Sesame oil produced by the traditional aqueous extraction process (TAEP) has been recognized by its pleasant flavor and high nutrition value. This paper developed a rapid and nondestructive method to predict the sesame oil yield by TAEP using near-infrared (NIR) spectroscopy. A collection of 145 sesame seed samples was measured by NIR spectroscopy and the relationship between the TAEP oil yield and the spectra was modeled by least-squares support vector machine (LS-SVM). Smoothing, taking second derivatives (D2), and standard normal variate (SNV) transformation were performed to remove the unwanted variations in the raw spectra. The results indicated that D2-LS-SVM (4000–9000 cm−1) obtained the most accurate calibration model with root mean square error of prediction (RMSEP) of 1.15 (%, w/w). Moreover, the RMSEP was not significantly influenced by different initial values of LS-SVM parameters. The calibration model could be helpful to search for sesame seeds with higher TAEP oil yields.

Chickpea husks were extracted by non-alkaline aqueous extraction process and then ground in flour mill. The unextracted husks were also ground in flour mill. The analysis of chickpea husk showed that extracted husk was lower in moisture, protein, ash and fat but higher in carbohydrate and crude fiber contents compared to unextracted husk. Chapattis were prepared incorporating different levels of extracted and unextracted chickpea husk and evaluated for various quality parameters as weight, width, thickness, spread ratio, and moisture content. The chapatti containing extracted husk had higher moisture, carbohydrate and crude fiber content but lower in protein and ash content than that of chapatti containing unextracted husk. Chapattis were also prepared incorporating various levels of salt, baking powder and water. The quality of chapattis was evaluated. Chapatti prepared from 5% extracted husk required 2.0% salt, 1.5% baking powder and 62% water for producing reasonably acceptable quality while chapatti from 5% unextracted husk required 1.5% salt, 1.5% baking powder and 60% water for achieving better quality. Chapattis were prepared with 5% extracted husk required higher salt and water than that of 5% unextracted husk. Chapattis were evaluated organoleptically by a taste testing panel. The overall acceptability of chapattis without husk was followed by chapattis incorporated with 5% extracted husk.
