Comparison of endolytic hydrolases that depolymerise 1,4-β-D-mannan, 1,5-α-L-arabinan and 1,4-β-D-galactan.

McCleary, B. V. (1991). “Enzymes in Biomass Conversion”, (M. E. Himmel and G. F. Leatham, Eds.), ACS Symposium Series, 460, Chapter 34, pp. 437-449. American Chemical Society, Washington.

Hydrolysis of mannan-type polysaccharides by β-mannanase is dependent on substitution on and within the main-chain as well as the source of the β-mannanase employed. Characterisation of reaction products can be used to define the sub-site binding requirements of the enzymes as well as the fine-structures of the polysaccharides. Action of endo-arabinanase and endo-galactanase on arabinans and arabinogalactans is described. Specific assays for endo-arabinanase and arabinan (in fruit-juice concentrates) are reported.

Novel and selective substrates for the assay of endo-arabinanase.

McCleary, B. V. (1989). "Gums and Stabilisers for the Food Industry, Vol 5”, (G. O. Phillips, D. J. Wedlock and P. A.Williams, Eds.), IRL Press, pp. 291-298.

Substrates and assay procedures for the measurement of endo-1,5-α-L-arabinanase in crude, technical pectinase preparations have been developed. The method of choice employs carboxymethy1-debranched beet araban as substrateT and rate of hydrolysis is measured using the Nelson-Somogyi reducing-sugar procedure with arabinose as the standard. The substrate is physically and chemically stable in solution, and the assay procedure is simple, reliable and specific. Other assay procedures for the measurement of endo-arabinanase which employ dyed debranched araban substrates, are also briefly described.

Partial replacement of β-casein by napin, a rapeseed protein, as ingredient for processed foods: Thermoreversible aggregation.

Schwartz, J. M., Solé, V., Guéguen, J., Ropers, M. H., Riaublanc, A. & Anton, M. (2015). LWT-Food Science and Technology, 63(1), 562-568.

Environmental, demographic and economic motives draw a worldwide tendency to introduce plant proteins into processed foods. However the total replacement of animal proteins by plant proteins is not easy to perform due to the specific physicochemical properties (aggregation, solubility, interactions …) and taste of these proteins. In a first step, combined plant/animal assemblies could be an attractive approach. Consequently, to drive this trend towards practical applications, deeper investigations must be performed to control the properties of such mixed assemblies. In the current study, the interactions of β-casein with napin, a rapeseed protein poorly valorized in human nutrition, was investigated in various physico-chemical conditions (pH, sodium chloride concentration, mass ratio). The properties of the mix were followed by turbidimetry, and microscopy. The statistical analysis of the whole set of data indicated that the effects of the three factors were significant (p < 0.05) without significant cross effects. Furthermore, the aggregation is enhanced by temperature with a reversible effect. The aggregation is also suppressed by adding salt or divalent cation chelating agents (ethylene diamine tetracetic acid, EDTA). The functional combination of β-casein with napin can thus be controlled by modulating the salinity of the media and/or by introducing a complexing agent.
