Collagenous derivatives (collagen, gelatin, and collagenous hydrolysate (CH)) are extensively used across the food, biomedical, and pharmaceutical industries. Traditionally, these have been sourced from porcine, bovine, and fish due to their ready availability and biocompatibility. However, conventional collagenous derivatives face ongoing challenges regarding sustainability, resource intensity, and socio-cultural perceptions. This has led to the exploration of alternative collagenous derivatives from unconventional sources, with a primary focus on evaluating their potential for yields, extractability, and functional properties, all of which are fundamental for future scale-up and alternative applications. This review summarizes alternative collagenous derivatives from unconventional animals, including amphibians, mollusks, echinoderms, insects, unconventional fish and byproducts, and reptiles. Their structures, extraction techniques, functional properties, and potential applications are comprehensively summarized, showcasing their ability to complement or even surpass conventional sources in specific uses. Additionally, the challenges and prospects for industrial application, emphasizing the sustainability of meeting growing collagen demand and encouraging further research into these promising alternative sources, were discussed. Unconventional collagenous derivatives demonstrate excellent and unique characteristics as alternatives to conventional ones. Type I collagen from amphibians, reptiles, and mollusks had superior thermal stability. Unconventional gelatin and CH also possess various bio-functionalities that can enhance their potential applications. The relatively low extraction yield could be addressed by increasing the concentration of chemicals or extraction time and incorporating green technology without causing an adverse impact on the quality. These findings indicate the potential applications of unconventional collagenous derivatives as food ingredients and supplements.

Fish gelatin (FG) is a promising alternative to mammalian gelatin but is limited by poor gelling ability, low gel strength, and inability to set at room temperature. This study evaluated the effects of furcellaran (FUR), a gelling agent, on the structural and physicochemical properties of FG gels at different substitution levels (25–100%). The addition of 25% FUR improved gel strength and hardness. However, higher FUR levels (>50%) led to reduced springiness and increased syneresis. Intermolecular force measurements revealed that ionic and hydrogen bonds were crucial in the FG/FUR gel system, with higher levels of FUR promoting stronger ionic and hydrogen bonding. Color changes were observed with decreased L* and increased b* and ∆E* values as FUR levels rose. Gelling and melting points also increased proportionally with FUR content. Microstructural analysis showed denser gel networks with smaller gaps upon FUR incorporation. SAXS analysis confirmed enhanced structural conformation with higher FUR levels. An appropriate level of FUR added (25%) could therefore improve gelling properties via increasing gel strength and gelling temperature without negative effects on springiness and syneresis of resulting gel.

The comparison of the Sanim (SN) and Srithong (ST) varieties of the farmed apple snail Pomacea canaliculata as an alternative protein source has shown that ST contained more hydroxyproline and possessed a greater firmness than SN. Nevertheless, both varieties yielded similar protein contents of 20.90–23.07 % and exhibited similar texture, color, cooking yields and cooking losses after cooking. Good palatability with high liking score was obtained from both snail meat samples, particularly color, texture, and overall attributes. Snail meats possessed good nutritive value with an amount of protein and low fat content, whereas SN contained higher protein and total energy(P < 0.05). Other nutritionally useful chemicals (such as calcium, sodium, iron, vitamins B1 and B2) are present. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) results discovered that myosin heavy chain, paramyosin, and actin were the prevalent protein components. Differences in nitrogen content distribution were observed between SN and ST, in which alkaline-soluble protein was the major fraction. Amino acid composition and fatty acid content varied regarding snail varieties with a large amount of essential amino acids and good source of MUFA and PUFA. Therefore, both farmed SN and ST snails could be an effective alternative protein source with a significant amount of nutritive value.

