Physical, nutritional and sensory quality characteristics of semi sweet type biscuit made by mixing wheat flour and pumpkin puree were studied. Wheat flour and pumpkin puree were mixed in the ratio of 100:0, 90:10, 80:20, 70:30 and 60:40. Diameter and thickness of biscuit decreased and bulk density increased as the amount of pumpkin increased. The nutritional quality of biscuit was positively influenced by the incorporation of pumpkin. Pumpkin increased protein, crude fibre, calcium, carotene and vitamin C of biscuit. The sensory quality of biscuit made from the mixed flour containing 70 parts of wheat flour and 30 parts of pumpkin puree was best. The biscuit made fromthe flour of this composition contained 2.53% moisture, 9.7% protein, 12% fat, 0.51% crude fiber, 0.81% total ash, 76.98% carbohydrate, 13.01 mg/100g carotene, 1.04 mg/100g Vitamin C, 1.88 mg/100g iron, 35.6 mg/100g calcium and energy value of 454.72 Kcal/100g dry matter.

The evaluation of nutritional quality of Chinese cabbage and the effects of cultivar, weed incidence, plant density and growing season were observed in integrated cultivation system. Mean contents of analysed compounds were as follows: 6% of dry matter, 10% of crude fibre, (in mg/kg of f.m.): 2,199 mg K, 289 mg Ca, 146 mg Mg, 111 mg Na, and 316 mg of vitamin C. Mean content of nitrates reached the value of 647 mg/kg. A significant effect of cultivar on the content of all observed substances in cabbage heads excluding magnesium was thus confirmed; however, a decrease of nitrates was found in the treatment with higher plant density. Weed cultivation caused slightly (insignificantly) higher nitrates content in cabbage heads by 100 mg/kg. Growing season showed a significant effect on content of some evaluated compounds. Integrated cultivation of Chinese cabbage could be an adequate approach to ensure nutritionally valuable products with low nitrates content.

Purpose Due to the rise in urbanization, demand for easily prepared foods such as pastries and noodles has risen. But the high price of wheat in the global market puts financial stress on low-income people, especially on those living in tropical regions, where wheat does not thrive well. They depend solely on imported wheat, which is expensive due to importation cost, or seek other relatively less-nutritious cereals. Therefore the purpose of this paper is to investigate the possibility of supplementing wheat flour with flour from relatively cheap and easy-to-produce root tuber, such as cassava, potato and sweet potato. Design/methodology/approach Strong-, medium- and weak-gluten wheat flours were supplemented with flour from cassava, potato and sweet potato at 10, 20 and 30 percent. Strong gluten composites were used to make bread, whereas medium and weak gluten composites were used for cookie and noodle production, respectively. Protein, ash, fat, crude fiber, moisture, carbohydrate, gluten, zeleny and energy contents of each composite were tested. Findings The nutritional and sensory quality of bread, cookies and noodles made from wheat flour supplemented with root tuber flour at 10, 20 and 30 percent was assessed. Results revealed that mixing wheat flour and root tuber flour has important effects on the moisture, protein, carbohydrate, fat, ash, gluten, zeleny sedimentation value and crude fiber content of the resulting mixture. Moisture and carbohydrate increased while protein and fat significantly (p<0.05) decreased with increasing root tuber flour levels in formulations. Gluten content also decreased significantly with rising root tuber flour concentrations. There was a mild reduction in bread’s general acceptability at 10 and 20 percent in potato composites; thus potato flour was still acceptable at 20 percent. Cassava flour composite also topped with a general acceptability score of 69.26 at 20 percent in cookies, whereas sweet potato composite achieved a score of 84.81 in noodles. Originality/value This work has successfully confirmed that wheat flour could be supplemented up to 20 percent with root tuber flour without compromising the nutritional and sensory quality of products. It has also demonstrated that different products require different root tuber flour substitution for optimum results. Potato at 10 percent substitution was found to be best for bread production. Cassava and sweet potato at 10 percent substitution were also best for cookies and noodles, respectively. With respect to protein content only, sweet potato substitution is better than cassava and potato.

Oil palm press fibre is a byproduct of agro-industry that has a low nutrient content. To improve the nutritional quality of oil palm press fibre, it is carried out with biological processing techniques utilizing the work of indigenous microorganisms derived from local microorganisms of it. The research was conducted experimentally using a completely  randomized design (CRD) factorial pattern with 2 factors (3 x 3), namely first factor such as dose of local microorganisms (D 1 = 1%, D 2 = 3% andD 3 = 5%) and second factor such as long of fermentation (L1 = 7 days, L2 = 14 days and L3 = 21 days), with 3 replications. The parameters of this study consisted of the nutritional content of oil palm press fibre fermented such as moisture, dry matter, crude protein, crude fat, crude fiber, ash, and BETN. Based on the results of the study, it was found that the combination of treatment with a dose of local microorganisms 5% and fermentation time of 14 days had a significant effect (P<0.05) in increasing crude protein content and did not have a vegetable effect (P>0.05) in increasing the dry matter content and BETN and reducing water content. , crude fat, crude fiber and ash. Giving various doses of local microorganisms and fermentation time can increase crude protein content and have not been able to increase dry matter and BETN content and reduce moisture content, crude fiber and ash.

