Gelatin derived from sheepskin (GSS) is a promising biomaterial for edible, biodegradable films, but exhibits poor water resistance, mechanical weakness, and brittleness. This study developed ultrasound-assisted composite films based on GSS and konjac glucomannan (KG; 0–75% w/w) to enhance their functionality. The ultrasonic treatment (40 kHz, 15 min) improved homogeneity and reduced structural defects. KG incorporation significantly increased film thickness from 0.031 mm to 0.038 mm and tensile strength from 0.5118 MPa to 0.9601 MPa, while reducing water vapor transmission from 2.6974 g m⁻² day⁻¹ to 1.7304 g m⁻² day⁻¹ and water activity from 0.4526 to 0.3084. Swelling decreased from 4.77% to 3.82%, whereas water resistance improved from 95.23% to 96.18%. The optimal formulation (25% KG) provided a balance between strength, flexibility, and hydrophobicity. FTIR confirmed intermolecular hydrogen bonding between GSS and KG, and ultrasound promoted uniform dispersion and denser microstructures. These findings highlight ultrasound-assisted GSS/KG films as sustainable, protein-polysaccharide-based materials with superior physicochemical and barrier properties for eco-friendly food packaging applications.

This study evaluated the application of yellow mealworm ( Tenebrio molitor ) larvae protein extract (YMPE) as a clean-label cryoprotectant for frozen Pacific white shrimp ( Litopenaeus vannamei ), with emphasis on its underlying mechanism. Proteomic profiling identified 12 antifreeze protein-like peptides containing conserved ice-binding motifs (TCTxSxxCxxAx), supporting the cryoprotective potential of YMPE. During dose optimization, shrimp treated with 0.5% YMPE exhibited the highest weight gain (5.57%) and lowest freezable water content (59.67%) (P < 0.05). The cryoprotective efficacy of YMPE was further evaluated over five freeze–thaw cycles in comparison with distilled water and mixed phosphate. YMPE significantly mitigated quality deterioration by enhancing water retention, preserving protein functionality (higher Ca<sup>2+</sup>-ATPase activity), and reducing lysosomal enzyme leakage relative to the control (P < 0.05). Microstructural analysis revealed reduced muscle fiber disruption, characterized by fewer inter-fiber gaps. Mechanistically, YMPE may exert cryoprotective effects through a multimodal mechanism involving ice recrystallization inhibition and formation of a protective protein matrix. Although less effective than mixed phosphate, YMPE consistently improved all quality parameters compared with the control. These findings highlight the potential of insect-derived protein extracts as a novel, biologically based alternative to phosphate additives in seafood processing and provide a foundation for future industrial application.

Djenkol peel is an agricultural by-product containing valuable bioactive compounds. The direct use of its extract faces challenges related to stability and sensory acceptance. This study aimed to investigate the effect of djenkol peel extract (DPE) on the encapsulation efficiency (EE) using liposomes. The physicochemical properties, antioxidant activities, and cytotoxicity of the obtained liposomes were evaluated. DPE (0, 0.25, 0.50, 0.75, and 1.00 %, w/v) was encapsulated using phospholipid/cholesterol as the wall material. The highest EE (66.69 %) was observed in the liposomes loaded with 0.25 % (w/v) DPE (LE-0.25DPE) (P < 0.05). All DPE-loaded liposomes displayed nanometer-scale particle sizes (78.94–135.60 nm) and negative zeta potentials (−52.60 to −57.50 mV). Encapsulation of DPE in liposomes can mask its undesirable color. Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and differential scanning calorimetry (DSC) revealed changes in the physicochemical and thermal properties of LE-0.25DPE. Additionally, LE-0.25DPE showed increased DPPH radical-scavenging activity (DPPH-RSA) and ferric reducing antioxidant power (FRAP) in a dose-dependent manner (250–2000 μg/mL). In vitro Caco-2 cell viability test, LE-0.25DPE at 0.1–1 μg/mL exhibited no cytotoxicity compared to the control (P < 0.05). Thus, DPE-loaded liposomes demonstrate potential as a functional food ingredient with high bioactivity.

