Chenopodium quinoa

Inquiry

Chenopodium quinoa (quinoa) is an annual dicotyledonous herb in the genus Chenopodium of the Amaranthaceae. Quinoa is characterized by strong resistance to adversity, stress, comprehensive nutrient composition, and significant health effects. It is rich in pharmacologically active secondary metabolites, mainly polyphenols, flavonoids, and saponins, applied in food, cosmetics, pharmaceuticals, and other fields. Lifeasible can provide you with quinoa active ingredient extraction and analysis services, including proteins, flavonoids, saponins, etc., according to the test for quinoa's nutritional composition analysis and quality comprehensive evaluation.

What We Offer

Protein extraction and protein modification services

Quinoa has a higher protein content than barley, rice, corn, and wheat. We can provide alkaline extraction and acid precipitation methods, salt solubilization methods, and enzyme-assisted extraction methods. Moreover, we can analyze the effects of material/liquid ratio, ultrasonic power, ultrasonic time, extraction temperature, extraction time, and pH on the quinoa protein extraction rate by one-way test and optimize your existing quinoa protein extraction process by combining with response surface methodology (RSM).
Protein modification is an important method to improve the functional properties of proteins; we provide you with physical and enzymatic modification methods. Through appropriate modification, we can improve the functional properties of quinoa protein and help you expand the application of quinoa protein in food.

Saponin analysis services

We provide the means to extract quinoa saponins based on techniques such as complex enzymatic ultrasonic extraction and microwave-assisted supercritical extraction. We also support you in identifying single or multiple saponins using HPLC, MS, and NMR. In addition, based on GC-MS, NMR, and UV detection platforms, we can also be used for the rapid identification of more than a hundred endogenous small molecules and analyzing the specific substances that produce the bitter taste of quinoa.
On this basis, we can also analyze the metabolic changes of different metabolites of relevant biosynthetic pathways in quinoa by modern analytical tools such as non-targeted metabolomics, targeted metabolomics, and transcriptomics to better support your research on mining key genes of saponin biosynthetic pathways.

Flavonoid extraction and analysis services

We provide basic solvent extraction, microwave-assisted extraction, and ultrasound-assisted extraction of quinoa flavonoids. In addition, to further improve the extraction efficiency of quinoa flavonoids and minimize the loss of its active components, we also provide ultrasound-assisted extraction methods based on the addition of negative pressure to explore different ultrasound times, solid-liquid ratio and negative pressure on the extraction rate of quinoa flavonoids. The optimal process conditions for ultrasound-negative pressure-assisted extraction of quinoa flavonoids were obtained by RSM optimization.

Nutrient composition analysis and comprehensive quality evaluation services

Quality analysis and evaluation are the keys to clarifying the nutritional composition and application direction of grain resources. We can systematically analyze basic nutrients, amino acids, minerals, fatty acids, phenolic substances, and antioxidant activity, evaluate the quality of amino acids and fatty acids, and finally conduct a comprehensive evaluation of the nutritional characteristics of different quinoa varieties based on principal component analysis.

Physicochemical index determination	Ash, crude fat, protein, crude fiber, amino acids, fatty acids, minerals, total starch content, and straight chain starch content.
Amino acid evaluation	Total amino acid content (TAA) Essential amino acid (EAA) Non-essential amino acid content (NEAA) Essential amino acid/total amino acid (EAA/TAA) Ratio coefficient of amino acid (RC) Score of RC (SRC) Amino acid score (AAS) Essential amino acid index (EAAI) Biological value (BV) Nutritional index (NI)
Fatty acid evaluation	We can calculate the dietary ratio of Omega-6/Omega-3 series fatty acids and the fatty acid effect on atherogenic index (AI) and thrombogenic index (TI) based on the composition and content of fatty acids detected.

Compared to other traditional food crops, quinoa is characterized by its high nutritional value, high biological yield, and wide biological adaptability. Lifeasible will help you to develop the potential of quinoa in the areas of food and health care, drug research and development, agricultural economy, etc., from the aspect of combining scientific research and products so that it can obtain a broader space for development, and better demonstrate the value of research and application.
