Emission spectroscopy of the nonthermal multi-needle corona discharge revealed prominent OH (A-X) and N<sub>2</sub> (C<img>B) emissions with a gas temperature of 330 ± 5 K and electron density of (2.6 ± 0.1) × 10<sup>21</sup> m<sup>−3</sup>.

This study assessed the effects of fermentation time and heat treatment for development of tempeh classified as IDDSI level 6.

Before cooking, tempeh exhibited increased hardness and brittleness by cake, as well as pH, total soluble solids, and DPPH increased by enzymetic activity. Fungal enzymes and heat treatment (175 °C) changed the rough and aggregated microstructure and molecular structure of chickpeas, as confirmed by scanning electron microscopy and Fourier transform infrared spectroscopy. The texture of cooked tempeh became softer and less brittle by fermentation time, attributed to weakening of cake bonds and enzymatic softening of chickpeas.
