CHEMICAL COMPOSITION AND ORGANOLEPTIC CHARACTERISTICS OF PROCESSING BAT (Pteropus alecto) FRESH MEAT. Study was done to evaluate chemical composition and preference degree of the consumers on the processing bat meat compared with beef, chicken and cakalang fish using steam cooking method, flavor cooking and spicy cooking method. Chemical composition was analyzed by proximate analysis using procedures of the Association of Official Analytical Chemists. The organoleptic test was done by hedonic test. Data of the hedonic test were analyzed using Kruskal-Wallis method. To evaluate data distribution of the panelist respons on the sample test, the data were using plot graphic box. The hedonic scales were using 1 to 7. The variables used were including color, taste, flavor, tenderness and general acceptance. Results of proximate analyses of bat meat based on fresh meat indicated that water content was 67.21 percents and protein was 20.48 percents. Based on dry matter, the protein contents of bat meat, pork, chicken, and cakalang fish were 48.97 percents, 69.08 percents, 67.14 percents, and 69.41 percents, respectively. The water contents were 5.76 percents, 9.92 percents, 8.27 percents, and 9.90 percents, repsectively; the calcium (Ca) contents were also 10.62 percents, 1.09 percents, 1.36 percents, 1.38 percents, respectively; while Phosphor (P) contents were 1.46 percents, 0.69 percents, 0.66 percents, and 0.72 percents, respectively. Variance analysis for organoleptic test showed that meat type with different processing affected significantly on taste, color, flavor, tenderness and general preference of bat meat, beef meat, chicken meat and cakalang fish by steam cooking, chicken flavor, and spicy cooking methods. Conclusion, bat meat contained protein relatively lower than that in pork meat, chicken meat, and cakalang fish, but mineral contents were relative higher. Results of organoleptic test showed that preference degree of processing meat were higher on using spicy flavor. The specific test on taste, color, flavor, tenderness and general responsed showed relatively the same responses by the panelists.   Key word: Chemical composition, organoleptic test, processing bat meat

The authors study three fractions obtained as a result of hydrolysis of smoked sprat heads (under temperature of 130oC and presser of 0.25 MPa) – fat, protein water-soluble, and protein-and-mineral ones. Waste from sprat production of two fish canning complexes of the Kaliningrad Region - “RosCon” and “Kolkhoz for the Motherland” - was used as raw material. Hydrolysis was carried out in an aqueous medium in two ways - with preliminary separation of fat and without this operation. The protein fraction was sublimated and its quantitative and qualitative indices were examined - mass yield, solubility, chemical composition and molecular fractional composition of the obtained peptide fractions were determined. The output of sublimated protein fractions is practically independent of the type of raw material and the method of pre-treatment and is 6.47.9% of the mass of raw materials. The chemical composition of protein fractions varies widely in terms of fat (1.4–8.3%), minerals (9.8–13.4%) and proteins (72.1–80.2%). The solubility of the peptide fractions ranged from 91-98%. The molecular weight assessment results showed a high content of a low molecular weight fraction of peptides with an MM of less than 10 kDa in all experimental samples (about 38%). This indicates a high digestibility and biological value of the obtained peptide compositions. Sublimated peptide compositions had typical organoleptic characteristics, pleasant aroma and taste of smoked fish. Ключевые

Aflatoxin M1 (AFM1) is a well-known mycotoxin that can be found in the milk of animals that have ingested feed contaminated with aflatoxin B1 (AFB1). In Italy, the development of donkey farms is mainly due to growing request of donkey milk, which is considered an incomparable substitute for human mother’s milk for its chemical composition and organoleptic characteristics. The aim of this study was to assess the occurrence of AFM1 in donkey milk produced in a farm in Northern Italy, also in view of the few data available about the presence of this mycotoxin in this type of milk. Therefore, 63 milk samples were collected and analyzed using a fast and sensitive HPLC and fluorescence detection (FLD) method previously optimized and validated. None of the milk samples collected were found to be contaminated at a level above the limit of quantification (LOQ) (0.0125 ng/mL), while only one sample showed traces of the mycotoxin at a concentration between the limit of detection (LOD) and LOQ (0.0044 ng/mL), well below the legal limit established for infant milk and follow-on milk (0.025 ng/mL). These results are in line with those of the few similar surveys carried out on donkey milk and seem to indicate a low risk of AFM1 contamination for this food.

