Cooked Antarctic krill (AK) was sprayed with antioxidants, followed by hot air drying (HAD) to produce AK meal (AKM). The antioxidants could alleviate color darkening, reduce oxidation of lipids and proteins, among which tea polyphenol palmitate (TPP) + antioxidant of bamboo leaf (AOB) exhibited the best effect on improving overall quality of AKM. The color indicator (L*) was negatively correlated with hydrophilic pyrrole, hydrophobic pyrrole and lipid oxidation indexes, suggesting that Maillard-like reaction and lipid oxidation contributed to the color darkening. Furthermore, AK oil (AKO) extracted from the AKM treated with TPP + AOB showed lower initial oxidation level and better storage stability (peroxide value (POV): from 1.84 to 7.20 mg CHP/g, thiobarbituric acid reactive substances (TBARs): from 0.62 to 0.97 ppm) compared to that from the control AKM (POV: from 2.31 to 7.64 mg CHP/g, TBARs: from 0.68 to 1.04 ppm).

Dopamine (DA) has attracted attention because of its effects on Haematococcus lacustris biomass, astaxanthin production, and physiological responses. The alga treated with 25 μM DA combined with 1 g L –1 sodium chloride exhibited 7.63 %, 41.25 %, and 52.04 % increases in biomass (1.41 g L –1 ), astaxanthin content (32.37 mg/g), and astaxanthin productivity (3.51 mg L –1 d –1 ) respectively, compared with the salinity stress and high light. Exogenous DA treatment promoted lipid synthesis while reducing carbohydrate and protein contents. Moreover, carotenogenesis and lipogenesis-associated genes were upregulated under DA induction. Inhibition of reactive oxygen species and autophagy, along with mitogen-activated protein kinase activation, promoted astaxanthin accumulation under DA. Furthermore, DA application boosted astaxanthin biosynthesis by regulating the levels of respiratory metabolic intermediates, the γ-aminobutyric acid shunt, and important phytohormones. These findings present a potential and successful biotechnological approach for enhancing biomass and astaxanthin production in H. lacustris under stressful conditions.

The present study examined the outcomes of boiling (BO), air frying (AF), and boiling combined with air frying (BO-AF) methods on the appearance, texture, taste, and flavor of crayfish meat through a combination of sensory and instrumental analyses. The Free Choice Profiling and Check-All-That-Apply results showed that the BO-AF group had the highest overall acceptability. The BO-AF group presented an attractive golden color, crispy outside, and tender inside characteristics in appearance and texture. However, there was a loss of umami and sweetness in crayfish meat from the AF and BO-AF groups compared to the control (CK) and BO groups. Crayfish meat was identified as containing 42 volatile compounds. Among them, aldehydes and heterocyclic compounds were the main volatile compounds in the AF and BO-AF groups. In particular, the pyrazine compounds were produced by the thermal decomposition of methionine and cysteine. They gave the crayfish meat of the AF and BO-AF groups their characteristic roasted aroma and good color. However, compared to the AF group, the BO-AF group had the characteristic baking aroma of the AF group, as well as a floral and fruity aroma due to the presence of the boiling treatment.

Food freshness indication labels have a broad application prospect in the field of food safety because of monitoring the freshness of food and its environment in real time, which can assist consumers in identifying the freshness of food. Herein, large-area nanofiber films with colourimetric and fluorescent dual-channel indication were prepared via electrospinning technology using fluorescein isothiocyanate (FITC) with biogenic amine response as the indicator. FITC/PVA nanofiber films resulted in enhanced thermal stability and mechanical properties. With the increase of ammonia concentration in the atmosphere, the FITC/PVA composite films exhibited a gradual change in colour from grey to orange under daylight conditions. Furthermore, the green fluorescence was observed to gradually intensify under ultraviolet (UV) light. The results of shrimp freshness monitoring demonstrated obvious colour changes under both daylight and UV light condition, which the colour of the nanofiber films underwent a transformation from yellow to dark orange (ΔE = 46.18) under daylight and from green to bright yellow-green (ΔE = 41.77) under UV light after 1 day at 25 °C. The principal reason for the colour change of the films is the release of organic amine molecules during the spoilage process of fresh shrimp, leading the deprotonation of FITC under alkaline atmosphere and the change in its molecular conformation, resulting in the colour change and fluorescence enhancement of FITC under daylight. This colourimetric and fluorescent dual-channel response nanofiber films has the potential to be utilized in the field of food freshness monitoring to ensure the safety of the food supply.

