Cold Plasma Technology In Food Packaging, Kalpani Y. Perera, Jack Prendeville, Amit K. Jaiswal, Swarna Jaiswal

Articles

Cold plasma (CP) is an effective strategy to alter the limitations of biopolymer materials for food packaging applications. Biopolymers such as polysaccharides and proteins are known to be sustainable materials with excellent film-forming properties. Bio-based films can be used as an alternative to traditional plastic packaging. There are limitations to biopolymer packaging materials such as hydrophobicity, poor barrier, and thermos-mechanical properties. For this reason, biopolymers must be modified to create a packaging material with the desired applicability. CP is an effective method to enhance the functionality and interfacial features of biopolymers. It etches the film surface allowing for better adhesion …

The Philippine Agricultural Scientist

This study evaluated the safety of Bignay (Antidesma bunius (L.) Spreng cv. ‘Kalabaw’) fruits through a sub-acute oral toxicity test in male and female ICR mice. The evaluation was done through oral gavage of the aqueous fruit sample at 2,000 mg kg^-1 body weight dose for 28 d. Results showed that there were no significant changes in feed and water intake of male and female ICR mice as compared to the control groups that received distilled water (p < 0.05). Blood chemistry and hematology values for all mice groups were comparable to the controls and published values. All mice groups also had appreciable body weight gain (10.89% – 21.69%) with zero morbidity and mortality. Lastly, the gross and microscopic examination of the brain, heart, lungs, GI tract, liver, spleen, and kidneys showed normal architecture and histology, suggesting that the fruits did not induce any morphological abnormalities. Results of this study showed that Bignay (cv. ‘Kalabaw’) fruits are safe for consumption with an LD₅₀ of greater than 2,000 mg kg^-1 body weight.

Thermal Inactivation Kinetics Of Salmonella In Milk Powder As Impacted By Water Activity And Powder Type, Erika Litta Kadas

Graduate Theses and Dissertations

Historically, low-water activity (aw) foods (aw <0.65) were considered to be microbiologically safe for consumption. However, these foods have been implicated in outbreaks of pathogens such as Salmonella enterica, at a frequency that surely challenges this assumption of safety. Although usually implicated in outbreaks involving poultry and egg products, Salmonella spp. have frequently been the culprit in several outbreaks and recalls associated with low-water activity foods (LWAF) due to contamination resulting from the environment, animals, or even the employees during pre-or post-processing. One such LWAF that has been associated with Salmonella spp. outbreaks is milk powder. Milk powders are used in a variety of products ranging from infant formula to confectionary goods. With their widespread use, improving their safety is imperative. A key step in improving their safety is to thoroughly investigate preventive controls related to milk powder processing. The Food Safety Modernization Act (FSMA) established the Preventive Controls for Human Foods Rule, which mandates that processors design and establish a food safety plan outlining any potential hazards and the steps they will take to ensure those hazards do not compromise the safety of the product. Presently, the dairy industry does not have an established kill-step for milk powders post-spray drying. Spray drying may reduce some microbial populations, however, desiccation(e.g., spray drying) is not considered a kill-step. The work outlined in this thesis aims to assist our dairy industry partners in establishing their own thermal process for milk powders post-spray drying. Moisture sorption isotherms of two milk powders (nonfat dry milk: NFDM and a milk protein concentrate with 85% protein content: MPC-85) were determined and showcased that the temperatures at which the isotherms were determined (23, 40, or 60°C) significantly affected both the adsorption and desorption isotherms (p<0.0001) for each powder. Secondly, the thermal inactivation kinetics of Salmonella spp. in both powders were evaluated at two different water activities (0.20 and 0.30) and three temperatures (75, 80, and 85°C) to determine the effect of water activity on the thermal resistance of a cocktail of Salmonella spp. The D-values of Salmonella were heavily influenced by the thermal treatment temperature (p< 0.0001), but not the water activity (p >0.05). The overall findings contained within this thesis provide valuable information about the thermal inactivation kinetics of Salmonella spp. to our partners in the dairy industry so that they may implement an appropriate thermal process for their milk powders.

