Annotation Of Hypothetical Genes In Lactococcus Lactis Ssp. Il403, Jennifer A. Tangires
Annotation Of Hypothetical Genes In Lactococcus Lactis Ssp. Il403, Jennifer A. Tangires
Student Scholar Showcase
The human gastrointestinal tract (GIT) harnesses various microbial organisms involved in almost all processes of physiological homeostasis, among these are lactic acid bacteria (LAB). These bacteria, almost all of which belong to the order Lactobacillales, are able to produce lactic acid, and play an important role in food preservation because they produce bacteriocins. Bacteriocins are antimicrobial proteins that are used to fight off related bacteria in their environment that are competing for the same resources. This study focuses on a specific LAB strain, Lactococcus lactis ssp. IL1403 where 21.9% of its predicted genes have not yet been assigned a function. …

Online Class-Incremental Learning For Real-World Food Image Classification, Siddeshwar Raghavan, Jiangpeng He, Fengqing Zhu
Graduate Industrial Research Symposium
Food image classification is essential for monitoring health and tracking dietary in image-based dietary assessment methods. However, conventional systems often rely on static datasets with fixed classes and uniform distribution. In contrast, real-world food consumption patterns, shaped by cultural, economic, and personal influences, involve dynamic and evolving data. Thus, it requires the classification system to cope with continuously evolving data. Online Class Incremental Learning (OCIL) addresses the challenge of learning continuously from a single-pass data stream while adapting to the new knowledge and reducing catastrophic forgetting. Experience Replay (ER) based OCIL methods store a small portion of previous data and …

Nucleic Acid Detection Of Live Pathogens On Contaminated Foods, Simerdeep Kaur, Mohit Verma
Graduate Industrial Research Symposium
The goal is to develop a point-of-care biosensor for the detection of live pathogens contaminating beef products. Biosensing of live pathogens is based on isothermal amplification of nucleic acid on a paper-based device. A colorimetric dye is employed as an indicator of the amplification product for visual result. The assay incorporates a compound Propidium monoazide (PMA) that makes the DNA from dead cells inaccessible for amplification. This approach is especially applicable for pathogens that can enter a viable but non-culturable state (VBNC).

Application Of Fructans-Degrading Lachancea Fermentati Fst5.1 As An Alternative To Baker’S Yeast In The Production Of A Low-Fodmap Whole Wheat Bread., Małgorzata Borowska
ORBioM (Open Research BioSciences Meeting)
FODMAPs are a group of poorly absorbed dietary carbohydrates comprised of easily fermentable oligo-, di-, monosaccharides and polyols. When consumed, they can exert gastrointestinal symptoms of pain, flatulence, or an irregular bowel movement in individuals with irritable bowel syndrome. Whole wheat bread is an excellent source of proteins, vitamins, polyphenols, and other nutrients, but its consumption is restricted in a low-FODMAP diet due to high fructans content. Although alternatives exist, these are primarily gluten-free, often inferior in terms of quality, nutritional profile, and consumer acceptance. Bioprocessing using microbial fermentation has a proven capacity to reduce FODMAPs in cereal products, but …
Evaluating 3d Printing As A Technology For Producing Dairy Snacks Based On Temperature-Controlled Rennet Induced Gelation Of Protein-Fortified Milk., Ricardo Uribe Alvarez
Evaluating 3d Printing As A Technology For Producing Dairy Snacks Based On Temperature-Controlled Rennet Induced Gelation Of Protein-Fortified Milk., Ricardo Uribe Alvarez
ORBioM (Open Research BioSciences Meeting)
3D food printing (3DFP) has the potential to develop products with complex structures, personalised nutrition, and customised textures. However, only foods with suitable physicochemical or rheological properties are suitable for 3DFP to ensure a self-supported structure is printed. Milk proteins can form structured objects (i.e., cheese, yoghurt), and so are potential ingredients for 3DFP. This study aims to adapt the rennet gelation from the curdling process of cheese-making to produce 3D printed dairy snacks using milk protein isolate-fortified milk. It is well known that curdling of milk by rennet is temperature dependant; therefore, the rennet gelation properties (G' and G'') …

Bacteriophages Infecting Enterobacter Cloacae To Reduce Bloater Damage In Fermented Cucumbers
Bacteriophages Infecting Enterobacter Cloacae To Reduce Bloater Damage In Fermented Cucumbers
Symposium of Student Scholars
Fermented cucumbers are one of the most important fermented vegetables consumed worldwide. During cucumber fermentations, certain undesirable changes may occur. One of such changes is known as bloater defect (hollow cavities in fermented cucumbers), which is primarily caused by gas-producing bacteria including Enterobacter cloacae. Bloater defect lowers product quality and leads to significant economic loss to the pickle industry, and effective preventative methods are needed. Bacteriophages (phages) are highly host-specific bacterial killers. Use of phages to control unwanted bacteria in foods is a promising approach because phages do not change food properties. This research was to isolate, characterize, and …

Abstract
Cucumber fermentation is one of the most important vegetable fermentations in the United States and Europe. Enterobacter cloacae and other gas-producing bacteria can cause bloater defect (the gas pockets or hollow cavities formed in fermented cucumbers) which lowers the quality and the yield of fermented cucumbers, thereby resulting in significant economic losses to the pickling industry. Cost-effective strategies to control E. cloacae and other microbiota need to be …
The Chemistry Of Fermentation As It Relates To The Art Of Winemaking, Olivia Cochran
The Chemistry Of Fermentation As It Relates To The Art Of Winemaking, Olivia Cochran
Symposium of Student Scholars
The process of fermentation can be traced back to the beginning of civilization. Countries, over time, have learned this scientific process and turned it into the backbone of their culture through the making and manufacturing of wine. While climate-change and global-warming have impacted the commercial marketability of wine, the scientific process has remained constant. This undergraduate project analyses the production, fermentation and analytical approach of producing high quality wine. Beginning from the picking of grapes, to testing the acidity through a series of titrations, winemaking is truly where science and art collide.

Restoration Through Regeneration: An Analysis Of Agriculture In The United States, Rebecca Norine Graham
Capstone Showcase
The industrialization of agriculture in the mid-twentieth century has revolutionized global food systems, with enough food produced annually to sustain 10 billion people on a planet of only 7.8 billion people. Such a high-yielding agricultural system comes at a great cost to the Earth’s ecosystem, as industrialized farming has taken on factory-like production methods. Particularly harmful is the livestock sector, with ruminating animals such as cattle contributing to rising global temperatures and environmental degradation. The environmental destruction caused by industrialized animal agriculture can be halted and ultimately reversed through regenerative agriculture. Regenerative agriculture is a restorative farming practice that promotes …
