Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Functional Bread From Bambara Groundnut and Orange Peel Attenuates Hyperglycemia and Oxidative Stress in a High‐Fat Diet/Streptozotocin‐Induced Type 2 Diabetes Rat Model

Food Chemistry International, EarlyView.
This study evaluated Bambara groundnut–wheat composite bread fortified with orange peel in diabetic rats. Diets significantly lowered blood glucose, inhibited α‐glucosidase and α‐amylase, and boosted antioxidant enzymes compared to controls. Results emphasize BG‐based functional foods' potential to help manage type 2 diabetes through regulation of ...

Queer configurations: The female divine, regional identity, and Queer‐religious belonging in South India

Feminist Anthropology, EarlyView.
Abstract This article explores how queerness and religion intersect in a unique enactment of Bathukamma, a flower festival honoring the female divine in Hyderabad, the capital of the South Indian state of Telangana. Drawing on theories of figuration, I analyze how local queer organizations celebrate the festival in a way that engages two distinctive ...

Impact of tomato variety and homogenization pressure on in vitro lipid digestion and lycopene bioaccessibility in tomato emulsions

Food Biomacromolecules, EarlyView.
Tomato variety and processing impact lycopene bioaccessibility. Tomato emulsions with high pectin content decreased the in vitro lipid digestion and negatively affected lycopene bioaccessibility. High pressure homogenization may enhance the release of lycopene into emulsion oil droplets, but it may also reduce the transfer of lycopene into the micellar
