Food Science and Human Nutrition Publications

BACKGROUND

A significant amount of nutrients, including dietary fibers, proteins, minerals, and vitamins are present in legumes, but the presence of anti‐nutritional factors (ANFs) like phytic acid, tannins, and enzyme inhibitors impact the consumption of legume and nutrient availability. In this research, the effect of a physical process (sonication or precooking) and fermentation with Lactobacillus plantarum and Pediococcus acidilactici on ANFs of some legumes was evaluated.

RESULTS

Total phenolic contents were significantly (p<0.05) reduced for modified and fermented substrates compared to non‐fermented controls. Trypsin inhibitory activity (TIA) was reduced significantly for all substrates except for unsonicated soybean and lentil fermented with L. plantarum and P. acidilactici. When physical processing was done, there was a decrease in TIA for all the substrate. Phytic acid content decreased for physically ...


Sweet Dreams (Are Made Of This): A Review And Perspectives On Aspartic Acid Production, Holly Appleton, Kurt A. Rosentrater 2021 Iowa State University

Sweet Dreams (Are Made Of This): A Review And Perspectives On Aspartic Acid Production, Holly Appleton, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Publications

Aspartic acid, or “aspartate,” is a non-essential, four carbon amino acid produced and used by the body in two enantiomeric forms: L-aspartic acid and D-aspartic acid. The L-configuration of amino acids is the dominant form used in protein synthesis; thus, L-aspartic acid is by far the more common configuration. However, D-aspartic acid is one of only two known D-amino acids biosynthesized by eukaryotes. While L-aspartic acid is used in protein biosynthesis and neurotransmission, D-aspartic acid is associated with neurogenesis and the endocrine system. Aspartic acid production and use has been growing in recent years. The purpose of this article is ...

Articles

Efficient release of fermentable sugars from the complex biomass structure such as second-generation or third-generation feedstocks by an appropriate enzymatic hydrolysis needs a prior biomass fractionation. This process facilitates the exposure of more cellulose and hemicelluloses for enzymatic hydrolysis. This review focused on ‘green fractionation’ of biomass by applying the principles of green chemistry for bioethanol production. Besides, the recent technological achievements in applying these principles for the fractionation have been discussed. For green fractionation, energy delivery systems are referred to as microwave and ultrasound. Besides, green cellulose solvents, biomass-derived solvents, and supercritical carbon dioxide play an important role in ...


Consequences Of Gmo Labeling, Danny Santos Domingo, Jr 2020 University of Hawaiʻi at Mānoa

Consequences Of Gmo Labeling, Danny Santos Domingo, Jr

Horizons

Genetically Modified Organisms (GMOs) have been a hot topic of debate for decades. Granted, the biotechnology industry has seen opposition in many advances in terms of their ethical applications. Arguments have centered their safe incorporation into the food supply. It is difficult to honestly assess their safety since they have not been around for too long. That is why some extensively advocate for them to be labeled when incorporated into foods, to give consumers autonomy in making decisions on the foods they consume. Opponents, however, worry about public confusion, price increases and overall costs to producers, manufacturers, and consumers alike ...

Chemical Effects Of Cold Atmospheric Plasma On Food Nutrients, Juan Manuel Pérez Andrés

Doctoral

A range of nonthermal techniques have demonstrated process efficacy in ensuring food product safety, extension of shelf-life and in general a retention of key quality attributes. However, various physical, chemical and biochemical effects of nonthermal techniques on both macro and micronutrients are evident, leading to both desirable and undesirable changes in food products. It is important to outline the effects of non-thermal techniques on food chemistry and the associated degradation mechanisms with the treatment of foods. Oxidation is one of the key mechanisms responsible for undesirable effects induced by non-thermal techniques. Degradation of key macromolecules largely depends on the processing ...

Food Safety Risk In An Indoor Microgreen Cultivation System, Gina Marie Misra 2020 University of Arkansas, Fayetteville

Food Safety Risk In An Indoor Microgreen Cultivation System, Gina Marie Misra

Theses and Dissertations

Microgreens are immature sprouts of edible plants, sharing some similarities with sprouted seeds and petite leafy greens. Since they are most often grown in containers in buildings or greenhouses, they present a new area for food safety research at the intersection of the built environment and produce farming. Contamination by human pathogens has been extensively studied in other types of produce typically eaten raw, including sprouted seeds, which have been implicated in numerous outbreaks of salmonellosis over the last several decades. There is a paucity of knowledge about the microgreen sector of the fresh-cut industry; thus, it was determined that ...
