The dairy industry is a significant player in the food industry, providing essential products such as milk, cheese, butter, yogurt, and milk powder to meet the global population's needs. However, the industry's activities have resulted in significant pollution, with heavy waste generation, disposal, and effluent emissions into the environment. Properly handling dairy waste residues is a major challenge, with up to 60% of the total treatment cost in the processing unit allocated to waste management. Therefore, valorizing dairy waste into useful products presents a significant advantage for the dairy industry. Numerous studies have proposed various approaches to convert dairy waste into useful products, including thermochemical, biological, and integrated conversion pathways. This review presents an overview of these approaches and identifies the best possible method for valorizing dairy waste and by-products. The research presents up-to-date information on the recovery of value-added products from dairy waste, such as biogas, biofertilizers, biopolymers, and biosurfactants, with a focus on integrating technology for environmental sustainability. Furthermore, the obstacles and prospects in dairy waste valorization have been presented. This review is a valuable resource for developing and deploying dairy waste valorization technologies, and it also presents research opportunities in this field.

This study focused on developing an innovative cooking technique for camel meat by integrating ohmic heating with sous vide (SV) cooking. The newly developed ohmic-sous vide (OSV) system, featuring automated temperature control and SV pouches, was evaluated against the conventional SV method. Performance was assessed based on energy parameters and thermophysical characteristics at various cooking temperatures (70°C, 80°C, and 90°C) and durations (30, 60, 90, and 120 min). The results demonstrated that the OSV system required significantly less energy and preheating time compared to the traditional SV method, achieving superior energy efficiency. While final meat yields were comparable between the two methods, energy efficiency for OSV cooking reached 80.3% at 70°C after 30 min, compared to 58.36% for the SV method. At 80°C, the energy efficiencies were 75.77% for OSV cooking compared to 51.19% for SV, and at 90°C, they were 70.97% versus 44.30%, respectively. Additionally, thermophysical properties of camel meat, including thermal conductivity, thermal diffusivity, specific heat, density, and cooking yield, showed significant decreases as cooking temperature and time increased for both cooking methods. Notably, camel meat prepared using OSV exhibited lower thermal conductivity and density than that cooked with SV, reflecting structural changes that may enhance tenderness and juiciness. These findings suggest that the integrated OSV technique offers promising energy efficiency benefits in the culinary meat industry, highlighting the need for further research into its broader applications and advantages.

Triticum dicoccum (Farro) an ancient wheat species has recently gained attention for its exceptional health benefits. However, research on its antibacterial and anti-biofilm properties remains limited. Additionally, a growing trend has been observed in releasing enriched or fortified whey beverages to enhance their functionality. Therefore, this study aimed to investigate the inhibitory effects of whey beverages supplemented with enzyme-rich fermented farro (WF) on Salmonella Typhimurium biofilm formation and explore the underlying mechanisms. Treatment with WF significantly reduced biofilm formation and viability of S. Typhimurium. Moreover, WF decreased the bacterial adhesion to and invasion of human intestinal epithelial cells. WF also inhibited gene expression associated with motility and initial adhesion in S. Typhimurium, as well as genes involved in quorum sensing (QS), in a concentration-dependent manner. Furthermore, WF suppressed the production of the QS signaling molecule autoinducer-2 in a similar concentration-dependent manner. Consequently, our findings indicate that the addition of enzyme-rich fermented farro to whey beverage enhances anti-biofilm activity, which is probably attributed to its antimicrobial effects, inhibition of initial adhesion, and QS reduction. These findings offer a promising basis for developing fortified dairy beverages that can enhance food safety and promote human health.

