“…In addition, the liberated lignin and carbohydrate parts can be decomposed to the other smaller components by subcritical water hydrolysis reactions (i.e. phenolic compounds and soluble sugars, respectively) [17,42,43] in subcritical water medium.…”

“…Recently, it was reported that when rice bran was treated with subcritical water at between 200 and 220°C for 30 min, greater than 90% of the protein could be recovered in a soluble form with limited hydrolysis [17][18][19][20][21][22]. During the subcritical water processing, the ionization constant of water (K w ) increases from 1 9 10 -14 at ambient temperature to around 7 9 10 -12 at 220°C.…”

Because of the large amount of rice produced annually, milled rice co-products, such as rice flour, rice bran, rice bran oil, wax, and rice hulls are plentiful and readily available. These co-products are valuable sources of food ingredients, but they are currently under-utilized. Rice bran and flour contain different levels of protein.When treated with carbohydrate-hydrolyzing enzymes, high-protein products can be produced, which are nutritious and used widely in health and baby food formulations. Recently, subcritical water processing has also been studied, in which water is put under high pressure to maintain its liquid state and used as an environmentalfriendly media for the recovery of rice bran proteins. Rice flour contains more than 90% rice starch (RS), and functional properties of RS are normally modified to suit the needs for food applications. For example, the addition of small amounts of phosphorylated RS esters or pregelatinized rice flour to frying batters made of rice flour was found to impart superior sensory characteristics and lower the amount of oil-uptake. Reductions in oil uptake of up to 50% were observed with the rice based formulations compared with batters made from traditional wheat ingredients. Treatment of RS with octenylsuccinic anhydride produces modified starch products that are useful as an emulsifying agent for the encapsulation of lipophilic compounds. Similarly, other rice-based products, such as microcrystalline celluloses from rice hulls, edible films formed with rice wax, various components with antioxidant properties, and germinated brown rice flours have also been developed.

“…Current research on cellulose production is directed toward reducing or ruling out the use of polluting chemicals [9,10]. Besides, a search is being performed for selective separation of the major components of lignocellulosic biomass (cellulose, lignin, and hemicellulose) in slightly degraded forms in order to produce high-value products.…”

Enzymatic hydrolysis of cellulosic raw materials to produce nutrient broths for microbiological synthesis of ethanol and other valuable products is an important field of modern biotechnology. Biotechnological processing implies the selection of an effective pretreatment technique for raw materials. In this study, the hydrotropic treatment increased the reactivity of the obtained substrates toward enzymatic hydrolysis by 7.1 times for Miscanthus and by 7.3 times for oat hulls. The hydrotropic pulp from oat hulls was more reactive toward enzymatic hydrolysis compared to that from Miscanthus, despite that the substrates had similar compositions. As the initial substrate loadings were raised during enzymatic hydrolysis of the hydrotropic Miscanthus and oat hull pulps, the concentration of reducing sugars increased by 34 g/dm(3) and the yield of reducing sugars decreased by 31 %. The findings allow us to predict the efficiency of enzymatic hydrolysis of hydrotropic pulps from Miscanthus and oat hulls when scaling up the process by volume.
