Food Technological Additives Characterization Service

Food Technological Additives Characterization Service

Food technological additives such as enzymes and fermentation agents play a critical role in food production. Aprofood has the expertise and state-of-the-art facilities fully equipped to provide industry-leading characterization services for food technological additives.

Why Characterization Services for Food Technological Additives?

Characterization services for food technological additives are a type of service used to identify and evaluate the type, activity, and effect of enzymes/fermentation agents in food products. These services are usually provided by our specialized laboratories to ensure that additives used in food production meet quality and safety requirements.

Our Service

Aprofood performs a variety of characterization tests on food technological additives, including species identification, stability testing, effect assessment, impurity detection, and more.

Species Identification

Identifying the specific types of enzymes and fermentation agents used in food products, such as amylases, yeast, probiotics, etc.

Identification of amylase

The maltose produced by the hydrolysis of starch by amylase can be determined with the 3,5-dinitrosalicylic acid reagent. The identification of amylase is accomplished by measuring the absorbance with a spectrophotometer using maltose as the standard.

Identification of yeast

Saccharomyces cerevisiae is mainly known for its capacity to produce sugars like glucose, fructose, sucrose and maltose. Yeast can be identified by sugar fermentation test, carbon assimilation test and nitrogen assimilation test.

Identification of probiotics

Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), whole genome sequencing, and real-time fluorescence quantitative polymerase chain reaction (RT-FQ-PCR) enable the identification of probiotics at the subspecies and strain level.

Effectiveness Assessment

Aprofood performs laboratory tests on food samples to evaluate the role and effect of enzymes/fermentation agents in food products.

  • Fermentation Performance Test
    By assessing the physical attributes of fermented dough, such as its softness, hardness, ductility, and viscosity, valuable qualitative data can be obtained to aid in the research and optimization of its formulation and processing.
  • Food Stability Test
    Once food technological additives have been incorporated, it is essential to assess the durability of food products by assessing their resistance to high temperatures, antibacterial, antioxidant, etc.

Impurity Detection

Impurity testing of enzymes/fermentation agents is an important step in ensuring product quality and safety. Aprofood offers testing for the following impurities.

Impurities in raw materials

Microorganisms impurities

Non-specific impurities

Characterization Methods for Food Technological Additives

Aprofood characterizes additives using a variety of analytical methods, including but not limited to the followings.

High-performance Liquid Chromatography (HPLC) Infrared Spectroscopy (IR) Ultraviolet-visible Spectroscopy (UV-Vis)
HPLC is a convenient, rapid and accurate method for the detection of food technological additives, and is used for the simultaneous detection. Characteristic peaks of additives are uniquely identified in specific regions of the infrared spectrum, leading to quantitative analytical conclusions. UV-Vis is capable of measuring and analyzing the intrinsic composition of foodstuffs to detect whether they have been produced in compliance with hygienic norms.

In addition, we can offer other types of analytical techniques for characterization, e.g. particle sizing and imaging instruments.