The major component of theSolenocera crassicornishead protein hydrolysates-fraction 1 (SCHPs-F1) are low molecular weight peptides (MW < 1 kDa). In this study, we investigated the potential renoprotective effects of SCHPs-F1 in a cyclophosphamide (CTX) toxicity mouse model. In brief, 40 male mice were randomly divided into 5 groups and received either saline or 80 mg/kg body weight (BW) CTX by intraperitoneal injection for 5 days, followed by either saline or SCHPs-F1 (100, 200, and 400 mg/kg BW) by intragastric administration for 15 days. SCHPs-F1 treatment significantly reversed the CTX-induced decreases in the levels of blood urea nitrogen (BUN), creatinine (CRE), and cytochrome P450 (CYP450), as well as the renal histological lesions. Furthermore, the results indicated that SCHPs-F1 potentially alleviated CTX-induced nephrotoxicity through mitigating inflammatory responses, oxidative stress, and apoptosis status of the kidneys, as evidenced by decreased levels of malondialdehyde (MDA), interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ and increased levels of total antioxidant capacity (T-AOC), catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Moreover, overexpression of pro-apoptotic proteins pair B-cell lymphoma-2 (Bcl-2)-associated X (Bax)/Bcl-2, cysteinyl aspartate specific proteinase (caspase)-3 and caspase-9 in renal tissues were suppressed by treatment with SCHPs-F1. In addition, the protein levels of the antioxidant factor nuclear factor erythroid-2 related factor 2 (Nrf2) and the expression levels of its downstream target genes heme-oxygenase (HO-1), glutamate-cysteine ligase modifier subunit (GCLM) and NAD(P)H dehydrogenase (quinone) 1 (NQO-1) were stimulated by treatment with SCHPs-F1 in the CTX-induced renal injury model. Taken together, our data suggested that SCHPs-F1 could provide a novel potential strategy in mitigating the nephrotoxicity caused by CTX.Keywords:apoptosis;cyclophosphamide;inflammation;oxidative stress;peptides;Solenocera crassicornis

Organic acids acts as an growth promoter and antimicrobial agent in aquaculture. The present study investigated the effects of a natural organic acid - succinic acid (SA) on the growth, digestive enzymes , immune response and resistance to ammonia stress of Litopenaeus vannamei . The shrimps were firstly fed with diets containing different levels of SA: 0% (Control), 0.25% (SA1), 0.50% (SA2), and 1.0% (SA3) ( w / w ) for 56 days, followed by an acute ammonia stress for 48 h. The results indicated that dietary of SA improved the growth of shrimp, and increased the survival rate of shrimp after ammonia stress for 48 h. The amylase , lipase and pepsin activity increased in hepatopancreas in three SA group, while trypsin activity was only increased in the SA1 and SA2 groups. At 56 d, T-NOS activity, proPO and HSP70 gene expression level increased in the three SA group, PO activity increased in the SA1 and SA2 groups, T-AOC content and Toll gene expression level increased in the SA2 and SA3 groups, Trx and SOD gene expression level increased in the SA2 group, while Imd , GS and GDH gene expression level was no changes. After exposure to ammonia stress for 48 h, immune biochemical parameters (T-AOC and PO) and genes ( proPO , HSP70 , Trx and GDH ) expression level increased in the three SA group, T-NOS activity, Toll , Imd and GS gene expression level increased in the SA2 and SA3 groups, while SOD gene expression level increased in the SA1 and SA2 groups. These results indicated that SA improved growth, enhanced digestive and immune capacities of L. vannamei against ammonia stress, and may be a potential feed additive for shrimp. The optimal dietary supplementation dosage is 0.50% ( w / w ) in diet.

