    Research was conducted to develop a sandwich bread with added Gac aril. Effects of Gac aril (5, 7, and 9%), added sugar content (8.6, 10.3, and 12%), and instant dry yeast used (0.3, 0.4, and 0.5%) to bread quality and sensory value of the products were performed. The relationship between the dependent variables such as β-carotene, lycopene, and volume expansion and three independent variables including Gac aril, sugar and dry yeast content was analyzed using multiple regression analysis. It was observed that the optimum responses of β-carotene, lycopene, and volume expansion were determined as 14.78 µg/g, 59.14 µg/g, and 5.3 times, respectively. To achieve those optimal values, the optimization conditions of various input variables, the percentage of Gac aril, sugar, and dried yeast were found to be 8.55%, 9.76%, and 0.5%, respectively, which, on confirmation, showed a high quality sandwich bread. The optimal parameters were also verified. Sensory evaluation showed that the sandwich bread prepared with 8.55% and 9% Gac aril gave a higher acceptance score than the lesser content and control sample. Preference mapping also showed more than 80% of the participants loved these products.

    Background. Macaroni is a common side dish or main dish that is served with sauces. Traditional macaroni is typically made using flour, water and eggs and is typically yellow in color. It has a high amount of starch and is deficient in fiber, minerals, vitamins and bioactive components. Material and methods. The effects of Gac aril (3, 5, 7 and 9%) and xanthan gum (1, 1.5 and 2%) on the quality characteristics of macaroni were investigated. Macaroni was evaluated for cooking quality (cooking loss, volume increase, rehydration ratio), colour, chemical (β-carotene and lycopene) and structure/microstructure to assess the impact of experimental factors. Results. The proximate composition of Gac aril was analysed and showed that Gac aril added to macaroni recipes is a food ingredient capable of enhancing bioactive compounds (β-carotene and lycopene). Studies on the combined effects of the addition of Gac aril and xanthan gum have shown that macaroni with 7% gac and 1.5% xanthan gum used resulted in a beautifully colored macaroni product (before and after cooking), good structure, high β-carotene and lycopene content (15.26 μg/g and 61.26 μg/g, respectively). The cooking quality of the macaroni was thoroughly analyzed. The rehydration rate and volume both increased with the addition of Gac aril and the xanthan gum content increased. However, the cooking loss was shown to be slightly different. The cooking loss increased as the content of Gac aril supplement was increased, while the added xanthan gum reduced the cooking loss. Conclusion. The effects of macaroni enrichment with gac and the use of xanthan gum on product quality were noted. The physicochemical components, bioactive compounds, firmness, microstructure and cooking quality of the analyzed products emphasized the role of the ingredients used in the results obtained. The microstructure of the product has also been improved and ensures the desired product quality attributes. Further studies are needed in order to be applied at an industrial scale and with high consumer acceptance of this new product.