Excessive levels of sodium consumption over the recommended human daily intake level is a global issue. Developing novel low-sodium products to address this issue is challenging. Moreover, there is little research on the use of stealth reduction approaches in reduced sodium seasoned green mussel, representing an additional opportunity for advancement in developing novel products in the seafood processing industry. Thus, this study aimed to develop a seasoned green mussel (Perna viridis) product with a reduced sodium content. The study consisted of two parts: The first part studied two types mussel seasonings (‘Pad-char’; PC and ‘Prik-Pao’; PP) with various sodium reduction levels (30, 70, or 100 %). The difference in taste profiles was confirmed using an electronic tongue technique and consumer acceptance trial. Green mussels seasoned with PC were preferred over those seasoned with PP. Green mussels seasoned with PC at a 30 % sodium reduction level (PC-30 %) received the second highest overall liking score, following the standard, and had a sodium content of 623.80 mg/100 g. Furthermore, PC-30 % was rich in other essential nutrients such as protein and vitamin A. The second aim was to study the shelf-life of the PC-30 % products with storage at 4 ± 1ºC for 12 days. During storage, the PC-30 % sample developed a tough texture, as indicated by higher hardness and chewiness values, along with increased pH and total volatile-based nitrogen. The microbial loads indicated that the shelf-life of the PC-30 % product stored at 4 ± 1ºC was 9 days. This suggests that reducing sodium in mussels through seasoning is feasible while maintaining acceptable sensory scores, but shelf-life challenges must be addressed before bringing these products to market.

Biodegradable films, featuring eco-friendly attributes, offer a promising solution to environmental pollution and ecological challenges, serving as a viable alternative to synthetic polymer packaging films. This study investigates the washing process with various solvents (ethanol and water) and washing cycles (1 and 3 times) on the properties of gelatin capsule waste films (GCWF). The washing process could improve properties such as tensile strength, thermal properties, transparency value, and solubility by eliminating oil droplets from the raw materials. The GCWF washed by ethanol (GCWF Alc) exhibited higher tensile strength (TS), thermal properties, and transparency value compared with GCWF washed by water (GCWF W). Increasing the number of washing cycles could also enhance the efficiency of eliminating oil droplets from the raw materials. The complete degradation of GCWF in soil was observed on day 15 after burial. FTIR spectroscopy revealed differences in bands and patterns between control film (GCWF) and washed films (GCWF Alc and GCWF W). These findings highlight the potential of the washing process in enhancing film properties, and the utilization of gelatin capsule waste as biodegradable films could be further developed for food packaging applications, contributing to environmentally friendly technologies

The organoleptic and nutritional properties of giant river prawns cultivated in two aquaculture systems, the vertical-recirculating aquaculture system (RAS) and the traditional pond (Pond), were examined. Proximate compositions of RAS and Pond did not show significant differences (P > 0.05). Regarding organoleptic properties, the color of RAS meat was noticeably paler, with reduced blueness, as indicated by higher L* and b* values (P < 0.05). This correlated with lower astaxanthin levels (21.23 μg/g) of the RAS compared to Pond (56.02 μg/g) (P < 0.05). RAS also had lower levels of adenosine monophosphate (AMP), inosine monophosphate (IMP), and other desirable volatiles, including aldehydes, suggesting a reduced desirable flavor/taste intensity. However, RAS had higher levels of tasty amino acids (umami/sweetness) such as Glu/Gln and Ala (P < 0.05). In terms of nutrition properties, Pond provided better fatty acid (FA) profiles, as indicated by a higher ratio of polyunsaturated fatty acids/saturated fatty acids (PUFA/SFA) and a higher proportion of omega-3 fatty acids (n-3) (P < 0.05). Moreover, Pond also displayed a more balanced amino acid (AA) composition as indicated by the predicted protein efficiency ratio (P-PER) and the Leu/Ile ratio. Nevertheless, the FA and AA profiles of RAS still met satisfactory levels according to respective standards. In summary, the findings demonstrated that the alternative RAS provided adequate nutritional value but exhibited distinct organoleptic characteristics compared to the traditional pond. These differences may potentially impact customer acceptance and should be taken into consideration during the development of alternative aquaculture systems for this prawn species.

The demand of plant-based protein has been remarkably increased, leading to the development of various plant-based protein products. Supplementation of synbiotic is an effective approach to improve food function. This study aimed to develop the formulation of plant-based protein product supplemented with synbiotic which provides high survivability of probiotic through various harsh conditions. Pea protein isolate (PPI), inulin, and glycerol at ratio 2:1:1 was supplemented with probiotic strain (Lactobacillus acidophilus TISTR1388) to develop as encapsulated synbiotic plant-based protein powder (SPBP). The developed formulation provided probiotic survival rate after freeze-drying and gastro-intestinal (GI) tract conditions at 95.0±2.1% and 62.4±6.1%, respectively. Whereas, probiotic as free-cells showed survival rate after freeze-drying at 78.9±0.4% and no survival cell was observed after GI tract digestion. Scanning Electron Microscope (SEM) analysis demonstrated SPBP's remarkable capacity to perfectly entrap probiotic cells with no visible cell damage. Herein, the stability of the SPBP was tested through various pH levels (3, 5, 7, and 9) and temperature levels (6±2°C, 26±2°C, and 55±2°C) in order to investigate the possibility of applying this product to various food categories. Results showed that developed SPBP survived through all tested pH and temperature levels for 3 h at least 88.9±6.6%. Shelf-life evaluation showed that SPBP provided survival rate of probiotic cells up to 96.2±2.4% an a<inf>w</inf> of 0.09±0.01 after 12 weeks of refrigerated storage. Overall, results revealed that SPBP had a strong possibility of being employed as a probiotic stabilizer that may be further developed for a functional food product.

