vanillin to give flavour of vanilla to ice cream
vanillin to modify the flavour of chocolate
anise to cover bitter medicinals
the loss of flavour due to heating while baking
the lack of the roast note in microwave cooking
ginger roots cannot be used as such to produce a beverage but must be extracted for use in soft drink
obtained from naturally occuring plant material or natural sources by biotechnological,microbiological or physical processes.
obtained by synthesis or isolated through chemical processes from a natural aromatic material and are chemically identical to a substance present in natural products
chemically synthesised, but so far have not been found to exist in nature
Herb and spices, herb --aromatic plants, such as basil,mint,oregano and thyme, spices --other highly aromatic plants:capsium(pepper), cinnamon,etc.---consist of specific parts like fruits,roots and barks., naturally occuring essential oil, e.g. eugenol,cinnamaldehyde and menthol & non-volatile constituents contribute to characteristic flavours, essential oils--prepared by steam distillation of the dried spices & contain the volatile flavour compounds, oleoresins--the solvent extracts of the spices & contain the volatile essential oil + non-volatile resinous material, ADVANTAGES OF OLEORESINS OVER CONVENTIONAL SPICES, free from physical impurities and extraneous matter- clean product, free from pathogens and microbiological contaminants-sterile product, standardized product, flexibility to develop multiple spice blends if required, uniform dispersion of spice extract provides flavoue release, concentrated form reduces storage space and bulk handling and transport requirements, the concentrated extract can be diluted to varing strengths to meet required end-use flavour, taste ,coloue,etc
Vanilla, contain vanillin, as well as other aromatic compounds which give natural vanilla it's distinctive top-notes, vanillin content of vanilla can range from 0.5 to 2.0%, the strength of vanilla is indicated by 'fold' (max:4 fold), enhance fruit flavours in may dairy and beverage application, enhances the sweetness perception of food.(bakery products), vanilla softens or round out harsh, bitter notes in most chocolate applications such as ice creams ,cakes and syrups.
flavouring that have been produced by subjecting selected raw materials to heat which result in heat-induced reactions and fat degradation.
roasted ,caramelized, bready, meaty or nutty
2 main reactions--direct caramelization of sugars and maillard reactions
savoury products:sauces,gravies,snacks,soups,ready meals and meat products
high cost--sources usually imported.The yield often low and extraction process costs must be recovered.
low intensity or impact--large quantities must be used in products
flavour variation--degree of ripeness at harvesting, changes during processing-give off-notes
flavour profile- unwanted notes or an undesirable balance to the flavour profile
distillation- obtain flavour from plant sources
extraction- obtain animal flavours,vegetables flavours
increasing overall perception of flavour
improving the quality of a flavour
making flavour nicer
delivering on the promise
"brightening the flavour"--make it more distinct,pleasant and noticeable
reinforces the character of the main flavour
improving the liking or perception of a flavour
may impart taste or flavour of a food
Monosodium Glutamate(MSG), sodium salt of glutamic acid, an amini acid present in most proteins, to enhance flavour, the glutamate must be in its free form and in its L-configuration, produced through fermentation of various substrates, including molasses and corn syrup, can be found in yeast extracts and hydrolyzed vegetable protein(HVP), pH 5.5 -8.0, may loss effectiveness high temp.
Yeast Extracts, Autolyzed yeast--yeast that has been ,in effect,self-digested., produced through the hydrolysis of peptide bonds by naturally accuring enzyme present in the edible yeast or by addition of food grade enzymes, Autolyzed yeast extract results from a process that removes the insoluble cell wall sacs and leaves a high-protein, water-soluble product. When solubility is required, a yeast extract must be used.
Hydrolyzed Plant and Vegetable Protein(HPP/HVP), HVP--consist of 40-45% salt,9-12% glutamic acid and other flavouring, manufactured by acid hydrolysis of high-protein fractions from various grains and other plant materials, more expensive and has less flavour intensity
Nucleotides, Disodium-5'-inosinate(IMP)--isolated from bonito tuna, Disodium-5'-guanylate(GMP)--isolated from shiitake mushroom broth, MSG and nucleotides often used in synergistic combinations to enhance flavours (0.2-0.3% in finished product), 50:50 blend of MSG and IMP gives 8 times more flavour-enhancing effect compared to MSG alone, susceptible to degradation at moisture levels above 60%. Major losses can result,particulary in foods high in phosphatase activity.
Maltols and ethyl maltol(sweetness petentiator), can enhance teh flavour system of sweet goods, sugar can be reduced from 5% to 15% with 15ppm maltol, ability to suppress and even eliminate undesirable acid bite and bitter notes, minimize bitter aftertaste, help contribute brown/ cooked flavour to microwave foods
