Parboiled rice is recognized for its greater milling yield and reduced rice breakage compared to raw rice during processing. Additionally, parboiled rice has better glycemic control and numerous health benefits. However, the production of parboiled rice requires energy-intensive processing as well as wastewater production. This study reviews parboiled rice, including its processing condition, nutritional properties, potential use, emerging green technologies, and health benefits. It also discussed the outlook and challenges regarding parboiled rice. In addition, a novel overview of emerging green solutions applied to the process to minimize wastewater creation during parboiling and reduce excessive energy usage is provided. The limitation of parboiled rice for a new market preference is the color. An intense process would cause an unwanted physical appearance. A thorough study should balance the multiple advantages of parboiled rice with the reasonable intensity of the process. Due to its multiple advantages, parboiled rice is demonstrated to be a possible breakthrough in the agriculture and food industries. This review aims to provide a thorough understanding that can be used for academic and industrial purposes.

“…The maximal zinc bioavailability (26.31%) was attained when GBR25 was germinated for 28 hrs. In addition, germination would boost parboiled rice's total phenolic content and antioxidant activity [107]. The enhancement of phenolic content can be accomplished by soaking in a floral extract rich in phenolics.…”

“…For instance, when maize seeds, a monocot plant, were administered with various concentrations of ZnO-NPs, the germination percentage was recorded at 100 mg/L with 87% on the eighth day of germination. Shoot length (12.1 cm), root length (20 cm), root and shoot width (1 and 2.8 mm) were detected (at the same concentration), compared to control [23].…”

Metal nanoparticles synthesized using various biosources are the subject of focus in many research areas thanks to their improved biological effects and increased bioavailability. Silver, zinc oxide and magnetite nanoparticles (NPs) were obtained by using low-cost, low-energy, environmentally friendly, non-toxic chemicals and easily accessible thyme leaves and lavender flowers, and its were characterized by using techniques UV-Vis, XRD, SEM and EDS. The effects of various concentrations of biosynthesized NPs on the germination and germination index of basil seeds were defined comparatively. Phytochemicals in lavender flower extract acted as reducing and capping agents in the biosynthesis of Ag-NPs, and phytochemicals in thyme leaves extract acted for the biosynthesis of ZnO-NPs ve Fe3O4-NPs. Relative root length was detected at 25 mg/L ZnO-NP, stem length at 50 mg/L ZnO-NP, and Relative seed germination 100 mg/L Fe3O4-NP with the maximum value. This research showed that the germination promoting effects of NPs, which may be essential microelements, are related to their size, surface area, morphology and concentration. Thus, it promoted early and rapid germination by breaking the NP's seed dormancy.

“…The nutrients of brown rice are far superior to those of white rice. At present, people adopt various ways to improve the nutritional value of rice, with germinated brown rice being the most common [ 33 , 34 , 35 ]. Brown rice germination promotes the increase in a variety of bioactive compounds, including gamma-aminobutyric acid (GABA) and antioxidants [ 36 , 37 , 38 ].…”

The present study investigated the dynamic changes in vitamin E and gene expression within its biosynthetic pathway during three germination periods of four brown rice cultivars with different seed coat colors. The results reveal that the vitamin E content increased during the germination process of all brown rice cultivars. Moreover, the content of α-tocopherol, α-tocotrienol, and β-tocopherol significantly increased at the later stage of germination. The expression levels of DXS1 and γ-TMT genes in all cultivars were significantly increased, whilst the HGGT gene expression levels of G6 and XY cultivars increased significantly at the later stage of brown rice germination. In addition, the expression levels of MPBQ/MT2 in G1 and G6 cultivars, and TC expression levels in G2 and G6 cultivars were substantially increased at the later stage of germination. Overall, the up-regulation of MPBQ/MT2, γ-TMT, and TC genes doubled the content of α-tocopherol, α-tocotrienol, and β-tocopherol, and the total vitamin E content of brown rice was at its highest at 96HAT. The utilization of the germination period can effectively improve the nutritional value of brown rice, which can be used for the development and utilization of brown rice for healthy rice products.
