Demineralization is required to reduce the ash content of gelatin. Previous studies have confirmed the high quality of gelatin was produced after demineralized using combination of NaCl and aqueous NaOH. The purpose of this study was to determine the effect of NaCl on the properties of gelatin from Lizardfish (Saurida spp.) scales. The cleaned scales was demineralized using a mixture of NaOH 0.5% and NaCl (0- 0.8%), at various temperatures (45, 65, 86oC) and time (30, 60, 90 and 150 minutes). The obtained samples was determined by ash content, pH, the lightness and moisture content. Addition of NaCl reduced the ash, pH and moisture content but increased the whiteness. Gelatin physical properties increased inline with NaCl concentration. Extended demineralized period gave a positive effect on ash, pH and moisture content but opposite effect was observed in the lightness and physical properties. Extended demineralization periods in high temperature reduced gelatin quality. The highest gel strength was found at demineralization for 150 min at 65oC using a combination of NaOH 0.5% and NaCl 0.8%. At this condition, the gelatin has 10%, 1,7%, 248 bloom, and 7,1 cP of moisture content, ash, gel strength and viscosity, respectively, which fulfil SNI 06.3735.1995.

ABSTRACT: This study aimed to evaluate the quality of forest biomass energy, coming from the Caatinga, for different storage times in the field. The study was conducted in southern Piauí, between January and February (rainy season). Samples were collected containing branches and trunks of various species, and samples of branches and trunks separately in 5 sample units of 20x20m. Samples were evaluated in the general state freshly harvested and samples of branches and logs after 15 and 30 days of storage in piles in the field. The analyzes carried out were: moisture content on wet basis, ash content and calorific value. Moisture content of freshly harvested biomass ranged from 39% with two days after cutting to 79% in biomass cut and left distributed in the field for 10 days. After storage in piles for 15 days, branches showed moisture content of 18% and the logs 21%, and net calorific value of 3432kcal kg-1 and 3274kcal kg-1, respectively. After 30 days, moisture content for branches was 13% and the logs 21%, and net calorific value of 3672kcal kg-1 and 3240kcal kg-1, respectively. Ash content of the biomass was low. Cutting trees in the rainy season, with maintenance of biomass in the field for 10 days, resulted in an increment of moisture content. Branches had the best behaviour during the storage. Fifteen days of storage are sufficient for the caatinga biomass to achieve high-quality energy.

Wild sunflower with moisture contents of 16%, 12% and 8% was densified without the addition of binding agent. The physical properties of the formed briquettes such as mass, dimensions, volume, density and shattering resistance were evaluated. Thermal properties like ignition time, burning time, ash content, and thermal fuel efficiency by means of boiling test were also evaluated. Wild Sunflower stems were gathered and shredded using locally fabricated biomass shredder available at the Research Office of Benguet State University, and were processed into the desired size and moisture contents. Right after the briquetting operation, the physical properties of the briquette were measured and then stored in a zip bag for 24 hours. After the storage, same measurement was conducted. Results show that the influence of moisture contents on the average mass, dimension, shattering resistance, volume and density was statistically insignificant. The wild sunflower with moisture content of 16% had the highest shattering resistance of 88.85%. Furthermore, the influence of moisture content on the thermal properties like ignition time, burning time and ash content are statistically insignificant. Among the moisture contents, the fastest ignition time of 43.75 sec with longest burning time was recorded under 12%. Ash content was also lowest at 12%.

The drying process of corn noodles was an effort to increase the shelf life and it was a form of noodles diversification. The objective of this research was to study and analyze the effect of guar gum addition on the physical quality of the extruded dry corn noodle made from a mixture of wet and dry corn flour. Manufacturing dry corn noodles was conducted using wet corn noodles from a mixture of wet and dry corn flour, which was then dried in a tray dryer at a temperature of 60-70 °C for 1 - 1.5 hours. The treatments used were a combination of alum levels of 0.01%; moisture content of 80% (dry base); and guar gum concentration of 0%, 1%, and 2%. Physical properties of dry corn noodles included rehydration time, hardness, adhesiveness, suppleness, elongation, and cooking loss. The results showed that the optimum rehydration time for dry corn noodles was about 9 minutes. The addition of guar gum to the physical qualities of dry corn noodles tended not to be significant statistically, but as a score, an increase in guar gum levels tended to increase the elongation of dry corn noodles. While, increasing levels of guar gum tended to reduce the stickiness and cooking loss levels of them.

Применение протравливателей семян способствует повышению их полевой всхожести, снижению головневых заболеваний и корневых гнилей. Опыт эксплуатации протравливателей в зерносеющих хозяйствах показал, что в Российской Федерации наибольшее распространение получили самоходные протравливатели камерного типа ПС-20АМ01, Mobitox Super, ПСК-15. Недостатки этих машин выражаются в невозможности проведения качественного протравливания на площадках с углом наклона более 7 градусов и при работе машины при производительности в диапазоне от 60 до 100 от базовой. Кроме того, повышенные влажность семян после протравливания (по агротехническим требованиям АТТ не более 1 ) и дробление семян несколько снижают эффективность применения камерных протравливателей. Целью исследований являлось повышение качества протравливания семян за счет применения двухдискового распределяющего и двухуровневого отражающего устройств. Для чего сравнительные исследования протравливателя Mobitox Super, оснащенного двухдисковым распределяющим устройством и двухуровневым отражающим устройством семян, проводили с базовым вариантом Mobitox Super в ООО Русское поле Сердобского района Пензенской области на обработке семян озимой пшеницы Бирюза комбинированным инсектофунгицидным протравителем семян Селект Макс с нормой расхода препарата 1,7 л/т. Установлено, что в диапазоне от 30 до 150 мм открытия заслонки лепесткового дозатора разработанного камерного самоходного протравливателя качество протравливания семян значительно увеличивается в сравнении с серийно-выпускаемым Mobitox Super и увеличивается его производительность до 2,1 т/ч.The use of seed dressers improves their field germination, reduces smut diseases and root rot. The experience of the use of dressing agents in grain-sowing farms showed that the self-propelled seed dressers PS-20AM01, Mobitox Super, PSK-15 are most widely used in the Russian Federation.The disadvantages of these machines are expressed in the impossibility of conducting high-quality dressing on sites with an inclination angle of more than 7 degrees and when the machine is operating at a capacity in the range from 60 to 100 of the base. In addition, the increased moisture content of the seeds after dressing (according to the agrotechnical requirements of perfectly rigid body (PRB) - no more than 1 ) and the crushing of seeds somewhat reduce the effectiveness of using chamber dressers. The aim of the research was to improve the quality of seed dressing through the use of a two-disk distributing and a two-level reflecting devices. We conducted comparative studies of the Mobitox Super seed dresser, equipped with a two-disk distributor and a two-level seed reflector, with the basic version of Mobitox Super. The studies were carried out in the OOO Russkoye Polye of Serdobsky district of the Penza region on the treatment of winter wheat Biryuza seeds with a combined insectofungic seed dresser Select Max with a consumption rate of 1.7 l/t. It was established that in the range from 30 to 150 mm of opening the spade-type dispenser flap of the developed chamber self-propelled seed dresser, the quality of seed dressing significantly increased and its productivity increased to 2.1 t/h in comparison with the commercially available Mobitox Super.
