Obtaining fermentable sugars and fiber concentrate from asparagus by‐product

Abstract

In this study, different solid-liquid extraction conditions to obtain fermentable sugars from an asparagus by-product were investigated to produce a fiber concentrate.To evaluate the effects of agitation, solvent:sample ratio and temperature, an experimental design was used and the maximum extraction conditions of reducing sugars (RS) were determined. The diffusion coefficient of sugars in water at different temperatures was obtained, as well as the thermodynamic parameters of the process. The materials obtained before and after the extraction were characterized as composition, technological properties, and functional groups. The results showed that, under the conditions evaluated, agitation had the highest influence on the RS extraction, followed by the solvent:sample ratio and temperature. The maximum RS content (~30 g 100 g −1 dry asparagus by-product) was obtained at 125 rpm, 60°C,

Pretreatment effect of osmotic dehydration on ultrasound‐assisted solvent extraction: Functional properties of defatted hazelnut meal

“…Methods that can be used to purify the protein meal include alcohol precipitation, isoelectric precipitation, and alkaline solution with isoelectric precipitation. Previous researchers have reported that the functional properties of agricultural products could be affected by various treatment methods (De Paula Laidens et al, 2021;Iwassa et al, 2019;Wu et al, 2009).…”

The aroma analysis of asparagus tea processed from different parts of green asparagus ( Asparagus officinalis L.)

“…Asparagus ( Asparagus officinalis L.), as a perennial herb, is widely grown in many countries of its high value of rich in protein, vitamins and mineral elements (Laidens et al., 2021; Romojaro et al., 2013). As a health care vegetable, there were about ninety‐four compounds identified from asparagus (Jiménez‐Sánchez et al., 2016).…”
