    This research aimed to develop a nutritious instant purple sweet potato soup (PSP) combination with a variety of vegetables and freeze-dried chicken. The nutritional characteristics of the product were evaluated. The current study employs principal component analysis (PCA), consumer preference mapping, and check-all-that-apply (CATA) data processing to describe sensory instant mixed soup attributes. The results showed that the soup was made from the formula F2 (PSP flour 47.5%, orange-fleshed sweet potato flour 12.5%, potatoes 6%, banana 7%, mushroom 8%, petit poise 3%, pumpkin 5%, protein powder 5% and cream powder 6%) gave good quality, high sensory value and attractive colors product. The PCA identified important soup attributes such as sweetness, milk flavor, vegetable odor, and color. Adding 15% freeze-dried chicken improved the quality of mixed soup products with energy distribution from macronutrients: proteins 24%, carbohydrates 65%, and lipids 10%. The anthocyanin and β-carotene content analyzed from the product was 13.1 mg/100 g and 370.2 μg/100 g. Score analysis according to the CATA model with two main components accounting for 95.57% of the variance in sensory attribute data, showing liking attributes of mixed soup sample that the panelists preferred in color, flavor, chicken meat distribution, and sweetness. The essential nutritional characteristics of mixed soup have been carefully analyzed.

    Background. Low GI and alkaline food products have been the attention of research aimed at supporting the health of consumers. Materials and methods. This study aims to develop a waffle formula for a low energy, alkaline food with a high nutritional value and low glycemic index (GI) from the partial replacement of wheat flour with green banana flour and potato starch ranging from 2.5 to 12.5% (of the total weight of flour used) in the formulas. To assess this, the quality of the product was analyzed. Results. The research results show that low GI, alkaline waffles with a high nutritional value can successfully be prepared with green banana flour and potato starch substitutes, at 12.5 and 7.5% of the formula respectively (w/w) (formula F5). The nutritional value of the product for one waffle (110 g) is 305.6 kcal, 40.9 g carbohydrates, 9.2 g protein, 11.7g fat and 1.43 g fiber, with an estimated GI of 62.54 ±0.46 (lower than a waffle made entirely of wheat flour, which had a GI of 76.38 ±0.90). The macronutrient energy distribution (carbohydrate:protein:lipid of 53.6:12.1:34.3) meets the recommendations of the AMDR. Conclusion. The F5 product has proper nutritional characteristics, low GI, and an estimated negative PRAL (–0.67), indicating that the waffles tend to cause more alkalinity in the body when consumed. Further studies should be considered to develop and improve the production of waffles with better nutrients and biological functional properties
