Production of aroma compounds from whey using Wickerhamomyces pijperi

Production of Food Aroma Compounds: Microbial and Enzymatic Methodologies

Over the past few years, the increasing demand for natural products in the food industry has encouraged remarkable efforts towards the development of biotechnological processes for the production of flavour compounds. The present paper reviews the recent major achievements reported in this field, with a special emphasis on the potential lying in plant cell, microbial cultures and enzyme technol...

Production and purification of lactase of Kluyveromyces fragilis from whey

Characteristic aroma compounds from different pineapple parts.

Characteristic aroma volatile compounds from different parts of cayenne pineapple were analyzed by headspace-solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC/MS). The main volatile compounds were esters, terpenes, ketones and aldehydes. The number and content of aroma compounds detected in pulp were higher than those found in core. In pulp, the characteristic a...

Production of L(+) Lactic Acid using Lactobacillus casei from Whey

The aim of this work was to study the fermentation of whey for the production of L(+) lactic acid using Lactobacillus casei. The effect of different process parameters such as pH of the medium, temperature, inoculum size, age of inoculum, agitation and incubation time was monitored to enhance the lactose conversion in whey to L(+) lactic acid. Fermentations were performed without any pH control...

The Use of Enzymes and Microorganisms for the Production of Aroma Compounds from Lipids

Lipids are an important source of aroma compounds. In foods, lipids are degraded or modified by enzymatic activities that are originally present in the raw materials or that develop later due to the growth of microorganisms. Mimicking these natural pathways, some processes have been developed to produce aroma compounds in bioreactors. In this review we describe the production of aroma compounds...
