Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy and thus plays a vital role in maintaining economic stability throughout the state. This report 1) compares the relative size of the Agriculture and Food Sector in Arkansas with …

Identifying Consumer Perceptions Of Fresh-Market Blackberries, Aubrey Dunteman

Food Science Undergraduate Honors Theses

Blackberries are grown worldwide for commercial fresh markets, but there is limited information on consumer perceptions of this fruit. In this study, physiochemical and consumer sensory attributes of three Arkansas-grown fresh-market blackberry genotypes were evaluated and consumer perceptions of fresh-market blackberries were also investigated though an online survey. Two cultivars (Natchez and Ouachita) and one advanced selection (A-2418) were evaluated for compositional and nutraceutical analysis and consumer sensory analysis. Natchez had the highest berry weight, length, drupelets and pyrenes/berry, and pyrene weight/berry. Ouachita had the highest soluble solids content (11.9%), pH (3.18) and soluble solids/titratable acidity ratio (10.92). There were …

Anti-Inflammatory Activity Of Phenolic And Volatile Compounds In Cranberries (Vaccinium Macrocarpon L), Katherine Moore

Graduate Theses and Dissertations

The primary objective of this study was to compare the anti-inflammatory effects of phenolic and volatile compounds extracted from cranberries. The Griess Reagent System assay was used to measure the in vitro anti-inflammatory capabilities of cranberry phenolic and volatile extracts on RAW 264.7 mouse macrophage cells. This study tested the anti-inflammatory capabilities of the cranberry phenolic and volatile extracts before, as a preventative treatment, and after, as a means of treating pre-existing inflammation, inducing inflammation with lipopolysaccharide (LPS). All experiments were conducted in the following manner, varying only in whether treated with the extracts before or after LPS: 1 x …

Anti-Inflammatory Effect Of Berry Essences, Inah Gu

Graduate Theses and Dissertations

Inflammation is one of defense reactions of our body tissues against harmful stimuli such as infection and tissue injury. However, it has been reported that chronic inflammation can lead to chronic inflammatory diseases including diabetes, cardiovascular diseases and cancer. This transition from acute to chronic inflammation state is usually induced by pro-inflammatory mediators and cytokines including nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), which accelerate the development of other chronic diseases. Accordingly, targeting these pro-inflammatory factors is one of the important roles for anti-inflammatory agents. For last two decades, researches about anti-inflammatory …

Evaluating Consumer Sensory And Composition Attributes Of Arkansas-Grown Fresh-Market Blackberries, Aubrey N. Dunteman, Renee T. Threlfall, John R. Clark, Margaret L. Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Blackberries are grown worldwide for commercial fresh markets. Three Arkansas-grown fresh-market blackberry genotypes (‘Natchez’, ‘Ouachita’, and A-2418) were evaluated for consumer sensory and compositional attributes at the University of Arkansas Food Science Department, Fayetteville. The compositional attributes of the blackberries were within an acceptable range for commercial markets (soluble solids=8.20-11.90%, pH=2.79-3.18, titratable acidity=1.09-1.32%). In terms of soluble solids to titratable acidity ratio, ‘Ouachita’ (10.92) had the highest ratio, followed by ‘Natchez’ (8.93) and A-2418 (6.25). A consumer sensory panel (n=80) evaluated fresh-market blackberry attributes using a 9-point hedonic scale for overall impression, overall flavor, sweetness, and sourness and a 5-point …

Effects Of Chemical And Enzymatic Modifications On Starch And Naringenin Complexation, Ana Isabel Gonzalez Conde

Graduate Theses and Dissertations

Naringenin is a flavanone naturally present in grapefruit and tomato skin, which has been demonstrated to have health benefits. However, because of the low water solubility and bioavailability, naringenin applications are limited. Starch inclusion complexes have been shown to improve the solubility and bioavailability of poorly water soluble bioactive compounds. The present study aimed to prepare and characterize complexes of naringenin with starches, including potato starch and high amylose corn starch (Hylon VII), which were chemically (acetylation or hydroxypropylation) and enzymatically modified (debranched or debrahced/β-amylase treated). Soluble and insoluble complexes were recovered, and their physicochemical properties were characterized. The treatments …

Comparative Evaluation Of The Effect Of Methyl Bromide Fumigation And Phytosanitary Irradiation On The Quality Of Fresh Strawberries, Tamar Serapian, Anuradha Prakash

Food Science Faculty Articles and Research

Fresh strawberries are highly perishable and have a short shelf-life especially when the cold chain is not maintained. Strawberries exported to Asia are currently fumigated with methyl bromide for phytosanitary purposes, which exposes strawberries to warm temperatures for several hours and air freight without temperature control, resulting in a shelf life of just a few days in the destination country. Irradiation offers an efficacious alternative to fumigation and can be performed on cold fruit. This study was conducted to compare the quality of strawberries subject to methyl bromide fumigation or irradiation followed by simulated commercial air freight shipment of strawberries …

Mangiferin As A Biomarker For Mango Anthracnose Resistance, Herma Pierre

FIU Electronic Theses and Dissertations

Mangos (Mangifera indica L.) are tropical/subtropical fruits belonging to the plant family Anacardiaceae. Anthracnose is the most deleterious disease of mango both in the field and during postharvest handling. It is most commonly caused by the Colletotrichum gloeosporioides complex. Mangiferin, a xanthanoid compound found in at least twelve plant families worldwide (Luo et al., 2012), is present in large amounts of the leaves and edible mangos. Even though this compound plays a pivotal role in the plant’s defense against biotic and abiotic stressors, no correlations been made between the compound and mango anthracnose resistance.

Mangos were collected, grouped …

Strawberry Growth, Yield, Fruit Nutrition, And Control Of Verticillium Wilt With Pre-Plant Soil Fumigants, Ozone, And Biological Control, Justin J. Scurich

Master's Theses

Verticillium wilt is a widespread soilborne disease of strawberry historically controlled by soil fumigation with methyl bromide (MB). MB was banned by the United Nations in 1995 and will be completely phased out by 2015. Research has concentrated on alternative methods of disease control without finding a single alternative able to replace MB in widespread disease control and yield increase. For the current study, strawberries were greenhouse grown in container pots filled with soil from both infested and non-infested areas of a commercial strawberry field in Watsonville, CA. Treatments included pre-plant soil fumigation with commercially available formulations of methyl bromide, …
