A fraction of large granules was separated from native starch with the sedimentation method and acetylated with various doses of acetic anhydride (6.5, 13.0 or 26.0 26 cm3/100 g starch). The starch acetates were then annealed at slightly lower temperatures than their pasting temperatures. The annealing process caused an almost twofold increase in the resistance to amylolysis and a threefold increase in the swelling power of the modified starch preparations. The heat of phase Citation: Zi˛eba,T.; Wilczak, A.; transition decreased almost two times and the range of starch pasting temperatures over two times, Kobry´n,J.; Musiał, W.; but the pasting temperature itself increased by ca. 10 ◦C.

The present invention concerns infant formula thickened with a potato starch or waxy starch which contains a high 5 level of amylopectin. Starch is composed of two distinct polymer fractions: amylose and amylopectin. Amylose is the linear fraction consisting of a-1 ,4 linked glucose units. Amylopectin has the same structure as amylose but some of the glucose units are combined in an a-1 ,6 linkage giving rise to a branched structure.

  • Matzo Balls for Passover for Our Passover Seder
    Matzo balls for Passover For our Passover Seder (traditional evening meal on the first night of Passover) my mother always made Matzo ball soup. Her famous soup was a chicken broth with matzo ball dumplings made from matzo meal, eggs, water, and schmaltz (chicken fat). We’ve gotten a little more modern as we make matzo balls in my house by using light oil instead of the schmaltz. There’s an art to making matzo balls as there are some common mistakes that make the dumplings heavy instead of light and fluffy. Here’s my recipe and instructions. Matzo Ball Recipe 1 cup Matzo meal ¼ cup light corn oil ¼ cup water 1 tsp. salt dash of pepper 4 large eggs 1 TB. fresh parsley, chopped Beat the eggs with the water, oil, salt, pepper, and parsley. Add matzo meal and stir until well mixed. Refrigerate the mixture for at least one hour. After chilling, shape walnut-sized dough into balls with your wetted hands. Keeping your hands wet keeps the matzo from sticking as you form the balls. Drop balls into boiling salted water and cook for 30 minutes. Remove the matzo balls from the water with a slotted spoon and add them to your chicken soup. This recipe makes about 20 1-inch matzo balls which is about 6 servings. The key mistakes that people make are to not leave enough time to adequately chill the mixture before dropping the balls into boiling water; stirring the mixture too much; and cooking the matzo balls in the chicken soup instead of salted water first.

    jamie geller’s VEGAN HOLIDAYS 14 MEATLESS AND DAIRY-FREE TRADITIONAL JEWISH RECIPES “My mommy doesn’t let” is a favorite saying amongst my little ones. They chant it more than they live it, but, it’s a start. So today I feel like telling the whole world I would be vegan but “my family doesn’t let”. Most of them are serious carnivores and so living this lifestyle 24/7 would mean double the work in the kitchy for me which is super hard for me to wrap my head (and time-starved life) around. I started eating macrobiotic (a cousin of the vegan diet) with my mom in the 90s before it was envogue and when it was more cult-ish in style. We’d go to these invite-only macrobiotic supper clubs and that’s when I fell in love with tempeh, kanten and wheatgrass shots. So this Vegan Holiday ebook is an ode to my past life, and a hope and dream for my future. A time when vegan recipes can live side by side with their carnivorous “cousins” at my dinner and holiday tables. (These recipes are sooo good I may slip in a swap and see if my family notices.) An essential tip for successful vegan cooking is quality ingredients and specifically extra virgin olive oil. This healthy fat stand-in makes all the difference.

  • Ultrafiltration of Partially Degraded Starch Solution
    Ultrafiltration of partially degraded starch solution Contribution of fouling mechanisms to the flux decline and effect of operating parameters Doctoral Thesis by Berhanu A. Demessie Submitted to Department of Chemical Engineering Norwegian University of Science and Technology (NTNU) In partial fulfillment of the requirement for degree of Doctor Engineering (Dr. Ing.) Trondheim, 2002 URN:NBN:no-3327 Dr. Ing thesis NTNU 2002:87 By: Berhanu A. Demessie Supervisor: Professor Norvald Nesse August, 2002 ISBN 82-471-5487-0 ISSN 0809-108X URN:NBN:no-3327 Summary iii Summary Desizing wastewater is largely responsible for the chemical oxygen demand (COD) load in the textile industry wastewater. A larger portion of COD comes from degraded starch in desizing wastewater. Removing the starch from the wastewater by an ultrafiltration process may reduce the environmental problem caused by the textile factory. If the treatment is made in such a way that all starch components are removed from the wastewater, the treated water can be reused by the factory. If the starch in the concentrate is stable, it can also be reused as a sizing agent. This will give the factory an economic advantage. In this thesis we have studied the fouling mechanisms involved in the ultrafiltration of solution with partially degraded starch in order to find the treatibility of such solutions. The work has mainly been directed to uncover how the different fouling mechanisms depend on the operating parameters, and to find the performance of selected membranes. In addition, different models were evaluated for their validity in predicting the performance of the membranes and the data was fitted to the model that give the best prediction and are physically more meaningful.

Abdelmaguid, Wafaa, M. M. Abozeid and Ramadan, M.T. Food Technology Department, National Research Centre, Egypt *Corresponding author A B S T R A C T Native starch samples were prepared from potato tubers and modified by heat- moisture treatment (HMT), microwave, ultrasonication and syneresis methods. All modification methods reduced contents of protein, fat, ash and amylose but increased Amylopectin content in modified potato starch samples compared with those of native starch. Both HMT and microwave methods improved water absorption capacity (WAC) (g/g). While, all modification methods tend to reduce K e y w o r d s swelling power (g/g) in modified potato starch samples. The value of solubility (%) of modified starch with ultrasonication method (14.82%) was higher than that Potato starch, present in native starch (13.25%). Microwave modification method increased values of pasting temperature (oC), Pv (peak viscosity during heating), Hv (hot Heat-moisture o o paste viscosity at 95 C), Hv30 (viscosity after 30 min holding at 95 C) and Cv (cold treatment o (HMT), paste viscosity at 50 C) in this modified starch sample compared with those of Microwave, native starch sample. All pasting properties values of two modified starch samples Ultrasonication, with ultrasonication and syneresis except BD (break down) values were lowered.
