Seed protein pattern of control and M
mutant soybean (
[L.] Merr.) lines in defatted and non-defatted raw flour was studied after 60% 2-propanol extraction, SDS-PAGE separation, colloidal staining and densitometric evaluation to detect a new variant of the protein KTI and/or BBI, furthermore to find new protein(s) of low molecular weight. Electrophoretic separation of defatted and non-defatted control soybean samples showed the same protein patterns. On the densitograms of mutant lines quantitative and qualitative differences could be observed. Defatted raw soy samples reflected more differences in the number of peaks than non-defatted ones. Beside soy trypsin inhibitors, several more soy proteins of low molecular weight are dissolved. KA mutant line 9 has a unique 2-propanol soluble protein pattern, and a new protein band of Rf=0.37 compared to the control line. Sixty percent 2-propanol soluble soybean seed proteins are suitable for cultivar identification and characterization, furthermore to distinguish soybean lines of the same origin.
Lycopene content (LC) and soluble solid content (SSC) are important quality indicators for cherry tomatoes. This study attempted simultaneous analysis of inner quality of cherry tomato by Electronic nose (E-nose) using multivariate analysis. E-nose was used for data acquisition, the response signals were regressed by multiple linear regression (MLR) and partial least square regression (PLS) to build predictive models. The performances of the predictive models were tested according to root mean square and correlation coefficient (R2) in the training set and prediction set. The results showed that MLR models were superior to PLS model, with higher value of R2 and lower values of for RMSE firmness, pH, SSC, and LC. Together with MLR, E-nose could be used to obtain firmness, pH, soluble solid and lycopene contents in cherry tomatoes.