Clown featherback (Chitala ornata) is a freshwater fish important in the cuisine of Thailand and other Southeast Asian countries. It has a short marketable life due mainly to poor gelling characteristic even when stored in ice. This deterioration has been associated with muscle autolysis. The research was aimed to investigate the autolysis of clown featherback muscle (CFM). To test autolysis, mince from CFM was incubated in a temperature controlled water bath for 60 min at 5, 10, 20, 30, 40, 50, 60, 65, 70, 75 or 80 °C at pH levels over the range of 2-11. The results showed that the highest autolytic activity was at 70 °C and it occurred at pH levels of 4 and 7, with pH 4 showing the highest autolysis. CFM was incubated with its crude enzyme counterpart at the physiological pH (6.73) at both 4 °C and 25 °C. Degradation of natural actomyosin showed that after incubation at either temperature myosin heavy chain was susceptible to hydrolysis indicating that autolysis of CFM took place even at low temperature as affected by its endogenous proteases. The effects of several protease inhibitors were tested and autolysis at the physiological pH (6.73) was strongly inhibited by 10 μM pepstatin A (20.3% inhibition), which had significantly higher inhibitory activity (P < 0.05) among the protease inhibitors tested. This suggests that aspartic protease was the major proteinase in CFM.

This study aimed to comprehensively investigate and characterize the physical, mechanical, and molecular properties of gelatin films made from goat skin incorporated with konjac glucomannan. The study involved three treatment groups, labeled GG/KG1, GG/KG2, and GG/KG3, which included konjac glucomannan at concentrations of 0, 10, and 20% (w/w), respectively. Glycerol at 20% (w/w) was also included as a plasticizer. All samples underwent homogenization and ultrasonic treatment. The addition of konjac glucomannan to the gelatin-based film resulted in changes such as increased thickness (0.033-0.093 mm), opacity (0.9910-1.0433 mm-1), color L* (92.45-92.77), color difference (48.13-48.38), swelling (65.53-69.47%), and contact angle (86.92-127.85o). Conversely, a decrease was observed in water activity (0.521-0.463 Aw), moisture content (9.87-9.62%), tensile strength (0.0171-0.0118 N/mm2), elongation at break (5.91-4.52%), young’s modulus (0.0029-0.0026 N/mm²), WVTR (118.99-116.82 g/m². day), transparency (81.59-67.33%), and water resistance (34.47-30.53 %). Additionally, the peaks of amides A, B, I, II, and III exhibit both a shift and an increase in intensity, suggesting structural modifications and molecular interactions. The microstructure also indicated the presence of goat skin gelatin and konjac glucomannan cross-linked in the film formation. Therefore, the addition of konjac glucomannan modifies gelatin-based films, enhancing their suitability for food packaging.

In this study, we investigated the impact of lipid oxidation on the discoloration of Sawai (Pangasianodon hypophthalmus) lipids and proteins. Sawai microsomes, liposomes, and salt-soluble myofibrillar proteins were prepared and subjected to lipid oxidation process. The results revealed that the levels of thiobarbituric acid-reactive substances, yellowness (as indicated by b* values), and pyrrole compounds increased when Sawai liposomes and microsomes were oxidized using iron and ascorbate. Meanwhile, the levels of free amines decreased, particularly as the iron content (25∼100 μM) and incubation time (0∼20 h) increased. The impact of oxidized liposomes at different levels (1, 2, and 5%) on the salt-soluble Sawai myofibrillar proteins was also evaluated. The findings revealed that lipid oxidation products reduced the sulfhydryl content and increased the surface hydrophobicity and carbonyl content of the salt-soluble Sawai myofibrillar proteins. These results imply that the formation of yellow discoloration in Sawai muscle could be due to nonenzymatic browning reactions occurring between lipid oxidation products and amines in the muscle protein.

