The optimization of antioxidant and anti-tyrosinase activity during jellyfish hydrolysate preparation was studied using a response surface methodology (RSM) with face-centered composite design. influence the hydrolysis duration enzyme concentration on IC50 DPPH ABTS radical scavenging activity, ferric-reducing power (FRAP), degree (DH), yield, value tyrosinase inhibitory were determined. optimum conditions for production alcalase (JFAH), flavourzyme (JFFH), or papain (JFPH) achieved at times...
Mantis shrimp (Oratosquilla nepa) exoskeleton, a leftover generated after processing, was used as starting material for chitosan (CS) production. CS extracted with different deacetylation times (2, 3 and 4 h), termed CS−2, CS−3 CS−4, respectively, their characteristics antimicrobial film properties agarose (AG) were investigated. Prolonged time increased the degree of (DDA: 73.56 ± 0.09–75.56 0.09%), while extraction yield (15.79 0.19–14.13 intrinsic viscosity (η: 3.58 0.09–2.97 0.16 dL/g)...
Tuna blood (TB) was subjected to enzymatic hydrolysis. The effects of the relationship hydrolysis time (30–180 min) and enzyme concentration (0.5–3.0% w/w protein) on degree (DH), yield, antioxidant angiotensin-I-converting (ACE) inhibitory activities were determined. response surface methodology (RSM) showed that TB hydrolysis’s optimum conditions for 180 min Alcalase, Neutrase or Flavourzyme at 2.81%, 2.89% 2.87% protein, respectively. hydrolysates with good DH (40–46%), yield (3.5–4.6%),...
Sea cucumber is rich in protein that can be used to prepare a potential derived bioactive peptide for antioxidant and protective effect against UV-B induced skin cell damage. This study aimed optimize preparation of sea hydrolysate with both activities using three commercial enzymes response surface methodology (RSM) face-centered central composite design (face- centered CCD). Hydrolysis time concentration enzyme effects on the degree hydrolysis (DH), yield, hydrolysates were determined. The...
ABSTRACT Effect of whey protein concentrate (WPC) in combination with calcium chloride (50 mmol/kg) on the gel properties surimi produced from goatfish ( Mulloidichthys martinicus ) was investigated. Breaking force and deformation both kamaboko (40/90C) modori (60/90C) increased increasing WPC (0–3%) P < 0.05). Myosin heavy chain (MHC) band intensity all gels more retained as concentration increased. The coincidental increase water‐holding capacity obtained, however, whiteness slightly...
Although protein isolates have been proven as a potent raw material for hydrolysate preparation, the fishy odour associated with lipid oxidation is still detected. The remaining haemoglobin (Hb) in can effectively induce oxidation, leading to formation of resulting hydrolysate. aim this study was elucidate impact Hb different forms, oxyhaemoglobin (oxy-Hb) and methaemoglobin (met-Hb), on development during hydrolysis isolates.During isolate up 120 min, non-haem iron content, peroxide value...
Abstract Fish protein hydrolysates (FPH) have gained increasing attention as nutritious fish products. Lipid oxidation associated with fishy odor in FPH limits its utility. Thus, an appropriate pretreatment of mince prior to hydrolysis by lowering pro-oxidants and lipid substrates could tackle such a problem. Different pretreatments Nile tilapia minces including (1) washing (W), (2) membrane removal (W-MR), (3) washing/membrane followed acid or alkaline solubilization (W-MR-Ac W-MR-Al) were...
Characteristic and antioxidant activity of the extracts from freshwater macroalgae (C.glomerata) as influenced by extraction media, i.e., water or ethanol (20-100%, v/v) were studied.The highest yield (28.0%) was obtained when used.Ethanolic had significantly lower yields (2.98-15.5%)(P<0.05).However, total phenolic chlorophyll contents in extract.Among all extracts, 60% ethanolic extract (E60) activities, including DPPH ABTS radical scavenging ferric reducing power metal chelating...
Impact of prior chlorophyll removal (PCR) and drying methods (freeze- oven-drying) on characteristics antioxidant activities the ethanolic extracts (EEs) from Cladophora (C.) glomerata, freshwater macroalgae, were investigated. The extraction yields found in range 7.18%–13.15% with total phenolic (TPC) (TCC) contents 19.40–25.69 mg GAE/g dry extract 3.58–7.94 mg/g extract, respectively. Yield, TPC TCC decreased when dechlorophyllization was implemented before extraction, regardless method (p...
Summary The research was aimed to study the impact of various treatments on characteristics bio‐calcium from hybrid catfish bone. Bio‐calcium bones (raw bone) prepared using several 4 steps including high‐pressure water jet process (washed bone), soaking in alkaline solution (protein removal), ethanol immersion (lipid bleaching and grinding obtain powder. obtained had a yield 14.46 g 100 −1 . low protein, fat moisture contents but high ash content ( P ≤ 0.05). rich calcium phosphorus....
