Rye bran

The foamability of the xylans tested [128] was low in comparison to a commercial whipping protein DIOO. Only the highly viscous beech wood xylan and the rye bran AX-protein complex exhibited remarkable foaming activity, which was similar to that of gum arable. As the MGX polymers contain considerable amounts of uronic acid side chains, this may play a role in their foaming activity together with the presence of low amounts of Ugnin.

When the cereal media are used, e.g., ground rye, rye bran, etc., growth is allowed to proceed as far as possible in order that the material may be almost completely utilized by the fungus. The mass is then dried, ground if necessary, extracted and tested exactly as for crude drug.

This chapter focuses on the use of different methods for isolation of alkylresorcinols. Alkylresorcinols are members of a lipid group called non-isoprenoid phenolic lipids. Different aspects of the extraction by classical methods and supercritical CO2 are discussed. Supercritical CO2 extraction of alkylresorcinols from rye bran is discussed for the first time. As compared to the classical extraction methods, supercritical CO2 gives higher yields and it allows the separation of the crude extrac into long- and short-chain alkylresorcinol homologues. 

No significant difference was achieved in the crude extract amounts by using either ethanoi or methanol. Ethanol should however be preferred as it is an acceptable solvent in food preparation. Process optimization of the extraction of AR from rye and other sources, especially cereals needs still to be performed. The most common AR homologues in rye bran differ in only two carbon atoms, therefore their solubility in supercritical CO2 is expected be very similar. The possibility of separating individual AR homolgues using supercritical CO2 will present future additional challenges.

Most of the rye grown in the UK is used for the production of rye breads and speciality products for human consumption. Some is used for brewing and distilling. The offals from the production of rye malt are rye bran and rye malt culms, but these are available in such small amounts in the UK as to be of httle importance.

Preparation 35). Mesquite gum, from a plant Prosopis juliflora and related species) common in the southwestern United States, and cherry gum are utilized. Mesquite gum consists of L-arabinose, D-galactose, and 4-0-methyl-D-glucuronic acid in combination, and cherry gum in addition has some D-xylose and D-mannose. By controlled hydrolysis most of the pentose is removed without hydrolyzing the other constituents to any great extent. The L-arabinose is then partially purified by dialysis 36) or ion-exchange procedures 37) and crystallized from ethyl alcohol. Wheat and rye bran, peach gum, Australian black wattle gum, and spent beet pulp have been utilized for the preparation of L-arabinose.

Many fruits and vegetables (e.g., grape, citrus, olive, black pepper, spices, soya, cereals) and the derived foods and beverages are a good source of phenolic antioxidants and constitute an important part of our daily diet [4,5,25,26,107-109,111-115]. A good correlation between phenolic content and antioxidant activity is often observed, as reported for monomeric and dimeric hydroxycinnamates of rye bran [75] and various caffeoyl quinic esters in peach puree [116],... 

More recently, the quartemization of xylan isolated fh)m beech wood, com cobs, and rye bran was investigated (15), The reactions were carried out with a sodium hydroxide activated xylan and CHTMAC as alkylating reagent. The results show clearly that the DS of TMAHP groups depends on the molar ratios CHTMAC/xylan and NaOH/CHTMAC as well as on the xylan type used (Table 3).