Triticum dicoccum(法罗麦)是一种古老的小麦品种,最近因其卓越的保健功效而备受关注。然而,对其抗菌和抗生物膜特性的研究仍然有限。此外,为了增强乳清饮料的功能,人们越来越倾向于推出富含乳清或强化乳清的饮料。因此,本研究旨在调查富含酶发酵远志(WF)的乳清饮料对鼠伤寒沙门氏菌生物膜形成的抑制作用,并探索其潜在机制。经 WF 处理后,鼠伤寒沙门氏菌生物膜的形成和存活率明显降低。此外,WF 还能减少细菌对人体肠道上皮细胞的粘附和侵袭。WF 还能以浓度依赖性方式抑制伤寒杆菌与运动和初始粘附相关的基因表达,以及与法定量感应(QS)相关的基因表达。此外,WF 还以类似的浓度依赖性方式抑制了 QS 信号分子自动诱导因子-2 的产生。因此,我们的研究结果表明,在乳清饮料中添加富含酶的发酵远红外能增强抗生物膜活性,这可能归因于其抗菌效果、抑制初始粘附和减少 QS。这些发现为开发强化乳制品饮料提供了一个很好的基础,可以提高食品安全,促进人类健康。

This study evaluated the suitability of black goat meat as a raw material for meat products by comparing the physicochemical and storage characteristics of emulsified sausages from different livestock species: black goat sausage (GS), beef sausage (BS), pork sausage (PS), and chicken sausage (CS). GS and PS showed similar proximate composition, while GS and BS had comparable values for CIE L*, CIE b*, and hue angle, indicating potential consumer appeal. Water-holding capacity (WHC) and cooking yield showed no significant differences between GS, BS, and PS, highlighting black goat's ability to retain moisture. GS and CS showed significantly higher pH value than that of the other samples (p<0.05). The thiobarbituric acid reactive substance (TBARS) values, indicating lipid oxidation, were significantly lower in GS and PS (p<0.05), showing that GS resists oxidation well, with a strong correlation to fat content (r2=0.95). By the 3rd and 4th wk of storage, GS and CS had higher the volatile basic nitrogen values (p<0.05), correlating with pH (r2=0.83), while bacterial counts in GS, BS, and PS remained below 7 Log CFU/mg for up to 5 wk. GS's high WHC, cooking yield, and low TBARS values suggest good commercial potential.

The bone is an important body organ due to its role in locomotion, protection and mineral homeostasis. Bone health is affected by various intrinsic and extrinsic factors like genetics, diet, environment and immune status of an individual. Being a dynamic organ, bones are continuously being remodeled and the remodeling is mediated by an intricate balance of bone formation and resorption which, in turn, are regulated by environmental, genetic, hormonal and neural factors. Lack of balance in any of these factors leads to bone disorders such as osteoporosis. Fermented dairy products along with their probiotics content play a significant role in bone remodeling process ensuring the maintenance of intricate balance in bone forming cells (osteoblasts) and bone resorbing cells (osteoclasts). Proteins and various minerals are important constituents of bone. Dairy products, especially fermented ones, are significant because of being a good source of proteins and minerals required to make and maintain a healthy bone. In addition, these provide the body with probiotics which are involved in bone health improvement by enhancing the bioavailability of dietary constituents, production of short chain fatty acids and reducing the inflammatory components. Hence, fermented dairy products should be a regular part of our diet to keep our bone healthy.

Bile salt hydrolase (BSH: EC.3.5.1.24) has been used as a biomarker for probiotics for an extended period. It is mostly present in the gut environment of vertebrates. Additionally, it influences the viability of probiotics. This biomarker is considered a promising nutritional supplement due to its unique ability to effectively address elevated blood cholesterol levels, a common issue in modern society. However, the commercialization of BSH has been limited by an incomplete understanding of the intestinal microbiota and the function of BSH. Hence, in this review, we aim to reveal the current advancements in BSH research and outline the necessary areas of investigation for future studies. The review highlights key findings related to the substrate affinity of BSH in probiotic bacteria and its BSH gene phylogeny that have been researched until today, suggesting further research regarding the differences in multiple BSH genes and corresponding differences in BSH affinity.