An 8-week feeding trial was conducted to evaluate the optimum dietary glycine level in low fishmeal diet for juvenile Pacific white shrimp , Litopenaeus vannamei . Six practical diets (44.4% protein, 8.8% lipid) were formulated to contain graded levels (2.26, 2.33, 2.44, 2.58, 2.67 and 2.74%) of l -glycine. Each diet was randomly assigned to triplicate groups of 30 shrimps (approximately 0.61 g) and the shrimps were fed 4 times a day to apparent satiation. The results indicated that the weight gain and specific growth rate were significantly increased with the supplementation of glycine. The highest weight gain and specific growth rate were observed at 2.56% dietary glycine, and then decrease with a further increase in dietary glycine. Hepatosomatic index , protein productive value and condition factor were also significantly influenced by the dietary glycine levels and show a similar trend to those of growth performance. There were no significant differences observed in feed efficiency , protein efficiency ratio and survival among all treatments. Mg, Ca and Fe concentrations in whole body were significantly increased with the supplementation of glycine. Non-essential amino acid, essential amino acid and arginine ratio in muscle were significantly affected by the dietary glycine levels. Dietary glycine levels higher than 2.44% significantly increased the survival of shrimps after 2 h and 3 h of acute salinity change, and T-SOD activity and Na + /K + -ATPase activity in hematological and hepatopancreas before and after acute salinity change are also significantly affected by the dietary glycine levels. Analysis by second-order regression of weight gain indicated that the optimal dietary glycine level was 2.54% of the dry diet (5.7% of the dietary protein and 6.66% of the dietary amino acids).

Astaxanthin , a pink/red pigmented keto carotenoid occurring in certain algae, is an anti-oxidant that protects the cell from damage by attenuating the reactive oxygen species due to which it has immense potential to protect the skin and other allied cells. Commercially available chemical UV-filters used in sunscreen creams and lotions are not only inadequate in protecting the skin against the harmful UV-rays but also cause skin damage like skin irritation , skin-aging, allergic reactions upon prolong exposure to these chemicals. Moreover, they cause environmental pollution and damage, mainly to aquatic life . So, natural compounds having similar or improved protective potential against UV irradiated skin are in dire need in the cosmetics industry. Recent studies substantiate that astaxanthin can be employed in sunscreens owing to its high antioxidant potential and significant use as an anti-aging, anti-inflammatory, and anti-cancer compound. Astaxanthin accumulation has been found in microalgae and its properties suggest that astaxanthin can provide total protection against all the UVR related skin problems starting from the acute effects of sunburn, pigmentation , erythema to chronic effects of inflammation, photoaging and skin cancer. In this paper, astaxanthin's importance, sources, chemical structure, pilot scale production and its potential applications in cosmetic industry have been discussed.

Bile acid metabolism in aquatic animals usually is suppressed when fish meal (FM) is replaced by plant proteins. An eight weeks feeding experiment was conducted to evaluate the effects of dietary chenodeoxycholic acid (CDCA) supplementation on growth, immune response and intestinal health of Penaeus monodon fed a low FM diet. Three diets were formulated: high FM (25 %) diet (HF), low FM (15 %) diet (LF), and low FM diet supplemented with 0.1 % CDCA (LFC). Shrimp fed Diet LF showed lower weight gain and feed efficiency than those fed Diet HF. Low dietary FM up-regulated the mRNA level of xbp1 , and down-regulated the mRNA levels of sod , iap and NF-κB signaling pathway-related genes ( traf6 , tube ). Dietary supplementation of CDCA up-regulated the expression of relish and anti-oxidative-related genes ( sod and cat ) in the hepatopancreas and midgut. Low dietary FM impaired the intestinal fold and induced the endoplasmic reticulum swollen of intestinal epithelial cell, dietary supplementation of CDCA alleviated this problem. The intestinal microbiota diversity was lower in shrimp fed Diet LF than those fed HF. Dietary supplementation of CDCA in a low FM diet increased the intestinal microbiota diversity by decreasing the relative abundance of dominant phylum Proteobacteria. Low dietary FM increased the relative abundance of a dominant pathogenic bacterium ( Vibrio ), which was decreased by the supplementation of CDCA. These results indicated that dietary supplementation of CDCA in a low FM diet improved the growth performance, immune response and intestinal health of shrimp.

