Food hygiene, microbiological control, additives, and safety standards.
Economically Motivated Adulteration (EMA), commonly designated as Food Fraud, involves deliberate dilution, mislabeling, or substitution of premium food matrices with inferior ingredients to maximize illicit profit. Representing an annual global economic penalty exceeding 40 billion, food fraud constitutes a direct…
Across chilled Ready-to-Eat (RTE) manufacturing sectors, Listeria monocytogenes represents the foremost biological pathogen of concern. Possessing psychrotrophic adaptability facilitating proliferation down to commercial refrigeration coordinates (4°C), alongside wide pH (4.4 – 9.4) and osmotic tolerances (> 10% NaCl), this pathogen…
While packaging systems safeguard foods against microbiological and physical vectors, mass transfer across the polymer interface into food constitutes a pervasive chemical safety risk. Known as “chemical migration” from Food Contact Materials (FCM), volatile and non-volatile plasticizers, monomers, and perfluorinated…
Food allergies stem from abnormal immunoglobulin E (IgE)-mediated or cell-mediated immune hypersensitivity responses against specific dietary proteins. Ingesting milligram quantities can induce acute, life-threatening anaphylaxis. Consequently, industrial allergen control transcends indiscriminate precautionary allergen labelling (“may contain traces”), demanding rigorous sanitary…
Beyond bacterial and viral contamination, low-molecular-weight fungal secondary metabolites present a persistent chemical safety threat across agronomic food chains. Synthesized under unmitigated post-harvest storage humidity (a_w > 0.70, T > 20°C) by Aspergillus, Penicillium, and Fusarium species, mycotoxins—predominantly Aflatoxins, Ochratoxin…
During proteolytic ripening in fermented meats, aged cheeses, wines, and scombroid fish, liberated free amino acids undergo substrate decarboxylation catalyzed by microbial enzymes, synthesizing low-molecular-weight nitrogenous bases termed biogenic amines. While trace levels participate in normal mammalian neurotransmission, acute ingestion…
In canning and aseptic food engineering, microbial lethality is governed by the thermodynamics of irreversible heat-induced denaturation of functional cellular enzymes, structural proteins, and endospore peptidoglycan coats. Insufficient thermal processing risks catastrophic botulinum toxin synthesis; conversely, excessive thermal dwell induces…
The primary paradigm shift within food processing engineering entails moving away from retrospective end-product microbiological testing toward proactive, preventative systems. Established by NASA, the Natick Laboratories, and the Pillsbury Company in the 1960s to ensure zero microbiological defect in spaceflight…