胆盐水解酶(BSH:EC.3.5.1.24)长期以来一直被用作益生菌的生物标志物。它主要存在于脊椎动物的肠道环境中。此外,它还会影响益生菌的活力。这种生物标志物被认为是一种很有前景的营养补充剂,因为它具有有效解决血液胆固醇水平升高这一现代社会常见问题的独特能力。然而,由于对肠道微生物群和 BSH 功能的了解不全面,BSH 的商业化一直受到限制。因此,在本综述中,我们旨在揭示目前 BSH 研究的进展,并概述未来研究的必要调查领域。综述重点介绍了益生菌中 BSH 的底物亲和力及其 BSH 基因系统发育的相关研究成果,并建议进一步研究多个 BSH 基因的差异以及 BSH 亲和力的相应差异。

Pork belly is one of the most valuable primal cuts of pork with high preferences. Although meat quality is becoming increasingly important, defining pork belly quality is challenging owing to the structure and diversity of the preferred characteristics. This study identified the factors influencing pork belly quality traits through a literature review. In total, 55 articles related to pork belly quality were selected and summarized. The quality traits of pork belly are considered to be various factors, including belly yield (weight, length, thickness, etc.), firmness, fatty acid composition, color, and sensory properties. The quality of pork belly is influenced by various factors, such as sex, genetic parameters, carcass weight, and diet. A more diverse approach is required to comprehensively understand the quality traits and impact factors of pork bellies.

Overcrowding stress in livestock farming is a significant concern for animal health and livestock products such as meats, milk, and eggs. It affects gut health by altering microbiota and regulating neuronal nitric oxide synthase (nNOS). This study aimed to investigate the effects of overcrowding stress on the gut microbiota composition and nNOS expression. We generated an nNOS-HiBiT knock-in mouse model using the HiBiT system, a highly sensitive tool for accurately quantifying gene expression. Overcrowding stress was induced by housing twenty mice per cage (MPC20) and compared with a control group of two mice per cage (MPC2). Overcrowding stress increases nNOS levels in the hypothalamus and ileum and serum corticosterone levels. Gut microbial composition differed between the control and overcrowding stress-induced groups in the ileum, cecum, and colon. Specifically, Bifidobacterium and Akkermansia decreased in all three regions of MPC20, whereas Helicobacter in the ileum and colon and Parasuterella in the cecum increased in MPC20. Notably, Bifidobacterium consistently decreased when nNOS and corticosterone expression were used as covariates under overcrowding stress. These regional variations reflect the differential impact of overcrowding stress on the intestinal tract, indicating complex interactions through nNOS expression within the brain-gut-microbiome axis. Importantly, the addition of probiotic feed, particularly those containing Bifidobacterium, may counteract these decreases, leading to enhanced gut health and improved quality of livestock food products. This study enhances our understanding of the correlation between overcrowding stress and the gut microbiota, providing valuable data for improving the management environment in livestock farming.

畜牧业中的过度拥挤压力是动物健康和肉类、牛奶和鸡蛋等畜产品的一个重大问题。它通过改变微生物群和调节神经元一氧化氮合酶(nNOS)来影响肠道健康。本研究旨在调查过度拥挤应激对肠道微生物群组成和 nNOS 表达的影响。我们利用高灵敏度的基因表达量化工具 HiBiT 系统建立了一个 nNOS-HiBiT 基因敲入小鼠模型。每个笼子饲养二十只小鼠(MPC20),诱发过度拥挤应激,并与每个笼子饲养两只小鼠(MPC2)的对照组进行比较。过度拥挤应激会增加下丘脑和回肠中的 nNOS 水平以及血清皮质酮水平。对照组和过度拥挤应激诱导组小鼠回肠、盲肠和结肠中的肠道微生物组成存在差异。具体来说,双歧杆菌和Akkermansia在MPC20的所有三个区域都减少了,而回肠和结肠中的螺旋杆菌以及盲肠中的伞菌在MPC20中增加了。值得注意的是,在过度拥挤压力下,当使用 nNOS 和皮质酮表达作为协变量时,双歧杆菌持续减少。这些区域性差异反映了过度拥挤应激对肠道的不同影响,表明在大脑-肠道-微生物组轴中通过 nNOS 的表达产生了复杂的相互作用。重要的是,添加益生菌饲料,尤其是含有双歧杆菌的益生菌饲料,可能会抵消这些下降,从而增强肠道健康,提高牲畜食品的质量。这项研究加深了我们对过度拥挤压力与肠道微生物群之间相关性的理解,为改善畜牧业的管理环境提供了宝贵的数据。

