When calculating polycomponent dry mix formulations for the enriched soft ice cream production the following basic principles were considered: a balanced composition of the mix, the maximum biological value, as well as the organoleptic characteristics of the finished product. The main components of the polycomponent dry mix for the enriched soft ice cream production were chosen: skimmed milk powder, quail egg powder and dried vegetable fat. The application of the computer program enables to calculate the optimal composition of the polycomponent mix, amino acid composition of which is as much as possible close to that recommended by FAO/WHO. Maximum biological value is achieved with the following component ratio: skimmed milk powder – 60 ... 61%; quail egg powder – 6 ... 7%; dried vegetable fat – 6 ... 7%. Also, the amount of the dry extract of Fucus Vesiculosus algae (0.3 ± 0.02 %) introduced in the formulation of dry multicomponent mixture was established with regard to the temperature modes of soft ice cream production. The developed polycomponent dry mix provides obtaining enriched soft ice cream with increased food and biological value, high consumer properties and is intended, in particular, for soft ice cream production in the medical and health institutions, sanatoriums, recreation centers, as well as in the regions that are geographically remote from the raw sources. Keywords: Biological Value, Computer Program, Dry Mix, Fucus Vesiculosus Algae Extract, Soft Ice Cream 1. Introduction Currently, imbalance of the protein status is observed in the existing structure of population nutrition, which is expressed in short supply of complete protein. Minerals and vitamins are also deficient nutrients. Their lack in the diet often leads to various diseases. Implementation of the complex processing of raw milk according to the resource-saving technologies using proteins of various origins makes it possible to adjust maximally the composition and properties of the finished products, to *Author for correspondence obtain products with the desired level of nutritional and biological value, to adjust the functional properties of dairy systems, to release part of the dairy raw materials and reduce the cost of the finished product10,14. Among the numerous types of dairy products frozen whipped desserts are consistently in high demand owing to the excellent taste and cooling properties, high nutritional and biological value, as well as curative properties which are achieved by the ability to control the chemical composition in accordance with modern requirements of science in nutrition8. Optimization of Blend Composition of Polycomponent Dry Mix for Enriched Soft Ice Cream In view of the seasonality of milk processing problem and shortage of raw materials in the areas where dairy farming is absent, it is advisable to use dry mix as a basis for the ice cream production. This dry mix has a number of valuable properties, such as the duration of storage, rapid reconstitution and recycling, as well as ease of transportation3,6. It should be noted that the relevant line of the catering industry development is the introduction of essential micronutrients in the composition of food products, one of which is iodine. According to research data by the WHO, iodine intake with food and water is significantly reduced: actual iodine intake by adolescents and adults makes only 40 mcg per day, i.e. below the recommended level, which is 125-130 mcg per day15,16. These data were taken into account in determining the amount of the dry extract of Fucus Vesiculosus algae introduced in the dry mix for soft ice cream. 2. Materials and Methods The following ingredients were selected as the basic components for production of the polycomponent dry mix for soft ice cream: skimmed milk powder, quail egg powder and dried vegetable fat Bonigrasa 55 PA.H4,9. For scientific substantiation of the blend composition of polycomponent dry mix for soft ice cream computer program3 was developed calculating optimal protein composition formulations. When calculating polycomponent dry mix formulation for soft ice cream the following basic principles were taken into account: a balanced composition of the mix, the maximum biological value, as well as the organoleptic characteristics of the finished product. The biological value of food proteins is known to depend on the proportion of their essential amino acids. The closer this proportion to the ideal ratio recommended by FAO/ WHO, the more balanced composition of this product13. When selecting the amount of the introduced quail egg powder and skimmed milk powder a number of factors were considered. Firstly, it is the need for maximum enrichment of ice cream with proteins and minerals. Secondly, it is required to achieve a stable emulsion, providing its stability in the presence of other formulation components, increasing viscosity of the mix and ice cream overrun, maintaining the structural stability of the finished product during freezing12. It should be noted that the protein of quail egg powder is characterized by high digestibility and biological value. Analysis of the egg powder composition showed that the 2 Vol 8 (29) | November 2015 | www.indjst.org amount of essential amino acids in the quail egg powder on average is by 40% higher than their content in the widespread chicken egg powder from1. The following calculation procedure was used to develop the ice cream mix composition. At the first stage the mix components were selected, their chemical and amino acid composition was determined. Then, the optimization criteria for choosing the best combination of the mix components were calculated according to the algorithm given below7,11. Chemical composition of the components used for producing dry mix for soft ice cream is given in Table 1. Chemical analysis of skimmed milk powder, quail egg powder and Bonigrasa 55 PA.H vegetable fat showed that the components contain substantial amounts of basic minerals and vitamins that are essential to the human body. Data for calculation of biological value of soft ice cream are given in Table 2. Table 1.

