  • Added Beta-Glucan As a Source of Fibre for Consumers
    ESPOO 2006 VTT PUBLICATIONS 594 View metadata, citation and similar papers at core.ac.uk brought to you by CORE VTT PUBLICATIONS 594VTT PUBLICATIONS Added ß­glucan as a source of fibre for consumers provided by Helsingin yliopiston digitaalinen arkisto The intake of dietary fibre does not currently meet the recommendations in many Western countries, and it is important to find new ways to increase its intake. The aim of this thesis was to investigate whether providing foods enriched with ß•glucan would be a feasible strategy for improving consumers’ dietary fibre intake regarding the sensory properties and consumer acceptance of these foods. ß•glucan is a good option for fibre enrichment of foods because of its proven capability to reduce elevated blood cholesterol levels and to balance blood glucose and insulin response after meals. The study showed that dietary fibre had a positive image among Finnish respondents and it was considered important for health. Beverages and soups with added ß•glucan were acceptable regarding their sensory characteristics, thus being feasible carrier products for ß•glucan and providing a possible non­traditional source of dietary fibre. Liking for the products with added ß•glucan was the most important factor affecting the willingness to use them, indicating that the sensory quality of products with added dietary fibre with health benefits has to be acceptable, only then consumers are willing to buy them.

Materials and Methods: In this paper, the mechanism of action of a mix in capsules of 0.6 g of β-Glucan (Active hexose correlated compound “AHCC” and β-Glucan 1,3-1,6) on the neoplastic cell line transcriptome has been explored. The cellular models used were Caco2 and LS174T cell lines. Transcriptome analysis was performed by RNA expression analysis of transcripts of both single and multiple samples. The analysis was completed with the aid of information technology. Results: ROS (Reactive Oxygen Species) decrease following glucans treatment (Figure 1) com- bined with a marked improvement in the Redox control of SOD1 (Superoxide Dismutase 1) (Figure 2), which is pre-sent in the cytosol of all eukaryotic cells with copper and zinc (Cu-Zn-SOD). Follow- ing glucan mix treatment, COX-2 (cyclooxygenase-2) expression levels showed a marked reduction (Figure 3A).

  • Carbohydrate Counting
    Carbohydrate Counting What is Carbohydrate Counting? Carbohydrate counting is a meal-planning tool that many people use to manage their blood sugar. Carbohydrate counting, or ‘carb counting’, is done by tracking the amount of carbohydrates eaten at meals and snacks. Carbohydrates are a type of nutrient found in starchy and sweet foods. When starchy or sweet foods are eaten, the body breaks the carbohydrates in the foods down into glucose. This glucose is released into the blood. Another name for glucose in the blood is blood sugar. There are four steps in carbohydrate Foods with carbohydrates: counting: • Soda pop, juice, Tang, Kool-Aid, and other sweet drinks • Starchy vegetables like potatoes, corn, squash, beans and peas 1. Timing • Rice, noodles, oatmeal, cereals, breads, crackers 2. Amount • Milk and yogurt 3. Balance • Beans 4. Monitoring • Chips, cookies, cakes, ice cream Step 1: Timing • Fruit and fruit juice A moderate amount of carbohydrate foods gets broken down into a moderate In diabetes meal planning, one choice of carbohydrates has about 15 grams of amount of blood sugar. carbohydrates. For most people trying to keep their blood sugars in a healthy range, eating about 3 or 4 choices of carbohydrate foods (45-60 grams) at a meal is a good place to start. A good amount of carbohydrates for snacks is usually around 1-2 carb + = Blood sugar 140 choices (or 15-30 grams). Food List of Carbohydrate Choices Two hours after eating one sandwich, this person’s blood sugar is 140.

  • Fractionation of Barley Flour Using Elusieve Processing: a Combination of Sieving and Air Classification
    FRACTIONATION OF BARLEY FLOUR USING ELUSIEVE PROCESSING: A COMBINATION OF SIEVING AND AIR CLASSIFICATION R. Srinivasan, K. B. Hicks, R. K. Challa, J. Wilson, M. Kurantz, R. A. Moreau ABSTRACT. The availability of winter barley in areas of the U.S. that are not well suited to grow corn, such as the mid‐Atlantic states, makes it a feedstock of choice for fuel ethanol production in those regions. Recently, it was found that the Elusieve process, the combination of sieving and air classification (elutriation or aspiration), was effective in fiber separation from corn flour prior to fermentation. The objective of this study was to determine the effect of the Elusieve process on the compositions of fractions from barley flour of a hulled (Thoroughbred) and a hulless (Doyce) barley variety. The barley grains were milled using a hammer mill and sieved into four size fractions. Air classification of the two largest size fractions using a commercial aspirator resulted in heavier fractions with higher starch, higher beta‐glucan, and lower neutral detergent fiber (NDF) contents. Hulls were preferentially carried into the lighter fractions, as signified by higher NDF contents of lighter fractions. Elusieve processing was more effective (higher separation factors) for the hulled variety than the hulless variety because higher hull presence caused increased carryover of hull into the lighter fractions for the hulled variety. The increase in beta‐glucan and starch contents in barley flour, by hull separation using the combination of sieving and air classification, may increase ethanol productivity and may be beneficial in fuel ethanol production from barley when using a process that converts both starch and beta‐glucans into fuel ethanol.

A lot of sources for this valuable ingredient have been identified. β-Glucan from these sources may be extracted to fulfill the ever growing demand for nutraceutical product. The industrialists may also exploit this situation by using this functional ingredient for developing new nutraceutical products. Such products may provide health benefits beyond basic nutrition. Numerous health benefits of β-Glucan are documented in scientific literature that may range from simple stomach problem to complex defense shield against cancer. This review focuses on potential sources of β-glucan, health implications, industrial applications and immunomodulatory effect of β-glucan.
