifying FB. Weight gain in FB pigs was lower than in FB-G or controls, which was correlated with feed intake reduction in FB pigs. Serum aspartate aminotransferase, γ-glutamyltransferase, and total bilirubin in FB pigs were higher than in FB-G or control ...

Diane F. Birt

Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS) qualitatively and quantitatively measured resistant starch (RS) in rat cecal contents. Fisher 344 rats were fed diets of 55% (w/w, dry basis) starch for 8 weeks. Cecal contents were collected from sacrificed rats. A corn starch control was compared against three RS diets. The RS diets were high-amylose corn starch (HA7), HA7 chemically modified with octenyl succinic anhydride, and stearic-acid-complexed HA7 starch. To calibrate the FTIR-PAS analysis, samples from each diet were analyzed using an enzymatic assay. A partial least-squares cross-validation plot generated from the enzymatic assay and FTIR-PAS spectral results for starch ...