Based on the values of Xj, we compute the content of the i-th essential amino acid in the mix, mg/g of protein: Ai = N ∑ Aij ⋅ X j Bj j =1 , (1) where Aij – content of the i-th essential amino acid in the mix, mg/g product, in the j-th component, with i ∈(1...8) ; where Уj – content of carbohydrates in the j-th component, mass %. Let us calculate content of fats in the mix, mass % X j ∈0...100 , %, with where ∑ j=1 Бj – protein content in the j-th component, mass %; N – number of components. Let us determine the value of amino-acid score for each essential amino acid, % Ci = Ai ∈mar Ai. ⋅100 , (2) ∑ ∆PAC , i (3) n where ∆PACi – difference of the amino-acid score of the i-th amino acid; n – amount of the essential amino acids.

Ci (9) The ‘commensurate redundancy’ factor was determined by equation: ∈mar where Ai. – content of the i-th essential amino acid corresponding to the physiologically required norm under the FAO/WHO standard, mg/g of protein. Among the obtained results we find the minimum one – Сmin, %. The difference coefficient of the amino-acid score (DCAAS) was calculated by equation: ∑ where Жj – fat content in the j-th component, mass %. The utility coefficient was calculated by equation: Xj – mass fraction of the j-th component in the mix, X j = 100 ; N j =1 N K= dc = ∑ (A − A ∈ C i i min ) Cmin . (10) Water weight m1 (in kg) required to dissolve 1 kg of dry mix was defined as in equation: m1 100 − mw − 1 , md (11) where mw – moisture content in the dry mix, mass %; md – the required dry solids weight ratio in the reconstituted dry mix, including stabilizer dry solids, %. Weight of dry mix m2 (in kg) required to produce 1 kg of ice cream is calculated as in equation: m2 1 , m1 + 1 (12) where m1 – water weight required to dissolve 1 kg of dry mix. Let us perform computations by equations 1 – 7, changing values Xj, until optimal values are found13,15. When selecting the mix component ratio, the amount of proteins is of great concern, it should range within 3.0…6.7 %. In this case the lower limit is determined by the minimum mass fraction of MSNF (milk solids nonfat) in the mix, and the higher limit is possible when introducing the milk-protein supplements (enriching agents). Theoretically increased protein mass in the ice cream should improve the mix taste and overrun, however, since Indian Journal of Science and Technology 3 Optimization of Blend Composition of Polycomponent Dry Mix for Enriched Soft Ice Cream skimmed milk powder contains a great amount of lactose, unlimited increase in MSNF may result in the increased lactose content and generate sandiness defect. Therefore the amount of skimmed milk powder, as basic raw material, should be at most 75% of the total weight of the dry mix for soft ice cream and at least 60 %, as this may cause texture defects in ice cream14. The described procedure for optimizing recipe formulations of polycomponent mix enables to form scientifically substantiated approaches to the selection of initial components and calculate their percentage in the dry mix for soft ice cream production. The formulation also includes quail egg powder ranging from 0 to 10 % of the total weight of the dry mix. The upper limit for the component introduction is determined by the organoleptic characteristics, since quail egg powder strongly pronounced flavor and aroma inherent in quail eggs, as well as such physical and chemical properties as the moisture content and acidity. The results are shown in Table 313,15. The third component of the dry mix for soft ice cream is Bonigrasa 55 PA.H dried vegetable fat containing protein, which also must be considered when determining the biological value of the mix. Since Bonigrasa 55 PA.H dried vegetable fat serves as a source of fat in the dry mix for soft ice cream, the upper limit of the component introduction, being equal to 7% of the total dry mix weight, was determined by the fat content in mass % in the finished product5,9. 3.

