Biological Value

Milk chocolate is particularly popular with different age groups. It is characterized by low protein content with a large amount of fats and carbohydrates determining the food imbalance of the product. In conditions of high-grade animal proteins deficiency the selection of high-quality protein-containing ingredients for food production is very relevant. The aim of this work is to study the protein adequacy of various components of milk chocolate to enhance its biological value. The amino acid scale method has been used to assess the biological value of proteins; it is based on the determination of amino acid (chemical) score. It has been found that the limiting biological value amino acid for classical white raw ingredients of milk chocolate (cocoa products and milk powder) is methionine + cysteine. For constructing chocolate formulas with increased biological value it is advisable to use protein-containing raw materials (whey protein concentrate, oat flour, etc.) to compensate for the limiting amino acids. The indicator of amino acids utilitarianity of proteins of raw milk chocolate components has been calculated. On the basis of the utilitarian index we have established the coefficient of utilitarian of the amino acid composition of the raw materials characterizing essential amino acids' balance. We have determined the biological value of protein and the amino acid composition imbalance coefficient. It has been found that the amino acid composition of milk and whey protein concentrates is most balanced compared to the amino acid composition of traditional protein-containing raw components of milk chocolate. The limiting acid of whey protein concentrate is valine, which makes its use in the manufacture of chocolate products more attractive compared to milk protein concentrate (the limiting amino acid is methionine + cysteine). In the group of vegetable non-conventional raw materials oat and buckwheat flour are characterized by the best indicators of biological value. The amino acid adequacy of oat flour is comparable to the qualitative protein indicators of cocoa products, the limiting amino acid is lysine. Buckwheat flour is characterized by the smallest imbalance in amino acid composition, which distinguishes the proteins of this raw material with the highest degree of digestibility compared with the proteins of all the studied protein-containing components of milk chocolate.

The Past

The addition of essential amino acids to all-vegetable diets, so as to raise the biological value of their proteins to the level of animal-protein concentrates, has often been advocated in the past by animal nutritionists. This aim was frustrated in practice since it was impossible, until recently, to secure the necessary supplies at prices that would make such additions economical. Feeding stuffs with added amino acids are now being sold commercially. This is possible following the manufacture of synthetic DL-methionine and crude L-lysine monochloride.It seemed desirable, therefore, to carry out investigations into the potential value of these amino acids to the pig feeder. This paper deals with the effect on growth, food utilization and retention of nitrogen of adding small amounts of lysine and methionine to the diet. An attempt is made to correlate the amino acid composition of the pig's diet with its rate of growth, the energy supply being adequate.

Two proteins, previously described by the authors as BI (S020, buffer 12 S) and AIVS (S020, w 1.7 S) have been isolated from eight varieties of rapeseed belonging to Brassica campestris L. and Brassica napus L. species. These proteins have similar chromatographic and electrophoretic characteristics but differ in amino acid composition, particularly with regard to the sulfur-containing amino acids. One of the rapeseed samples was obtained from plants grown on sulfur-deficient soil. The sulfur deficiency produced, in the mature seed, a much reduced protein content and appeared to affect the structure of the protein BI.

Abstract Inter- and intralaboratory variation in amino acid composition of casein, soy flour, and fish flour was examined for 5 cooperating laboratories, utilizing ion exchange chromatographic analyses for amino acids. Duplicate analyses within laboratories exhibited coefficients of variation of 3.7 to 4.4%. Hydrolysis was observed to affect amino acid recoveries to a significant degree, with some amino acids affected to greater extents than others. Laboratories utilizing Moore-Stein type analytical procedures did not appear to be more precise than those using the Piez-Morris method. Adjustment of data to constant total recovery values reduced interlaboratory variation considerably and suggested that recovery constants may be of value in comparing data from different laboratories. Results indicated that different laboratories employing varying analytical procedures may produce practically identical results from a standard sample, although variation may be observed due to characteristics of a specific system. Most variation in results was likely due to sample manipulations rather than to analysis per se.

