Effects of protein and carbohydrate ingredients on colour of baked milk products
(2024) Mandiuk, Olena; Lohinova, Anna; Arsenieva, Larisa; Petrusha, Oksana; Polishchuk, Galyna
In the CIE Lab system, only the coordinates “a” and “b” should be used to characterize the color change of milk of 2.5% fat and cream of 10% fat during heat treatment at 95–97 ⁰C for 160–180 min, as the L indicator (light level) is not sufficiently informative. According to the selected coordinates, rational ranges were established as a criterion for the completeness of the Maillard reaction for baked milk and cream, in particular for coordinate “a” in the range from 1.5 to 2.0 units, for coordinate “b” from 11.5 to 13.0 units. The application of whey protein concentrate, hydrolysed demineralized whey concentrate, and glucose-fructose syrup, which contain monosaccharides and proteins, significantly enhanced the Maillard reaction. The recommended values for color coordinates of cream with milk protein and carbohydrate ingredients were achieved during the simmering process. For cream with whey protein concentrate, this occurs at a minimum of 21 min; for cream with hydrolysed whey concentrate at a minimum of 28 min, and for cream with glucose-fructose syrup and whey protein concentrate at a minimum of 18 min. The samples with whey protein concentrate and glucose-fructose syrup, including those one with whey protein concentrate, showed an excellent level of quality in terms of sensory characteristics after 20 min, while the sample with hydrolysed whey concentrate demonstrated this after 30 min of simmering. These results correlated with the rational duration of cream simmering to achieve the recommended degree of color. A slight decrease in acidity was observed in all cream samples during the heating process. The reduction in the duration of the simmering process of dairy products with simultaneous achievement of recommended color characteristics will contribute to a significant reduction in heat energy consumption

Наведено методику збагачення масляної пасти суміші природних мікроелементів насіння білого кунжуту та порошків з моркви та помідорів, одержаних шляхом сушіння холодним розпиленням у кількості 2%, 8% та 4% відповідно. На підставі аналізу мікроструктур вивчено структурні елементи, які утворювали компоненти рослин з жирною та водною фазами солоної масляної пасти, а також визначали розмір і розподіл крапель плазми. Методом мікроструктурного аналізу встановлено взаємодію компонентів рослинної сировини з жировою та водними фазами та масляною суміші, виявлено формування структури агломераційної сітки. Дослідження кристалізації жирової фази визначали за допомогою диференціальної скануючої калориметрії. Ці результати вказують на те, що є компоненти рослинної сировини, які змінюють кристалізацію жирової фази продукту. The paper presents a method of enriching buter paste complex natural mixture of micronutrients by a slurry of white sesame seeds and powders from carrot and tomatoes obtained by cold spray drying, in amounts of 2%, 8% and 4% respectively. On the basis of microstructure analysis, we studied the structural elements that formed plant components with the fat and aqueous phases salt butter paste, as well as we determined the size and distribution of droplets characterized by plasma product. The method of microstructure analysis of the interacting components of vegetable raw materials with fatty and aqueous phases and oil mixture revealed the formation of sinter mesh structure. The investigation of crystallization of fat phase was determined by differential scanning calorimetry. These results indicate that there are components of plant raw materials which alter crystallization of the fat phase of the product.

Питання зберігання цукрових буряків є важливою складовою для отримання якісного, максимального виходу кристалічного цукру. Оскільки цукровий буряк є рослинною із живими клітинами які в процесі зберігання реалізують життєдіяльність. У процесі дихання клітини можуть споживати цукрозу знижуючи ефективність виробництва. Клітини цукрового буряка можуть вмирати змінюючи структурні характеристики буряка. Ці всі фактори впливають на виробництво цукру.

The processes of structure formation in emulsion-type sauces using phyto- and oil carotene containing semi-finished product - a mixture fine powders of spicy-aromatic and carotene containing raw materials and oil in the environment. The prospect of using the technology developed semi low-calorie sauces emulsion type is the manifestation of surface-active properties of said plant material. Structural and mechanical properties of the finished sauce was studied using a rheometer AR 2000ex. Forms of communication research in water samples sauces determined on derivatograph Q -1500D. Emulsifying properties of powders spicy-aromatic and carotene containing materials described by phase inversion points. Drawing graphs and statistical data processing was performed using the software package OriginLab Corporation and spreadsheet Microsoft Office Excel. Due to the content of polysaccharides and essential oils, crushed and dried raw of spicy-aromatic and carotene containing able to create stable colloidal systems - emulsion type oil in water. Research emulsifying ability and fine powders of spicy-aromatic and carotene containing raw materials in emulsion oil in water showed that the emulsifying ability parsley powder is 16% and 36%, which is higher than the powder with dill and carotene containing raw materials respectively. A determination of rheological properties depending on the concentration sauces phyto- and oil carotene containing semi-finished product. Ready sauce with a mass fraction phyto- and oil carotene containing semi-finished product 30% shear rate of 200 s-1 has an effective viscosity in the range of 22-50 Pa • s, which is optimal for the type of emulsion sauces. Value Relations moisture in the form of emulsion-type sauces approaching the optimal concentration phyto- and oil carotene containing semi-finished product 30% by weight of the sauce. Thus there is a stronger binding moisture promotes aggregative stability system prevents their separation.Sauces emulsion type, made on the basis of the developed intermediate product, have optimal rheological parameters. Thus, we can recommend phyto- and oil carotene containing semi-finished product for sauces emulsion type of high nutritional value without the use of additional emulsifiers, structure-synthetic nature.
