Specifically, we consider the potential effect of both the nature of information provided (i.e., whether it emphasizes the differences between GM and CRISPR technology or not) and the delivery format (i.e., text versus video) used to present content-equivalent information. In this context, we also assess consumer …

Exploring Single Cell Microbial Protein As A Sustainable Fishmeal Alternative In Yellowtail Kingfish (Seriola Lalandi) Diets: Impacts On Health And Gut Microbiome, Luke Pilmer, Lindsey Woolley, Alan Lymbery, Chinh Dam, Abigail Elizur, Md Javed Foysal, Gavin Partridge

Fisheries Research Articles

Background

With the global expansion of aquaculture and the increasing demand for fish meal, identifying appropriate and sustainable alternative protein sources for aquafeeds has become essential. Single-cell protein (SCP), derived from methanotrophic bacteria, presents a promising alternative by converting methane into protein, potentially addressing both the need for alternative protein sources and reducing industrial greenhouse gas emissions. This study aimed to evaluate the effects of different levels of SCP inclusion (0%, 25%, 50%, and 75% fish meal replacement) on the health, gene expression, and gut microbiome of yellowtail kingfish (YTK, Seriola lalandi) following a 35-day growth trial.

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

Effects Of Heat Moisture Treatment On Dietary Fiber Utilization By The Gut Microbiota, Yichen Bai

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

The present study investigates the impact of heat moisture treatment (HMT) on the utilization of dietary fibers from red lentil hulls and wheat bran and its subsequent effect on gut microbiota and short-chain fatty acid production. HMT significantly decreased the water absorption index in red lentil hulls but increased it in wheat bran. For resistant starch (RS), HMT elevated its content in red lentil hulls but diminished it in wheat bran. In terms of dietary fiber content, HMT increased soluble dietary fiber in red lentil hulls. However, carbohydrate utilization and SCFA production by gut microbiota did not significantly change after …

Microbial Transfer And Cross-Contamination In Milling Facilities And Pathogen Survival In Milled Products And Baking Mixes, Aryany Leticia Peña-Gomez

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

Wheat-based products, traditionally considered low-risk due to their low moisture content, have been involved in numerous foodborne outbreaks in recent decades. Salmonella and Shiga toxin-producing Escherichia coli (STEC) present in these products have caused significant numbers of hospitalizations and massive product recalls. The microbiological quality of flour is highly dependent on the incoming wheat, which is vulnerable to contamination from field to milling. Once pathogens are present in flour, they can survive for extended periods. Implementing strategies to mitigate the risk of pathogen contamination throughout the wheat processing chain is critical.

This study evaluated the distribution of E. coli …

Development And Validation Of Aronia Melanocarpa Berry Recipes For Home Canning: Integrating Thermal Lethality Studies, Microbiological Safety, And Antioxidant Analysis, Juan Diego Villegas Posada

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

Aronia melanocarpa, also known as chokeberry, is gaining popularity for its high antioxidant content and health benefits, including reducing oxidative stress and inhibiting cancer gene expression. However, its characteristic bitterness and astringency limit its broader appeal. Chokeberry's low pH places it in the acid foods category, making it ideal for safe home canning. An acidic environment combined with heat treatment inhibits harmful bacteria like Clostridium botulinum. Home canning preserves food by sealing it in airtight containers and heating it to destroy spoilage microorganisms.

Developing safe and palatable recipes is essential for making chokeberries suitable for home canning. A …

The Effect Of Fat Content On The Inactivation And Recovery Of Listeria Spp. In Ready-To-Eat Foods After High Pressure Processing, Yhuliana Kattalina Niño Fuerte

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

High-pressure processing (HPP) is recognized by the United States Department of Agriculture Food Safety and Inspection Service (USDA FSIS) as a post-lethality treatment to control Listeria monocytogenes in ready-to-eat (RTE) meat and poultry products. A scoping review of 603 journal articles, which ultimately was narrowed down to 16 articles, revealed that the efficacy of HPP varies with fat content. The studies demonstrated that L. monocytogenes inactivation by HPP tends to be lower in RTE meats with greater than 5% fat content, compared to products with lower than 5% fat. The wide range of HPP parameters used in these studies …