Sugar beet pulp (SBP) is a by-product of the sugar industry in which the dietary fiber content ranges from 73% to 80%. Compared to cereal fibers mainly used in biscuit production, sugar beet fibers are gluten free and have a perfect ratio of 2/3 insoluble fiber. In this work, sugar beet pulp was extruded with corn grits (ratios of corn grits to sugar beet pulp in extrudates were 85:15, 70:30, and 55:45), and the obtained sugar beet pulp extrudates (SBPEs) were used for improving the nutritional quality of cookies. The wheat flour in cookies was replaced with SBPEs in the amount of 5, 10, and 15%. The influence of three factors (the percentage of sugar beet pulp in the SBPEs, the size of the SBPE particles, and the percentage of wheat flour substituted with SBPEs) and their interactions on the nutritional quality of cookies, as well as their physical and sensory characteristics are examined using the Box–Behnken experimental design. The addition of extruded sugar beet pulp (SBPEs) significantly increased the amount of total dietary fiber and mineral matter of cookies. On the whole, the addition of SBPEs increased cookie hardness, but the hardness decreased with an increase in extrudate particle size. Sensory characteristics (except for the taste) were the most influenced by extrudate particle size.

Изучено влияние технологических приемов на качество муки. Определяли качество зерна озимой мягкой пшеницы Краснодарская 57 по ГОСТ 93532016. При определенной технологической схеме 78м двухсортном выходе муки было получено 70 муки 1го сорта и 8 муки 2го сорта. Качество муки соответствует ГОСТ Р 521892003. Мука 1го и 2го сортов обладает пресным вкусом, запахом, свойственным пшеничной муке массовая доля влаги 14,7 (1й сорт) и 13,5 (2й сорт). Наличие минеральной примеси, зараженность вредителями не установлены. Содержание металломагнитной примеси 0,041 мг (1й сорт) и 0,048 мг (2й сорт), что соответствует стандарту. Массовая доля золы в пересчете на сухое вещество составила не более 0,69 для муки 1го сорта и 0,70 для муки 2го сорта, белизна у. е. прибора РЗБПЛ 52,4 (1й сорт) и 30,0 (2й сорт). Качество сырой клейковины для муки 1го и 2го сортов составляет 70,0 и 78,0 у. е. прибора ИДК1 (I группа) соответственно. Определены также крупность помола остаток на сите 2,0 1,9 и 2,2, число падения 200 и 182 с, массовая доля сырой клейковины 30,3 и 26,6, содержание протеина 13,2 и 12,5 для муки 1го и 2го сорта соответственно. Цвет белый для муки 1го сорта и белый с желтоватым оттенком для муки 2го сорта. По органолептическим и физикохимическим показателям пшеничные отруби соответствовали ГОСТ 716966. В результате гидротермической обработки зерна с применением холодного кондиционирования и отволаживанием в течение 4 ч выход сырой клейковины вследствие повышения водопоглотительной способности белков увеличился с 25 до 26,6. Одновременно наблюдалось ослабление клейковины, возрастание ее растяжимости. При отволаживании зерна в течение 6 и 8 ч происходило некоторое увеличение выхода сырой клейковины, : 27,9 и 30,3 соответственно. Качество клейковины составило 70 у. е. прибора ИДК1, что соответствует I группе качества. Выход муки при 4часовом отволаживании составил 64, при 6часовом увеличился до 66. Высокий показатель общего выхода муки 78 был установлен при 8часовом отволаживании. Холодное кондиционирование способствовало улучшению мукомольных и хлебопекарных свойств зерна, увеличению выхода сортовой муки при меньших затратах электроэнергии. The influence of technological methods on the quality of flour has been studied. The quality of winter wheat Krasnodarskaya 57 was determined according to GOST 93532016. At a certain technological scheme with a seventyeight percent twograde flour yield was obtained 70 flour 1st grade and 8 flour 2nd grade. The quality of flour corresponds to GOST R 521892003. Flour of the first and second grades has a fresh taste, the smell characteristic of wheat flour, the mass fraction of moisture 14,7 (1st grade) and 13,5 (2nd grade). The presence of mineral impurities, pest contamination has not been established. The content of metallomagnetic impurities was found to be 0,041 mg (1st grade) and 0,048 mg (2nd grade), which corresponds to the standard. Mass fraction of ash in terms of dry matter was no more than 0,69 for first grade flour and 0,70 for flour of the second grade, whiteness conditional units of the device RZBPL 52,4 (1st grade) and 30,0 (2nd grade). The quality of wet gluten for flour of 1st and 2nd grades is 70,0 and 78,0 units of the device IDK1 (I group) respectively. Were also defined the particle size of grinding the residue on the sieve 2,0 1,9 and 2,2, the falling number 200 and 182 seconds, the mass fraction of wet gluten 30,3 and 26,6, protein content 13,2 and 12,5 for flour 1st and 2nd grade, respectively. The color is white for the flour 1st grade and the white with a yellowish tinge for the flour of the 2nd grade. By organoleptic and physicochemical indicators, wheat bran complied with GOST 716966. As a result of hydrothermal grain treatment with the use of cold conditioning and softening for 4 hours, the yield of raw gluten due to an increase in the waterabsorbing ability of proteins increased from 25 to 26,6. At the same time, a weakening of the gluten was observed, an increase in its extensibility. When softening grain for 6 and 8 hours there is some increase in the yield of wet gluten, : of 27,9 and 30,3 respectively. The quality of gluten was 70 units of the device IDK1, which corresponds to the quality group I. The yield of flour with fourhour softening was 64, with sixhour increased to 66. High total yield of flour of 78 was set when the eighthour softening. Cold conditioning contributed to the improvement of the milling and baking properties of grain, increasing the yield of highgrade flour with less power consumption.