Applying A Material Science Approach To Improve Rice Processing Performance, Michelle Oppong Siaw

Graduate Theses and Dissertations

Rice is typically consumed as whole kernel, which makes the economic value of whole kernels twice that of brokens. Macro-structural defects such as fissures and chalkiness have been recognized to weaken kernel mechanical strength, and thereby increase breakage during milling. However, high percentages of brokens are sometimes recorded even though these defects are controlled prior to milling. It was hypothesized that rice milling characteristics are influenced by endosperm porosity from the structural arrangement of chemical components and by bran thickness and composition. Thus, this study aimed to modify chemical components by applying treatments to alter rice porosity and its associated …

Evaluating The Efficacy Of Germination And Fermentation In Producing Biologically Active Peptides From Pulses, Ashley Newton

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

Recently, there has been a profound increase in demand of plant-based proteins, especially pulse proteins. However, pulses contain high concentrations of antinutritional factors that hinder the digestibility of proteins. Processing techniques such as enzymatic hydrolysis, microbial fermentation, and physical processing modulate nutritional quality and functionality of pulses. Processing also releases peptides from parent proteins that exhibit health-beneficial bioactivity against various disease risk factors. In this study, germination, gastrointestinal digestion, and microbial fermentation were evaluated to determine the nutritional quality and release of bioactive peptides during and after processing.

Evaluation Of Extended Aging Type And Cooking Practices On Palatability Of Beef Steaks, Katharine Anne Bugenhagen

Graduate Theses and Dissertations

Two studies were conducted to determine if sous vide was a viable way to improve palatability of various beef cuts, and to determine whether extended aging duration and the presence of a bone impacts the consumer ratings of beef short loins.When evaluating the impact of sous vide cooking (SVG) on multiple beef muscles, there was a muscle × method interaction for overall liking (P = 0.04). The traditionally cooked (TRAD) Longisimus lumborum (LL) was rated the highest (P < 0.05). The Chuckeye steak (CHE) was rated next, both TRAD and SVG, with the traditional ranked higher, this was followed by the Triceps brachii (TB) also for both TRAD and SVG, however for the TB the SVG ranked higher (P < 0.05). The TRAD Biceps femoris (BF) rated the lowest (P < 0.05) of all of the muscles. Shear force did no differ between the cooking treatments (P > 0.05), or was there an interaction between muscle × method for shear force measurements (P < 0.05). The LL was rated the highest for tenderness (P < 0.05) while the BF was rated the lowest (P < 0.05). The second study compared subprimals aged over three aging periods (21, 42 63 days), then split into bone-in or boneless steaks, there were no interactions observed within the consumer data (P ≥ 0.05). BI steaks were rated higher (P < 0.05) for juiciness and overall liking by consumers, however BI and BL were rated similarly by consumers for tenderness and flavor (P > 0.05). When evaluated by consumers, aging did …

Cross-Modal Associations Between Hand-Feel Touch And Oral Irritation, Ragita Cantika Pramudya

Graduate Theses and Dissertations

Hand-feel touch cues have been shown to influence the perception of other sensory modalities and can be used as means to create expectations toward food or beverage products presented concurrently with such cues. However, to date, there has been limited research on how these hand-feel touch cues could impact oral irritation elicited by capsaicin-containing products. Because oral irritation sensation is a dynamic perception lasting a period of time, temporal methodologies, such as Time-Intensity (TI) and Temporal-Check-All-That-Apply (TCATA), must be used when evaluating capsaicin-containing products. The use of temporal methodologies when examining the cross-modal effects of other cues on capsaicin irritation …

Maturity Stage At Harvest Influences Antioxidant Phytochemicals And Antibacterial Activity Of Jujube Fruit (Ziziphus Mauritiana Lamk. And Ziziphus Spina-Christi L.), Adhbah R. H. Aldhanhani, Zienab F. R. Ahmed, Nikolaos Tzortzakis, Zora Singh

Research outputs 2022 to 2026

Fruits of the genus Ziziphus are known for their medicinal and nutritional value. Thus, this study aimed to investigate the influence of different maturity stages (unripe, half-ripe, and ripe fruit) at harvest on the physicochemical characteristics, phytochemical composition, antioxidants, and antibacterial activities of Ziziphus mauritiana and Ziziphus spina-christi fruits. In both plant species, the unripe fruits had significantly higher (P < 0.05) phenolic and flavonoid content and antioxidant and antibacterial activity compared with ripe fruits. At all maturity stages, these features were significantly higher (P < 0.05) in Z. spina-christi fruits than in Z. mauritiana fruits. Regardless of the species, 13 phenolic compounds were identified and quantified in the fruit extracts. For both species, the concentration of individual phenolic compounds changed with fruit maturity. Among the phenolic compounds, the gallic acid, 4-hydroxybenzoic acid, salicylic acid, catechin, and rutin levels were significantly higher (P < 0.05) in Z. spina-christi fruits than those for Z. mauritiana fruits, whereas vanillic acid and quercetin showed the opposite trend. Additionally, trans-cinnamic acid was only detected in Z. spina-christi fruits. In conclusion, the mature unripe jujube fruit, especially in Z. spina-christi, was shown to be a promising source of various naturally occurring compounds of significant interest owing to its pharmacological and therapeutic properties as an antioxidant, anti-inflammatory, and analgesic.
