Traceability Report

In order to build consumers’ trust on the food market and the manufacturers of food products, it is essential that the chain of production from the acquisition of raw materials all the way till the end product is both transparent and systematic. Besides providing safety for consumers, cues indicating product origin, and the comprehensive traceability of raw materials, tell about product quality and, furthermore, could allow producers to sell their products at a premium price.

In order to prevent the jeopardization of the internal markets in food and feed, the EU has set laws for product traceability. However, the legislation is not very strict and definitive when it comes to describing what are the relevant properties to trace and how traceability might be implemented in practice. The aim of this study was to collect information on how raw material traceability works in practice with NTFPs, especially in their early stages of production, i.e. raw material acquisition.

Information was collected from a total of 19 companies in Finland, Latvia, Lithuania, and Norway, and based on the results, raw materials are traceable through the different stages of production as is required by the EU legislation. However, the ability to trace materials back to their origins varies from exact location to origin on country level. Nevertheless, based on this study, it is possible to acquire products with raw material traceability to exact origins. This information can be used in, for example, the development of authentication methodology, or in other scientific research where product origin needs to be known. In addition, this information can be provided to the customers if requested.

The determination of the authenticity of frozen and lyophilized bilberries and lingonberries of different regions in Lithuania, Latvia, Finland and Norway by Surface enhanced Raman spectroscopy (SERS)

 

Raman spectroscopy is a non-sensitive technique due to a weak scattering related to that only one of a million photons are scattered in-elastically. Therefore, low-intensity Raman bands are observed in the spectrum, what makes an analysis of a test object to be complicated. Especially in the cases, when the concentrations of the particular molecules of interest are extremely low. Moreover, when analyzing materials containing pigments, there is a probability that the fluorescent background will be observed in the spectrum, which interferes with the qualitative, as well as quantitative analysis of the test object. Since the bilberries and lingonberries are rich in anthocyanin, the main peaks of the bilberries expressed in the spectra are related to the vibrations of these organic compounds.

O4.3 Berry lipid quality and authentication results obtained from bilberries and lingonberries picked 2019 and 2020 from several regions

 

 

Forest berries and their products are gaining expanded popularity due to their better taste, natural origin, and health benefits. However, there is widespread lying about the origin of these berries in recent years so that lower-quality berries can be sold at a higher price. A specific focus was to identify lingonberry (Vaccinium vitis-idaea) and bilberry (Vaccinium myrtillus L.) samples from 4 different countries in a two-year period. To establish an accurate method for identifying the origin country of the berries by their lipid composition, the gas chromatography-mass spectrometry (GC-MS) approach was adopted. The used method may authenticate the lipid origin of blueberries due to a good correlation between the growth site and the years.

 Due to its numerous health-promoting characteristics, Vaccinium berries have grown in popularity among consumers and manufacturers. Wild bilberries and lingonberries are highly valued components in food and nutraceutical products. In the last 10 years, consumers have rekindled their interest in foodstuffs that are closely linked to a certain geographic location. As a result, there are an increasing number of items on the market bearing regional indications. As a result, determining the provenance of a product has become increasingly important. Adulteration is unfortunately a big global problem, therefore mislabeled and adulterated bilberry and lingonberry goods can also be found on the market. In order to safeguard consumers and avoid unfair competition, it is necessary to identify bilberry and lingonberries species throughout the whole manufacturing process, from the raw material level through the verification of labeling claims. Adulteration using replacements such as synthetic chemicals or cheaper berries, dilution, and mislabeling regarding botanical or geographical origin are all common ways of adulteration. In the instance of a mislabeled origin, a phytochemical analysis might be a useful and alternative technique in the authentication process. Bilberries and lingonberries, on the other hand, have a high concentration of anthocyanins, which are likely the most active components. There are substantial financial incentives to sell or create polluted raw materials or products due to today's intense competition. Because each genus' berries have their own unique anthocyanin composition, anthocyanin fingerprinting has been effectively utilized in quality control. Each of three sugar moieties (galactose, glucose, and arabinose) is bound to five aglycones (delphinidin, cyanidin, petunidin, peonidin and malvidin) in the blueberry anthocyanin profile, which includes 15 main characteristic anthocyanidin glycosides.
