Aqueous two-phase purification of α-Amylase from white pitaya ( Hylocereus undatus ) peel in polyethylene glycol /citrate system: Optimization by response surface methodology

Application of Gelatin Incorporated with Red Pitaya Peel Methanol Extract as Edible Coating for Quality Enhancement of Crayfish (Procambarus clarkii) during Refrigerated Storage

“…Meanwhile, peel extracts are commonly used as biological preservatives in many food processes, especially in the aquatic product, to prolong shelf life including essential oils from tangerine peels and mango peel extracts and polyphenols from apple peels [6,11,12]. Edible coating can be used to protect phenolic compounds from oxidation by external factors such as the presence of light, oxygen, metal ions, pH, and high temperatures [13] and provide fresh food protection to prevent quality loss and weight loss. Several researchers have applied it to the storage of aquatic products [14][15][16].…”

Valorization of byproducts from tropical fruits: Extraction methodologies, applications, environmental, and economic assessment: A review (Part 1: General overview of the byproducts, traditional biorefinery practices, and possible applications)

“…Similarly, Shad et al. () purified α‐amylase from white pitaya peel in a system composed of salt and polyethylene glycol. Furthermore, the impact of the working variables was investigated.…”

“…The enzyme was highly selective for soluble starch, amylopectin, glycogen, and pulullan. Similarly, Shad et al (2018) purified -amylase from white pitaya peel in a system composed of salt and polyethylene glycol. Furthermore, the impact of the working variables was investigated.…”

Purification of a lectin from Cratylia mollis crude extract seed by a single step PEG/phosphate aqueous two-phase system

“…Partitioning in aqueous twophase system (ATPS) has been shown to be a powerful tool for separating and purifying mixtures of proteins [18][19][20] and is considered as a very attractive alternative to more conventional technologies such as chromatography. [21] ATPSs techniques are formed when two mutually incompatible hydrophilic solutes are dissolved in water above a certain critical concentration [22][23][24][25] and have successfully applied in the purification of different biological materials such as cells, virus, organelles, nucleic acids, proteins, and enzymes. [20][21][22][23][24][25][26] Since some of techniques have been used to purify lectins, to facilitate the development of extraction process in ATPSs several basic steps should be followed.…”

At first the selection of the ATPS, since polymer-polymer or polymersalt systems can be used.…”
