Soaking Effects on Physical Characteristics of Basmati (Pusa Basmati 1121) Rice CIGR Journal
KALE, SAKHARAM; JHA, SUNIL KUMAR; NATH, PRERNA.
PB1121 paddy was soaked in water at seven different temperatures (40-80oC) till it achieved desired moisture. Soaking showed significant effect on physical characteristics of PB1121 rice. Soaking altered the length, breadth, thickness volume, surface area, equivalent diameter and sphericity of of paddy grain. Un-soaked grains had bulk and true density as 508.60 and 1138.8 kg/m3, respectively whereas that of soaked grains varied from 511-527 and 1188-1238 kg/m3, respectively. HRY of un-soaked rice was 42.12% whereas that of soaked rice varied from 50.21-53.05%. Soaked grains were harder than the un-soaked grains. Un-soaked rice had lightness and redness values as 60.26 and 6.47, respectively but, with soaking temperature, lightness decreased (9.56-16.23%)...

Application of the Hsu model to soybean grain hydration Ciênc. Tecnol. Aliment.
Coutinho,Mônica Ronobo; Conceição,Wagner André dos Santos; Paraíso,Paulo Roberto; Andrade,Cid Marcos Gonçalves; Omoto,Edilson Sadayuki; Jorge,Regina Maria Matos; Maciel Filho,Rubens; Jorge,Luiz Mario de Matos.
A comparative analysis of the theoretical-experimental study, developed by Hsu on the hydration of Amsoy 71 soybean grain, was performed through several soaking experiments using CD 202 soybean at 10, 20, 30, 40, and 50 °C, measuring moisture content over time. The results showed that CD 202 soybean equilibrium moisture content, Xeq, does not depend on temperature and is 21% higher than that found by Hsu, suggesting that soybean cultivar exerts great influence on Xeq. The Hsu model was numerically solved and its parameters were adjusted by the least squares method, with maximum deviations of +/- 10% relative to the experimental values. The limiting step in the mass transfer process during hydration corresponds to water diffusion inside the grain, leading...

FUZZY SLIDING-MODE TEMPERATURE-CONTROL SYSTEM FOR SOAKING AND GERMINATION OF RICE SEEDS REA
Zhou,Zheng; Liang,Chunying.
ABSTRACT The soaking and germination process of rice seeds is the starting point in rice cultivation in cold regions and has a significant effect on grain yield. Efficient techniques for controlling the water temperature in the seed tank are required to enhance germination quality. This paper introduces a fuzzy theory for designing a fuzzy logic-based sliding mode controller (SMC) system for a rice seed soaking and germination device. The proposed system was theoretically and experimentally investigated to determine the efficiency of the soaking temperature-control system. A modified fuzzy SMC based on exponent approaching law is also presented for optimizing the proposed controller. A proportional integral derivative (PID) controller was designed to...

Germination conditions influence the physical characteristics, isoflavones, and vitamin C of soybean sprouts PAB
Silva,Mariah Benine Ramos; Leite,Rodrigo Santos; Oliveira,Marcelo Álvares de; Ida,Elza Iouko.
Abstract: The objective of this work was to evaluate the effects of the germination conditions of 'BRS 216' soybean (Glycine max) on the length, yield, and isoflavone contents of sprouts. A 23 factorial arrangement was used to evaluate the variables soaking time, irrigation frequency, and germination time. Sprouts that showed better length and yield and higher isoflavone contents were evaluated for their chemical composition and vitamin C content. Soaking and germination time of soybean showed a positive and significant linear effect on sprout length. However, only germination time showed a significant positive linear effect on yield, and a significant negative linear effect on the content of malonylglycosides, aglycones, and total isoflavones. Soybean...

Methods to promote Borreria latifolia seed germination Rev. Ciênc. Agron.
Gallon,Mateus; Trezzi,Michelangelo Muzell; Diesel,Francielli; Possenti,Jean Carlo; Batistel,Sorhaila Camila.
ABSTRACT Specific knowledge on dormancy and germination patterns of weed species aids the development of integrated management strategies. This study aimed to evaluate and select effective methods for overcoming dormancy in B. latifolia seeds, as well as determining their influence on the germination process. A completely randomized experimental design was used, with four replications and 20 seeds per repetition. Seven tests were conducted, with the corresponding B. latifolia seed treatments: Test 1 - mechanical scarification, sulfuric acid, hot water and running water; Test 2 - pre-cooling at 4 °C and dry heat at 60 °C. Test 3 - gibberellic acid at concentrations of 0, 50, 100, 200 and 400 ppm; Test 4 - acetic acid and potassium nitrate 2%; Test 5 - dual...
