People have affection for confectionary products. Confectionery products are of two types, baker and sugar confectionary. Dark chocolates belong to sugar confectionery class. The present invention was carried out on the preparation of synbiotic dark chocolates. Synbiotics are food products that contain both prebiotics and probiotic microorganisms, wherein prebiotics encourage the growth of probiotics. The synbiotic dark chocolates were amended with flax seeds ( L.) as a prebiotic for LAB. Flax seed contains fiber and phenolic antioxidants which makes them prebiotic source. The isolated LAB culture, which was identified as based on morphological, biochemical tests and MALDI-TOF, showed the properties of a probiotic culture viz., tolerance to sodium chloride, bile salt, pH, and temperature, sensitivity to antibiotics, nonhemolytic and production of hydrogen peroxide. Cytotoxic activity of the cell free supernatant was assessed against MDA MB 231 and neuroblastoma cell line. Probiotic strain showed 48% and 30% cytotoxicity against MDA MB 231 and neuroblastoma cell line. The synbiotic chocolate was found to have more antioxidant activity, i.e. 90 U/mL by DPPH assay and 200 (μg Trolox/mL) by FRAP assay. The synbiotic chocolate prepared will be beneficial for the gut health of the humans and will also have excellent nutritional value.

Fat, sugar, theobromine, and caffeine are important compounds in chocolates that influence the physico-chemical and sensory characteristics of the products. These parameters commonly are determined with conventional, time-consuming, environmentally pollutant methods. In this study, near infrared spectroscopy (NIRS) coupled with partial least square regression (PLSR) was used to predict the quantity of these compounds.

Background And Aims: Cocoa may have prebiotic effects and improve gut barrier function. However, it remains unclear whether dark chocolate can reduce lipopolysaccharide (LPS) levels in patients with metabolic dysfunction-associated steatohepatitis (MASH). This study aims to evaluate the effect of dark chocolate compared to milk chocolate on endotoxemia in patients with MASH.

Article Synopsis
- The study focused on three coffee estates in New South Wales, aiming to enhance the flavor profiles of Australian coffee through different processing methods (wet fermented and non-fermented).
- Researchers analyzed 33 volatile compounds in both green and roasted coffee beans, identifying various esters, alcohols, acids, and more, while also assessing sensory characteristics like appearance and flavor.
- Findings indicated that wet fermentation improved certain desirable aromas and flavors in coffee, particularly enhancing notes associated with premium coffees, such as "black tea leaves" and "dark chocolate."

Chasteberry extract offers considerable phytotherapeutic benefits, particularly in alleviating premenstrual syndrome (PMS) symptoms. However, its hydroalcoholic nature leads to a bitter taste and a burning sensation, presenting challenges for direct consumption or incorporation into new food products. This study aimed to address these issues by encapsulating concentrated chasteberry extract using spray-drying with Arabic gum, followed by spray-chilling with vegetable fat as carriers.
