Postprandial glycemic and insulinemic responses to variously processed red kidney beans were evaluated in normal subjects. The dried seeds were (a) boiled; (b) autoclaved; (c) boiled, freeze-dried, and milled to obtain a precooked flour (PCF) rich in cell-enclosed starch; or (d) milled, steam-cooked, and freezedried to yield a flour containing free starch (FSF). All bean products elicited lower me
The digestibility of a mixture of starches was evaluated in balance experiments, with both normal and streptozotocin-induced diabetic rats treated with antibiotics to prevent colonic fermentation of unabsorbed material. Pancreatic amylase production in the diabetic animals was only 10% of the normal level. In spite of this, only a minor decrease in the total starch digestibility index was recorded
Measured with an enzymic method, the starch content of a raw red kidney bean (Phaseolus vulgaris) flour (RBF) was higher than that of a cooked and blended (CBB) and of a cooked, freeze-dried, and milled (CBF) preparation of the seeds. Wet homogenization as well as pepsin pretreatment of CBF increased the starch yield, indicating that starch in the cooked samples is not completely available to enzy
Dried lentils (Lens culinaris) and beans (Phaseolus vulgaris, black, brown, white, and red) were boiled until soft, freeze-dried, and milled. This procedure yielded precooked flours (PCF), rich in intact cells filled with starch granules. Starch content in the various bean PCFs was underestimated by enzymic assays. Potentially available starch in PCFs was evaluated after complete release of starch
The effect of heat treatment and dietary fiber from whole and dehulled black bean (Phaseolus vulgaris) seeds on digestibility of various starches by bovine, porcine and human pancreatic α‐amylases was studied. Corn, rice, wheat and black bean starch digestibility increased after heating. The degree of hydrolysis of black bean starch ranged between 56 and 83% of the values obtained for cereal starc
Indigestible residues from black beans (B; Phaseolus vulgaris L cv Tacarigua), green beans (G; Phaseolus vulgaris L), carrots (C; Daucus carota L) and rice bran (R; from Oryza saliva L) were prepared by the pepsin/pancreatin method of Hellendoorn et al and their effect on trypsin and pancreatic α‐amylase was evaluated comparing two experimental procedures. When the remaining caseinolytic enzyme ac
Subtilisin isoinhibitors (SI) were isolated from jack bean (Canavalia ensiformis L) and broad bean (Vicia faba L) seeds. Jack beans contain three isoinhibitors (pI 6.6, 6.3 and 6.0) that constitute 0.021 g per 100 g of dry seeds, while the two active proteins from broad beans (pI 5.7 and 5.1) represent 0.028%. The molecular weight, determined by gel filtration, is around 8000 D in both legumes. L
Insoluble and soluble dietary fiber was evaluated according to the procedure of Asp et al., in cassava bread samples from different regions of Venezuela. The values for insoluble fiber were between 4.92 and 5.67% while soluble fiber ranged between 3.40 and 3.78% (dry basis). The starch content of cassava bread samples varied between 86.5 and 88.7% (dry basis). Cassava bread starch showed an elevat
Subtilisin inhibitors (SI) having an average molecular mass of 8 kDa purified from jack beans (Canavalia ensiformis) and broad beans (Vicia faba) to electrophoretical homogeneity are compared to those isolated from chick peas (Cicer arietinum) and black beans (Phaseolus vulgaris). The specificity spectrum of SI is restricted to microbial serine proteinases. Their interaction with subtilisin Carlsb
Subtilisin inhibitors were prepared from ethanol‐acetone precipitated seed extracts of chick peas, jack beans and broad beans, heated to destroy endogenous proteases. Trypsin inhibitors were complexed with trypsin and separated from subtilisin inhibitors by molecular sieve chromatography. The eluates were again heated to avoid tryptic degradation. The procedure was easy to handle and gave satisfac
The return of individual birds to a specific area in successional years, i.e. philopatry, is a remarkable behavioural trait. Here we report on the remarkably reversed: the complete absence of returning individuals of a migratory passerine with otherwise pronounced philopatry. At a high latitude study site in Abisko (68°32ʹN, 18°80ʹE) in northern Sweden none of the banded adult willow warblers Phyl
This chapter argues for the importance of understanding recognition of prior learning (RPL) through the critical social theories of Jürgen Habermas and Axel Honneth. Results from a research project exploring RPL for the accreditation of prior experiential learning in the healthcare sector in Sweden are used to develop the analysis. It is argued that RPL for accreditation could, by reflecting the r
Intracardiac hemodynamic forces have been proposed to influence remodeling and be a marker of ventricular dysfunction. We aimed to quantify the hemodynamic forces in repaired tetralogy of Fallot (rToF) patients to further understand the pathophysiological mechanisms as this could be a potential marker for pulmonary valve replacement (PVR) in these patients. Patients with rToF and PR>20% (n=18) and
