Technological development and functional properties of an apple snack rich in flavonoid from mandarin juice
Abstract The development of functional foods has evolved considerably over the years. The technological ability to produce a food with enhanced physiologically active compounds has grown significantly. The aim of this work was to study the incorporation of the beneficial compounds from mandarin low pulp juice into an apple snack using vacuum impregnation technology and to test if the final product exhibited the functional properties and components of both raw materials. Forty grams of the final product made using mandarin juice homogenized at 15 MPa could provide the same quantity of hesperidin as 250 mL of fresh mandarin juice. We also performed a chromatographic determination of the compo…
Valorisation of Persimmon and Blueberry By-Products to Obtain Functional Powders: in vitro Digestion and Fermentation by Gut Microbiota
[EN] Globalization of fruit and vegetable markets generates overproduction, surpluses, and potentially valuable residues. The valorization of these byproducts constitutes a challenge, to ensure sustainability and reintroduce them into the food chain. This work focuses on blueberry and persimmon residues, rich in polyphenols and carotenoids, to obtain powders with high added value to be used as ingredients in food formulation. These powders have been characterized, and the changes in the bioactive compounds in in vitro gastrointestinal digestion have been evaluated. The results indicated that the type of residue, the drying process, as well as the content and type of fiber determine the rele…
No invasive methodology to produce a probiotic low humid apple snack with potential effect against Helicobacter pylori
Abstract A probiotic low humid apple snack with potential effect against the infection caused by Helicobacter pylori has been developed from apple (cv. Granny Smith) and mandarin juice with a high microbial content of Lactobacillus salivarius spp . salivarius , by vacuum impregnation and hot air drying techniques. The moisture content reached in the final product (0.144 ± 0.012 g water · g sample - 1 ) ensured stability, and although the drying process affected the microbial content, the concentration in the final product (9.486 ± 0.013) × 10 7 CFU g dry sample - 1 ) was sufficient to confirm that with this procedure it is possible to obtain a stable probiotic fruit with a low moisture c…
