RENNIN
AN ENZYME THAT FORMS CURDS AS PART OF ANY DAIRY FERMENTATION PRODUCT; ORIGINALLY FROM CALVES' STOMACHS, NOW PRODUCED BY MOLDS AND BACTERIA
RETORT
A DEVICE FOR COMMERCIALLY STERILIZING CANNED FOOD BY USING STEAM UNDER PRESSURE; OPERATES ON THE SAME PRINCIPLE AS AN AUTOCLAVE BUT IS MUCH LARGER
BIOCONVERSION
CHANGES IN ORGANIC MATTER BROUGHT ABOUT BY THE GROWTH OF MICROORGANISMS
CURD
THE SOLID PART OF MILK THAT SEPARATES FROM THE LIQUID (WHEY) IN THE MAKING OF CHEESE, FOR EXAMPLE
MALOLACTIC FERMENTATION
THE CONVERSION OF MALIC ACID TO LACTIC ACID BY LACTIC ACID BACTERIA
ASEPTIC PACKAGING
COMMERCIAL FOOD PRESERVATION BY FILLING STERILE CONTAINERS WITH STERILE FOOD
METHANE
THE HYDROCARBON CH4, A FLAMMABLE GAS FORMED BY THE MICROBIAL DECOMPOSITION OF ORGANIC MATTER; NATURAL GAS
MALTING
THE GERMINATION OF STARCHY GRAINS RESULTING IN GLUCOSE AND MALTOSE PRODUCTION
CONTINUOUS FLOW
AN INDUSTRIAL FERMENTATION IN WHICH CELLS ARE GROWN INDEFINITELY WITH CONTINUAL ADDITION OF NUTRIENTS AND REMOVAL OF WASTE AND PRODUCTS
CASEIN
MILK PROTEIN
12D TREATMENT
A STERILIZATION PROCESS THAT WOULD RESULT IN A DECREASE OF THE NUMBER OF CLOSTRIDIUM BOTULINUM ENDOSPORES BY 12 LOGARITHMIC CYCLES
BIOMASS
ORGANIC MATTER PRODUCED BY LIVING ORGANISMS AND MEASURED BY WEIGHT
PRIMARY PRODUCER
AN AUTOTROPHIC ORGANISM, EITHER CHEMOTROPH OR PHOTOTROPH, THAT CONVERTS CARBON DIOXIDE INTO ORGANIC COMPOUNDS
SECONDARY METABOLITE
A PRODUCT OF AN INDUSTRIAL CELL POPULATION PRODUCED AFTER THE MICROORGANISM HAS LARGELY COMPLETED ITS PERIOD OF RAPID GROWTH AND IS IN A STATIONARY PHASE OF THE GROWTH CYCLE
MALT
GERMINATED BARLEY GRAINS CONTAINING MALTOSE, GLUCOSE, AND AMYLASE
FLAT SOUR SPOILAGE
THERMOPHILIC SPOILAGE OF CANNED GOODS NOT ACCOMPANIED BY GAS PRODUCTION
TROPHOPHASE
THE PERIOD IN THE PRODUCTION CURVE OF AN INDUSTRIAL CELL POPULATION IN WHICH THE PRIMARY METABOLITES ARE FORMED; A PERIOD OF RAPID, LOGARITHMIC GROWTH
BATCH FLOW
AN INDUSTRIAL PROCESS IN WHICH CELLS ARE GROWN FOR A PERIOD OF TIME AFTER WHICH THE PRODUCT IS COLLECTED
PRIMARY METABOLITE
A PRODUCT OF AN INDUSTRIAL CELL POPULATION PRODUCED DURING THE TIME OF RAPID LOGARITHMIC GROWTH
IDIOPHASE
THE PERIOD IN THE PRODUCTION CURVE OF AN INDUSTRIAL CELL POPULATION IN WHICH SECONDARY METABOLITES ARE PRODUCED; A PERIOD OF STATIONARY GROWTH FOL OWING THE PHASE OF RAPID GROWTH
BIOREACTOR
A FERMENTATION VESSEL WITH CONTROLS FOR ENVIRONMENTAL CONDITIONS, E.G., TEMPERATURE AND pH
WHEY
THE FLUID PORTION OF MILK THAT SEPARATES FROM CURD
