Collagen extracted from rabbit: Meat and by-products: Isolation and physicochemical assessment

Effect of pH on the Structure, Functional Properties and Rheological Properties of Collagen from Greenfin Horse-Faced Filefish (Thamnaconus septentrionalis) Skin

“…The EAI of collagen decreased from 386.61 ± 0.55 to 113.56 ± 3.94 m 2 /g as the pH was increased from 2 to 7.83, and then it increased to 421.89 ± 1.59 m 2 /g as the pH was increased from 7.83 to 10. The EAI for GHSC was found to be higher than the previously reported rabbit meat collagen (44.7 m 2 /g), rabbit skin collagen (46.6 m 2 /g), rabbit ear collagen (48.2 m 2 /g) [15], chicken feet collagen (71.4 m 2 /g) [31], and lamb slaughter by-product collagen (59.1 m 2 /g) [12]. Ngui et al (2021) [32] reported that solubility provides proteins with a better ability to diffuse into the oil-water interface, resulting in lower interfacial tension and improved protein emulsification properties.…”

“…Figure 7c,d show that FC decreased from 64.0 ± 0.3 to 12.0 ± 0.5% when the pH was increased from 2 to 7.83 and then increased to 62.0 ± 0.45% when the pH was increased to 10. The results for FC in this study were higher than sheep slaughter by-product collagen (9.58%) [12], rabbit meat collagen (9.2-11.7%) and rabbit skin collagen (4.2-9.2%) [15]. The FS of GHSC ranged from 62.5 ± 0.81 to 16.7 ± 2.9% for pH 2-10, with a minimum at pI, and the FS result of GHSC was higher than that of chicken feet collagen (11.7%) [31].…”

“…The emulsifying activity index of collagen of red stingray (Dasyatis akajei) skin collagen (61.06-117.11 m 2 /g) [13] was superior to that of bactrian camel (Camelus bactrianus) hoof collagen [14] and rabbit meat collagen (44.7 m 2 /g), rabbit skin collagen (46.6 m 2 /g), rabbit ear collagen (48.2 m 2 /g) [15] and lamb slaughter by-product collagen (59.1 m 2 /g) [12]. The emulsifying stability index of double-spotted pufferfish skin collagen (45.23-13.68 min) [9] was higher than that of rabbit meat collagen (9.8 min), rabbit skin collagen (9.8 min), and rabbit ear collagen (9.8 min) [15]. Because of the high demand and unique physicochemical properties of marine collagen, scientific and industrial interest in marine collagen is growing, and the marine collagen market value has been reported to reach USD 1055.2 million by 2026 [2].…”

“…The extraction yields of Megalonibea fusca swim bladders collagen (33.38%) [8] and double-spotted pufferfish (Takifugu bimaculatus) skin collagen (49.83 ± 1.85%) [9] were higher than those of cattle tendon collagen (2.4-6.2%) [10], pork skin collagen (11.38% ± 0.66%) [11] and sheep slaughter by-product collagen (12.05%) and lamb slaughter by-product collagen (18.0%) [12]. The emulsifying activity index of collagen of red stingray (Dasyatis akajei) skin collagen (61.06-117.11 m 2 /g) [13] was superior to that of bactrian camel (Camelus bactrianus) hoof collagen [14] and rabbit meat collagen (44.7 m 2 /g), rabbit skin collagen (46.6 m 2 /g), rabbit ear collagen (48.2 m 2 /g) [15] and lamb slaughter by-product collagen (59.1 m 2 /g) [12]. The emulsifying stability index of double-spotted pufferfish skin collagen (45.23-13.68 min) [9] was higher than that of rabbit meat collagen (9.8 min), rabbit skin collagen (9.8 min), and rabbit ear collagen (9.8 min) [15].…”

Investigation on mechanical, gas barrier, and biodegradation properties of graphene oxide reinforced bovine trimmings derived collagen biocomposite

“…The soil burial approach was used to conduct biodegradation investigations on Col-GO composite films. 21 In clearly labeled pots, garden soil was taken from Amar Ekushey Hall at KUET campus, Khulna-9203, Bangladesh. Specimens were planted under soil at 5 cm deep in each pot containing equal amount of soil.…”
