“…The ash content of the three products ranged from 0.98 to 3.24%, with the LF having a significantly ( P < 0.05) lower ash content (0.98%), due to the fact that no mineral fortification was applied in the preparation of the LF (i.e., measured ash content represented innate minerals only). The macro‐chemical composition of the three plant‐based products was generally in line with previously published scientific reports for first‐age infant nutritional products, making the model LF potentially suitable for the development of next‐generation pulse‐based infant formulae 3,18,36 …”

BACKGROUND: Infant formula is a human milk substitute for consumption during the first months of life. The protein component of such products is generally of dairy origin. Alternative sources of protein, such as those of plant origin, are of interest due to dairy allergies, intolerances, and ethical and environmental considerations. Lentils have high levels of protein (20-30%) with a good amino acid profile and functional properties. In this study, a model lentil protein-based formula (LF), in powder format, was produced and compared to two commercial plant-based infant formulae (i.e., soy; SF and rice; RF) in terms of physicochemical properties and digestibility.Results: The macronutrient composition was similar between all the samples; however, RF and SF had larger volume-weighted mean particle diameters (D[4,3] of 121-134 ∼m) than LF (31.9 ∼m), which was confirmed using scanning electron and confocal laser microscopy. The larger particle sizes of the commercial powders were attributed to their agglomeration during the drying process. Regarding functional properties, the LF showed higher D[4,3] values (17.8 ∼m) after 18 h reconstitution in water, compared with the SF and RF (5.82 and 4.55 ∼m, respectively), which could be partially attributed to hydrophobic protein-protein interactions. Regarding viscosity at 95 °C and physical stability, LF was more stable than RF. The digestibility analysis showed LF to have similar values (P < 0.05) to the standard SF.Conclusion: These results demonstrated that, from the nutritional and physicochemical perspectives, lentil proteins represent a good alternative to other sources of plant proteins (e.g., soy and rice) in infant nutritional products.

“…La leche humana es un alimento óptimo y completo que se va adaptando a las necesidades nutricionales del lactante durante los primeros 4 meses de vida. La leche materna, además de un adecuado aporte de nutrientes en formas altamente biodisponibles para el lactante, supone un aporte de células vivas (linfocitos y macrófagos), enzimas digestivas, inmunomoduladores y factores de crecimiento, importantes para la correcta alimentación y desarrollo del recién nacido (17,18). No obstante, son muchos los factores que hacen que, en la actualidad, aproximadamente un 25% de madres recurren al empleo de fórmulas infantiles para la alimentación de los niños (18,19).…”

“…La adición de espesantes a las fórmulas antiregurgitación, tiene por objetivo aumentar la viscosidad para el tratamiento del reflujo gastroesofágico no complicado (18). La viscosidad se define como una medida reológica cuantitativa de la resistencia de un fluido debida al rozamiento de las partículas del mismo con la superficie por la que fluye (30) es una característica clave para el diseño y actividad de este tipo de fórmulas.…”

No obstante, los estudios sobre el efecto de la adición de estos agentes espesantes sobre la viscosidad de las fórmulas infantiles son escasos (18). Se han realizado medidas de la viscosidad in vitro, simulando para ello un proceso digestivo mediante la adición de enzimas gástricas y ácido clorhídrico.…”

“…Lo más eficaz para conseguir una viscosidad adecuada en una fórmula antiregurgitante, descartando el empleo de la adición de cereales a una fórmula comercial, sería la adición de harina de algarrobo y la presencia de niveles elevados de caseína. Es necesario establecer el límite de viscosidad máxima para este tipo de fórmulas, indicando que una viscosidad superior a 100 centipoises podría comprometer el aclaramiento esofágico y favorecer la aparición de esofagitis en el lactante (18).…”

INTRODUCCIÓNEl reflujo gastroesofágico se define como el movimiento retrógrado pasivo del alimento ingerido, desde el estómago al esófago (1-5). Los episodios de reflujo son frecuentes en los primeros meses de vida del lactante, con una incidencia del 40 -60% en los 2 -3 meses de edad, mostrando en la mayoría de las ocasiones, una tendencia natural a desaparecer hacia los 12 -18 meses de vida, despareciendo por completo en todos los niños a los 24 meses de edad (5)(6)(7)(8). No obstante, si persiste en la edad preescolar o se manifiesta en niños mayores, se observan períodos de mejoría y recaída con una tendencia a persistir hasta la edad adulta en un 50% de los casos (Armas-Ramos et al., 2010). La mayoría de los episodios de reflujo gastroesofágico son asintomáticos, ABSTRACT Gastroesophageal reflux (GER) is common in infants during the early months of life, as a result of a weak development of the regulatory mechanisms. Nevertheless, GER tends to disappear as infants grow. Nowadays, GER has become a common cause of pediatric consultation in the clinical practice, especially if it is followed by vomits. Sometimes, changing baby position while feeding seems to be a solution to reduce symptoms, while other times it is necessary manage the problem according to clinical practice guidelines. In these guidelines, the use of antiregurgitation infant formulas are included, which has been formulated with thickening agents and/or whey/casein ratio modification. Antiregurgitation milk products are available without pediatric prescription in chemists and other authorized establishments. Published studies on antiregurgitant infant formulas show some contradictory conclusions about their use. A negative effect on mineral and micronutrient bioavailability has been proposed by some authors, in relation to the presence of thickening agents used as ingredients. Different aspects which require more research, related to the use of antiregurgitation infant formulas, have been included in thisreview with the aim of producing more effective and safety products for an especially vulnerable population, where an optimum feeding will lead to an adequate development and good health status in the future.
