AbstractMicrocrystalline cellulose (MCC) is a semi-crystalline material with inherent variable crystallinity due to raw material source and variable manufacturing conditions. MCC crystallinity variability can result in downstream process variability. The aim of this study was to develop models to determine MCC crystallinity index (%CI) from Raman spectra of 30 commercial batches using Raman probes with spot sizes of 100 µm (MR probe) and 6 mm (PhAT probe). A principal component analysis model separated Raman spectra of the same samples captured using the different probes. The %CI was determined using a previously reported univariate model based on the ratio of the peaks at 380 and 1096 cm−1. The univariate model was adjusted for each probe. The %CI was also predicted from spectral data from each probe using partial least squares regression models (where Raman spectra and univariate %CI were the dependent and independent variables, respectively). Both models showed adequate predictive power. For these models a general reference amorphous spectrum was proposed for each instrument. The development of the PLS model substantially reduced the analysis time as it eliminates the need for spectral deconvolution. A web application containing all the models was developed.

Lemon growing areas in the north of Argentina have industries that produce concentrated juice, peel and essential oil and generate a significant amount of liquid and solid waste as lemon pulp. In Argentina, despite the potential applications that the pulp has as animal feed and human and industrial raw material, only 10% is used for these purposes and the rest is discarded into the environment causing many ecological and economic problems. There is little information in the literature on biotechnologies for the treatment of this industrial waste. This paper shows that lemon pulp is a suitable substrate to be treated by anaerobic digestion. We obtained 86 and 92% reduction of chemical oxygen demand in a digester with a semi-continuous feed and retention time of 10 and 20 days respectively and a productivity of 0.406 g CH4/g VS h. Comparative tests showed that pre-digesting the pulp improved the process of digestion and increased biogas generation by 20%.

Tomato comes as the most commonly produced, consumed and subject for trading in the world. Alongside fresh consumption, on the other hand it forms the most significant raw material source of food industry, especially for tomato paste, frozen and dried vegetable-fruit and canned food industry. Turkey's greenhouse vegetable production field for 2016 year is 675173 decars and Antalya forms 51% of this field. Tomato forms 61.72% of Antalya's greenhouse production. The main material of the research consists of interviews made with producers resided in 5 villages/towns, where greenhouse tomato production is carried out densely in Antalya city, Alanya district. In 48 villages and towns, greenhouse tomato production is carried out, according to the official records. In the chosen areas, 365 producers exist. 20% of these producers (73) form the sample size. In the research, it was determined that the producers' average agricultural land possession is 9.13 decars and in 40.53% of these areas they grew tomatoes. None of these producers are engaged in contractual growing. All of the yield is produced for the edible (as table-top item). After the harvest, all of the products are sold in the wholesales market in county and city. 7.89% of the producers have no information on soilless agriculture, as 10.52% of them think that it has no advantages and 73.36% of them recommend traditional agriculture.

In the farms of the north-eastern slope of the Greater Caucasus wood raw material obtained from intermediate felling, is not fully utilized and is not effective, due to the organizational and technical difficulties of farms. In addressing these issues in 8 directions of the region with a length of 40-50 km 14 intermediate assembly points were organized, which are intended for the collection and temporary storage of wood raw material harvested within a radius of 15-20 km of the forest. Need to establish assembly points is due to the complexity of relief items and the possibility of year-round use of the main roads of regional importance. To ensure uninterrupted timber industry and in full at the assembly point accumulated wood raw material is partially sorted. Processing of harvested wood raw material is planned for timber industry, located near the central region of the main road in the territory of Cuba town. Establishment in the area of the complex is considered justified, since the resource base in the coming years for intermediate, and later for the main use will be more than 100 thousand hectares of forests in the region. In the proposed area for the industrial complex for processing of raw wood there are all the technical and economic prerequisites. Accumulated in the assembly points wood raw material to the point of processing is transported using self-loading lumber carriers of up to 8 meters length, which is associated with a complex terrain conditions and road network in the region. This complex is planned to organize the following process areas: sawmills, parquet and packaging, small-chip technology, processing of technical greenery. In organizing the production sites size and quality characteristics and volumes of each category of harvested wood raw materials are taking into account, as well as the need for forest products in the region and the country as a whole. In the processes it is envisaged to use the most advanced modular processing of wood with the release of standard lumber, wood workpieces of different products, pulp chips, wood greens and products of its processing.

During the research conducted at the All-Russian Research Institute for Starch Products there has been developed a technological mode of using cellulolytic enzymes to reduce the viscosity of grain pulp obtained by grinding naked oat grains soaked in a sodium metabisulphite solution. As the experimental data had been processed, the optimum technological parameters of the process were determined: the consumption of the enzyme preparation Viscoferm was 200 g/t of grain and the dura-tion of fermentation by constant stirring for 2.5 hours at pH 4.6 and temperature 50°C. Under laboratory conditions there has been studied the possibility of starch processing of naked oat grain samples Vyatka, Percheron, 857h05, 766 h05 varieties grown in the Federal Agricultural Research Center of the North-East named N.V. Rudnitsky. Technological assessment based on grain processing in the laboratory using the “plant on the table” method has shown that the yield of coarse-grained starch A in the processing of naked oat using cellulolytic enzymes is 51.4-53.9%, i.e. higher than that of filmy oats, rye Falenskaya 4 and Vyatka 2, wheat and triticale. Low starch content in fiber (7.7-8.7% dry substances DS of fiber) was found in comparison with the results obtained from the processing of filmy oats, Falenskaya and Vyatka 2 rye varieties, wheat and triticale (11.2 - 13.9% DS of fiber). Fiber output by the processing of naked oats is 7.3 - 8.8% DS of grain, by the processing of other types of grain 10.3 - 17.5% DS of grain. The yield of small-grain starch B in the processing of the studied varieties of naked oat is 19.2 - 20.8% DS of grain, that is higher than this value obtained by processing of filmy oats and wheat, but lower than by pro-cessing of rye and triticale. Isolated carbohydrate-protein concentrate, including starch B and proteins, is recommended for use with the extract and fiber as a component for the production of feed.