As an ideal raw material for the production of astaxanthin, H . pluvialis was drawing attention during the last few years, there are some research topics initiated to find out the synthetic pathway of astaxanthin in H . pluvialis . In this study, confocal microscopic Raman technology was utilized to analyze the point-by-point mapping for H . pluvialis , and the visualization of pigment such as carotenoid and astaxanthin content were achieved. By comparing the Raman spectra of H . pluvialis and standard product of astaxanthin, and using the C = C stretching vibration of the Raman intensity as the main indicator for carotenoids, the visual spatial distribution for the carotenoids content was obtained. The MCR-ALS was applied to analyze the Raman data of H . pluvialis , and the information of astaxanthin was extracted to achieve real-time spatial distribution. The visualization of astaxanthin content shows that MCR-ALS is very effective for extracting the information of astaxanthin content from H . pluvialis . By exploring the spatial distribution of carotenoids and astaxanthin contents, analyzing the spatial distribution rules during its growth, Raman spectroscopy technology can be utilized to investigate the internal components of the pigment (ataxanthin, etc.) in H . pluvialis , which make it as an effective methodology to monitor the accumulation and changing mechanism of pigment content in microalgae.

Plastic and biomass waste are high quality carbon sources for carbon materials. Polyvinyl chloride (PVC) and shrimp shells were selected to investigate the synergistic conversion of co-hydrothermal carbonization and the electrochemical properties of carbon materials. It was found that the particle agglomeration of PVC plastics could be effectively avoided, thus, the dechlorination from UPVC tubes and shrimp shells at 220 °C for 120 min (HUPS 220–120) was up to 100.9 wt%, which was four times higher than solo hydrothermal treatment of UPVC tubes. The dissolution of calcium and magnesium in PVC plastics or shrimp shells was positively and linearly related to the removal of chloride ions on PVC plastics, with the molar ratio close to 1:2. The hydrolysis of shrimp shells catalyzed by hydrogen chloride (HCl), providing abundant nucleophilic groups, which in turn substituted for chlorine on PVC to form polyethers and polyamines. Interestingly, the co-hydrothermal treatment induced O and N functional groups on the hydrochars to maintain and evolve into C O and pyridinic-N after further carbonization and activation. With the features of large specific surface (1161.3 m 2 ·g −1 ), numerous microporous (87.66 %), high graphitization degree (I D /I G =0.85), and abundant C O and pyridinic-N, the carbon materials derived from hydrochar (CHPS 220–60) demonstrated strong charge storage capacity, good conductivity, and multiple redox potentials, raising the capacitive performance as high as 277.5 F·g −1 at 0.5 A·g −1 . This work aims to provide an effective method not only for the upcycling of PVC plastics and shrimp shells but also for the preparation of energy storage materials.

Peptides containing branched-chain amino acids (BCAAs) are recognized for their diverse physiological functions; however, effective methods for their target refinement remain underdeveloped. This study introduced a novel approach utilizing the cavity structure of cyclodextrins, along with specific adsorption (50 % ethanol, 50 °C) and crystallization conditions (75 % ethanol, 4 °C), to selectively isolate BCAA-containing oligopeptides from Antarctic krill. Following refinement, the relative BCAA content was elevated to 1.70-fold compared to the original peptide mixture, with the number and abundance of BCAA-containing peptides reaching 95.00 % and 94.96 %, respectively. Principal component and spectral analysis demonstrated that initial ethanol concentration and cyclodextrin cavity size significantly influenced the peptidome profiles by modulating peptide-cyclodextrin interactions. This study provides a comprehensive exploration of the molecular interactions between peptides and cyclodextrins, highlighting a novel application of cyclodextrins for target peptide isolation and offering deeper insights into the principles governing cyclodextrin inclusion.
