The aim of the study was to determine technological and consumption quality of some offal components obtained from Pulawska and Polish Landrace fattening pigs, and to analyse the eating quality of the offal products. The study material consisted of 100 fattening pigs: Pulawska (PUL) and 50 Polish Landrace (PL) pigs. The offal components were analysed for physical traits, chemical composition and energy value. Offal products were made from the offal and their physical, chemical and organoleptic parameters were evaluated. Our study showed that breed had a significant effect (p ≤ 0.05) on pH45 of the tongue, heart (PUL > PL), lungs and kidneys (PUL < PL), and on the fat content of the tongue, heart (PUL > PL), liver and kidneys (PUL < PL). A highly significant effect of breed (p ≤ 0.01) was observed for protein content of the lungs, liver (PUL < PL) and kidneys (PUL > PL), for collagen content of the kidneys (PUL < PL) and liver (PUL < PL), and for energy value (p ≤ 0.01) of the heart (PUL > PL) and liver (PUL < PL). Moreover, our results indicate that the organoleptic quality of the evaluated offal products was higher for Pulawska than Polish Landrace pigs, in particular with regard to consistency (p < 0.05) and flavour (p < 0.01) of the liver sausage.

AbstractThree hundred and eight cattle, comprising steers and heifers from continental and British crosses were finished on an 18-month beef production system at Warren Farm, Lambourn, Berkshire and slaughtered across a range of fatness levels. The eating quality of roasting joints (semimembranosus.) and sirloin steaks (longissimus thoracis et lumborumj was evaluated and the chemical composition of the lean tissue was taken on a subset of the samples. Results suggested that the greatest differences between the breeds was in the joints. There were significant (P < 0·01) differences in the lipid, moisture and collagen contents of the lean tissue of the joints from the different sire breeds. The Belgian Blue sire progeny had significantly lower lipid content than the Charolais or Aberdeen Angus crosses, and significantly lower collagen content than the Aberdeen Angus cross. In addition joints from Belgian Blue crosses were more tender than joints from other breed crosses. Although the lipid and moisture contents of the steaks from different sire crosses were significantly different there was no evidence of differences in eating quality. Perhaps surprisingly there were no significant relationships between the eating quality and chemical composition between or within breed. Irrespective of breed, carcass fatness influenced the juiciness of both the joints and the steaks although the response was different for continental crosses and British crosses and depended on carcass sex. Over and above this response, steer meat was generally more juicy than heifer meat.

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.

1. Three contrasting varieties of spring oats were grown at six centres in England and Wales for three seasons, at two levels of manuring. They were harvested at two stages of ripeness, and both straw and grain were analysed for all treatments.2. Varietal differences in composition between samples of straw grown under similar conditions and harvested at comparable stages of ripeness were negligible. In this respect there was no relationship between quality of straw and that of grain.3. Differences in composition attributable to environment were very large. Crude protein content ranged from 1·9 to 7·6%, and crops grown under cool and wet conditions always yielded a better quality straw than those grown under the warmer and drier conditions in the south of England.4. The chemical composition of oat straw changed very little between the early ‘binder-ripe’ stage and the fully ripe ‘combine’ stage, although physically it tended to become more brittle and less attractive in appearance. The grain also showed little change in composition between the two times of harvesting.5. A spring dressing of 2 cwt. per acre of nitrochalk increased the protein content of the straw very considerably, but the response varied widely with conditions. The average increase at all centres over three years was 20%.6. Under cool and moist conditions the composition of oat straw was comparable with that of meadow hay.

