Tsb medium preparation9/1/2023 ![]() Fruits of the species are small, about 2 cm long, red-orange ellipsoids with a sweet-tangy taste. barbarum is native to an area from south-eastern Europe to southwest Asia and was introduced to Europe in the 18th century. One way to enrich the diet with polyphenols is to use goji berries as food ingredients. The antibacterial effect of polyphenols is mainly associated with interactions with bacterial cell wall and cytoplasm membranes, leading to structural disorder of the cell and evoking cytoplasm leakage. ![]() The antioxidant activity of flavonoids is mainly attributed to its ability to facilitating the chelating of metal ions. Polyphenols’ anti-angiogenic and anti-inflammatory activity and deoxyribonucleic acid protection from ROS may result in ceasing the progression of tumors and triggering of apoptosis in tumor cells. The role of polyphenols in the removal of oxygen and reactive oxygen species (ROS) is also underlined with their implications for cell proliferation and modulation of specific proteins. Polyphenols are also recognised as factors promoting the immune system, offering protection from UV radiation, and stimulating antimicrobial action. A diet rich in polyphenols is recommended for the prevention of many diseases, e.g., cardiovascular and neurodegenerative diseases, cancer, and diabetes. Goji berries are rich resources of polyphenolic compounds, with the most numerous flavonoids, and above all flavonols, including kaempferol, myricetin, and quercetin. Moreover, they are characterized by antioxidant, immunostimulating, anticancer, and anti-atherosclerotic effects. barbarum are a rich reservoir of nutrients and are proven to be protective against retinal disorders, expressing a hypoglycemic effect. ![]() Thanks to research carried out on the fruits of this shrub, many properties described for thousands of years regarding their pro-health characteristics have been confirmed. Goji berry Lycium barbarum L., commonly known as goji berry, may be an example of a superfood. Despite discrepancies between predicted and observed bacterial growth due to the antimicrobial effect of the derivatives of goji berries, the models were validated as „overpredict”, i.e., „fail safe”, and may be used to prognose the stability of these products in the given temperature profile. The best-performing models were constructed for extract (Bias factor B f 1.33, Accuracy factor A f 3.43) and milkshake ( B f 1.29, A f 1.65) in a profile simulating delayed refrigeration (22.5 ☌–9 ☌–23 ☌). Using ComBase ®, a microbiological response to the delayed cooling of goji berry extract and the milkshake with the addition of goji berries was predicted and the model’s accuracy assessed. subtilis was a model for the study of its microbiological stability. The milkshake inoculated with the reference B. The phenolic compounds with the highest concentrations were in turn: 3-hydroxybenzoic acid, gallic acid, procyanidin B2, and catechin. The extraction of dry berries in water at 70 ☌ for 72 h produced an extract showing radical inhibition of 64.9% and a total phenol content of 63.6 mg g −1. ![]() Within this study, the microbiological stability of the milkshake, with the addition of berries from NingXia Province and their extract, was evaluated using the ComBase ® prognostic model. Goji fruits and extracts are often used as ingredients in popular homemade milk cocktails. Lycium barbarum L., used in Chinese traditional medicine for centuries, has gained popularity in Europe in the last decade because of its health-promoting properties assigned to phenolic compounds and antioxidant activity. ![]()
