Milk Quality Analysis
Milk and related products play a crucial role in providing a variety of nutrients and immunity for young mammals, and they are an important component in human diets as well. However, risks such as poor health conditions of milk-producing animals, environmental contaminants, and adulteration can compromise the quality of milk and dairy products, posing great health risks to humans. BioVenic uses a wide range of test methods to develop solutions for milk quality analysis. These solutions evaluate the nutrient content, chemical contaminants, microorganisms, bioactive components, and more in milk and dairy products. Additionally, we have the capability to develop novel assays for dairy quality-related parameters, enhancing the monitoring of milk and dairy quality.
Milk Quality Analysis for Different Animal Species
Milk varies greatly in appearance, nutritional content, and flavor depending on the animal source. Our milk quality testing solutions are tailored to the specific characteristics of milk from various animals, including cows, goats, sheep, buffaloes and more.
- Cow Milk
Whole cow's milk is approximately 87% water, with the remaining 13% comprised of protein, fat, carbohydrates, minerals and vitamins. It is one of the most widely consumed types of milk by humans.
- Goat Milk
Goat milk proteins contain lower levels of α-s1-casein, the protein responsible for most allergic reactions to cow's milk. Goat milk can also help reduce cholesterol levels in individuals with high blood cholesterol.
- Sheep Milk
Sheep milk is a rich source of biologically active proteins and nutrients, richer than cow's milk. While it is rarely consumed as liquid milk, sheep's milk is primarily used for cheese production and, in some countries, for making yogurt or whey cheeses.
- Water Buffalo Milk
Originating from the Indian subcontinent and Southeast Asia, domestic water buffalo milk has unique physicochemical features compared to other ruminant species, including higher fatty acid and protein content.
Milk Nutritional Analysis
Milk is rich in various nutrients, such as protein, carbohydrates, fat, calcium, iron, vitamins, and phosphorus. These nutrient compositions can vary significantly across different types of milk and related products. At BioVenic, we utilize advanced testing and analyzing instruments and reagents to provide comprehensive testing services for conventional nutritional components, bioactive proteins, enzymes, vitamins, and more in dairy products. Our representative testing items include:
- Conventional Nutritional Components: Protein, milk fat, lactose, moisture, fiber, etc.
- Enzymes: Lactoperoxidase, xanthine oxidase, alkaline phosphatase, lipase, protease, etc.
- Hormones and Growth Factors: Gonadal hormones (estrogens, progesterone), brain-gut hormones (GnRH, somatostatin, GH-releasing hormone, etc), calcitonin, thyroid gland hormones, TSH, erythropoietin, insulin-like growth factors, IGF binding proteins, EGF and transforming growth factor, insulin, relaxin, PRL, etc.
- Fatty Acids: Short-chain fatty acids, medium-chain fatty acids, unsaturated fatty acids, etc.
- Minerals: Calcium, iron, etc.
- Vitamins: Vitamin D, vitamin A, vitamin K, vitamin B12, riboflavin, niacin, etc.
Our sophisticated testing services ensure accurate and detailed nutritional analysis, enabling superior quality control and optimization of milk products.
Animal-Derived Component Detection in Milk
Dairy products originating from different animals show significant variations in nutritional content and market value. Current methods for detecting animal-derived components in milk and dairy products include molecular biology techniques (such as polymerase chain reaction (PCR) and real-time quantitative PCR) and protein detection methods. Our animal-derived ingredient testing solutions enable the identification of the origin of ingredients in milk and related products and aid in developing new assays to enhance detection effectiveness, potentially identifying adulteration in niche milk and dairy products.
Omics Solution for Milk Quality Analysis
Our omics solutions integrate advanced technology platforms, including genomics, proteomics, microbiomics, and metabolomics. These platforms enable high-throughput omics research on milk and dairy products and provide one-stop analysis solutions for omics study results.
- Proteomics of Milk and Milk Products
Using omics technology to study the composition, quantity, expression differences, and changes in milk proteins across various types and quality of milk, as well as different processing and storage methods, plays a crucial role in controlling high-quality milk sources, improving the development and utilization rates of milk products, and monitoring their quality. Our proteomics platform allows researchers to detect proteins such as milk fat globulin membrane, whey protein, and bioactive peptides in milk.
- Milk and Milk Products Metabolomics
The field of milk and dairy metabolomics offers a thorough approach to understanding animal health and the quality and safety of animal products. Common techniques used in metabolomic research include GC-MS, LC-MS, and HPLC-NMR. These state-of-the-art technologies detect organic acids, amino acids, sugars, aromatic amines, and fatty acids in milk and dairy products. Additionally, metabolomics techniques can identify small molecule biomarkers associated with milk quality, nutrition, and disease in milk-producing animals, as well as study changes in metabolites during the processing or storage of milk products.
- Milk and Milk Products Microbiome
Through sequencing the microbial genes in milk and dairy products, researchers can gain insights into the composition, diversity, and functions of beneficial or harmful bacteria present. This information enhances the safety of milk products and supports the development of potential probiotics.
Milk Safety Analysis
During the production and processing of dairy products, numerous factors influence their safety and quality. The primary factors and related dairy indicators include:
- Health Status of Dairy Animals: Somatic cell count (SCC) and electrical conductivity of milk (ECM) are indicators of the mammary gland's health status.
- Chemical Contaminants: These include pesticides, veterinary drugs, mycotoxins, heavy metals, etc.
- Adulterants: Such as melamine, preservatives, and other substances that might be added improperly.
- Biological Contaminants: Including Escherichia coli, Brucella spp., Streptococcus faecalis, etc.
To ensure milk quality and mitigate the threats to animal and human health posed by these safety issues, we offer comprehensive testing services for these critical indicators affecting milk safety. For specific dairy product safety indicators, we also provide assay development services to facilitate rapid and accurate testing.
