Diversity of Transformed Agricultural Products

Vocabulary flashcards detailing raw material classifications, food transformation operations, biotechnological enzymes, microbial hazards, and biosafety controls for Master 1 Agro-Food Biotechnology.

Agricultural Product

A raw material derived from plant or animal production intended directly for consumption or for subsequent processing.

Agro-Food Transformation Chain

The sequential pathway from field to table consisting of production, harvesting/slaughter, transport, reception, sorting, preparation, processing, preservation, packaging, distribution, and consumption.

Physical Transformation

A unit operation that alters primarily the form or physical structure of an agricultural raw material, such as grinding, crushing, milling, cutting, grating, pressing, filtration, or drying.

Thermal Transformation

A processing method applying heat or temperature modification, including cooking, blanching, pasteurization, sterilization, roasting, and smoking.

Chemical Transformation

A processing alteration involving chemical reactions, such as acidification, oxidation, hydrolysis, caramelization, and Maillard reactions.

Biological Transformation

A process driven by microorganisms or enzymes, including lactic, alcoholic, acetic, and mixed fermentations, as well as maturation and ripening.

Fruit Perishability

The rapid susceptibility of fresh fruits to spoilage and degradation, caused primarily by their naturally high water content.

Cereal Fermentation

A traditional and industrial biotechnological process driven by lactic acid bacteria, yeasts, and molds that results in acidification, reduction of antinutritional factors, improved digestibility, aroma enhancement, and preservation.

Cyanogenic Compounds

Naturally occurring toxic substances found in certain cassava varieties that must be eliminated or minimized through grating, fermentation, pressing, drying, and cooking.

Meat Biological Hazards

Pathogenic bacteria that frequently contaminate raw meats and meat products, specifically Salmonella, pathogenic Escherichia coli, Staphylococcus aureus, Listeria monocytogenes, and Campylobacter.

Ovoproducts

Processed food ingredients derived from eggs, such as liquid pasteurized egg or egg powder, where Salmonella represents the primary microbiological danger.

Dairy Lactic Fermentation

The metabolic conversion of milk sugars by lactic acid bacteria into lactic acid, lowering the pH, modifying texture, generating characteristic aromas, and extending shelf life.

Fish Spoilage Factors

The rapid deterioration mechanisms characteristic of fish and fishery products, governed by endogenous enzymatic activity, high microbial proliferation, and polyunsaturated lipid oxidation.

Histamine

A chemical hazard and biogenic amine formed in certain fish species as a result of temperature abuse and bacterial enzymatic degradation of histidine.

Apicultural Products

The diverse products harvested from beekeeping, comprising honey, beeswax, propolis, pollen, and royal jelly.

Lactic Fermentation

Fermentation carried out predominantly by lactic acid bacteria to produce foods such as fermented milks and fermented cereal products.

Alcoholic Fermentation

Fermentation mediated by yeasts that converts fermentable sugars into ethanol and carbon dioxide, utilized in producing fermented beverages.

Acetic Fermentation

An oxidative fermentation performed by acetic acid bacteria that oxidizes alcohol into acetic acid to produce vinegar.

Amylases

Enzymes applied in food biotechnology to catalyze the hydrolysis of starch into shorter polysaccharides, oligosaccharides, or simple syrups.

Pectinases

Enzymes utilized in the fruit processing sector to break down pectin, thereby improving juice extraction yields and facilitating clarification.

Proteases

Enzymatic biocatalysts used in food technology to hydrolyze peptide bonds within proteins into peptides and amino acids.

Lipases

Enzymes deployed in food biotechnology to modify, hydrolyze, or synthesize lipid structures.

Lactase

The biocatalytic enzyme employed to hydrolyze milk lactose into its constituent monosaccharides, glucose and galactose.

Biological Hazards

Living organisms or their active toxins capable of causing foodborne illness, including pathogenic bacteria, viruses, parasites, molds, and microbial toxins.

Chemical Hazards

Toxic chemical substances contaminating foods, such as pesticide residues, heavy metals, mycotoxins, veterinary drug residues, and processing-induced contaminants.

Physical Hazards

Extraneous foreign bodies inadvertently present in food products, such as glass fragments, metal pieces, stones, bone splinters, and plastics.

Food Risk Multiplicative Factors

The interdependent components determining overall food risk: Raw material × Process × Temperature × Time × Moisture × Hygiene × Packaging × Storage.

HACCP

A systematic preventive approach to food safety structured in 7 steps: hazard analysis, critical control points identification, critical limits establishment, monitoring, corrective actions, verification, and documentation.

Valorization of Co-Products and By-Products

The application of agro-food biotechnology to convert agricultural wastes and processing residues into high-value resources, such as transforming fruit peels into pectin, oil cakes into feed, and hulls into biochar.
