Purification and characterisation of a zinc-binding peptide from oyster protein hydrolysate

Fractionation and identification of Alaska pollock skin collagen-derived mineral chelating peptides

“…The IMAC purification approach has previously been used to isolate mineral chelating peptides from a wide range of food sources. These include oyster (Chen et al, 2013), sesame (Wang, Li, & Ao, 2012), soybean (Lv et al, 2009) and chickpea (Torres-Fuentes, Alaiz, & Vioque, 2012).…”

“…Numerous mineral chelating peptides derived from marine products and byproducts have been reported in the last decade. These include peptides from oyster (Chen et al, 2013), anchovy (Wu, Liu, Zhao, & Zeng, 2012), hoki (Jung & Kim, 2007) and pollock (Guo, Hou, Li, Zhang, & Zhao, 2013).…”

In vitro assessment of the multifunctional bioactive potential of Alaska pollock skin collagen following simulated gastrointestinal digestion

“…Metal‐chelating peptides have been identified as potential functional ingredients to improve mineral bioavailability. Metal‐chelating peptides derived from a variety of fish byproducts have been reported in the last decade, including peptides from pollock, oyster, anchovy and hoki proteins. ACE‐inhibitory peptides have received special attention because of their potential to control hypertension .…”

Properties of casein hydrolysate as affected by plastein reaction in ethanol-water medium

“…This result was consistent with the result reported by Wang et al (2011), who found that enzymatic hydrolysis led to the lower zinc-binding activity of the obtained yak casein hydrolysates (more free amino groups) than native yak casein (less free amino groups). Another support was found in a recent study in which the zinc-binding capacity of a zinc-binding peptide from oyster protein hydrolysate was found to be impacted by in vitro simulated digestion of three proteases (Chen et al 2013). The unfavourable impact of proteolysis (or plastein reaction) on the zinc-binding capacity of a peptide (or protein hydrolysates) resulted from the damage to the original spatial structure of the zinc-binding peptides, which could form stable complexes with metal ions (Harding et al 2010).…”
