In this convenience sample, 106 people answered an online questionnaire regarding folate intake and awareness among vegetarians. This was created using Google Forms and was shared via Facebook, including on various national and college vegetarian group pages. There were 44 questions. Twenty-four participants were excluded, because they reported eating fish, chicken or other meat. Final data analysis included 82 subjects. The majority of these vegetarians were females over the ...


The Conjoint Effect Of Front-Label Claims’ Surface Size And Distance-To-Center On Customers’ Visual Attention And Emotional Response, Ana Isabel Rodríguez-Escudero, Pilar Carbonell, Pablo Moreno-Albaladejo 2019 University of Valladolid

The Conjoint Effect Of Front-Label Claims’ Surface Size And Distance-To-Center On Customers’ Visual Attention And Emotional Response, Ana Isabel Rodríguez-Escudero, Pilar Carbonell, Pablo Moreno-Albaladejo

Journal of Applied Packaging Research

The research purpose is to develop a better understanding on how two claim characteristics, surface size and distance-to-center, affect customers’ attention and emotional responses.The study is based on information obtained from 42 shoppers from a retail chain in Great Britain. Visual attention is measured using an eye-tracking methodology and customers’ emotions by electrodermal activity (EDA), a common indicator of autonomic nervous system (ANS). Our research reveals that, for claims located close to the center of the label, increases in surface size compensate for the attention loss associated with moving the claim further off the center. However, for peripheral product ...

Screening Of Microbial Volatile Organic Compounds For Detection Of Disease In Cattle: Development Of Lab-Scale Method, Devin L. Maurer, Christine K. Ellis, Tyler C. Thacker, Somchai Rice, Jacek A. Koziel, Pauline Nol, Kurt C. Vercauteren

Jacek A. Koziel

The primary hurdle for diagnosis of some diseases is the long incubation required to culture and confirm the presence of bacteria. The concept of using microbial VOCs as “signature markers” could provide a faster and noninvasive diagnosis. Finding biomarkers is challenging due to the specificity required in complex matrices. The objectives of this study were to (1) build/test a lab-scale platform for screening of microbial VOCs and (2) apply it to Mycobacterium avium paratuberculosis; the vaccine strain of M. bovis Bacillus Calmette-Guérin; and M. kansasii to demonstrate detection times greater those typically required for culture. SPME-GC-MS was used for ...

Evaluation Of Volatile Metabolites Emitted In-Vivo From Cold-Hardy Grapes During Ripening Using Spme And Gc-Ms: A Proof-Of-Concept, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel 2019 Iowa State University

Evaluation Of Volatile Metabolites Emitted In-Vivo From Cold-Hardy Grapes During Ripening Using Spme And Gc-Ms: A Proof-Of-Concept, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel

Somchai Rice

In this research, we propose a novel concept for a non-destructive evaluation of volatiles emitted from ripening grapes using solid-phase microextraction (SPME). This concept is novel to both the traditional vinifera grapes and the cold-hardy cultivars. Our sample models are cold-hardy varieties in the upper Midwest for which many of the basic multiyear grape flavor and wine style data is needed. Non-destructive sampling included a use of polyvinyl fluoride (PVF) chambers temporarily enclosing and concentrating volatiles emitted by a whole cluster of grapes on a vine and a modified 2 mL glass vial for a vacuum-assisted sampling of volatiles from ...


Further Purification Of Food‐Grade Alcohol To Make A Congener‐Free Product, Lingshuang Cai, Somchai Rice, Jacek A. Koziel, William S. Jenks, Johannes van Leeuwen 2019 DuPont Crop Protection

Further Purification Of Food‐Grade Alcohol To Make A Congener‐Free Product, Lingshuang Cai, Somchai Rice, Jacek A. Koziel, William S. Jenks, Johannes Van Leeuwen

Somchai Rice

Most alcoholic beverages contain small amounts of chemicals other than ethanol, the congeners. These are byproducts of the fermentation process of the substrate. Congeners are implicated in contributing to hangover (veisalgia) symptoms and it is therefore considered expedient to remove these substances. This research compared 12 established vodka brands with a new product by GC‐MS‐olfactometry. A new vodka produced in Iowa from corn was found to be the purest while another corn‐based vodka and a potato‐based vodka contained eight and 12 impurities each. Eight other commercially available vodkas contained 15–19 impurities and three vodkas showed ...

