Effect of Parboiling Rough Rice on Milling Quality (Classic Reprint)


Book Description

Excerpt from Effect of Parboiling Rough Rice on Milling Quality The available evidence shows that parboiled rice has desirable characteristics that are at present entirely unknown In the rice trade of the United States. Suitable equipment for parboiling rice on a commercial scale probably Is now available or can easily be designed in this country. The consumption of rice in the United States very probably could be materially increased by supplying the market with high-quality parboiled rice, which, according to all the evidence, is better In cooking quality and In flavor.

Rice Quality


Book Description

Rice is a unique and highly significant crop, thought to help feed nearly half the planet on a daily basis. An understanding of its properties and their significance is essential for the provision of high quality products. This is all the more true today as international trade in rice trade has been increasing rapidly in recent years. This important book reviews variability in rice characteristics and their effects on rice quality.After an introduction on rice quality that also explores paradoxes associated with the crop, the book goes on to examine rice physical properties and milling quality. This leads to a discussion of the effects that the degree of milling has on rice quality. The ageing of rice and its cooking and eating quality are investigated in the following chapters before an analysis of the effect of parboiling on rice quality. Later chapters consider the product-making and nutritional quality of rice and investigate speciality rices and rice breeding for desirable quality. The book concludes with an extensive chapter on rice quality analysis and an appendix containing selected rice quality test procedures.With its distinguished author Rice quality: a guide to rice properties and analysis proves an invaluable resource for professionals in the rice industry and researchers and post-graduate students interested in rice. Examines the physical properties of rice, such as grain appearance and density and friction Investigates the ageing of rice and its cooking and eating quality The product making and nutritional aspects of rice are also considered
















Effect of Parboiling and Related Treatments on the Milling, Nutritional, and Cooking Quality of Rice (Classic Reprint)


Book Description

Excerpt from Effect of Parboiling and Related Treatments on the Milling, Nutritional, and Cooking Quality of Rice Three varieties of rice grown under like conditions in Texas in 1943 were pretreated before milling by 12 different methods, and the effect of the treatments on milling quality, thiamine content, and cooking and canning qualities was determined. The average increase in head rice yield in the three varieties was 8 percent for the siddha, sela, and josh treatments, and 26 percent for the eight parboiling treatments.

Effect of Germination and Parboiling on Milling, Physicochemical, and Textural Properties of Medium- and Long-grain Rough Rice


Book Description

Germinated brown rice is commonly consumed in Asia for its enhanced nutritional properties such as gamma-aminobutyric acid (GABA) and softer cooked texture. However germination decreases milling yield and alters some physicochemical properties, and most germinated rice studies evaluated medium-grain and aromatic rice cultivars. This study compared the effects of germination duration and parboiling on milling, physicochemical, and textural properties of a medium- (Jupiter) and a long-grain (Wells) rice cultivars. Rough rice was soaked in water at 25°C for 12 hr, and then incubated at 30-34°C for varying germination durations, or combined with parboiling at 120°C for 20 min prior to drying. Germination resulted in an increase in brokens and a decrease in kernel weight for Wells. Parboiling increased milling yield and GABA content but decreased kernel whiteness and pasting profiles for both cultivars. Jupiter was consistently higher in soluble sugars, ash, and GABA content with germination progression compared with Wells. There were no significant changes in gelatinization temperatures and pasting properties between germination durations for parboiled and non-parboiled rice. Germination decreased cooked rice hardness of Wells and cooked rice stickiness of Jupiter for both non-parboiled and parboiled samples. Parboiling increased GABA content and cooked rice softness for both cultivars. The impacts of germination and subsequent parboiling on milling, physicochemical, and textural properties of rice were affected by grain type and germination duration.
