Abstract
The article describes a technique for optimizing recipe formulations of polycomponent dry mix to produce enriched soft
ice cream, which allows generating science-based approaches to the selection of the initial components and calculating
their percentage. 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.

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

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.

of ice cream is calculated as in equation:

where m1 – water weight required to dissolve 1 kg of dry

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

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.

tion are introduced in the appropriate windows of the
computer program to determine the biological value of
the product (Figure 1).
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%.

When analyzing the data of Table 4 and 5 it can be
concluded that in terms of biological value the dry mix
for soft ice cream is balanced with regard to the FAO/
WHO reference protein and soft ice cream on the basis
of the dry mix will also have increased biological value,
since the dry mix proteins contain the complete set of the
essential amino acids.
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

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).

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 %. Also we determined
the amount of the dry extract of Fucus vesiculosus algae
is (0.3 ± 0.02 %) introduced into the polycomponent dry
mix formulation with regard to the temperature modes of
soft ice cream production. The developed polycomponent
dry mix provides production of enriched soft ice cream
