Strawberry is one of the most preferred fruits all over the world due to its characteristic properties. Due to the morphological structure of fresh strawberries after harvesting, quality losses are observed during cold storage. Therefore, industrial washing of fresh strawberries is especially important for reducing microbial load and increasing shelf life. Demand for the new methods as an alternative to the chemicals used in industrial washing of fruits and vegetables is increasing due to consumer-related health concerns. Ultrasonic washing is a preferred innovative method in terms of reducing the microbial load and maintaining quality properties compared to chemical washing processes. In this study, fresh strawberries were washed with ultrasound (550 W/35 kHz) and peroxyacetic acid (40 ppm) after harvesting. The pH, total acidity, water soluble dry matter (brix), vitamin C, total phenolic content, antioxidant capacity, total viable, mold and yeast count analyses were performed in every two days during 14 days of cold storage of washed strawberries. Ultrasonic washing was found to be more effective in reducing microbial load and preserving bioactive properties of strawberries compared to other method due to its cavitation effect.

Transmission of pathogenic microorganisms from contaminated surfaces to hands could cause various diseases. In this study, the microbiological status of shopping carts was investigated in İzmir. To determine where the samples will be taken from and to get user’s opinions about hygiene, a survey was carried out. Total of 100 samples were taken from shopping carts in 20 different markets between February and April, and total viable counts and Escherichia coli counts were applied in samples. Total viable counts of shopping cart handles for 100 samples were found between 0,82– 4,88 log CFU/10 cm2. Coliforms and E.coli were not found in the analysed samples. According to the results, it is seen that the shopping carts have different levels of microbial load; the market environment and the users are effective on these profiles. It has been determined that cleaning and disinfection processes should be applied to improve the hygienic condition of shopping carts and high numbers of microorganisms in the shopping cars might be a potential risk for public health.

Ganoderma lucidum (Curtis) P. Karst., known as “Lingzhi” in China or “Reishi” in Japan, is a well-known medicinal mushroom and traditional Chinese medicine, which has been used for the prevention and treatment of bronchitis, allergies, hepatitis, immunological disorders and cancer. G. lucidum is rarely collected from nature and mostly cultivated on wood logs and sawdust in plastic bags or bottles to meet the demands of international markets. Diverse groups of chemical compounds with pharmacological activities, isolated from the mycelia and fruiting bodies of G. lucidum are triterpenoids, polysaccharides (β-D-glucans), proteins, amino acids, nucleosides, alkaloids, steroids, lactones, lectins, fatty acids, and enzymes. The biologically active compounds as primarily triterpenoids and polysaccharides of G. lucidum have been reported to possess hepatoprotective, antihypertensive, hypocholesterolemic, antihistaminic effects and antioxidant, antitumor, immunomodulatory, and antiangiogenic activities. Several formulations have been developed, patented and used as nutraceuticals, nutriceuticals and pharmaceuticals from G. lucidum’s water or ethanol extracts and rarely purified active compounds. As the result of clinical trials, various products have commercially become available as syrup, injection, tablet, tincture or bolus of powdered medicine and an ingredient or additive in dark chocolate bars and organic fermented medicinal mushroom drink mixes such as green teas, coffees, and hot cacaos. This review has intended to give and discuss recent knowledge on phytochemical and pharmacological compositions, therapeutic and side effects, clinical trials, and commercial products of G. lucidum.
