Physicochemical and structural characterization of whey protein concentrate-tomato pectin conjugates.

Background: Protein-pectin conjugates, obtained through a controlled Maillard reaction in blends of precursors, are studied for their contribution to improving the emulsifying and thermal properties of proteins. The objective was to obtain a conjugate between whey protein concentrate (WPC) and non-conventional pectins extracted in acid (acid tomato pectin, ATP) and aqueous medium (water tomato pectin, WTP) from industrialized tomato residues (tomato waste, TW), characterize the conjugates and study their emulsion properties. The Maillard reaction was carried out at 60 °C and 75% relative humidity in blends with 2:1 proportions; 1:1 and 1:2 (m :m ) for 3, 6 and 12 days.

Sodium Content in Commonly Consumed Foods and Its Contribution to the Daily Intake.

Salt consumption in many countries of the world exceeds the level recommended by WHO (5 g/day), which is associated with negative effects on health. Public health strategies to achieve the WHO's objectives include salt content monitoring, improved nutritional labelling and product reformulation. This study aimed to determine the sodium content in street food (SF), fast foods (FF) and artisanal foods (AF) of the Northwest of Argentina, which is not regulated.

Formulation and attributes of gluten-free cakes of Andean corn improved with green banana flour.

The aim of this work was obtaining layer and sponge cakes formulated with corn flour replaced by green banana flour and to determine the best substitution proportions to achieve nutritionally improved products and with texture and sensory characteristics acceptable. The replacement of corn flour by GB flour increased the density in layer cake batters, while in sponge cake batters the density decreased. The batters were influenced by the increase in the flow properties, the viscoelastic behaviour, and the decrease in the thixotropic properties.

Biodiversity of Andean potatoes: Morphological, nutritional and functional characterization.

Andean potatoes (Solanum tuberosum andigenum) are a staple food for Andean population; there is great biodiversity but only few varieties are cultivated nowadays. In order to contribute to biodiversity conservation of Andean potatoes, information about their morphological, nutritional and functional characteristics was generated. In gene bank (INTA-Balcarce), varieties collected from regional producers were preserved.

Acceptability of beehive products as ingredients in quinoa bars.

Background: The aim of this work was to develop a puffed quinoa bar with beehive products of high content of phenolic compounds, based on acceptability and perception of consumers. A rotational central composite design of three variables (honey, pollen and propolis) was used for food product formulation. The responses to optimize were sensorial acceptability and polyphenol content.

Protein content and amino acids profile of pseudocereals.

Quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and buckwheat (Fagopyrum esculentum) represent the main protein source in several diets, although these pseudocereals are not currently present in the FCDB nutrient profile information. The aim of this work is to characterise the AA profile of these pseudocereals and compare them with rice. Total protein content revealed to vary from 16.

Health properties of oca (Oxalis tuberosa) and yacon (Smallanthus sonchifolius).

Andean roots and tubers are underexploited crops; many contain compounds beneficial to health, so a greater knowledge of their properties is important for encouraging their consumption. The aim of this work was to study the content of bioactive compounds of yacon and oca and their effect on intestinal health using as a model rats of the Wistar strain. Two varieties of ocas (Overa and Rosada) and yacon, which contain significant amounts of fructooligosaccharides and phenolic compounds, were chosen.

Functional bread with n-3 alpha linolenic acid from whole chia (Salvia hispanica L.) flour.

This work proposed to study the effects of the addition of whole chia flour (WCF) on the technological, nutritional and sensory qualities of bread. Different WCF contents (0 and 20 %) and vital gluten (VG) (0 and 4 %) were added to bread according to a 2(2) central composite rotational design. WCF decreased the specific volume, lightness and hue angle of the bread loaves, but did not affect the chroma values.
