    Notizen: Two accelerated hardening procedures (storage for up to 4 months, and soaking in acetate buffer for up to 5 h) for testing beans were examined and compared, so that new cultivars prone to the hard-to-cook (HTC) defect may be identified. Bean hardness was measured by means of the Mattson bean cooker, and by measuring puncture force. Two imporant common bean (Phaseolis vulgaris) cultivars were grown in two locations differing in soil Ca and Mg content. Those from the high Ca site had longer cooking times, which increased more rapidly on accelerated storage and in the soaking tests. The results of this preliminary study suggest that the acetate soak hardening procedure is worthy of further investigation as the basis of a rapid test for the presence of the hard-to-cook defect in new cultivars.

    Notizen: Summary A basic procedure was developed to produce a tempe-like product using the mouldRhizopus oligosporus and black common beans (Phaseolus vulgaris) as substrate. The initial pH of the substrate was 5.8, and fermentation was conducted at 37°C with a relative humidity of 70% for 72 hrs. Levels of soluble solids and soluble protein increased dramatically as a result of fermentation. Some changes were as well observed in fatty acid contents of fermented samples. It was concluded that the common bean used was an acceptable substrate for preparing this product.

    Notizen: Abstract Micro-Kjeldahl, Lowry and Bradford procedures were compared for determining the protein content ofPhaseolus vulgaris seeds during their development. Micro-Kjeldahl and biuret techniques were also compared with mature seeds of a normal and a genetically-improved bean cultivar. The protein contents of casein and soy protein isolate were as well estimated by these four methods. For many samples of both bean and food protein products large disagreements were found between micro-Kjeldahl and the other three procedures.
