El crimen organizado transnacional ha sido nefasto para el territorio colombiano, en especial el asociado a la producción de coca en la última década, lo que ha generado impactos económicos y sociales debido al aumento del conflicto e inseguridad en las zonas de influencia del cultivo. Esto se debe a que en el 2023 se tenían 230 000 hectáreas sembradas, lo que representa el 20 % de la superficie del país, con un impacto ambiental no cuantificado en términos penales. Este requiere de acciones de entidades estatales, así como de cooperación internacional, para adaptar estrategias y poder judicializar estos delitos …

The demand for clean-label meat products has increased interest in natural alternatives to synthetic antioxidants and antimicrobials. This study evaluated the effects of buffered dry vinegar (BDV), fermented onion juice (FOJ), and their combination (CMB) on microbial stability and sensory quality of pork sausage during 9 days of refrigerated storage. Sausages were assigned to control, FOJ (0.5%), BDV (0.5%), or CMB (0.25% each) treatments. BDV and CMB significantly reduced aerobic and psychrotrophic counts by days 7-9, while yeast increased across all treatments over time, reaching ~7 Log CFU/g by day 9.

One of the main problems of our time is the sharp increase in alimentary-dependent diseases or so-called "diseases of civilization" caused by unbalanced nutrition, namely a stable deficiency or excess of nutrients with food relative to the physiological human needs. Therefore, recently there has been an increased interest in the production of functional products with a relatively balanced composition of certain nutrients depending on their purpose and intended use. A promising object of modification is traditional fat products, the transformation of which into functional ones is carried out by combining various types of raw materials, i.e., by creating composite (model) …

Highly pathogenic avian influenza (HPAI) remains a persistent threat to global poultry production and public health. Current vaccine platforms show limited cross-clade efficacy and often fail to induce mucosal immunity. Recent advances in microbiome research reveal critical roles for gut commensals in modulating vaccine-induced immunity, including enhancement of mucosal IgA production, CD8+ T-cell activation, and modulation of systemic immune responses. Engineered commensal bacteria such as Lactococcus lactis, Bacteroides ovatus, Bacillus subtilis, and Staphylococcus epidermidis have emerged as promising live vectors for antigen delivery. Postbiotic and synbiotic strategies further enhance protective efficacy through targeted modulation of the gut microbiota. Additionally, artificial …

This study evaluated the effectiveness of individual clean-in-place (CIP) steps in removing biofilms from reverse osmosis (RO) membranes under dynamic flow conditions using the Centers for Disease Control (CDC) biofilm reactor. Biofilms were developed in the laboratory under continuous flow, using mixed-species bacterial isolates obtained from 10-month-old RO membrane biofilms from a commercial facility. Individual CIP chemicals, representative of those used in commercial protocols, were tested against 24 h-old biofilms. Additionally, a complete six-step sequential CIP process was conducted under dynamic conditions, consisting of treatments with alkali, surfactant, acid, enzyme, a secondary surfactant, and sanitizer. All experiments were performed in …

Comparative Impacts Of Irradiation On Antioxidant Compounds Of Scalded And Non-Scalded Skin Of Granny Smith Apples, Angela Banda
Food Science (MS) Theses
Post-harvest Superficial scald affects the quality of Granny Smith Apples. Oxidative stress develops superficial scald with antioxidant systems mitigating the extent of this damage. This study evaluated the effects of gamma, X-ray, and electron beam irradiation on antioxidants – ascorbic acid, total phenolics, α-tocopherol, carotenoids, chlorophyll, and campesterol – in scalded and non-scalded apple peel tissue. Apples were treated with 0.2-0.77 kGy and stored at 0-1 °C. Irradiation at the applied doses increased scald incidence, suggesting that disruption of antioxidant systems promoted reactive oxygen species accumulation and membrane damage. While certain antioxidants appeared to be upregulated as a stress response, …

Low-moisture food (LMF) processing environments pose a persistent food safety risk due to Salmonella survival and harborage on surfaces. This work investigates persistent bacterial populations (PBPs) in LMF production environments, focusing on identifying a suitable surrogate and evaluating sanitation strategies. Three potential surrogates, Escherichia coli MP 26, Enterococcus faecium, and Pediococcus acidilactici, were compared to Salmonella PBPs formed in nonfat dry milk (NFDM) on stainless steel coupons stored at 25°C under 30% or 70% relative humidity (RH) using two different inoculation methods. E. faecium showed survival patterns most similar to Salmonella, with no significant differences in log reductions (p > 0.05), …

Food science provides an opportunity to engage high school students in Science, Technology, Engineering, and Mathematics (STEM) by connecting classroom concepts to real-world applications. Despite the field’s relevance to public health, food safety, sustainability, and innovation, food science remains largely absent from high school curricula, and few students recognize it as a viable STEM pathway. This research addressed this gap by evaluating immersive summer camp experiences and teacher-focused curriculum review as strategies to increase food science awareness and interest among students and educators. A literature review traced the historical development and current landscape of K–12 food science education, identifying barriers …

Cardiovascular diseases are one of the leading causes of mortality worldwide in which hypertension is a risk factor. Present pharmacological interventions require long-term adherence to the therapy and are often associated with undesirable side effects. Moreover, treatments have overlooked the role of the microbiome in the development of hypertension. Egg white hydrolysate (EWH) has exhibited antihypertensive properties with potential to be used as a natural alternative for the prevention and management of hypertension. However, EWH peptide’s effect on the gut microbiome remains yet to be elucidated. Studies have described that a portion of the ingested protein can remain undigested as …
