## Abstract Seed hulls from both sweet and bitter varieties of lupins (__Lupinus angustifolius__) have been analysed for constituent polysaccharides. The hulls contained 15 to 32% oxalateβsoluble pectic polysaccharide, excluding pentose, 12 to 14% hemiβcellulose, 44 to 51% cellulose, 0.3 to 0.4% li
## Abstract The proportion of seed coats (hulls) of four varieties of sweet lupin seeds ranged from 19 to 25%. The amount of hull varied inversely with the weight of the seed, within each variety. __Lupinus luteus__ cv Weiko III had 40.1% protein (dry basis); of 3 cultivars of __L. angustifolius__
## Abstract The bitterness of a saponin mixture (containing saponin B and DDMP (2,3βdihydroβ2,5βdihydroxyβ6βmethylβ4__H__βpyranβ4βone) saponin in a ratio of 1:4) and saponin B obtained from dry peas were established by a trained panel using line scaling. Both saponins were found to be bitter. Howev
## Abstract The chemical composition and protein quality of the kernels from __Lupinus angustifolius__ seeds were compared with that for sprouts after 6 days germination. Germination resulted in an apparent increase in protein content from 395 g kg^β1^ to 435 g kg^β1^ DM. Fat and carbohydrate conte
