Hydrolized sweet almond protein
La proteina idrolizzata di mandorla dolce è ricavata dai semi della mandorla dolce (Prunus amygdalus), una pianta ampiamente conosciuta e apprezzata. La proteina viene estratta tramite un processo di idrolisi, in cui le proteine presenti nelle mandorle vengono scomposte in peptidi più piccoli, che sono più facili da assorbire dalla pelle e dai capelli. Questo estratto viene utilizzato nei cosmetici e nei prodotti per la cura della persona per i suoi benefici nutritivi, idratanti e condizionanti. È particolarmente efficace nel migliorare l'idratazione, la morbidezza e la salute complessiva della pelle e dei capelli.
La proteina idrolizzata di mandorla dolce contiene diversi componenti chiave, tra cui:
Applicazioni Mediche
Cosmetici
Balsamo per la pelle e per i capelli, agente protettivo per capelli, film-former. Discreta capacità antistatica.

La mandorla (Prunus dulcis) ha origini asiatiche, appartiene alla famiglia delle Rosaceae.
E' energetica: in 100 grammi troviamo circa 600 kcalorie.
Ha molte varietà, ma le più conosciute sono
La mandorla dolce è ricca di grassi monoinsaturi, fibre, magnesio, può regolare l'omeostasi del glucosio, è ipocolesterolemica (1), svolge un'azione antiossidante (2) ed è un coadiuvante per i rischi cardiovascolari.(3).
Ha una buona quantità di grassi monoinsaturi, fibre, magnesio, può regolare l'omeostasi del glucosio, è ipocolesterolemica cioè può ridurre il colesterolo dannoso, svolge un'azione antiossidante ed è un coadiuvante per i rischi cardiovascolari.
Attenzione: la mandorla amara è tossica.
Questo studio ha trovato un'associazione statisticamente significativa tra l'alta frequenza di consumo di arachidi, pinoli, mandorle e la riduzione del rischio di cancro colorettale (4).
Dalla mandorla dolce si ricava :
Per quanto riguarda il sottoprodotto industriale della mandorla piuttosto diffuso, il latte di mandorla, specialmente nelle versioni zuccherate, occorre fare attenzione perché hanno un potenziale cariogenico (5).
Mentre la mandorla dolce ha molte proprietà benefiche per la salute umana, la mandorla amara è tossica anche a dosi relativamente piccole in quanto ne sono sufficienti 5 o 6 per provocare intossicazioni. Può essere mortale a dosi superiori. Il sapore amaro, collegato ad un componente, l'amigdalina, fortunatamente, provvede a scoraggiare dall'ingestione.
Dalla mandorla amara si ricava, previa depurazione dell'acido cianidrico ivi contenuto :

de Souza TSP, Dias FFG, Oliveira JPS, de Moura Bell JMLN, Koblitz MGB. Biological properties of almond proteins produced by aqueous and enzyme-assisted aqueous extraction processes from almond cake. Sci Rep. 2020 Jul 2;10(1):10873. doi: 10.1038/s41598-020-67682-3.
Abstract. The almond cake is a protein-rich residue generated by the mechanical expression of the almond oil. The effects of the aqueous (AEP) and enzyme-assisted aqueous extraction processes (EAEP) on the biological properties of the almond cake protein were evaluated. Total phenolic content (TPC), antioxidant capacity, inhibitory effects against crucial enzymes related to metabolic syndrome, antimicrobial potential, and in vitro protein digestibility profile were assessed. EAEP provided the best results for antioxidant capacity by both ORAC (397.2 µmol TE per g) and ABTS (650.5 µmol TE per g) methods and also showed a high (~ 98%) potential for α-glucosidase inhibition. The AEP resulted in protein extracts with the highest lipase inhibition (~ 70%) in a dose-dependent way. Enzymatic kinetic analyses revealed that EAEP generated uncompetitive inhibitors against α-glucosidase, while EAEP, AEP, and HEX-AEP (used as control) generated the same kind of inhibitors against lipase. No protein extract was effective against any of the bacteria strains tested at antimicrobial assays. An in silico theoretical hydrolysis of amandin subunits corroborated with the results found for antioxidant capacity, enzyme inhibitory experiments, and antimicrobial activity. Digestibility results indicated that the digestive proteases used were efficient in hydrolyzing almond proteins, regardless of the extraction applied and that HEX-AEP presented the highest digestibility (85%). In summary, EAEP and AEP skim proteins have the potential to be used as a nutraceutical ingredient. The biological properties observed in these extracts could help mitigate the development of metabolic syndrome where EAEP and AEP skim proteins could be potentially used as a prophylactic therapy for diabetes and obesity, respectively.

Abstract. In this study, the production, fractionation, purification and identification of ACE (angiotensin-I-converting enzyme) inhibitory peptides from wild almond (Amygdalus scoparia) proteins were investigated. Wild almond proteins were hydrolyzed using 5 different enzymes (pepsin, trypsin, chymotrypsin, alcalase and flavourzyme) and assayed for their ACE inhibitory activities. The degree of ACE inhibiting activity obtained after hydrolysis was found to be in the following order: alcalase > chymotrypsin > trypsin/pepsin > flavourzyme. The hydrolysates obtained from alcalase (IC50 = 0.8 mg/mL) were fractionated by sequential ultrafiltration at 10 and 3 kDa cutoff values and the most active fraction (<3 kDa) was further separated using reversed phase high-performance liquid chromatography (RP-HPLC). Peptide sequence identifications were carried out on highly potential fractions obtained from RP-HPLC by means of liquid chromatography coupled to electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). Sequencing of ACE inhibitory peptides present in the fraction 26 of RP-HPLC resulted in the identification of 3 peptide sequences (VVNE, VVTR, and VVGVD) not reported previously in the literature. Sequence identification of fractions 40 and 42 from RP-HPLC, which showed the highest ACE inhibitory activities (84.1% and 86.9%, respectively), resulted in the identification of more than 40 potential ACE inhibitory sequences. The results indicate that wild almond protein is a rich source of potential antihypertensive peptides and can be suggested for applications in functional foods and drinks with respect to hindrance and mitigation of hypertension after in vivo assessment. Practical application: This study has shown the potential of wild almond proteins as good sources for producing ACE-inhibitory active peptides. According to this finding, peptides with higher ACE inhibitory activities could be released during the gastrointestinal digestion and contribute to the health- promoting activities of this natural protein source. © 2017 Institute of Food Technologists®.

Abstract. This study aimed to discover and prepare novel angiotensin converting enzyme (ACE) inhibitory peptides from almond protein and further evaluate the effect on endothelial function of human umbilical vascular endothelial cells (HUVECs). Almond protein was hydrolyzed using a two-stage alcalase-protamex hydrolysis process, and the hydrolysates were subjected to a series of separations, ultrafiltration, gel filtration chromatography, and reversed-phased preparative chromatography, to obtain the active peptides. Seven ACE inhibitory fractions with the molecular weight below 1.5 kDa were isolated and prepared, and two purified ACE inhibitory peptides with the IC50 values of 67.52 ± 0.05 and 43.18 ± 0.07 μg mL(-1), were identified as Met-His-Thr-Asp-Asp and Gln-His-Thr-Asp-Asp, respectively. Then the effect of two ACE inhibitory peptides on the endothelial function of HUVECs was evaluated. Results showed that the two potent ACE inhibitory peptides significantly regulated the release of nitric oxide and endothelin in HUVECs. These results suggest that almond peptides have potential as an antihypertensive nutraceuticals or a functional food ingredient.
