Definitions
- the present invention relates to a process to extract proteins mildly from (preferably defatted) rice bran by limited proteolysis.
- the rice bran is washed before being subjected to limited proteolysis.
- Protein extraction of agro-sources can be hampered by the solubility of the proteins itself or their interactions in the matrix with other constituents.
- the solubility is on its turn influenced by the processing steps before protein harvesting. For example, defatting of the material decreases the solubility of the proteins drastically. Therefore, the technique of proteolysis is applied to increase the solubility of the proteins and thus the protein extraction yield.
- the use of proteolytic enzymes mostly results in a bitter tasting product due to a high degree of hydrolysis with limited applications in food.
- Rice bran is a by-product of the rice milling process. Generally rice milling yields about 15 weight percent (wt%) broken kernels, about 10 wt% rice bran, about 20 wt% hulls and about 55 wt% whole kernels. The typical protein content of rice bran is about 14 wt%. Other components in rice bran are moisture (about 10 wt%), crude oil (about 20 wt%), total dietary fiber (about 18 wt%), starch (about 22 wt%), ash (about 8 wt%) and other components (about 8 wt%). A valuable product obtained from the rice bran is rice bran oil which is the oil extracted from the germ and bran layer.
- defatted rice bran After oil removal, a defatted product remains which is usually used in feed applications.
- the fat content of defatted rice bran is typically lower than 5 wt%. It is estimated that yearly more than 70 million ton of rice bran is produced, which still contains several valuable components, like proteins.
- Extraction of rice bran proteins has been published in literature. Extraction methods include the use of water at alkaline conditions and/or the use of several carbohydrases (like amylases) sometimes in combination with the enzyme phytase. It is known that extraction of proteins from the non-treated rice bran is difficult. However, in case of defatted rice bran, protein extraction is even a more harsh task due to the heat treatment during oil extraction and especially during the toasting process to remove the residual hexane with protein denaturation as consequence.
- US201 1/0152180 describes bioactive pentapeptides from heat stabilized defatted rice bran.
- US 2011/0152180 uses Alcalase which is a very active enzyme and as a consequence leads to a strong protein degradation when incubated with different rice bran sources. According to example 1 of US 2011/0152180, the optimal degree of hydrolysis is 23,4%.
- Alcalase 2010, As J Food Ag-lnd 3(02), 221-231 ) describe conditions for rice bran hydrolysate production using Alcalase.
- the present invention provides a (preferably defatted) rice bran hydrolysate composition which comprises of more than 50 wt% (on dry matter) of (poly)peptides and which has a DH (Degree of Hydrolysis) of at least 10%, preferably between 10 and 16% and more than 90%, preferably more than 95%, of the (poly) peptides has a molecular weight (MW) of more than 500 Da.

- the technique of washing and mild hydrolysis is preferably applied on defatted rice bran.
- the process described is valid also/applicable for other rice bran sources such as raw rice bran and heat stabilized rice bran.
- a process is provided based on a limited or mild hydrolysis preferably followed by a solid/liquid separation. Both the liquid and the insoluble stream may be further dried.
- An advantage of this protease treatment followed by separation is that a solid fraction (pellet) is obtained with a high amount of total dietary fiber which can also be used in various food applications.
- rice bran is meant the hard outer layer of rice which consists of combined aleurone and pericarp. Along with germ, it is an integral part of whole rice, and is often produced as a by-product of milling in the production of refined rice.
- Raw rice bran is rice bran as obtained after milling.
- defatted rice bran is meant rice bran of which at least part of the oil present is removed by for example extraction. Oil extraction is for example performed with hexane at approximately 60-65 degrees Celsius while the detoasting for hexane removal is typically performed at 1 10 degrees Celsius.
- stabilized rice bran is meant rice bran which after milling is typically being stabilized at 130 degrees Celsius during ⁇ 10 seconds.

- rice bran several studies exist to obtain the protein fraction using enzymes in addition to the more widely applied alkali extraction techniques see for example US201 10305817.
- the use of proteases is generally more successful compared to the use of carbohydrases (see for example the review of Fabian and Ju (A Review on rice bran protein: its properties and extraction methods, Critical Reviews in Food Science and Nutrition, 201 1 , vol. 51 , 816-827) summarizing enzymatic methods).
- Fabian and Ju A Review on rice bran protein: its properties and extraction methods, Critical Reviews in Food Science and Nutrition, 201 1 , vol. 51 , 816-827) summarizing enzymatic methods).
- Several proteases have been investigated in literature to obtain higher protein extraction yields (compared to carbohydrases). These hydrolysis products are usually bitter tasting hydrolysate compositions which cannot be widely applied in foods.