This work consists of studying the influence of the desamerization of the mesocarpe on the chemical composition and the sensorial quality of the jam, based on the bitter orange. The results of the various analysis show that desamerization decreases acidity, sugars, protein, and bioactive compound levels (carotenoids, polyphenols, and vitamin C), but desamerized jams still remain an important source of antioxidant compounds with antioxidant potential in the diet. Concerning the sensory analysis of the jams, the results show that the jam desamerized with water presents the same bitterness as the bitter jam and that the salt significantly reduces the bitterness of the jams.

Aloe Vera leaves have great potential as an economic supplement with an adequate nutritional profile. The current study aimed to fortify plain (loaf) cakes with Aloe Vera leaf gel (AVG) powder. AVG was freeze-dried to produce Aloe Vera powder (ALP), and four plain (loaf) cakes were prepared with different proportions of ALP (0, 4, 6, and 8%). ALP contained significantly (p < 0.05) more protein (22.23 vs. 12.24), ash (19.83 vs. 0.64), and iron (175 vs. 3.05) than refined wheat flour (RWF). Along with total polyphenols and total flavonoids, ALP demonstrated good antioxidant activity. ALP-cakes and RWF-cakes were also evaluated for their nutritional and functional properties. The addition of 6 and 8% ALP to the formulation increased total polyphenols, total flavonoids, and antioxidant activity in plain (loaf) cakes. Hardness and chewiness increased in ALP-cakes but decreased in RWF-cakes, while cohesiveness and springiness decreased in ALP-cakes. In conclusion, the best formulation was a 4% ALP incorporated cake, and ALP can be supplemented in plain cakes at a rate of up to 8% to improve nutrient value. This is the first study to evaluate the quality characteristics of fortified plain (loaf) cakes using ALP.

The study was to conduct to evaluate the chemical composition and nutritive values of feedstuffs (forages and concentrate mixtures) used for dairy goats nutrition in Vojvodina. Samples were collected from six farms, including one organic farm. The results showed that the relative feed values of analyzed forages were in the range of good, medium to lower quality. Average protein content from lowest to highest for investigated forages was: corn silage (Zea Mays) (65.37-82.57g kg??DM), alfalfa haylage (Medicago sativa L.) (159.99-184.17g kg??DM), pasture (185.30g kg?? DM), and alfalfa hay (Medicago sativa L.) (167.48-203.60g kg??DM). The non-fibre carbohydrates and protein content most varied in organic hay samples (cv: 29.25% and 19.09%, respectively). Generally, feedstuffs used in organic nutrition, including organic concentrate, were of lower nutritional quality and moreover contained higher amounts of crude fibre and lignin. Especially, a high source of variation was observed in investigated concentrate mixtures for the crude protein content (p<0.0001), ranged from 135.32 to 209.87g kg??DM. Corn silages also varied substantially in their chemical composition and significant difference (p<0.05) was observed in regard to acid detergent fibre (ADF) and lignin content (ranged: ADF: 242.20-319.24g kg??DM; ADL: 27.98-52.54g kg??DM, respectively). Furthermore, pasture contained the most soluble materials during May and June and their content was related inversely to crude fibre amount. This survey highlights that investigated farms still pay insufficient attention to the quality of the feedstuff. For the development of intensive goat farming, greater emphasis should be placed on using higher quality feedstuffs, as well, standards for feed quality must be considered and established.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.