Effects Of Harvest Time On The Aroma Of White Wines Made From Cold-Hardy Brianna And Frontenac Gris Grapes Using Headspace Solid-Phase Microextraction And Gas Chromatography-Mass Spectrometry-Olfactometry, Somchai Rice, Madina Tursumbayeva, Matthew Clark, David Greenlee, Murlidhar Dharmadhikari, Anne Fennell, Jacek A. Koziel

Somchai Rice

The Midwest wine industry has shown a marked increase in growers, hectares planted, wineries, and wine production. This growth coincides with the release of cold-hardy cultivars such as Brianna and Frontenac gris, in 2001 and 2003, respectively. These white grape varieties account for one-third of the total area grown in the state of Iowa. It is generally accepted that the wine aroma profile plays a crucial role in developing a local, sustainable brand. However, the identity of Brianna/Frontenac Gris-based wine aromas and their link to the grape berry chemistry at harvest is unknown. This study aims to preliminarily characterize ...


Biogenic Volatiles Emitted From Four Cold-Hardy Grape Cultivars During Ripening, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel 2019 Iowa State University

Biogenic Volatiles Emitted From Four Cold-Hardy Grape Cultivars During Ripening, Somchai Rice, Devin L. Maurer, Anne Fennell, Murlidhar Dharmadhikari, Jacek A. Koziel

Somchai Rice

In this research dataset, we summarize for the first time volatile organic compounds (VOCs) emitted in vivo from ripening wine grapes. We studied four cold-hardy cultivars grown in the Midwestern U.S.: St. Croix, Frontenac, Marquette, and La Crescent. These cultivars have gained popularity among local growers and winemakers, but still very little is known about their performance compared with long-established V. viniferagrapes. Volatiles were collected using two novel approaches: biogenic emissions from grape clusters on a vine and single grape berries. A third approach was headspace collection of volatiles from crushed grapes. Solid-phase microextraction (SPME) was used to collect ...

Non-Linear Behavior Of Protein And Tannin In Wine Produced By Cofermentation Of An Interspecific Hybrid (Vitis Spp.) And Vinifera Cultivar, Erin L. Norton, Gavin L. Sacks, Joey N. Talbert 2019 Iowa State University

Non-Linear Behavior Of Protein And Tannin In Wine Produced By Cofermentation Of An Interspecific Hybrid (Vitis Spp.) And Vinifera Cultivar, Erin L. Norton, Gavin L. Sacks, Joey N. Talbert

Food Science and Human Nutrition Publications

Wines produced from red interspecific hybrid grape cultivars (Vitis spp.) typically have lower tannin than wines produced from vinifera cultivars, which can be attributed to the lower concentration of tannins and higher concentration of tannin binding proteins of interspecific cultivars. Tannin in wines produced from hybrid cultivars could potentially be increased by blending hybrids with vinifera. We hypothesized that blending of grapes prior to fermentation (cofermentation) should result in final wine tannin concentrations lower than wine tannin concentrations predicted from the individual components due to protein-tannin binding, but that this effect should be absent from monovarietal wines blended post-fermentation. To ...


Seaweeds As Nutraceuticals For Health And Nutrition, Emer Shannon, Nissreen Abu-Ghannam 2019 Technological University Dublin

Seaweeds As Nutraceuticals For Health And Nutrition, Emer Shannon, Nissreen Abu-Ghannam

Articles

Throughout human history, seaweeds have been used as food, folk remedies, dyes, and as mineral-rich fertilisers. Seaweeds as nutraceuticals or functional foods with dietary benefits beyond their fundamental macronutrient content are now a major research and industrial development concept. The occurrence of dietary and lifestyle related diseases, notably type 2 diabetes, obesity, cancer, and metabolic syndrome has become a health epidemic in developed countries. Global epidemiological studies have shown that countries where seaweed is consumed on a regular basis have significantly fewer instances of obesity and dietary-related disease. This review outlines recent developments in seaweed applications for human health from ...

