STALING STABILITY OF BAKERY PRODUCTS ENRICHED WITH MILK PROTEINS
Yu.M. Tkachuk, A.V. Havrysh, A.V. Nemirich, T.I. Ishchenko, V.F. Dotsenko
Staling stability of bakery products made of first grade wheat flour with the use of milk proteins - casein and albumin in combination with surface-active substances was studied. Swelling ability of crumb was investigated. Tracer method was used to study the amount of bound water. Moisture state was investigated by nuclear magnetic resonance method. Nature of changes of the intensity of the reflected radiation in the structure of starch grains of breadcrumb during storage was also considered. Moisture in bakery products made with milk proteins and surface-active substances is found to get bound and retained mostly during storage than in the sample items. There was determined the mechanism of the interaction of surface-active substances with starch polysaccharides, which causes slowing down of amylose and amylopectin retrogradation, thus resulting in increasing shelf life of new products.

DETERMINATION OF LACTOSE IN HYDROLYSED MILK MIXTURES BY MODIFIED IODOMETRICMETHOD
T.L. Shulуak, M.A. Glushakov
A modified iodometric method for the determination of lactose in hydrolyzed milk mixtures was developed. Formulas for calculation of mass fraction of residual lactose and those for calculation of the degree of hydrolysis of lactose in milk mixtures with regard to the iodometric method were obtained. The proposed formulas can be used in the analyses of low-lactose milk mixtures containing any dry skimmed milk residue at any stage of the technological process. |

COLOUR REGULATION COMPOSITIONSFOR HIGH-YIELD MEAT PRODUCTS
S.V. Ivanov, I.I. Kishenko, Yu.P. Kryzhova,A.P.Donets
A study was made in colour formation compositions with an intensive red-pink range that are capable to provide products with a characteristic colour for high-yield meat products irrespective of the quantitative content of raw material products without myoglobine. The mechanism for formation of color characteristics of experimental meat product systems with low content of myoglobine in the stage of salt curing with addition of multifunctional brine colloidal systems of nitrite salt (instead of sodium nitrite) and natural coloring agents (Аprо Red and Vepro 70 Col Р (Viady,Holland)was investigated.

DETERMINATION OF WASHING-OUT WATER FLOW VELOCITIES IN WASHING MACHINES FOR ROOT CROPS
A.N. Vsevolodov
The analysis of contaminants of edible vegetative raw materials carried out in this article has revealed that soil contaminants are the main reason for the contamination of raw materials. Possible quantity of contaminants in average size raw materials is defined. The obtained experimental data have determined the degree of humidity of soil contaminants at which they get fluid. Expediency of "dry washing» technological process is proven in order to reduce considerably consumption of clean water during washing. The experiment aimed at determining water speeds in a washing machine for washing out the contaminants remained after "dry washing» is described. The recommended scheme for the construction of a two-level drum-type washing machine for root crops results from experimental findings. It is proved that "dry washing» processes combined with the traditional instruments of contaminant removal from outer layer of vegetative raw materials and well-coordinated modes of washing when a two-level method is applied make possible to reduce substantially consumption of pure flowing drinking water and secure high parameters of washing quality.

The level of automation of the machinery for polymer films production was considered. Deformation process in polymer film was analyzed and a mathematical model for the dynamics of motion of polymer film in polymeric film materials installation was developed. Deformation process of the material in the area between sections specified by its tension is found to depend on the relationship of linear velocities of the sections and tension values in the areas.
