The inclusion of dry beans in diets has clear health benefits. However, consumers in developed countries mainly choose beans for their sensory qualities, especially for their texture. This article describes the constitution, training and validation of a panel of judges to evaluate the texture of dry beans. The judges were trained in the perception of different textures, analyzed a wide range of beans and selected seed-coat roughness, seed-coat perceptibility and creaminess/mealiness of the cotyledon as the main attributes to be scored. After training, the panel was capable of discriminating between different varieties of beans and even between beans of the same variety grown at different locations. The analysis of the behavior of the panel in a standard tasting session 2 years after its formation showed that periodic inclusion of samples from the extremes of the scales for the attributes during tasting sessions was sufficient to keep the panel trained.
This article could serve as a guide for the training of sensory panels to evaluate the texture of dry beans. It describes the selection of the attributes on which the analysis is based, references for the extreme values of the attributes and how to train the panel. It also provides a practical example of the analysis of the behavior of the panel some time after training. 相似文献

The upper and lower limits of the excitation function of the 63Cu(n,p)63Ni reaction were experimentally determined, and the number of 63Ni nuclei produced in copper samples exposed to atomic bomb neutrons in Hiroshima was estimated by using the experimental
excitation functions and the neutron fluences given in the DS02 dosimetry system. The estimated number of 63Ni nuclei was compared with that measured and with that calculated using the DS02 dosimetry system and the corresponding ENDF/B-VI
cross section. In comparison with DS02, there is about a 60% maximum difference in 63Ni production at the hypocenter when the experimental upper cross section values are used. The difference becomes smaller
at greater distances from the hypocenter and decreases, for example, to less than 30 and 5% when using the upper and lower
experimental cross sections at 1,000 m, respectively. 相似文献

Using N2 cavitation, we established a protocol to prepare the active mitochondria from Plasmodium falciparum showing a higher succinate dehydrogenase activity than previously reported and a dihydroorotate-dependent respiration. The fact that fumarate partially inhibited the dihydroorotate dependent respiration suggests that complex II (succinate–ubiquinone reductase/quinol–fumarate reductase) in the erythrocytic stage cells of P. falciparum functions as a quinol–fumarate reductase. 相似文献

Characterization of picomolar affinity binding sites for [125I]-human calcitonin gene-related peptide in rat brain and heart 总被引:1,自引:0,他引:1

We have characterized picomolar affinity binding sites for human calcitonin gene-related peptide (CGRP) in rat brain and heart (atria and ventricle) membranes. By saturation analysis, apparent dissociation constant (KD) values of high affinity sites for [125I]-human CGRP are 9 approximately 15 pM (brain), 34 pM (ventricle) and 85 pM (atria). Low affinity sites with KD values of about 50 nM are found in rat brain and ventricle, but not in atria. Human and rat CGRP potently inhibited [125I]-human CGRP binding to these high affinity sites with apparent inhibition constant (Ki) values comparable to their KD values. Salmon calcitonin marginally inhibited these binding with Ki values between 0.1 microM and 1 microM. Extremely potent cardiovascular and gastrointestinal actions of CGRP might be mediated through CGRP binding sites with picomolar affinity which are similar to those we characterized in this study. 相似文献

A protocol has been worked out for separating all thirteen different polypeptides in the beef heart cytochrome c oxidase complex from a single aliquot of enzyme. This involves an initial separation of polypeptides by gel filtration on a Biogel P-60 column in SDS, a step which purifies subunits CIV and CVIII and gives mixtures of CV + CVI, ASA, AED and STA, as well as CVII, CIX and IHQ. These mixtures are then resolved by reverse-phase high-performance liquid chromatography. The separation procedures have been applied to fetal heart cytochrome c oxidase of gestation between 100 and 200 days. No differences were found in the N-terminal sequences of any of the cytoplasmically made subunits or in the entire sequence of CIX between late fetal and adult forms of the enzyme. 相似文献

The mechanism of the stimulatory effect of a cytokinin, namely,benzyladenine (BA), on the synthesis of 5-aminolevulinic acid(ALA) in cucumber cotyledons was studied. The rate of synthesisof ALA by plastids isolated from BA-treated cotyledons was twicethat by plastids from untreated controls. Western blot analysisof stromal proteins showed that BA did not affect the levelof glutamyl-tRNA synthetase or of glutamate l-semialdehyde (GSA)aminotransferase. Analysis of free amino acids revealed thatBA did not increase the level of glutamate in the stroma. However,the amount of total plastidic RNA was doubled in BA-treatedcotyledons. Northern blot analysis showed that the level ofplastid tRNAGlu was increased by treatment with BA to the sameextent as that of another plastid tRNA, reflecting an increasein total plastidic RNA. The rate of formation of glutamyl-tRNAwas also doubled in plastids from BA-treated cotyledons. Theresults indicate that stimulation of the synthesis of ALA byBA is due to an increased level of tRNAGlu in plastids. (Received June 6, 1993; Accepted November 26, 1993) 相似文献