The nutritional value and organoleptic evaluation of rabbit showed that the meat of rabbits raised on the eco-farm and in the modular rabbit house did not differ from each other and had the best nutritional and biochemical qualities, indicating the prospects of using modular farms to produce high quality products. A high percentage of fresh meat yield was found – 53.6 and 53.9% in rabbits raised in the module and on the eco-farm. Rabbit carcasses from the module had more fat by 1.1% and slightly enlarged kidneys due to the peculiarity of the equipment. Changes in the chemical composition – a slight increase in moisture and fat content (by 0.2%) in the meat, which was obtained by raising in the modular rabbit house compared to the meat of rabbits raised on the eco-farm – were founded. At the same time there was 0.3% less protein and 0.1% less sol. In general, the difference in chemical composition was insignificant, which indicated the identity of the analyzed samples. The organoleptic characteristics of rabbit meat in the carcass at slaughter and after heat treatment were studied. Muscle consistency was dense, elastic, when pressed the formed hole was quickly leveled; fat was dense. The aroma was specific for fresh meat. All samples taken from sampling of “Hy-plus” hybrid rabbits raised in the modular rabbit house and those raised on the eco-farm had the highest scores. The studied samples by organoleptic evaluation did not differ from each other and corresponded to high quality rabbit. Carcasses of hybrids in the experimental groups had a high content of saturated, monounsaturated and polyunsaturated fatty acids and the lowest content of cholesterol (0.04 g/100 g). The difference between the amino acid composition of meat and the lipid composition of fat in the study groups was insignificant

Проведено конструирование рецептуры соусов на основе творожной сыворотки к мясным и рыбным блюдам. Разработана рецептура пикантных соусов с использованием творожной сыворотки, овощного сырья и СО2-экстрактов пряностей. Сбалансированность рецептурного состава новых пищевых продуктов достигнута симплекс-методом. Оптимизационная задача решена по органолептическим показателям, химическому составу и энергетической ценности продукта. Для моделирования рецептур использовали трехфакторные симплекс-центроидные планы. Согласно матрице планирования приготовлены образцы смесей, содержащие в качестве постоянной части творожную сыворотку (43%); оставшуюся вариативную часть составили, %: пшеничные хлопья 13,0; томатная паста 34,4; растительное масло 2,3; соль 3,0; сахар 3,0; уксус столовый 1,0; хитозан 0,2; СО2-экстракты 0,004. Образцы с различным соотношением компонентов получили высокую органолептическую оценку по 5-балльной дегустационной шкале. Пищевая ценность разработанного соуса 116,6 ккал – выше классического томатного (95 ккал), ниже майонеза (510 ккал/100 г), что позволяет рекомендовать новый продукт для диетического питания. The formulation of sauces based on curd whey for meat and fish dishes was designed. The formulation of spicy sauces using curd whey, vegetable raw materials and СО2-extracts of spices was developed. The balance of the formulation composition of new foods is achieved by simplex method. The optimization problem is solved on organoleptic characteristics, chemical composition and energy value of the product. Three-factor simplex-centroid plans were used to model formulations. According to the planning matrix prepared samples of mixtures containing as a permanent part of the whey (43%); the remaining variable part was, %: wheat flakes 13,0; tomato paste 34,4; vegetable oil 2,3; salt 3,0; sugar 3,0; vinegar table 1,0; chitosan 0,2; СО2-extracts 0,004. Samples with different ratios of components received high organoleptic evaluation by five-points tasting scale of assessments. The nutritional value of the developed sauce 116,6 kcal – above the classic tomato sauce (95 kcal), below mayonnaise (510 kcal/100 g), which allows us to recommend a new product for dietary nutrition.
