    Creation of marshmallow with natural dyes is impossible without investigation of properties of products and estimation of its quality. Our objects of investigation were organoleptic, physico-chemical and antioxidant properties of the products at storage for 30 days. The six of marshmallow samples were the objects of our research. They differed in the type of structuring agent - gelatin or gelatin with solubilized substances and the type of dye – water or water-alcohol extract of cryopowder from Sudanese rose or water-alcohol extract of cryopowder from Π²lack chokeberry. Necessary indexes of quality are supplied for the new types of marshmallow with natural dyes. Moisture content (19.0 ... 21.5 %), total acidity (3.5 Β°Brix), density (0.51 ... 0.67 g/cm3), reducing substances content (not more than 13.6 %) were determined by standard methods. Use of natural anthocyanin dyes let us to increase antioxidant properties of the ready product. Value of antioxidant capacity of the new samples, determined with use of galvanostatic coulometry method, is in 2 ... 2.5 times more than the same results for samples, made without the dyes. It was established that short time storage (up to 2 days) of marshmallow with natural anthocyanin dyes at temperature (15...18)Β°Π‘ and relative air humidity 60...75 % is possible without packing materials. Storage of the products in hermetically polyethylene wrap and cardboard box provides high indexes of quality, stability of colour in long time (up to 30 days). It was shown that antioxidant properties of marshmallow with water-alcohol extracts of cryopowder from Sudanese rose and black chokeberry remain stable. The new developed types of marshmallow with natural anthocyanin dyes makes wide market of confectionery and can be used for correction of feeding of a man

    The polyphenol composition of grape seeds powder (GSP) and defatted grape seeds flour (DGSF) in waterΒ­alcohol (ethanol, isopropanol) extracts was studied by the chromatographic method. There was established the content of antioxidants, which are present in the form of phenolic acids (gallic, ellagic), stilbenes (resveratrol) and flavonoids, first of all, flavanols (catechin, epicatechin) and flavonols (kaemferol, myricetin, quercetin and its derivative glycosides). It was shown that the total content of polyphenols reaches a maximum size of about 4.5Β % in gallic equivalent of the powder weight at the extraction of waterΒ­ethanol mixture with ethanol content of 50Β % (w/w). The effect of phenolic antioxidants on peroxide (PV) and acid (AV) values of confectionery fats of lauric and nonΒ­lauric types in the model systems was studied as the markers of the rancidity formation process. It was proved that thanks to a high content of antioxidants in grape powders, the introduction of these powders in the composition of samples significantly slows down the process of autoΒ­oxidation of fats. It was shown that grape powders as vegetable raw material are more stable in terms of catalyzing the process of fats hydrolysis in confectionery glaze. This is evidenced by the data on the activity of lipase enzyme, the magnitude of which is lower in the samples of grape seeds powders – 1.03 and 1.12Β Γ±m3/g for GSP and DGSF, respectively, compared with that of different samples of cocoa powder – 0.84 and 1.87Β Γ±m3/g. The study into changes in acid value of the samples also showed that the addition of GSP and DGSF as the source of antioxidants significantly inhibits the process of hydrolysis of fats to free fatty acids. The obtained results have a practical significance for the improvement of the process of confectionary glaze production in the direction of partial substitution of cocoa powder with grape seeds powders. This contributes to the creation of a product with a high nutritional value and which is more resistant to damage as a result of the process of oxidation and hydrolysis of fatsΠ₯роматографичСским ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠΌ исслСдован ΠΏΠΎΠ»ΠΈΡ„Π΅Π½ΠΎΠ»ΡŒΠ½Ρ‹ΠΉ состав Π²ΠΈΠ½ΠΎΠ³Ρ€Π°Π΄Π½Ρ‹Ρ… ΠΏΠΎΡ€ΠΎΡˆΠΊΠΎΠ² grape seeds powder (GSP) ΠΈ defatted grape seeds flour (DGSF) Π² Π²ΠΎΠ΄Π½ΠΎ-спиртовых (этанол, ΠΈΠ·ΠΎΠΏΡ€ΠΎΠΏΠ°Π½ΠΎΠ») экстрактах.

