<p>Coffee husk and coffee pulp are by-product of coffee fruit and bean processing, can be considered as potential functional ingredients for food production as coffee cherry flour (CCF).  The CCF contains a lot of carbohydrates, proteins, caffeine, tannins, and polyphenols. In this study, CCF was combined with modified arrowroot starch (MAS) and modified cassava flour (MOCAF) into cookies and improvement on the physical, chemical, and nutraceutical properties of the cookies were studied. The cookies consisted of 20 % of MOCAF and 80 % mixed of modified arrowroot starch and CCF in five levels (80 %:0 %; 75 %:5 %; 70 %:10 %; 65 %:15 %; 60 %:20 %) and objective physical, chemical, and nutraceutical properties of the cookies were assessed. The results showed that the total dietary fiber content was enhanced from 11.69 % to 19.48 % with a high proportion of 20 % CCF. The cookies added with CCF displayed enhanced antioxidant activity. Acceptable cookies were obtained by adding 5 % CCF. Thus, the results implied that cookies with CCF addition obtained dietary fiber enriched cookies with improved antioxidant activity.</p>

Increasing global population and urbanization demands enhanced food and feed crop production, but due to several reasons, the areas of fertile agricultural lands are reducing worldwide. The market of growing substrates, soil amendments, and improvers still is based on peat extraction and processing. Due to peat's fossil origin, it can be considered environmentally unfriendly and unsustainable. Seeking peat-substituting materials is of crucial importance on a global scale and may become a vitally significant assignment for future generations. The necessity for peat-free soil amendments is also directed by the targets of circular economy and environmental sustainability goals, leading to reducing or abandoning the use of fossil resources and paying attention to waste utilization as secondary raw material. This paper aims to discuss general features of peat-free soil amendments as well as provide efforts into the use of secondary raw materials such as biomass ashes for the elaboration of peat-free soil-improving products. As a case example, may serve a description of the peat-free product made by rotary drum granulation from biomass fly ashes (energy production waste) and local freshwater sediments in a mass ratio mixture of 67:100, optimally applicable for soil improvement at a rate of 50 g L -1 . Besides, regional opportunities in Indonesia and Latvia are referred. It was concluded that peat-free soil amendment elaboration can be better implemented on a regional scale after assessing agricultural needs, soil specifics, and available raw material variety applicable as ingredients in soil-improving products.

Sweet bread is associated with smooth texture and high carbohydrate content, tasty and filling - quality that makes it preferred for snack. The key is in formulating raw material and other components. Commonly, sweet bread has short shelf life. Frozen dough could be the solution to this problem, and glucomannan addition during freezing process should be able to improve its physicochemical characteristics. This research aims to determine the effect of adding modified arrowroot (Maranta arundinacea L.) starch (MAS) as substitution, and glucomannan as frozen dough cryoprotectant toward sweet bread’s physicochemical. Randomized Complete Block Design Factorial (RCBD) was applied, and two factors were studied. The first factor was modified arrowroot starch (0.00%, 3.75%, and 7.50%) and the second was glucomannan (0.0%, 0.5%, and 1.0%). The best result was combination between MAS 3.75% and glucomannan 0.5%, reaching dough expansion volume range of 50% to 60%, bread expansion volume range of 77% to 80%, hardness range of 2 N mm-2 to 3 N mm-2, elasticity range of 88% to 96%, moisture content of 16% to 19%, ash content of 1.4% to 1.7%, fat content of 10% to 15%, protein content of 5%, and carbohydrate content of 51% to 66%. MAS is able to substitute wheat flour in bread production only if it is combined with glucomannan.

Abstract. The purpose of this study, to see the interaction of the effect of drying time and temperature of the carbohydrate content of carbohydrates, the interaction of the effect of coordinated time and temperature on mocaf, and the effect of time and optimal drying temperature of mocaf. The study used a factorial randomized block design with a factor of 1, namely the drying time (8 hours, 12 hours, 24 hours) and factor 2, namely the drying temperature (50°C, 70°C, 80°C). The preliminary stage of this research is soaking the cassava chips with 5% salt. The next step is making yeast fermentation mocaf with drying time and temperature treatment using a cabinet dryer. The parameters analyzed were moisture content, ash content, fat content, protein content, carbohydrate content, and color content. The results showed that the treatment of drying time of 8 hours and drying temperature of 70°C is the best treatment measured by the De Garmo test. The test results showed that the treatment had a water content of 10.08%, a protein content of 0.73%, a fat content of 0.06%, an ash content of 8.35%, carbohydrate content of 80.75%, a brightness level (L) is -11.6, the level of redness (a +) is 3.85, and the level of yellowness (b +) is 9.3.

The research was conducted to determine the effects of Butyrylated Arrowroot Starch (BAS) to the digesta profile and Short Chain Fatty Acids (SCFA) molar ratio. The research was conducted by using simple complete randomized design (CRD). The treatment tested was feed type, which consists of 5 levels, namely natural arrowroot starch, BAS with Degree of Substitution (DS) 0.053; 0.120; 0.187 and AIN93 natural feed. The study was conducted by using 30 Sprague Dawley rats, which were divided into 5 groups, each group consisting of 6 tails. Feeding treatments were given from dayseven until day 33. On day-34 analysis was conductedof the digesta profile and the SCFA molar ratio. Based on the analysis results, it is known that BAS feeding increased digesta weight, decreased digesta pH and increased digesta water content when compared with the AIN93 standard feed. Largest amount of digesta, lowest digesta pH, and highest water content of digesta, respectively 7.19 g, 6.53 and 91.23%, wasobtained from rats fed BAS with DS 0.187. The molar ratio of butyric acid in digesta also increased along with the increasing BAS DS.
