摘要

Scientifically, blackcurrants have long been regarded as having considerable health benefits, due to their high levels of vitamin C and bioflavonoids, including anthocyanins and phenolic acids. The increasing interest in functional foods has led processors to find new resources to meet this demand, and dried candied black currant can be one processing product offered to consumers as a healthy snack. To determine the shelf life it is necessary to choose appropriate packaging materials and evaluate their influence on the quality of product during the storage time. The results of the research showed that the total amount of bacteria and yeast are significantly affected by the material used for packaging. The content of vitamin C throughout the storage period of dried candied black currants in PP bags and in PLA pouches decreased on average by 28.6% and by 32.3%, respectively. The changes in total phenolic content were insignificant (3.7-4.3%) and substantial difference between packaging materials was not observed. Due to the relevant content of polyphenols including anthocyanins, dried candied black currants are characterized by high antiradical activity (46.6 mmol g~(-1) Trolox by DPPH and 40.7 mmol g~(-1) Trolox by ABTS). The antiradical activity in the dried candied black currants during the storage time of six month decreased on average by 30%.

ABSTRACTudThe purpose of this research is to obtain an optimal formulations of Black mulberry leaves dried noodle product by using Design Expert Application with Design Mixture D-optimal method.udThis research was done with two phases. The preliminary procedures research is to determine levels of antioxidant activity, chlorophyll content, and the levels of tannin that was contained in black mulberry leaves, the black mulberry leaf flour, a pare fruits, and pare flour. Primary research is to determine the best formulation by using a Mixture Design Expert Design D-optimal method, for a purpose is to optimized the Black mulberry leaf dry noodle. Responses in this studies are a chemical analysis response by using a crude fiber analysis and protein analysis. Physical response is water absorption. Sensory response are color, flavor, and odor.udBlack mulberry leaves dried noodles was made from wheat flour, black mulberry leaf flour, and pare flour, other materials such as an eggs, water, salt, and sodium bicarbonate, of the 16 formulations that has offered to produce an optimal formulation based on desirability which contains 39.69 Flour,14.25 Black Mulberry Leaves flour, 3.06 Pare fruit and flour amounted, and other materials are 30 water, 10 eggs, 2 salt, and 1 sodium bicarbonate. The formulation has been result by program 11,05 crude fiber content, 12.93 protein, 274.31 water absorption, 4,31 for color attribute, 3,87 for taste attribute, and 3,71 for aroma attribute.ududKeyword: Black mulberry leaf dried noodles, optimization.