Based on the optimization results mass fraction of the initial components in the dry mix for soft ice cream is calculated with regard to the optimization criteria (Figure 2). Analyzing the resented diagram it can be concluded that the maximum biological value is achieved with the following component ratio2: • Skimmed milk powder – 60…61 %; • Quail egg powder – 6…7 %; • Bonigrasa 55 PA.H dried vegetable fat – 6 …7 %. The developed computer program allows calculating optimal composition of polycomponent mixes to obtain amino-acid composition, maximally close to the ideal one and producing ice cream with high consumer properties. The results calculated by the developed computer program for the component ratio in the dry mix were evaluated by the analytical method studying the amino-acid composition of the obtained dry mix. The product amino-acid balance was assessed by computational method using equations 1-12. The obtained data are given in Tables 4 and 5. It is seen from the data of Table 4 that tryptophane is a limiting essential amino acid. In this case the more balanced content of essential amino acid is observed with respect to the FAO/WHO scale: leucine, lysine, phenylalanine + tyrosine, amino-acid score of which exceeds 100 %13,15. The other values of the essential amino acids are also balanced, as the score values approximate 100%.

The production technology of the dry mix-based soft ice cream includes the following operations: component preparation, dry mix reconstitution, filtration, mix pasteurization, mix homogenization, cooling, mix maturation and freezing (Figure 3)14. Water and dry mix ratios during its reconstitution are obtained using Computational method by equations 11-12 and are presented in Table 6. The terms ‘nutritional, biological and energy’ value (calorie count) characterize the health utility of food products depending on their chemical composition and are based on the peculiarities of metabolic transformations. In this connection the soft ice cream properties were studied from the viewpoint of satisfying human need in major nutrients. To evaluate the biological value of soft ice cream the amino-acid composition was studied using the analytical method; amino-acid score, utility coefficient, commensurate redundancy coefficient, difference coefficient of amino-acid score and accordingly biological value were determined using the computational method by equations 1-10. The obtained data are given in Tables 7-8. Analysis of the amino-acid composition (Table 7) of dry mix-based soft ice cream indicates its balanceness in Indian Journal of Science and Technology 5 Optimization of Blend Composition of Polycomponent Dry Mix for Enriched Soft Ice Cream Table 5.

The product contains the most valuable for human health sulfur-containing amino acids: methionine, involved in hematopoiesis, formation of choline and phospholipids, as well as lysine playing a great role in the metabolic processes in the human body13,15. Soft ice cream is balanced according to the biological value with regard to the FAO/WHO reference protein and also has increased biological value, as the ice cream proteins contain the complete set of the essential amino acids (Table 8). To determine the amount of introduced dry extract of Fucus Vesiculosus algae in the formulation of polycomponent dry mix for soft ice cream by the analytical method, we established the influence of temperature modes of soft ice cream production on the iodine content in the finished product. In this context the iodine content in the enriched soft ice should not exceed 1/3 of the daily intake of this minor nutrient, i.e. no more than 40.0 – 43.5 g / 100 g of the product13,16. Ice cream mix in the course of the production process is subjected to high thermal stresses in the range (358 ... 368 K), and to processing at low temperatures (269 … 267 К). Table 7.

Weight of the introduced Fucus vesiculosus dry extract: 1 – 0.10 %; 2 – 0.20 %; 3 – 0.30 %; 4 - 0.40 %. During the research it was found that the temperature processing significantly influences the variation of iodine amount both in the ice cream mix, and in ice cream itself (Figure 4). When introducing Fucus vesiculosus dry extract at the amount of 0.4 % into the dry mix for soft ice cream, it was revealed that iodine content exceeded the rated one by 5.5%, and when introducing 0.2 % of dry extract the amount of this minor nutrient was insufficient. Thus, mass fraction of dry extract of Fucus Vesiculosus algae in the dry mix made 0.3 ± 0.02 %. 4. Conclusions Application of the developed computer program allows calculating the optimal composition of polycomponent mix, amino-acid composition of which is maximally close to that recommended by FAO/WHO. Maximum biological value is achieved at the following component ratio: skimmed milk powder – 60…61 %; quail egg powder – 6…7 %; dried vegetable fat – 6 …7 %.