The Ideal

The article presents a comparative characteristic of the amino acid composition of the «ideal» protein and the developed formulation of combined products. The results of calculation of the amino acid score (AAS) of the essential amino acids in the novel protein product are given. AAS is within the range from 105 to 143%. The developed formulation of a combined product has an insignificantly limited amount of valine (98%). Based on AAS, the difference coefficients of the examined amino acids were calculated (from –0.2 to 4.36%) and the biological value of each of the components of the formulation was determined. The nonessential amino acid composition of the «ideal» protein, raw materials of vegetable and animal origin and products produced according to the developed formulation are considered. The formulation of the novel combined product has been characterised as a full and balanced amino acid composition, suitable for nutrition, containing all the amino acids necessary for protein synthesis. The maximum AAS has been noted in steamed meatballs with beef, mutton and cabbage, which by 7.61% exceeds the AAS of steamed meatballs with beef and mutton and by 9.38% – the AAS of steamed meatballs with beef. The examined product has a high biological value – from 95 to 99%. The developed mathematical model is applicable to specification of the formulation under more specific conditions, for instance, for a particular age category. The novelty of the model consists in its priority with respect to the organoleptic properties and consumer preferences of the developed formulation.

Food proteins, besides being used as sources of energy and providing the body with amino acids for the protein synthesis, are important biological objects that help maintain the overall health of a person, participate in the growth and development of the organism, and the functioning of cellular metabolism. Due to the ability of maintaining a balance between anabolic and catabolic metabolism, industrial proteins have achieved the status of a biologically active ingredient or substance that promotes health, which is associated with the placement of peptides or amino acids in the chain encoded in each protein. The article presents the data of conducted researches on the influence of created functional composition containing protein (FCP) of the given composition and properties on SCORE and indicators of  biological efficiency  of cooked sausages proteins. Biological value, as a criterion for evaluating the protein, is very important for determining the effectiveness of its use by the organism. The product's amino acid composition is one of the indicators of its biological value. As a result of the obtained data analysis on the study of the experimental cooked sausage's amino acid composition, it was found that the experimental samples using the FCP were balanced by the content of essential amino acids in comparison with the control sample. For a experimental sample number 1 using FCP in combination with red poultry compared to the control sample, the number of all essential amino acids is increased by an average of 67.2%. For the experimental sample number 2 using FCP combined with mechanical deboned poultry meat (MDPM), there is a decrease in the number of amino acids such as lysine, valine, sulfur-containing (compared to the experimental sample number 1), the SCORE for which is less than 100%. Calculating the indicator of biological value and comparative redundancy, and the coefficients of differentiation the amino acid composition (CDAAC) and utility, generalized the effect of FCP on the biological efficiency of the product's protein. The use of FCP in the cooked sausages technology in the amount of 30% increases the biological value of experimental samples by an average of 3%, utilitarian utilization rate – by 8.4%, and reduces the comparative redundancy by an average of 50%, CDAAC – by 4% compared to the control sample. Replacement of the meat raw material developed by the FCP in the recipes of cooked sausages increases and balances the amino acid composition of the experimental samples.

Researching of the amino acids contents in medicinal plant raw materials is an important task of pharmaceutical science and practice, because complexes of amino acids used for the corrections of hepatobiliary disorders, nervous and cardiovascular systems. The aim of this study was to conduct a qualitative and quantitative analysis of amіno acids composition of these representatives. The article presents the results of the amino acid composition investigation of the above-ground parts of 10 species belonging to Lamiaceae Juss. Family (Ocimum, Hyssopus, Dracocephalum, Lophanthus, Monarda and Satureja genera). By paper chromatography it was identified several amino acids. HPLC analyzes revealed the content and composition of more than 20 amino acids. The highest total amino acid composition was found in the herb of the genus Ocimum. It was identified 10 essential and non-essential 9 amino acids in each herb, and 3 nonproteinogenic amino acids also. It was established that in all plant materials dominate quantitatively nonessential amino acids (asparagine, proline, glutamic and aspartic acid). Among the essential amino acids arginine and threonine predominate.

