“…Therefore, this dose-dependent study was performed to evaluate the effects of astaxanthin on antioxidant status in meat, plasma, and their relationship with meat quality and color. However, the effects of astaxanthin on the scavenging capacity against DPPH and ABTS in broiler meat have not been studied, a previous study showed that the DPPH or ABTS radical-scavenging activity of astaxanthin was 72 or 220 times greater than ascorbic acid, as an antioxidant factor, in shrimp shell [ 37 ]. The enhanced ABTS and DPPH scavenging capacity due to astaxanthin supplementation was accompanied by an increase in tissue antioxidant capacity measured by TAC in the leg muscle, implicating the decrease of oxidative tissue damage in the presence of astaxanthin.…”

This study investigated the effect of dietary astaxanthin (AST) on the meat quality, antioxidant status, and immune response of chickens exposed to heat stress. Four hundred and eighty male broilers were assigned to four treatments including AST0, AST20, AST40, and AST80 with 0, 20, 40, and 80 ppm astaxanthin supplementation levels, respectively. There was a linear decrease of malondialdehyde (MDA) in leg muscle. Catalase and superoxide dismutase levels in the plasma were linearly increased. There was a linear increase in the level of total antioxidant capacity in the leg muscle. The 3-ethylbenzothiazoline-6-sulfonate reducing activity of leg muscle was significantly increased in the AST80 treatment. The AST40 treatment showed an increase in 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity of leg muscles. Breast meat redness and yellowness were linearly increased. The astaxanthin-supplemented treatments exhibited lower drip loss and MDA concentration of leg muscle compared with the AST0 treatment at days 3 and 9 of storage. Supplementation of 40 or 80 mg/kg astaxanthin significantly decreased heat shock protein (HSP)27, HSP70, tumor necrosis factor alpha, and interleukin-6 expression in the livers. The feather corticosterone was significantly lower in the astaxanthin-supplemented treatments than in the AST0 treatment. In conclusion, astaxanthin decreased the hyperthermic stress level and improved meat quality, and antioxidant status of chickens exposed to heat stress.

“…The NACOS generally have not been as commercialized as COS, owing to the high cost associated with the process of re-acetylation from COS by chemical or enzymatic methods [40]. As more efficient chitinases continue to be developed, the traditional methods of NACOS production through chitin deacetylation, the hydrolysis of chitosan, and the re-acetylation of COS would be abandoned and replaced by the direct chitinase hydrolysis of chitin or crustacean shells, which will would facilitate the imminent commercialization of NACOS [32,33]. Until now, the bioactivities of NACOS and their underlying mechanisms have been poorly understood and lagged far behind our understanding of COS mechanisms.…”

“…The NACOS with a low DP (LNACOS) were prepared from colloidal chitin by the chitinase, Chit46, as previously reported [32]. The NACOS with a high DP (HNACOS) were prepared from shrimp shells [33]. The composition and de-acetylation degree (DA) of COS, LNACOS, and HNACOS are listed in Table 1.…”

“…Combined with aspartic proteases, the convenient commercial enzymatic production of NACOS from shrimp shells has also been developed, omitting all chemical processing steps of traditional NACOS production. [ 33 ]. With this novel method, two NACOS samples, low DP NACOS (LNACOS) and high DP NACOS (HNACOS), are produced, and they show different immune enhancement and anti-inflammation effects.…”

The ongoing development of new production methods may lead to the commercialization of N-acetyl chitooligosaccharides (NACOS), such as chitosan oligosaccharides (COS). The bioactivity of NACOS, although not well detailed, differs from that of COS, as they have more acetyl groups than COS. We used two enzymatically produced NACOS with different molecular compositions and six NACOS (NACOS1–6) with a single degree of polymerization to verify their immunomodulatory effects on the RAW264.7 macrophage cell line. We aimed to identify any differences between COS and various NACOS with a single degree of polymerization. The results showed that NACOS had similar immune enhancement effects on RAW264.7 cells as COS, including the generation of reactive oxygen species (ROS), phagocytotic activity, and the production of pro-inflammation cytokines (IL-1β, IL-6, and TNF-α). However, unlike COS and lipopolysaccharide (LPS), NACOS1 and NACOS6 significantly inhibited nitric oxide (NO) production. Besides their immune enhancement effects, NACOS also significantly inhibited the LPS-induced RAW264.7 inflammatory response with some differences between various polymerization degrees. We confirmed that the NF-κB pathway is associated with the immunomodulatory effects of NACOS on RAW264.7 cells. This study could inform the application of NACOS with varying different degrees of polymerization in human health.

“…In the aqueous phase, the best yield of the simplest amino acid comes from glycine (Kaspar and Reichert 2013 ). The recovery of 91% protein named Astaxanthin found in shrimp shell waste by enzymatic conversion was performed by (Deng et al 2020 ) along with the recovery of other by-products such as chitin. The recovery of collagen protein powder separated from chromium leather scrap waste was studied, revealed to be containing different amino acids and displaying a low concentration of mineral salt that can be used as fertilizer (Dang et al 2019 ).…”

Economic growth and the rapid increase in the world population has led to a greater need for natural resources, which in turn, has put pressure on said resources along with the environment. Water, food, and energy, among other resources, pose a huge challenge. Numerous essential resources, including organic substances and valuable nutrients, can be found in wastewater, and these could be recovered with efficient technologies. Protein recovery from waste streams can provide an alternative resource that could be utilized as animal feed. Membrane separation, adsorption, and microbe-assisted protein recovery have been proposed as technologies that could be used for the aforementioned protein recovery. This present study focuses on the applicability of different technologies for protein recovery from different wastewaters. Membrane technology has been proven to be efficient for the effective concentration of proteins from waste sources. The main emphasis of the present short communication is to explore the possible strategies that could be utilized to recover or restore proteins from different wastewater sources. The presented study emphasizes the applicability of the recovery of proteins from various waste sources using membranes and the combination of the membrane process. Future research should focus on novel technologies that can help in the efficient extraction of these high-value compounds from wastes. Lastly, this short communication will evaluate the possibility of integrating membrane technology. This study will discuss the important proteins present in different industrial waste streams, such as those of potatoes, poultry, dairy, seafood and alfalfa, and the possible state of the art technologies for the recovery of these valuable proteins from the wastewater.
