Journal of Food Science and Biotechnology

Photodynamic antimicrobial technology (PDT ),as a non-thermal physical bactericidal method,has received increasing attention due to its high efficiency,low residue,and lack of resistance induction.Natural pigments,as food-grade photosensitizers exhibit excellent optical responsiveness and biocompatibility.Studies have shown that curcumin,chlorophylls,and porphyrin-based pigments exhibit favorable photodynamic antimicrobial efficacy in various food matrices including fruits,vegetables,meat,and drinking water.The author summarizes the photodynamic antimicrobial mechanisms of representative natural pigments,and analyzes the effects of light parameters,photosensitizer concentrations,and food matrices on photodynamic antimicrobial efficacy.Furthermore,the recent progress of PDT applications in fruit and vegetable surface disinfection,drinking water sterilization,and smart packaging is reviewed,with a focus on the role of nanocarriers and composite …

Research Progress In Aflatoxin Degradation Technologies For Edible Oils, Huishuai Li, Zhenning Li, Yu Xie, Yunfeng Zou, Shaojun Li

Journal of Food Science and Biotechnology

Aflatoxin (AF),a notorious contaminant,has been a persistent challenge to the safety of edible oils.Prolonged exposure to low doses or acute consumption of high amounts of AF may induce serious health issues.Currently,no method can completely eliminate AF from edible oils.Therefore,it is crucial to explore strategies for reducing AF levels in edible oils.The measures to degrade AF from edible oils were reviewed,mainly including physical methods (such as high-temperature treatment,ray irradiation,and adsorption ),chemical methods (such as ammonia fumigation and ozone oxidation ),and biological methods (such as microbial degradation ).In addition,this paper analyzed and discussed the principles,advantages,shortcomings,and safety of various degradation methods.Furthermore,it made an …

Complex Interplay Between Facilitation And Competition In Two Invasive Fruit Pests Data, Eleanor Mccabe, Nicholas Teets Phd

Entomology Research Data

When one invasive species facilitates the invasion of another species, it can lead to invasional meltdown. However, when the two species depend on the same finite resource, facilitation and competition can occur simultaneously and impact population dynamics. Furthermore, factors like resource availability and population density could alter the balance between facilitation and competition. Drosophila suzukii and Zaprionus indianus are two invasive insect pests that infest small fruit crops. The co-localization of these species in the same fields, coupled with the fact that Z. indianus lacks a hardened ovipositor that can penetrate the skin of fruit, has led to the hypothesis …

Biophobia And Pet Ownership: Can Having A Pet Mitigate Our Fear And Aversion Towards Nature?, Alexia Barrable

The International Journal of Ecopsychology (IJE)

Biophobia, which we defined as fear, disgust, or aversion toward natural environments or organisms, has received little empirical attention when compared to biophilia, despite its implications for human and planetary wellbeing. This mixed-methods study explores the relationship between pet ownership, biophobia, and nature connectedness among 373 English- speaking adults. Quantitative findings reveal that (M = 26.4) exhibit significantly lower levels of biophobia than non-pet owners (M = 30.1; U = 5179, Z = -2.95, p = .002, R = 0.27), although no significant differences in nature connectedness were found across pet ownership (U = 7033, Z = 0.31, p = …

Bonding With Earth: Hyperbole, Metaphor, Or Fanciful Teleology?, George Conesa

The International Journal of Ecopsychology (IJE)

At a mere glance, the notion that humans could (should strive for?) bond emotionally with an entire planet, Earth, sounds hyperbolic at best and psychologically unsound at worst. For although humans might be motivated to act in ways that pass for “bonding,” perhaps assisted by intentions and sentiments to care for a whole planet, the question remains: Which notion of Earth are they really investing all their emotions in? Important to psychologists would be to inquire whether incomplete, idealized, oversimplified, or fantastic notions of “Earth,” or bonding, turn out to be transference-love-like, platonic, overidealized forms of affect, which seldom develop …
