Journal ArticleDOI
Identification of the key mechanisms involved in the hydrolysis of fish protein by Alcalase
TL;DR: Inhibition by hydrolysis products resulted in a remarkable and progressive decrease in the reaction rate, which satisfactorily explained the shape of the hydrolytic curve.
Journal ArticleDOI
Recent advances and perspectives of ultrasound assisted membrane food processing
TL;DR: This review highlights the recent advances in the use of US in membrane filtration processes focused in the manufacturing of foodstuffs and food ingredients, and perspectives of novel hybrid membrane-US systems that may be quite interesting for this field.
Journal ArticleDOI
Study of effect of sodium alginate on potato starch digestibility during in vitro digestion
Cristian Ramírez,Camila Millon,Helena Nuñez,Marlene Pinto,Pedro Valencia,Cristian A. Acevedo,Ricardo Simpson,Ricardo Simpson +7 more
TL;DR: In this paper, the effects of sodium alginate mixed with a starch solution (3.0g/100g) on glucose release during in-vitro digestion were examined.
Journal ArticleDOI
Novel modeling methodology for the characterization of enzymatic hydrolysis of proteins
Pedro Valencia,Karen Espinoza,Andrés Ceballos,Marlene Pinto,Sergio Almonacid,Sergio Almonacid +5 more
TL;DR: In this paper, the authors used a combination of the logarithmic equation P = 1/bln (abt+1) with the response surface methodology to correlate the kinetic constants a and b with the operating conditions: protein concentration, enzyme concentration and temperature.
Journal ArticleDOI
Optimization of pulp density and particle size in the biooxidation of a pyritic gold concentrate by Sulfolobus metallicus
TL;DR: In this paper, the pulp density and particle size values that maximize the volumetric solubilization rate of iron from a pyritic gold concentrate were determined, and a complete experimental design of 16 runs allowed the building of response surfaces from which the optimal conditions were determined.
