Белковая композитная смесь на основе морских объектов: товароведные и биокоррегирующие свойства

Разработана технология получения новых белковых композитных сухих смесей для введения в рацион питания людей с метаболическими нарушениями или входящих в группу риска. В качестве основы для получения белковых композитных смесей предложены ферментативные гидролиза-ты из пищевых тканей дальневосточных двустворчатых (гребешка приморского и спизулы сахалинской) и головоногих моллюсков (кальмара командорского и осьминога До-флейна). Включение белковых композитных смесей, обогащенных природными моноалкилглицеринами, в рацион питания людей с нарушением липидного обмена оказывало положительный эффект на липидный спектр в виде снижения уровня общего холестерина, триглицеридов и липопротеидов низкой плотности, а также индекса атерогенности. A technology has been developed for obtaining new protein composite dry mixtures for introduction into the diet of people with metabolic disorders or at-risk group. As a basis for the pro-duction of protein composition, enzymatic hydrolysates from food bivalves of the Far Eastern (Patinopecten yessoensis, Spisula sachalinensis) and cephalopod mollusks (Berryteuthis magister, Octopus dofleini) are proposed. Viscous creamy hy-drolysate was obtained for 2.2 ± 0.3 h with the following param-eters: the hydromodule –1: 1; the activity of the enzyme Prota-mex – 0.7 ± 0.3; pH 6.0 ± 0.5; temperature – 37 ± 0.3° C. The hydrolysis depth was 29.2 ± 34.6%, the viscosity of the hydrolysates was 11.3-11.8m2/s. Drying of the hydrolysates was performed by the method of freeze-drying. Dry hydrolysates from mollusks were used in the recipes of composite mixtures; their mass fraction was 67.8-69.8%. To increase the nutritional value and improve the organoleptic characteristics, food and aromatic components were introduced into the composition of composite mixtures, and to improve dietary properties - a natural 1-O-alkyl-glycerol esters. In the final composition mixtures, the content of digestible proteins was 48.9-51.0%, fat – 7.9-8.7%, carbohydrates – 19.2-21.8%, mineral substances – 7.9-9.0%. Dry protein composite mixtures were packaged in bags of polymer film materials of 20-30 g each, in which the content of mon-oalkylglycerols was 360.0-720.0 mg, which allows to satisfy the daily need of the human body for them by 36.0-72.0%. The inclusion of protein composite mixtures enriched with natural monoalkylglycerols in the diet of people with lipid metabolic disturbances had a positive effect on the lipid spectrum in the form of lowering total cholesterol, triglycerides and low-density lipoproteins, as well as atherogenic index.