    An actual problem of the development of marshmallow with natural anthocyanin dyes was solved. The object of the investigation was organoleptic, physicochemical, antioxidant properties of the products during storage for 30 days. The subject of the investigation was 6 samples of marshmallow. They differed in the type of a structuring agent gelatin or gelatin with solubilized substances and the type of a dye a water or water-alcohol extract of Sudanese rose сryopowder or water-alcohol extract of black chokeberry сryopowder.For the new types of marshmallow with natural anthocyanin dyes, the quality indexes necessary for the product were provided. Moisture content is within 19.0...21.5 %, density is 0.51...0.67 gcm3, reducing substances content does not exceed 13.6 %, total acidity is 3.5 degrees.The use of natural anthocyanin dyes allows increasing the antioxidant properties of the finished product. The value of the antioxidant capacity for all of the developed samples is 2...2.5 times more than that of the samples, made without the dyes.It was found that short-term (up to 2 days) storage of marshmallow with natural anthocyanin dyes at a temperature of (15...18)Β°C and relative air humidity of 60…75 % is possible without packaging.Storage of the products hermetically packed in polyethylene wrap and a cardboard box provides high indexes of quality, preservation of colour intensity within a long time (up to 30 days).

    Creation of marshmallow with natural dyes is impossible without investigation of properties of products and estimation of its quality. Our objects of investigation were organoleptic, physico-chemical and antioxidant properties of the products at storage for 30 days. The six of marshmallow samples were the objects of our research. They differed in the type of structuring agent - gelatin or gelatin with solubilized substances and the type of dye – water or water-alcohol extract of cryopowder from Sudanese rose or water-alcohol extract of cryopowder from Π²lack chokeberry.Necessary indexes of quality are supplied for the new types of marshmallow with natural dyes. Moisture content (19.0 ... 21.5 %), total acidity (3.5 Β°Brix), density (0.51 ... 0.67 g/cm3), reducing substances content (not more than 13.6 %) were determined by standard methods. Use of natural anthocyanin dyes let us to increase antioxidant properties of the ready product. Value of antioxidant capacity of the new samples, determined with use of galvanostatic coulometry method, is in 2 ... 2.5 times more than the same results for samples, made without the dyes.It was established that short time storage (up to 2 days) of marshmallow with natural anthocyanin dyes at temperature (15...18)Β°Π‘ and relative air humidity 60...75 % is possible without packing materials. Storage of the products in hermetically polyethylene wrap and cardboard box provides high indexes of quality, stability of colour in long time (up to 30 days). It was shown that antioxidant properties of marshmallow with water-alcohol extracts of cryopowder from Sudanese rose and black chokeberry remain stable.The new developed types of marshmallow with natural anthocyanin dyes makes wide market of confectionery and can be used for correction of feeding of a man

    Influence of Grape Seeds Powder on Preservation of Fats in Confectionary Glaze

    Full text link
    The polyphenol composition of grape seeds powder (GSP) and defatted grape seeds flour (DGSF) in waterΒ­alcohol (ethanol, isopropanol) extracts was studied by the chromatographic method. There was established the content of antioxidants, which are present in the form of phenolic acids (gallic, ellagic), stilbenes (resveratrol) and flavonoids, first of all, flavanols (catechin, epicatechin) and flavonols (kaemferol, myricetin, quercetin and its derivative glycosides). It was shown that the total content of polyphenols reaches a maximum size of about 4.5 % in gallic equivalent of the powder weight at the extraction of waterΒ­ethanol mixture with ethanol content of 50 % (w/w). The effect of phenolic antioxidants on peroxide (PV) and acid (AV) values of confectionery fats of lauric and nonΒ­lauric types in the model systems was studied as the markers of the rancidity formation process. It was proved that thanks to a high content of antioxidants in grape powders, the introduction of these powders in the composition of samples significantly slows down the process of autoΒ­oxidation of fats. It was shown that grape powders as vegetable raw material are more stable in terms of catalyzing the process of fats hydrolysis in confectionery glaze. This is evidenced by the data on the activity of lipase enzyme, the magnitude of which is lower in the samples of grape seeds powders – 1.03 and 1.12 Γ±m3/g for GSP and DGSF, respectively, compared with that of different samples of cocoa powder – 0.84 and 1.87 Γ±m3/g. The study into changes in acid value of the samples also showed that the addition of GSP and DGSF as the source of antioxidants significantly inhibits the process of hydrolysis of fats to free fatty acids. The obtained results have a practical significance for the improvement of the process of confectionary glaze production in the direction of partial substitution of cocoa powder with grape seeds powders. This contributes to the creation of a product with a high nutritional value and which is more resistant to damage as a result of the process of oxidation and hydrolysis of fat