Background. Flour confectionery in Ukraine is in high demand, it’s made gluten-free mainly using corn and rice flour, rarely buckwheat. In our opinion, an inte­resting alternative to these types of flour will be to use sesame flour in the recipe and technology of gingerbread products, due to its convenience and unique taste. We have not found any research on the use of sesame flour in the technologies of gingerbread flour confectionery in available sources. The aim of this research is to scientifically substantiate and develop the techno­logy of gluten-free gingerbread with a complete replacement of wheat with sesame flour. Materials and methods. The object of research is the technology of gingerbread using gluten-free finely ground sesame flour. As a control sample, high-grade wheat flour was used for the preparation of children’s gingerbread by custard. The quality of gingerbread is determined according to DSTU 4187:2003 (State Stan­dards of Ukraine). Organoleptic evaluation of the samples was performed on a 5-point scale. The calculation of nutritional value (proteins, lipids, carbohydrates, dietary fiber), and the content of minerals is carried out according to the tables of chemical composition. Results. With the help of test doughs, it was found that in the recipe of children’s gingerbread it is possible to completely replace wheat flour with sesame and "dry perfume" (a mixture of spices) with nutmeg. According to organoleptic parameters of two types of gingerbread from wheat and sesame flour, the latter were less porous, but had a pleasant rich taste of sesame and nutmeg aroma. As a result, the identified shortcomings do not have a significant impact on the overall quality of gluten-free products. The technological scheme of preparation of "Sesame" gingerbreads with the use of sesame flour and nutmeg has been developed. The chemical composition, mineral content and energy value of control and deve­loped gingerbreads were calculated. The latter had better nutritional and biological value. Conclusion. The technology of gingerbread dough and gingerbreads with the use of sesame flour and nutmeg has been developed, which improves the organoleptic and physicochemical parameters of the new "Sesame" gingerbreads, makes their taste more expressive and enriches them with useful microelements. By replacing wheat flour with sesame, the finished products do not contain gluten and can be recommended to certain categories of consumers who suffer from diseases associated with wheat protein intolerance and allergy to it.

Kualitas tempe ditentukan oleh mikroorganisme yang berperan selama proses fermentasi berlangsung. Mikroorganisme utama dalam fermentasi tempe adalah Rhizopus spp. yang sekarang umumnya berasal dari salah satu jenis laru komersial. Akibatnya, keragaman Rhizopus spp. yang digunakan pada fermentasi tempe mengalami penurunan. Oleh karena itu, penelitian ini bertujuan untuk mendapatkan informasi tentang peran beberapa galur R. microsporus yang berasal dari “laru tradisional” dalam menentukan kualitas tempe. Tempe diproduksi menggunakan R. microsporus TB 23 (Tempe TB 23), R. microsporus TB 32 (Tempe TB 32), R. microsporus TB 51 (Tempe TB 51), R. microsporus TB 55 (Tempe TB 55) dan tempe menggunakan laru komersial (Tempe K). Kualitas tempe ditentukan melalui pengukuran tekstur, warna, cita rasa, aktivitas antioksidan, dan komposisi kimia (kadar air, kadar lemak, kadar protein, dan kadar serat kasar). Hasil penelitian menunjukkan bahwa tekstur, warna, dan cita rasa dari Tempe TB 23, Tempe TB 32, dan Tempe TB 55 sama dengan Tempe K. Demikian juga komposisi kimia Tempe TB 23, Tempe TB 32, dan Tempe TB 55 hampir sama dengan Tempe K.  Namun aktivitas antioksidan ketiga jenis tempe tersebut lebih tinggi dibandingkan dengan Tempe K. Tekstur, warna, dan komposisi kimia Tempe TB 23, Tempe TB 32, dan Tempe TB 55 bersama dengan Tempe K memenuhi syarat mutu tempe yang ditetapkan di Indonesia, yaitu yang tertera pada SNI 3144:2015. Oleh karena itu kesimpulannya adalah R. microsporus TB 23, R. microsporus TB 32, dan R. microsporus TB 55 memiliki potensi untuk dikembangkan sebagai laru komersial untuk fermentasi tempe.The Role of Some Strains of Rhizopus microsporus Originating from “laru tradisional” in Determining Tempe Quality AbstractThe quality of tempe was determined by involved microorganisms. The main microorganism in tempe fermentation is Rhizopus spp. which now generally comes from one type of commercial laru. As a result, the diversity of Rhizopus spp. in tempe has decreased. Therefore, this study aims to obtain information about the role of several strains of R. microsporus originating from "laru tradisional" in determining the quality of tempe. Tempe was produced using R. microsporus TB 23 (Tempe TB 23), R. microsporus TB 32 (Tempe TB 32), R. microsporus TB 51 (Tempe TB 51), R. microsporus TB 55 (Tempe TB 55), and tempe using commercial laru (Tempe K). The quality of tempeh was determined through measurements of texture, color, taste, antioxidant activity, and chemical composition (moisture content, fat content, protein content, and crude fiber content). The results showed that texture, color and taste of Tempe TB 23, Tempe TB 32, Tempe TB 55 were similar as compared to Tempe K. The antioxidant activity of the three types of tempe was higher than Tempe K. The chemical composition of the three types of tempeh was almost similar compared to Tempe K. Texture, color and chemical composition of Tempe TB 23, Tempe TB 32, Tempe TB 55 and Tempe K has fulfilled the quality requirements of tempe in Indonesia, which were listed in SNI 3144: 2015. Therefore, R. microsporus TB 23, R. microsporus TB 32 and R. microsporus TB 55 may be developed as commercial inoculums for tempe fermentation.