Effect of Ya-nang leaves (Tiliacora triandra) powder (YLP) (0.5-2.0%) on qualities and lipid oxidation of tilapia emulsion sausages during 21 days of refrigerated storage was investigated. Control sample had lower fiber content than samples added with YLP (p<0.05) at day 0 of storage. YLP treated samples (1.0-2.0%) revealed lower L* value but higher b* and ΔE* values, compared to the control samples (p<0.05). With the addition of YLP, peroxide value (PV) and thiobarbituric acid-reactive substances (TBARS) value in the sausages were retarded effectively, compared to control sample (p<0.05), especially when the YLP at high contents were used. Addition of YLP were also effective in retarding the formation of fishy odor in the samples, compared to control sample (p<0.05). Samples treated with YLP had higher hardness and springiness, compared with control sample during storage (p<0.05). YLP had no detrimental effect on the sensory attributes of sausages. This study pointed out that YLP can be utilized in sausages to enhance quality.

The aim of this study was to produce collagen hydrolysate with antioxidant activity. Pepsin soluble collagen (PSC) isolated from the skin of Pharaoh cuttlefish (Sepia pharaonis) was used as a substrate for hydrolysis at 25°C and pH 7.5 by using collagenase from Clostridium histolyticum. The result showed that rapid hydrolysis was observed within the first 90 min with a degree of hydrolysis (DH) approaching 35%. Thereafter, a slower rate of hydrolysis was generally observed. An increase in DH was generally observed with increasing enzyme concentration. When log10 (collagenase concentration) versus DH (%) was plotted, a linear relationship was found with a coefficient of determination (R2) of 0.9863. Electrophoretic study of collagen hydrolysates with 10% DH, 20% DH, and 30% DH revealed that their major peptides had molecular weights (Mr) ranging from 6.5 to 10.3 kDa; and 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activities. The ferric reducing activity power (FRAP) of collagen hydrolysates with 20% DH and 30% DH were similar (p > 0.05). Chelating activity of collagen hydrolysates with 20% DH was negligible and for 10% DH and 30% DH it was not detectable. Given these findings, Pharaoh cuttlefish skin, a byproduct of cuttlefish processing, is a promising source material for production of collagen hydrolysate with antioxidant activities.

This study evaluated Ganoderma lucidum G2 spores (GLS) using various processing techniques: vibrating milling, ball milling, and autoclaving. Broken GLS via vibrating and ball milling showed higher lipid content (22.89% and 22.50%) but lower L*, a*, and b* values compared to intact GLS. Vibrating milling achieved the highest sporoderm-broken rate (98.27%). Ball milling resulted in the highest lipid oxidation. Vibrating milling yielded the highest bioactive compounds, and both methods increased DPPH-RSA values. Differential scanning calorimetry indicated varying T<inf>max</inf> values: non-broken GLS (106.56 °C), vibrating milling (92.77 °C), ball milling (97.58 °C), and autoclaving (109.35 °C). FT-IR spectra showed triterpenes, polysaccharides, and fatty acids. X-ray diffraction and Fourier transform infrared spectroscopy revealed increased crystallinity with vibrating milling (37.12% to 47.99%). Both milling methods altered GLS structure to a disintegrated, pancake-like form. Scanning electron microscopy with energy-dispersive X-ray spectroscopy indicated significant carbon and oxygen concentrations. This study provided crucial insights for utilizing GLS.

This study aimed to develop edible films based on sheepskin gelatin, incorporating soybean oil as a plasticizer. Treatment was divided into three groups, namely GO1, GO2, and GO3, each containing soybean oil at 0%, 2.5%, and 5% (v/v). A homogenizer was used to combine gelatin from sheepskin and soybean oil. Then, ultrasound was applied to form edible films. The results showed that adding soybean oil increased the films thickness, opacity, water resistance, and moisture content. However, it decreased the transparency and swelling of the films. It also did not affect the water activity of the films. The GO3 sample had the highest L∗ value, a∗, and b∗ values. It also had the lowest ΔE value, which indicated that it was close to the color of the original material. The peak wavenumbers changed after adding soybean oil, especially in the amide A and fingerprint regions. A notable shift occurred at the peak wavenumber of 1744.94 cm-1, which represented the vibrational stretching of C=O in triglycerides. The produced edible film had low flexibility, but it serves as a valuable reference for developing safe and practical films using gelatin sheepskin with natural oils as plasticizers.