Microbial profiles, autolysis rates, and textural characteristics of giant river prawn (Macrobrachium rosenbergii) cultured in a vertical farming with a recirculating aquaculture system (RAS) were compared to those of prawns cultured in a traditional pond system (Pond). Bioinformatics analysis revealed significant differences in the quantity and diversity of microbial communities between RAS and Pond. Firmicutes were the dominant phylum found in both samples but at higher levels in Pond (P < 0.05). Conversely, Tenericutes, Proteobacteria, and Actinobacteria, known as healthy microbiomes, were more abundant in RAS (P < 0.05). At the genus level, Enterococcus, recognized for its potential to improve colonization resistance against pathogens in the gut, was detected at higher levels in RAS (P < 0.005). This variation in microbiota might affect the difference in autolysis rates and textural properties between these two samples. RAS had a lower autolysis rate at all temperatures (4, 15, 25, and 35 °C) (P ˂ 0.05), consistent with the lower TCA-soluble peptide (157.61 μmol tyrosine equivalent/g sample). The differences in textural characteristics of these two prawns were observed. RAS had more water holding capacity (WHC) (80.07%) but lower drip loss (15.75%) and cooking loss (28.36%) than Pond (73.77, 17.84, and 31.20%, respectively) (P ˂ 0.05). From TPA results, RAS showed higher chewiness and gumminess than Pond, indicating a firmer texture, which is a desirable characteristic, particularly in fresh prawn. Overall, the findings indicated an improvement in microbial profiles, which further translated into economic benefits in terms of yield production and muscle quality, particularly texture, of prawn cultured in a recirculating aquaculture system as an alternative approach.

Butterfly pea is a natural color source used in food and dessert. This study optimized ultrasound-assisted extraction with ethanol for pigments from butterfly pea flowers (BPF) using a Box-Behnken method. Key factors explored were solid-to-solvent ratio, ultrasound extraction time, and ethanol concentration. The extracted compounds were evaluated for extraction yield (EY), total phenolic content (TPC), total anthocyanin content (TAC), and DPPH antioxidant activity. EY increased significantly with reduced ethanol concentration. Optimal conditions were predicted and experimentally validated. BPF extracts showed distinct absorption wavelengths at different pH levels. BPF extract was used in coconut milk jelly, resulting in the lowest b* value. These findings highlight the value of optimal ultrasonic-assisted extraction for enhancing BPF's natural colorant extraction and promoting sustainable use in food and dessert applications.

The incidence of non-communicable diseases (NCDs) caused by excessive sodium intake is becoming an important issue that many researchers have investigated. Processing is an effective way to add value to underutilized fish species. Thus, the objective of this research was to develop a fish snack (Keropok) using reduced sodium. Two types of alternative sodium chloride (NaCl) were used, namely potassium chloride (KCl) and calcium chloride (CaCl<inf>2</inf>) with substitution at levels of 15, 30, and 45 % (w/w). The results indicated that substitution of NaCl with KCl or CaCl<inf>2</inf> in the product had a negative effect on the cooking yield (%) (P<0.05). Using 55 % NaCl with 45 % KCl (B3) in Keropok had a consumer acceptance score similar to the control formula (P>0.05) and the lowest sodium content (P<0.05). After storage at 4 °C for 21 days, the microbial loads (Bacillus cereus, Escherichia coli, mold, Staphylococcus aureus, yeast) in B3 satisfied the requirements of the Thailand Community Product Standard (107/2011). In addition, increasing the storage time did not affect the texture of the product (hardness, gumminess, chewiness and cohesiveness) nor consumer acceptance (P>0.05). B3 was rich in nutrients (macromolecules and micromolecules) that are essential to the human body. Therefore, Kerepok (55 % NaCl with 45 % KCl: B3) could be considered as a healthy snack.
