This research aims to study the physicochemical and sensory evaluation of high energy cereal bars (HCB) and their consumer acceptability using logistic regression. The HCB was prepared and formulated under using a mixture design (d-optimal) experiment with three centerpoints, namely, cereals (60–66%) fruits (14–20%), and sweeteners (20–26%). The regression analysis indicated that the three main ingredients affected physicochemical properties (color value, hardness, and stickiness), chemical properties (aw, total carbohydrate, gross energy, reducing sugar, non-reducing sugar, and total carotenoid), and sensory properties. The optimum content of cereals, fruits, and sweeteners for HCB was found to be 60.45%, 19.55%, and 20%. This indicates that puffed rice, roasted nuts, cereal seed, mixed fruits, corn syrup, and honey can provide high consumer product acceptance and purchase intention for a cereal bar and can be used to develop a high-energy cereal bar product desirable for the consumer market.
Turmeric (Curcuma longa L.) powder is widely used as a spice and seasoning in Asian countries. This study investigated the effect of turmeric extracts on the anticancer activity of Huh7 and HCT 116 cells. The curcumin bioactive compounds were extracted using various methods such as microwave-assisted extraction (MAE), ultrasound-assisted extraction (UAE) and traditional extraction (TDE). The yield of dried extracts from MAE was found to be the highest at 17.89%, followed by UAE and TDE, with 11.34% and 5.54%, respectively. Antioxidant activities such as TPC, DPPH and FRAP from MAE were higher than those of UAE and TDE. The total curcuminoid contents from the novel extractions were higher than those from traditional extraction methods. For instance, curcuminoid contents from MAE, UAE and TDE were 326.79, 241.17 and 215.83 mg/g, respectively. Due to having the highest bioactive compounds and extraction yield, turmeric extract from MAE was used to investigate the potential anticancer properties. The extract showed significant cytotoxic potential against the human liver (Huh7) and human colon (HCT116) cell lines, in concentrations ranging from 31.25 to 1000.00 µg/mL. Turmeric extracts using MAE have potential anticancer effects on Huh7 and HCT116 cells. This study serves as scientific data for the chemotherapeutic properties of turmeric extracts and their use as functional ingredients.