Introduction. Grain germination can improve the nutritional value and functional properties of grain. The research featured the effect of technological processing on the quality of the finished product as in the case of natural, germinated, and canned wheat grains. A set of experiments was conducted to define the mineral substances and amino acid composition as factors that affect the chemical composition of a product during its production. Study objects and methods. The research featured soft wheat grain, germinated wheat grain, and canned germinated wheat grain. The latter consisted of 55% of pre-treated germinated wheat grain and 45% of filling, which contained 4.5% of sugar and 3.5% of salt. The content of mineral substances was determined by atomic-emission spectrometry with inductively coupled plasma using an atomicemission spectrometer Optima 2100 DV (USA). The amino acid composition was determined using a liquid chromatograph Agilent 1200 (USA). Results and discussion. 100 grams of canned germinated grain contained about 15% of daily manganese, 12% of chromium (III), 8.4% of copper, and 8.3% of zinc. Canned germinated wheat demonstrated a high biological protein value and contained 20.6% of essential amino acids. As for amino acids, canned germinated wheat grains had a high content of proline (958.4 mg/100 g) and glutamic acid (2456.4 mg/100 g). The characteristics of the nutritional value of canned protein from germinated wheat grains included amino acid rate, amino acid feedstock difference coefficient (AAFDC), and potential biological value (PBV). The proteins of canned germinated wheat appeared inferior in their amino acid composition and contained insufficient amounts of lysine and threonine. The coefficient of differences in amino acid scores was 71.9%, while the potential biological value of the protein was 28.1%. Conclusion. Germinated grains have a certain set of minerals and amino acids in their composition. Therefore, they can be used to develop canned foods or dishes for public catering industry. The effect of technological processing on the mineral composition of the finished product resulted in the loss of mineral substances from 45 to 85%. Moreover, germinated wheat should be combined with products that are rich in lysine and threonine.

Dried stevia leaves (Stevia rebaudiana Bertoni) were used as objects of research. We studied the leaves of stevia varieties Ramon sweetener grown in the Penza region, the leaves of stevia varieties Ramon sweetener grown in the Tver region, Krasnodar region, the Republic of Crimea, as well as imported raw stevia from India and Paraguay. The purpose of this work is a comparative study of the amino acid composition of raw stevia grown in different conditions. The amino acid composition of stevia leaves (Stevia rebaudiana Bertoni) was revealed by capillary electrophoresis.13 amino acids were identified, of which eight are "essential" (lysine, phenylalanine, histidine, leucine, isoleucine, methionine, valine, threonine). The proportion of essential amino acids in stevia raw materials ranged from 2.99 to 4.64%. The content of interchangeable acids was: tyrosine from 0.24% to 0.36%, Proline from 0.44 to 0.68%, serine from 0.77 to 1.03%, alanine from 0.48 to 0.83%, glycine from 0.40 to 0.68%. The total amount of amino acids detected is higher in the Ramon sweetener variety grown in the Penza region (9.52%) compared to other samples, the lowest amount is found in stevia grown in Paraguay (6.46%). The results obtained indicate the prospects for further studies of the amino acid composition of Stevia rebaudiana and can characterize this species as a source of valuable medicinal substances with a wide range of pharmacological activity.

We have presented a method for the extraction and isolation of the gonococcal H.8 antigen. There was no evidence of contamination by other gonococcal proteins, phospholipids, or LPS. The purified H.8 antigen was subjected to preliminary analysis and appeared to be a proteolipid consisting of both protein and lipid components. The amino acid composition was unusual; the peptide portion of the antigen was an alanine and proline-rich molecule that lacked aromatic and sulfur-containing amino acids. The overall amino acid composition is hydrophobic. A lipid constituent was also identified; it was made up of at least two lipid components, which were unique to the H.8 molecule. The chemical nature of the association of the protein and lipid is presently unknown, but it is clearly a tenacious one.
