Improving the Technique of Scrambled Desserts Using the Food Supplement “Magnetofood”

For improving the technology of scrambled dessert products, a food supplement, based on the nanopowder of oxides of two- and trivalent iron “Magnetofood” was introduced in the recipe composition. The object of the studies is base recipes: one of mousse “Cranberry” and sambuk “Apple”. For determining technological characteristics and quality parameters, conventional standard methods were used.It has been established, that introduction of the food supplement “Magnetofood” in amount 0,1 %, 0,15 %, 0,2 % of the recipe mixture mass improves consumption properties of scrambled desserts. The mean value of the organoleptic analysis increases by (1,25±0,1) points. The density also decreases by (29±1) kg/m3 for mousses, by (26±1) kg/m3 for sambuks, and scrambling duration – by ~ 3 minutes. At storing during 24 hours at h=(90±2) %, the microbial contamination of the surface of samples decreases – QMAFAnM in 10 times, yeasts – in 2 times, molds – in 2 times.It has been established, that introduction of the supplement “Magnetofood” favors the growth of the foam-creating ability in average: by (40±2) % for mousses, by (55±3) % for sambuks. The porosity increases by (14,3±0,7) % for mousses, by (12,7±0, 6) % for sambuks. The foam structure stability of scrambled desserts improves by (14±1,1) %. The food supplement “Magnetofood” also raises the effective viscosity by (32 ±1) Pa·s for mousses and by (41±2) Pa·s for sambuks and the mechanical strength of scrambled desserts in 1,23 times.The highest parameters were inherited to mousses and sambuks with supplement “Magnetofood” mass share 0,15 %.There have been experimentally substantiated scrambling technological parameters and regimes of recipe mixtures of berry-fruit mousses and sambuks, modified by the food supplement “Magnetofood”. The total scrambling duration is (14–16) minutes. The initial scrambling speed of the berry-fruit base is (2,0–2,2) s-1, at that the scrambling time is (5–6)·60s. Then the recipe mixture is scrambled at speed (3,3–3,5) s-1 during (3–4)·60s. Scrambling is finished at speed (2,0–2,2) s-1. The distinctive feature of the improved technology is premixing of the food supplement “Magnetofood” with gelatin, realized before the technological operation of soaking gelatin in cold water.The obtained experimental data may be used at developing innovative technologies of scrambled dessert products with the food supplement “Magnetofood”

Acceptance of the Methods of Decision-making: A Case Study from Software Development Companies in Ukraine and Malaysia

Any software development company encounters issues that need decision-making. At the same time, the use of reliable and proven methods of decision-making does not become a common practice in software companies worldwide. The issues here are the need for extra staff training, allocation of additional time, and inertia of the software industry. This research studies the problems of adoption of the methods of decision-making in the software development companies of Ukraine and Malaysia. The survey was conducted to evaluate software engineers' attitudes toward the use of the methods of decision-making. Research outcomes can be used to raise the level of adoption of the methods of decision-making in software companies worldwide

Cubature formula for approximate calculation of integrals of two-dimensional irregular highly oscillating functions

The paper presents a new method for the calculation of integrals of two-dimensional irregular highly oscillatory functions for the case when information about functions is given on sets of lines. Estimation of the proposed method is done for the class of differentiable function

Forming the Structure of Whipped Desserts When Introducing the Food Additive "Magnetofood" to Their Formulation

The food additive "Magnetofood", in the form of a nanopowder with particles the size of (70‒80) nm, has been designed and proposed as an improver for the structure of whipped desserts. "Magnetofood" can both independently form the structural and mechanical properties of whipped masses and influence a gel-forming agent, participating in chemical and electrostatic interactions with it. Therefore, the food additive "Magnetofood" can simultaneously influence several technological properties in the food disperse system: it can become a stabilizer, thickener, foam- and jelly-forming agents. Owing to Fe (II), nano dimensions, and the developed active surface, "Magnetofood" acquires sorption, complexing, emulsifying, moisture retaining, fat retaining, water-binding, stabilizing, structure-forming properties. That allows us to recommend "Magnetofood" as an additive with a comprehensive effect in order to form the structure of whipped desserts and to improve the quality of whipped dessert products. It has been established that introducing the additive "Magnetofood" to the samples of berry-fruit mousses and fruit-and-egg white jellies in the amount of 0.10 %, 0.15 %, 0.20 % by weight of the formulation mixture improves the structural-mechanical properties of whipped desserts. Using the additive "Magnetofood" decreases density by (29±1) kg/m3 ‒ for mousses, by (26±1) kg/m3 ‒ for fruit-and-egg white jellies, as well as the duration of whipping by ~15 % compared to control. It has been proven that introducing the additive "Magnetofood" contributes to an increase in: plastic strength ‒ by 1.23 times; porosity ‒ by (14.3±0,7) % for mousses and by (12.7±0.6) % ‒ for fruit-and-egg white jellies; foam stability by (22.5±1.1) % compared to control. In addition, a foam-forming capacity increases by (40±2) % for mousses and by (55 3) % for fruit-and-egg white jellies; effective viscosity ‒ by (4.4 0.2) % for mousses and by (4.1±0.2) % ‒ for fruit-and-egg white jellies compared to control. We have established that the rational content of the food additive "Magnetofood" equals 0.15 % of formulation composition.The obtained experimental data could be applied when developing technologies for whipped dessert products