It affects gut health by altering microbiota and regulating neuronal nitric oxide synthase (nNOS). This study aimed to investigate the effects of overcrowding stress on the gut microbiota composition and nNOS expression. We generated an nNOS-HiBiT knock-in mouse model using the HiBiT system, a highly sensitive tool for accurately quantifying gene expression. Overcrowding stress was induced by housing twenty mice per cage (MPC20) and compared with a control group of two mice per cage (MPC2). Overcrowding stress increases nNOS levels in the hypothalamus and ileum and serum corticosterone levels. Gut microbial composition differed between the control and overcrowding stress-induced groups in the ileum, cecum, and colon. Specifically, <i>Bifidobacterium</i> and <i>Akkermansia</i> decreased in all three regions of MPC20, whereas <i>Helicobacter</i> in the ileum and colon and <i>Parasuterella</i> in the cecum increased in MPC20. Notably, <i>Bifidobacterium</i> consistently decreased when nNOS and corticosterone expression were used as covariates under overcrowding stress. These regional variations reflect the differential impact of overcrowding stress on the intestinal tract, indicating complex interactions through nNOS expression within the brain-gut-microbiome axis.

The Korean native black goat (Capra hircus coreanae, KNBG) is an indigenous breed of Korea, consisting of three registered strains: Jangsu, Tongyeong, and Dangjin. KNBG meat is highly valued for its health benefits, including low levels of saturated fat and cholesterol, along with high levels of protein, calcium, and iron. It is a rich source of essential amino acids and other bioactive compounds, including L-carnitine, creatine, creatinine, carnosine, and anserine, which contribute significantly to maintaining good health. The increasing popularity of KNBG meat has expanded its culinary applications, including its use in various traditional dishes. Herbs and spices are often employed to further mitigate its distinct aroma and increase consumer appeal. This review highlights the distinctive attributes of KNBG, focusing on its nutritional composition, bioactive compounds, and meat quality. It underscores its potential as a health-promoting food source and explores innovative pathways for product development to address market challenges. Further research is needed to clarify KNBG's health impacts, ensure the authenticity and integrity of goat meat considering regulatory shifts, and optimize its role as a sustainable, health-promoting food for domestic and global markets.

This study compared the physicochemical, sensory, and flavor-related properties of breast from two Korean native chicken (KNC) breeds, Woorimatdag No. 1 (WRMD1) and Woorimatdag No. 2 (WRMD2), to those of broilers, under fresh and various freeze-thaw treatments. WRMD1 generally exhibited the highest shear force value among the breeds, indicating tougher meat. The total aerobic bacteria count was significantly lower (p<0.05) in broiler meat compared to WRMD1 and WRMD2. The appearance perception on the sensory evaluation of fresh WRMD1 meat was significantly lower than that of broiler meat (p<0.05). The chicken breed influenced the fatty acid profile. The KNC breeds exhibited higher levels of essential and taste-related fatty acids compared to the broilers. Notably, WRMD1 exhibited the highest inosine monophosphate concentration, a key nucleotide responsible for umami taste. The freeze-thaw treatment did not significantly influence the fatty acid profile. Several volatile organic compounds such as (S)-(+)-3-methyl-1-pentanol, propanal, 2-methyl-, sec-butylamine, 3,3-dimethyl-1,2-epoxybutane, hexanal, 5-methyl-, 1-octen-3-ol, and 5-ethylcyclopent-1-enecarboxaldehyde were identified as potential markers for differentiating broiler and KNC meat. Overall, the breed had a more significant impact on the physicochemical and flavor characteristics of the meat, while quick freezing effectively preserved its fresh quality.