This work is the result of 3 years of collaborative research between Mississippi State Univ. and New Mexico State Univ. Physical, chemical, and sensory characteristics were studied to assess eating quality of popular New Mexico pecan (Carya illinoinensis) cultivars. The force and energy necessary to break (shear) pecan nuts, and Hunter `a' and hue angle values varied with harvest year and cultivar. All other traits, including sensory evaluation results, varied only with cultivar. `Ideal' was of light color, small size, and not as firm as the others, while `Burkett' was soft and slightly rancid. `Wichita' was the cultivar rated best by panelists, despite its slightly darker color. `Western Schley' and `Salopek' were also acceptable, although not as acceptable as `Wichita'.

The analysis of modern achievements in the technology of producing bread from triticalе flour using additives of vegetable origin has shown that the finished product is not always characterized by a balanced chemical composition caused by a low content of micronutrients, organoleptic indicators, uneven porosity of the crumb. Obtaining bread of increased nutritional and biological value is achieved due to the use of carrot powder and triticalе flour of the T-70 variety. The bread prepared accordingto the proposed method has improved physico-chemical parameters, which ensures the production of products of sufficient volume with a more elastic crumb and well developed porosity. To evaluate the quality of bread, generally accepted methods were used in the bakery industry. Protein content was determined by Kjeldahl titrimetric metod (GOST 13496.4–93), phosphorus was determined by vanado molybdate metod (GOST 26657–97), calcium content was determined by trilonometry metode with fluorexone (GOST 26570–95). Bread obtained using additives of plant origin is of interest from the point of view of chemical composition and can be considered as a product of therapeutic and prophylactic purpose.

AbstractExpansion of the Irish dairy herd has led to more dairy breed male calves being available for beef production. This study investigated the physico-chemical and sensory characteristics of beef from Holstein-Friesian (HF) and Jersey × HF (JEX) young bulls fed pasture grass only or pasture grass plus 2 kg concentrate during their first grazing season and slaughtered at 15, 19 or 22 mo of age. Longissimus thoracis (LT) muscles were collected from 67 carcasses. Postmortem pH, ultimate pH (pHu), meat colour, chemical composition, collagen content and solubility were evaluated. After ageing for 21 d, Warner-Bratzler shear force and cooking loss were determined, and assessments by a trained sensory panel were conducted. Meat from older animals was darker. The pHu, moisture and ash contents decreased, while residual roast beef flavour length increased with age. However, increasing age to slaughter did not negatively influence tenderness. JEX beef had lower cooking loss, was darker and redder, in addition to having higher sensory scores for initial tenderness and fattiness than HF beef. Warner-Bratzler variables were positively correlated with cooking loss and chewiness and were negatively correlated with intramuscular fat (IMF) content, soluble collagen and initial tenderness. In summary, most young dairy bull beef samples were acceptably tender after 21 d of ageing and half of them had acceptable IMF content. Slaughter age affected beef colour, pHu, chemical composition and flavour length. The eating quality of meat from the JEX breed type was considered to be superior to that of the HF breed type. Diet during the first season had no effect on meat quality traits.
