: The objective of this study was to evaluate the effects of fat levels (200 g·kg –1 meat and 500 g·kg –1 meat) and types [lard, glycerolised lard (GL), and purified glycerolised lard (PGL)] on the quality and sensory characteristics of emulsion-type sausages. As observed, at the same type of fat, the low-fat sausage (200 g·kg –1 meat) had a significantly higher L *-value (lightness) and lower cooking loss and total expressible fluid ( P < 0.05) than the high-fat sausage (500 g·kg –1 meat) and exhibited a denser and more homogeneous microstructure. Additionally, T 23 (relaxation time) of the low-fat sausage shifted toward a slower relaxation time, and higher A 23 (peak area) was found, which suggested the water mobility was restricted. However, at the same fat content, the low-GL and low-PGL sausages showed bet-ter textural properties and superior overall acceptability from sensory evaluation compared with the low-lard sausage ( P < 0.05). Still, they have no significant differences ( P > 0.05). Therefore, lard-based diacylglycerol could be effectively applied as a fat replacer in emulsion-type sausages with low-fat contents to produce healthier meat products.

: A traditional Czech bakery white bread product is commonly made with directly mixed dough with the addition of yeast. In order to be able to reduce the salt content of the final product without compromising its acceptability to consumers, the dough was prepared with the addition of pre-ferments and wheat sourdoughs. The aim was to deepen the flavour background of the product and thus have a positive effect on its sensory properties. Wheat sourdoughs were prepared and tested using starter cultures and matured under different conditions. The resulting products were tested both sensorially and by means of precise physical methods

: Among the varieties of pineapples, honey pineapple is suitable to be processed as a probiotic beverage. The study aimed to evaluate the honey pineapple juice as a growth medium for Lactiplantibacillus plantarum sub-sp. plantarum Dad-13 probiotic strain. The pineapple juice was fermented by adding a starter culture of L. plantar-um Dad-13. The fermentation time (0, 4, 8, 12, 16, 20, and 24 h) was used as a variable. The number of L. plantarum Dad-13 cells increased significantly after fermentation ( P < 0.05). In acidic pineapple juice L. plantarum Dad-13 can still grow more than 2 log cycles. After 16 h, the results showed the best characteristics with cell count (8.86 log CFU·mL –1 ), pH (3.52), and titratable acidity (0.59%). To balance the sour taste, the 8% sucrose addition was the most preferred by the panellists ( n = 67), with a 5.74 (slightly like) overall acceptance score. After 42 days, there was no significant decrease in cell viability. The number of cells on day 42 was 8.81 log CFU·mL –1 with significant changes in pH and titratable acidity. The study showed that honey pineapple juice is a suitable growth medium for L . plantarum Dad-13.

: Chips made from maize semolina are rarely mycotoxin analysed because they are classified as low-risk foods in routine legal control plans. It is essential to foresee the health risks these snack foods may pose in the medium and long term, whose consumption frequency and quantity have increased with the changing consumer behaviours during the pandemic. The most outstanding development in mycotoxin analysis in recent years has been the use of high-pressure liquid chromatography together with mass spectrometry (LC-MS/MS ) as a detector. For aflatoxin (AF) B 1 , B 2 , G 1 , G 2 , ochratoxin A (OTA), zearalenone (ZEN), deoxynivalenol (DON), fumonisin B 1 (FB 1 ), fumonisin B 2 (FB 2 ), citrinin (CIT), HT-2 toxin, and T-2 toxin determination in our samples, the LC-MS/MS analysis method with electrospray ionisation interfaces was utilised. Aflatoxin B 1 levels in 22.7% of the samples (2.01–17.49 μg·kg –1 ) and total aflatoxins (TAF) in 26.7% of the samples (6.71–24.67 μg·kg –1 ) were determined to exceed the limits defined in the Turkish Food Codex Contaminants Regulation. CIT could not be detected in any of the samples. ZEN + DON + OTA was found in 21.3% of the samples, DON + TAF + total fumonisins (FUM) in 19.3%, and TAF + ZEN + FUM in 18.7%.
