The possibility of buckwheat application in the fermented malt technology t

Rye is the traditional raw material for the fermented malt production. The article considers buckwheat grains application as an unconventional raw material. The research materials were rye of Vostok 2 breed and buckwheat of Dikul breed. Amylolytic capacity (AC) of malt was determined by colorimetric iodometric method, saccharification capacity (SC) - by polarimetric method, proteolytic (PC) - by refractometric method (according to Petrov); the humidity of the samples was determined on a thermographic infrared moisture meter FD 610. The extract, acidity and color of the fermented malt was determined according to GOST R 52061-2003. It was found that AC, SC and PC of buckwheat malt are 5.8% higher, 42.9% lower and 11.6% higher respectively than those of rye malt. Comparative characteristics of fermented buckwheat and rye malts showed that there is a decrease in the mass fraction of the extract and an increase in the color of buckwheat malt. This happens due to the hydrolysis of high-molecular compounds - carbohydrates, proteins to sugars and amino acids, respectively, due to the reactions of melanoid formation, which result in improved color, taste and aroma of malt. It was found that the use of buckwheat in fermented malt technology is possible, moreover, it is a gluten-free raw material due to the low content of the gluten fraction of the protein and can be applied to a wide range of consumers, including those suffering from gluten intolerance. But to increase its extractiveness, it is desirable to use enzyme preparations at the malting stage. The novelty of the proposed technical solution is confirmed by the RF patent for invention No. 2603268 "Method for the production of fermented buckwheat malt".

关于红外水分仪零位校准方式改进的建议

以异常值点双样的均值为零位校准的新标准，从总误差和误差标准偏差两个方面比较新旧标准，结果表明改进后的方法有效可以降低红外水分仪测量误差。 I will use the paired samples’ means of outliers as the new standard of zero calibration, and then compare the new and the old standard by total errors and standard deviation. The result shows that the improved method can effectively reduce the infrared moisture meter’s measurement error.

Improvement of Measurement Accuracy of Infrared Moisture Meter by Considering the Impact of Moisture Inside Optical Components

The impact of moisture inside internal end-face gaps of optical components on the measurements quality of infrared moisture meter for sulfur hexafluoride (SF6) gas-insulated equipment (GIE) is explored. The distortion of observed absorption line shapes occurs when the background absorption spectrum of moisture existing inside internal end-face gaps of optical components at atmospheric pressure is superposed on the desired absorption spectrum of moisture in SF6 GIE where the pressure exceeds 1 atm. Errors that arise with the measurements of moisture concentration and pressure because of line shape distortion effects in infrared absorption spectroscopy are quantitatively analyzed. A correction algorithm is proposed for the dual-beam balanced ratiometric detector strategy to improve the measuring precision. This algorithm eliminates the line shape distortion effects caused by moisture inside optical components and conducts a successful moisture measurement and control program for SF6 GIE. In our experiments, the impacts of moisture inside optical components have been suppressed, and the mean absolute errors have been decreased by 86.0% and 76.1%, respectively.

Study on Fruits Preservation in View of Surface Glossiness

Abstract: Nowadays, there is no low-cost fruit nondestructive testing method in China. The study aims to put forward a method about acquiring the moisture content of fruits indirectly by general photographic equipments. Firstly, general photographic equipment is used to obtain pictures of fruits or vegetables. Secondly, with the help of Matlab and Photoshop, the surface glossiness of the fruit or vegetable is gained. Thirdly, moisture content of a fruit or vegetable is measured through infrared moisture meter. Meanwhile, a Mathematical Model in Regression Analysis between the R value and the moisture content is established. Lastly, the non-linear relation between surface glossiness and moisture content of the fruit is found. Therefore, a new method about measuring the moisture content of fruits or vegetables through general photographic equipments is sought out.

A new technique for rapid and non-destructive measurement of rock-surface moisture content; preliminary application to weathering studies of sandstone blocks

The possibility of in situ rapid, non-destructive measuring of rock moisture content using an infrared optical moisture meter is examined. A laboratory test indicates that a linear relation is found between absorbance intensity of infrared rays and the moisture content of the surface of rock samples. The instrument was applied in the field in order to understand the weathering processes in sandstone blocks used for a masonry bridge pier better. The results show that the spatial and temporal changes in rock-surface moisture content are accurately measured, and that the infrared moisture meter is useful for weathering studies.

A New Method to Rapidly Assess the Stickiness of Cotton

Rapid assessment of the stickiness of cotton can be accomplished with a new apparatus designed, constructed, and tested at the U.S. Cotton Ginning Laboratory at Stoneville, Mississippi, and at a commercial laboratory. The apparatus essentially consists of a cabinet equipped with an infrared moisture sensor, resistance sensor, and compression platen. The apparatus may be used as a stationary laboratory device or it may be used for continuous, online monitoring in a gin or textile environment. The infrared moisture meter responds to the level of natural sugar and insect sugar that is contained within the sample whereas the resistance moisture content is affected only slightly. Results of several studies involving a number of cottons grown across the cotton belt indicated that the instrument can correctly estimate whether a sample is sticky or not about 75% of the time.

A portable infra-red moisture meter for agricultural and food materials: Part 1, instrument development

An instrument based on the near infra-red reflectance technique has been developed for on-farm rapid measurement of moisture content in grass and forage crops with potential application to other agricultural or food materials. The design of a portable, battery-operated self-contained robust instrument suitable for farm use has been made possible by the use of two light emitting diodes (LED) that emit radiation in the near infra-red spectrum as sources. The use of a complementary metal oxide silicon (CMOS) single chip microcomputer to control operation of the instrument and store calibration information has permitted the design of a self-contained instrument incorporating a read-out of moisture content. The paper describes development of the instrument. A second paper (Part 2) describes instrument evaluation and calibration.

A portable infra-red moisture meter for agricultural and food materials: Part 2, field evaluation on grass

A portable all solid state moisture meter based on the near infra-red reflectance technique, described in Part 1, was evaluated and calibrated for cut grass in the field. A linear relationship between grass moisture content and reflectance at a water absorption wavelength (1450 nm) was established for samples consisting of a randomly oriented mixture of stem and leaf. Calibration equations were obtained for four grass varieties at three stages of maturity. The overall accuracy of the instrument for measuring the moisture content of grass was approximately ±6.5% or better for a single point measurement over the range 40 to 80% moisture content (wet basis) pertinent to grass ensiling. The instrument operated satisfactorily over a wider range of moisture content (15–85%) but at reduced accuracy.

Measurement of Cotton Moisture with Infrared Sensors

AN infrared moisture meter was used to measure the moisture content of lint cotton by viewing the seed cotton during continuous gin processing. The meter accurately predicted the moisture of the lint in the seed cotton and demonstrated potential for incorporation into a moisture control system for gins and into a computer-controlled ginning process designed to maximize profits for the producer. Instrument accuracy was within 0.5 percentage points at lint moisture levels ranging from 4.4 to 10.1% and at seed cotton flow rates of 0.2 to 0.6 m/min.
