Dietary Supplement: Drink manufactured from lupine peptides
Registration Number
NCT02590887
Lead Sponsor
University of Seville
Brief Summary

The purpose of this study is to determine the health effects of the 4 weeks daily intake of a drink manufactured from lupine protein hydrolysates in healthy volunteers. For that, blood markers of inflammation, oxidative stress, carbohydrate, lipid, protein and liver metabolism, together with general hematology and blood coagulation will be assessed at baseline time (day 0) and after drink ingestion (day +14 and +28).

Detailed Description

The main objective of the present study is to verify the hypothesis that the intake of the drink based on lupine peptides is safe and has beneficial effects on the immune and oxidative status.

The secondary objectives are:

* Assess the effect of the drink on biological parameters of the carbohydrate, lipid, renal and hepatic metabolism as well as hematology analysis.

* Assess whether the new product is well tolerated.

* Evaluate the effect of the drink on the general health of the volunteers through the Short Form-36 health survey.

* Determine the degree of drink acceptability through the acceptability Likert test.

drink manufactured from lupine peptidesDrink manufactured from lupine peptidesBeverage drink containing 0.5mg/ml of protein hydrolysate extracted from food grade lupine flour. The drink will be formulated as 200 mL tetra brik subjected to a test of microbiological safety according to the Spanish law (RD 135/2010 of 12 February 2010). The final beverage shall consist of: * Oily phase: refined sunflower oil 5% w/w of the emulsion * Aqueous phase (water) 95% w/w of the emulsion, containing equal volumes of solution A and B: * Solution A: * Hydrolyzed Lupine (1.17% w/w) * Sucrose (14.03% w/w) * Vanilla flavor (0.42% w/w) * Drinking water (84.38% w/v) * Solution B: * Xanthan gum (0.28% w/w) * Drinking water (99.72% w/v) The samples will guard and kept by the investigator until the day of delivery to the volunteers. The duration of treatment 4 weeks, during which the volunteers daily consume the contents of a tetra brik.
