Biscotti fatti in casa con avena e farina integrale, dolcificati con stevia ed eritritolo

https://www.my-personaltrainer.it/Tv/Ricette/Dolci_Dessert/biscotti-integrali-senza-zuccheri-aggiunti.html

Ingredienti Ricetta

Ingredienti per 20 biscotti

100 g di farina integrale
50 g di fiocchi d’avena
40 g di preparato a base di stevia ed eritritolo o un altro tipo di dolcificante
20 ml di olio di semi di mais
50 g + 10 g di nocciole
50 g di datteri
4 g di lievito per dolci
50 ml di acqua
1 pizzico di sale

Preparazione Biscotti Integrali Vegani Senza Zucchero Aggiunto

1. In un frullatore, riunire 50 g di nocciole ed i fiocchi d’avena: tritare fino ad ottenere una polvere impalpabile.

2. Denocciolare i datteri, tagliarli a pezzi e riunirli nel bicchiere di un frullatore. Tritare i datteri fino a formare una crema.

3. In una ciotola, riunire la polvere di nocciole ed avena, la farina integrale, il lievito setacciato, il sale ed il dolcificante a base di stevia ed eritritolo.

Dolcificante stevia ed eritritolo: di che si tratta?

La stevia (Stevia rebudiana) è una pianta perenne da sempre apprezzata per le sue straordinarie capacità dolcificanti. Non a caso, la stevia è battezzata anche con il nome di “erba dolce o erba del miele”: infatti, le sue foglie sono ricchissime di componenti glucosidici (es. stevioside) dal potere edulcorante che arriva talvolta a superare di 300 volte la dolcezza del saccarosio. Possiede anche proprietà ipoglicemizzanti e si può definire una sostanza acariogena.
L’eritritolo è un dolcificante innovativo appartenente alla categoria dei polioli. È una sostanza naturalmente presente nella frutta e nei cibi fermentati (ma viene prodotto anche industrialmente per fermentazione batterica degli zuccheri) e possiede un indice glicemico pari a zero. Inoltre, questo particolare dolcificante apporta solo 0.2 Kcal/g ed ha un potere dolcificante di circa il 70% rispetto allo zucchero classico.
Entrambe le sostanze dolcificanti sono stabili al calore e non caramellano in cottura!
1 g di questa polvere dolcificante è in grado di apportare la stessa dolcezza fornita da 2 g di saccarosio, con un risparmio calorico del 100%!

4. Con le mani, amalgamare le polveri con la crema di datteri: si dovrà ottenere un composto di briciole.

5. A questo punto, mischiare il tutto con olio di semi ed acqua: amalgamare con le mani ed ottenere una pasta morbida e non appiccicosa.

6. Avvolgere la pasta in un foglio di pellicola trasparente e lasciar riposare per mezz’ora.

7. Con il matterello, stendere la pasta di biscotti sulla spianatoia, aiutandosi eventualmente con un po’ di farina integrale. Ottenere uno sfoglio di pasta dallo spessore di circa mezzo centimetro.

8. Con un taglia-biscotti dalla forma a piacere ottenere i biscotti e disporli man mano su una piastra foderata con carta da forno. I ritagli si possono rimpastare per ricavare altri biscotti.

9. Tagliare a metà le nocciole rimanenti.

10. Inserire metà nocciola al centro di ogni biscotto.

11. Infornare i biscotti e cuocere a forno caldo, preriscaldato a 180°C, per 12 minuti (per ottenere biscotti morbidi) o per 15 minuti (per ottenere biscotti più croccanti).

12. Sfornare i biscotti, lasciar intiepidire e servire.

13. I biscotti vegani senza zuccheri aggiunti si possono conservare in una scatola di latta per 7-10 giorni.

https://en.wikipedia.org/wiki/Polymer

A polymer is a large molecule (macromolecule) composed of repeating structural units. These sub-units are typically connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of compounds comprising both natural and synthetic materials with a wide variety of properties.

Because of the extraordinary range of properties of polymeric materials, they play an essential and ubiquitous role in everyday life. This role ranges from familiar synthetic plastics and elastomers to natural biopolymers such as nucleic acids and proteins that are essential for life.

Natural polymeric materials such as shellac, amber, wool, silk and natural rubber have been used for centuries. A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper. The list of synthetic polymers includes synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, polyacrylonitrile, PVB, silicone, and many more.

Most commonly, the continuously linked backbone of a polymer used for the preparation of plastics consists mainly of carbon atoms. A simple example is polyethylene (‘polythene’ in British English), whose repeating unit is based on ethylene monomer. However, other structures do exist; for example, elements such as silicon form familiar materials such as silicones, examples being Silly Putty and waterproof plumbing sealant. Oxygen is also commonly present in polymer backbones, such as those of polyethylene glycol, polysaccharides (in glycosidic bonds), and DNA (in phosphodiester bonds).

Polymers are studied in the fields of polymer chemistry, polymer physics, and polymer science…

Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some chemical groups may be lost from each monomer. This is the case, for example, in the polymerization of PET polyester. The monomers are terephthalic acid (HOOC-C6H4-COOH) and ethylene glycol (HO-CH2-CH2-OH) but the repeating unit is -OC-C6H4-COO-CH2-CH2-O-, which corresponds to the combination of the two monomers with the loss of two water molecules. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue…

https://en.wikipedia.org/wiki/Synthetic_rubber

Synthetic rubber is any type of artificial elastomer, invariably a polymer. An elastomer is a material with the mechanical (or material) property that it can undergo much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation.About 15 billion kilograms of rubbers are produced annually, and of that amount two thirds is synthetic…

Natural vs synthetic rubber

Natural rubber, coming from latex, is mainly poly-cis-isoprene containing traces of impurities. Although it exhibits many excellent properties, natural rubber is often inferior to synthetic rubbers, especially with respect to its thermal stability and its compatibility with petroleum products.

Synthetic rubber is made by the polymerization of a variety of petroleum-based precursors called monomers. The most prevalent synthetic rubbers are styrene-butadiene rubbers (SBR) derived from the copolymerization of styrene and 1,3-butadiene. Other synthetic rubbers are prepared from isoprene (2-methyl-1,3-butadiene), chloroprene (2-chloro-1,3-butadiene), and isobutylene (methylpropene) with a small percentage of isoprene for cross-linking. These and other monomers can be mixed in various proportions to be copolymerized to produce products with a range of physical, mechanical, and chemical properties. The monomers can be produced pure and the addition of impurities or additives can be controlled by design to give optimal properties. Polymerization of pure monomers can be better controlled to give a desired proportion of cis and trans double bonds…
