UCO-979C is a probiotic strain possessing anti- and immunomodulatory activity. The aim of this work was to examine if this strain maintains its probiotic properties and its viability when added to dairy-based ice creams (cookies and cream, Greek yogurt, and chocolate with brownie) or to fruit-based ice creams (pineapple and raspberry) stored at -18 °C for 90 days. The probiotic anti- activity using the well diffusion test, its immunomodulatory activity was measured using transforming growth factor beta 1 (TGF-β) cytokine production by human gastric adenocarcinoma (AGS) cells, and its viability was measured using the microdrop technique. Assays were performed in triplicate. The UCO-979C strain maintained strong anti- activity in dairy-based ice creams and mild activity in fruit-based ice cream. The production of pro-inflammatory cytokine TGF-β on AGS cells was higher in the probiotic recovered from Greek yogurt ice cream, maintaining a viability exceeding 10 colony-forming units/mL. The addition of the probiotic to ice creams did not significantly influence the physicochemical properties of the product. These data show the great potential of the UCO-979C strain in producing probiotic dairy-based and fruit-based ice creams.

The food and pharmaceutical sectors frequently utilize vanillin (VAN), a food ingredient with a pleasing flavor and aroma. However, excessive consumption of VAN causes several health problems, including liver and kidney damage, headaches, skin conditions, nausea, and vomiting. To prevent health problems, it is crucial to identify and control the amount of VAN in food and drugs.

Fish skin is the basic source of gelatin, which contains a high amount of protein. The results show that the proximate compositions (protein, fat, ash, moisture, fiber, carbohydrate, and total energy) of the optimized ice cream product with ingredient compositions of (30% milk, 40% avocado pulp, 10% sugar, 15% gelatin, and 5% cream) show values of 3.

Introduction: The adverse health effects of sugar-sweetened beverage intake are well-established, but the implications of overall added sugar intake remain unclear. We investigated the associations between intake of added sugar and various sugar-sweetened foods and beverages and risk of 7 cardiovascular diseases in 69,705 participants aged 45-83 years (47.2% female) from the Swedish Mammography cohort and Cohort of Swedish men.

In our previous work, wheat gluten (WG) has been modified by pH-shifting treatment combined with heat to improve solubility and emulsibility. In this study, the high-soluble modified wheat gluten (M-WG) as an emulsifier in ice cream was investigated. Compared to monoglycerides (MG) and soy protein isolates (SPI), the ice cream emulsion prepared with M-WG exhibited smaller droplet sizes and a more consistent dispersion.

The heart of the date palm is a nutrient-rich vegetable found at the center of palm trees, abundant in protein and dietary fiber, primarily made up of carbohydrates. Preliminary studies indicate that the heart of the date palm possesses healing properties, exhibiting potent cytotoxic effects against HepG2 cells, suggesting its potential in cancer treatment. A low-fat ice cream was created using camel milk, enriched with varying amounts of heart of date palm-4 %, 8 %, and 12 % of the mix-as a source of bioactive compounds, protein, and carbohydrates.
