Equilibrium moisture content (EMC)/equilibrium relative humidity (ERH) studies pertaining to rice and rice products were reviewed. Methods of determining rice and rice component EMC/ERH data varied, using procedures involving static and dynamic equilibration methods, as well as direct gravimetric methods and indirect ERH‐measurement methods. Methods for measuring rice and rice component moistur...

The morphology and photosynthetic enzyme activity were studied in maize phosphoenolpyruvate carboxylase transgenic rice and non-transgenic rice. The results showed that compared with non-transgenic rice, phosphoenolpyruvate carboxylase transgenic rice was taller and had a stronger stalk, wider leaves, and more exuberant root system, with increased photosynthetic enzyme activity and improved yie...

Calcium–fortified rice is normal rice fortified with calcium and processed by consecutive steps, i.e. infusion or soaking of the rice grain in a calcium salt solution, draining and drying. Heating during infusion causes pregelatinization of rice starch resulting in a change in the pasting properties of Ca-fortified rice. Pasting properties determine the cooking quality of rice. The purpose of t...

Aroma intensity in rice is related to the level of 2-acetyl-1-pyrroline (2AP). The accumulation of 2AP in rice has been synthesized via l-proline metabolism by inactive betaine aldehyde dehydrogenase enzyme (BADH2), which activates 2AP accumulation. Meanwhile, active BADH2 inhibits 2AP accumulation but activates γ-aminobutyric acid (GABA) accumulation. The improvement of 2AP content in rice has...

This study aimed to explore the ecological adaptability and the possibility of growing rice with floating bed on the dilute biogas slurry. The results of the experiments show that the growth stage, rice plant height, and rice yield and quality were significantly affected by multiple dilutions; rice plants cultivated with 45 multiple dilutions had better ecological adaptability than others. In t...

Head rice rate is an important factor affecting rice quality. In this study, an inflection point detection-based technology was applied to measure the head rice rate by combining a vibrator and a conveyor belt for bulk grain image acquisition. The edge center mode proportion method (ECMP) was applied for concave points matching in which concave matching and separation was performed with collabo...

Starches from six wild rice cultivars were studied for their chemical structures and physicochemical properties and compared with a long-grain rice starch. The six wild rice starches were similar in morphological appearance, X-ray diffraction patterns, swelling power, and water solubility index but different in amylose content, beta-amylolysis limit, branch chain length distribution, thermal pr...

This paper proposes machine algorithm to grade (Premium, Grade A, Grade B and Grade C) the rice kernels using Multi-Class SVM. Maximum Variance method was applied to extract the rice kernels from background, then, after the chalk has been extracted from rice. The percentage of Head rice, broken rice and Brewers in rice samples were determined using ten geometric features. Multi-Class SVM classi...

Introduction Proper potassium (K) nutrition is critical for maximizing rice grain yields. K is very mobile within the rice plant. Older leaves are scavenged for the K needed by younger leaves. Recent studies at the Missouri Rice Research Farm have shown that supplemental K can be supplied to the rice plant as late as Internode Elongation (IE) and still increase rice grain yields. In this same s...

Cultivation of Pleurotus ostreatus on different substrates such as rice straw, rice straw + wheat straw, rice straw+ paper, sugarcane bagasse and sawdust of alder was investigated. All the substrates except rice straw were supplemented with 10% rice bran. The substrate without supplement was considered as control. The effects of various substrates on mycelial growth, colonization time, primordi...
