Special Issue Information

Dear Colleagues,

Biochemical analysis and determination methods have always been important tools and key instruments for ensuring food safety, quality and nutritional value. Biochemical analysis of food, as a discipline that combines food science and chemistry, can be used to determine (identify, quantify and characterize) all types of components in foods, including nutrients, contaminant residues and additives, etc. The field of biochemical analysis and detection of food has made significant advances in recent decades, developing new methods and techniques to meet the challenges of sensitivity, accuracy and cost-effectiveness.

  • Characterization and analysis of food components and nutrients. This includes the identification and quantification of nutrients (proteins, carbohydrates and fats/fatty acids) and micronutrients (vitamins and minerals), among others;
  • Detection and quantification of food safety and contamination residues. This includes the detection of harmful substances such as pathogenic micro-organisms, pesticides, chemical residues, antibiotics, heavy metals and plasticizers, as well as the identification of potential allergens, disease-causing agents and toxins;
  • Assurance and monitoring of food quality and preservation. This includes determination of nutrient components, pH and spoilage/microbial growth, analysis of flavor compounds and monitoring of reactions to chemicals (e.g., enzymes and antioxidants, etc.) during processing, as well as monitoring the effectiveness of preservation techniques such as irradiation and pasteurization;
  • The regulatory and traceability analysis of food fraud and food authenticity. This includes identification of adulteration, the determination of geographical indications, traceability, and analysis of chemical markers;
  • Breakthroughs in food biochemical detection/analytical technologies. This includes non-invasive techniques such as Raman/infrared spectroscopy, characterization of ingredients such as (bio)sensors, high-throughput analysis such as liquid/gas chromatography–mass spectrometry, and chemometric methods for food histology.

In this Special Issue entitled "Recent Research and Applications of Biochemical Determination and Analytical Techniques in Food", we warmly welcome all experts and researchers in the field to submit scientific articles related to the above, aiming at expanding the multifaceted understanding of food products with advanced and multifaceted biochemical analytical techniques, while also providing a broad platform for the exchange of your research results.

Astringency has an important impact on the taste quality of tea infusion, a process which occurs when polyphenols complex with salivary proteins to form an impermeable membrane. (-)-Epigallocatechin gallate (EGCG) is the main astringent compound found in green tea and mucin is the main protein present in saliva. Determining the turbidity of EGCG–mucin mixtures is an effective method to quantify the astringency intensity of EGCG solutions. In this study, the effects of taste-related, substances present during green tea infusion, on the turbidity of EGCG–mucin mixtures was investigated under the reacting conditions of a pH value of 5.0, at 37 °C, and for 30 min. The results showed that epicatechins, caffeic acid, chlorogenic acid, and gallic acid reduced the turbidity of EGCG–mucin mixtures, while rutin increased turbidity. Metal ions increased the turbidity of EGCG–mucin mixtures. These can be arranged by effectiveness as Al3+ > K+ > Mg2+ > Ca2+. Caffeine, theanine, and sodium glutamate all decreased the turbidity values of EGCG–mucin mixtures, but sucrose had a weak effect. Further experiments confirmed that the turbidity of green tea infusion–mucin mixture indicated the astringent intensity of green tea infusion, and that the turbidity was significantly correlated with the contents of tea polyphenols and EGCG.
