“…The values of %DP for experimental EF (73.98-99.90 %) were higher than those reported for de Oliveira and Canniatti-Brazaca [32] from experimental EF. Using the selected experimental design, we found that %DP was adversely affected by SP content; the lowest values were found in formulas with the highest SP content.…”

Enteral formulas (EF) are complex food systems which have all the nutrients in their matrix for the complete human nourishment. However, there are components in EF which can interact with minerals, reducing their absorption, and thereof the EF nutritional quality. The effect of soy protein (SP) and Ca content on Fe, Zn, and Ca bioaccessibility and protein digestibility (%DP) was assessed using a response surface design in EF. Tested SP levels were 2.5-5.0 g/100 mL of total protein. Ca levels were adjusted with Ca citrate within a range between 50 and 100 mg/100 mL. SP content negatively influenced %DP and Fe, Zn and Ca bioaccessibility. As SP content increased, mineral bioaccessibility and %DP decreased, probably due to the increased levels of phytic acid and trypsin inhibitors from SP. Ca content only affected %DCa, which had a direct relationship with Ca levels, while did not affect Fe and Zn bioaccessibility or %DP. Since Ca citrate did not impair Fe and Zn bioaccessibility, it could be an appropriate Ca source for EF fortification.

Pereskia aculeata: biological analysis on wistar rats

et al. 2017

Pereskia aculeata Mill., a species of the family Cactaceous, popularly known in Brazil as ora-pro-nobis, has high protein, vitamin and mineral contents. High essential amino acid concentrations should be underscored, suggesting a better evaluation of the fractions. Current study quantifies amino acid content and the chemical score (CS) of protein amino acids, determining in vivo digestibility, protein efficiency ratio (PER) and net protein ratio (NPR) of P. aculeata. Plant material was collected, washed, placed in an oven at 60 °C, ground and stored in a freezer for chemical analysis. Diets that maintain isoproteic and isocaloric characteristics were prepared for the bioassay, namely: casein (no protein) and Pereskia aculeata leaves-based flour. Eighteen male albino Wistar rats, divided into three experimental groups of 6 animals each, were used to evaluate protein quality and bioavailability of micronutrients. Pereskia aculeata flour provided as a single source is inadequate for growth, although it is relevant for maintaining protein metabolism indicated by net protein ratio (2.87). It is actually a good quality protein source due to few limiting essential amino acids, and it meets the diet requirements for humans.Keywords: Ora-pro-nobis; protein quality; digestibility; PER; NPR; PDCAAS.Practical Application: Pereskia aculeata when provided as a single source is not adequate for proper growth, however it is important the adequacy of maintaining the protein metabolism indicated by net protein ratio. During the experiment, animals fed on Pereskia aculeata gained less weight when compared with animals fed on casein, mean weekly feed consumption was also low. And it is a good protein source good quality due to present few limiting essential amino acids and thus are able to meet the needs for the diet in humans.