Bioinformatics Identification Of Anti-Crispr Loci By Using Homology, Guilt-By-Association, And Crispr Self-Targeting Spacer Approaches, Yanbin Yin, Bowen Yang, Sarah Entwistle

Faculty Publications in Food Science and Technology

Anti-CRISPR (Acr) loci/operons encode Acr proteins and Acr-associated (Aca) proteins. Forty-five Acr families have been experimentally characterized inhibiting seven subtypes of CRISPR-Cas systems. We have developed a bioinformatics pipeline to identify genomic loci containing Acr homologs and/or Aca homologs by combining three computational approaches: homology, guilt-by-association, and self-targeting spacers. Homology search found thousands of Acr homologs in bacterial and viral genomes, but most are homologous to AcrIIA7 and AcrIIA9. Investigating the gene neighborhood of these Acr homologs revealed that only a small percentage (23.0% in bacteria and 8.2% in viruses) of them have neighboring Aca homologs ...

Application Of Active And Edible Films Of Sodium Caseinate To Extend The Shelf-Life Of Argentine Pategrás Cheese, Brenda S. Álvarez, Natalia Damiani, Marina Czerner, Josefa F. Martucci, Liesel B. Gende

Journal of Applied Packaging Research

Argentine Pategrás cheese is one of the most popular types of cheese in Argentina. The main spoilage causes in these products are microbiological contamination and lipid rancidity. Semi-hard cheeses are usually covered with a paraffin wax that favors its preservation. When pieces are stored, cutting faces must be protected to prevent desiccation and contamination. Active biodegradable films are an alternative to the traditional materials, in particular, casein-based edible films are attractive for food applications. In the present work, active films of sodium caseinate with oregano (Origanum vulgare) and laurel (Laurus nobilis) essential oils were produced for packaging a processed Pategrás ...


Anti-Cancer Effects Of Oleocanthal And Extra Virgin Olive Oil, Limor Goren 2019 The Graduate Center, City University of New York

Anti-Cancer Effects Of Oleocanthal And Extra Virgin Olive Oil, Limor Goren

All Dissertations, Theses, and Capstone Projects

Oleocanthal is a phenolic compound found in varying concentrations in extra virgin olive oil. Oleocanthal has been shown to be active physiologically, benefiting several diseased states by conferring anti-inflammatory and neuroprotective benefits. Recently, we and other groups have demonstrated its specific and selective toxicity toward cancer cells; however, the mechanism leading to cancer cell death is still disputed. The current study demonstrates that oleocanthal induced damage to cancer cells’ lysosomes leading to cellular toxicity in vitro. Non-cancer cells were significantly less affected. Lysosomal membrane permeabilization following oleocanthal treatment in various cell lines was assayed via three complementary methods. Additionally, we ...


Laser-Induced Breakdown Spectroscopy (Libs): A Potential Quality Tool For Infant Formula Manufacture, Xavier Cama Moncunill 2019 Technological University Dublin

Laser-Induced Breakdown Spectroscopy (Libs): A Potential Quality Tool For Infant Formula Manufacture, Xavier Cama Moncunill

Doctoral

Breast milk is considered the ideal food for infants. However, breastfeeding is at times supplemented or replaced with suitable alternatives. Infant formula (IF) is an industrially produced food intended as a breast milk substitute, which needs to satisfy, by itself, all nutritional requirements of infants. For this reason, it is of critical importance that IF provides the adequate amounts of nutrients including carbohydrates, fats, proteins, minerals and vitamins. Laser-induced breakdown spectroscopy (LIBS) is a promising emission spectroscopic technique for elemental analysis, which can provide real-time measurements with little to no sample preparation. Hence, the main goal of this thesis was ...
