    A Randomized, Double Blind, Placebo-Controlled Human Clinical Trial On The Effects Of Sacha Inchi (Plukenetia Volubilis L.) Oil Supplementation In Hyperglycaemia, Hypertension And Hyperlipidaemia Patients
    (2024-07)
    Mhd Rodzi, Nur Anis Raihana
    The incidence of hyperglycaemia, hypertension and hyperlipidaemia (3Hs) have been prevalent in many developed and developing countries. Sacha Inchi oil (SIO) is a rich source of plant-based omega-3, 6, and 9 polyunsaturated fatty acids with promising health effects. However, the effects of SIO as complementary medicine among the 3Hs individuals are narrowly investigated. The present randomised, doubleblind, placebo-controlled human clinical trial aimed to explore the effects of SIO supplementation on (1) glycaemic control; (2) BPs; (3) lipid profiles; (4) inflammatory status; (5) oxidative stress; (6) circulating arterial calcification biomarkers; (7) anthropometry measurements; (8) quality of life; (9) mental health status; and (10) compliancy and tolerability among 3Hs patients. Fifty-four (n=54) 3Hs patients were recruited from Specialist Day Care Clinic, Pusat Perubatan USM Bertam, and randomised into two groups: the SIO group (n=27) (received 1000mg of SIO soft gel per day) or placebo group (n=27) (received 1000mg corn oil soft gel for 12 weeks). Fasting blood samples were collected at baseline and post week-12 to assess clinical and laboratory biochemical markers.

    Effects Of Pineapple Consumptions On Sensory Perceptions, Somatosensation And Taste Threshold
    (2023-02)
    Romli, Siti Rashima
    This study aims to determine the effects of pineapple consumptions on sensory perceptions, somatosensation, and taste threshold. The acceptance and consumption of pineapples among consumers were surveyed, and physicochemical and sensory acceptance of three pineapple varieties planted in the northern part of peninsular Malaysia (Moris, N36, and MD2) at various maturity stages were determined. The survey was conducted online with 167 respondents using a self-administrated questionnaire. A total of 28.1% of respondents refuse to eat pineapple because it causes an unpleasant feeling on the tongue (61.7%) and affects taste sensation (19.1%) after consumption. Although consuming fresh pineapple causes tongue irritation, consumers still prefer fresh fruit (61%) over processed pineapple due to its vitamin C, fibres, and bromelain enzyme, as well as its appealing flavour. Principal component analysis (PCA) plot with 80.16% variance shows that physicochemical properties such as lightness (L value), textures, titratable acidity, and vitamin C are important factors that influence consumer acceptance of the fruit. Pineapples harvested at Index 4 and Index 5 are suitable for fresh fruit consumption due to the texture and sensory acceptance of the fruit. Moris and N36 pineapples are nearly identical (>80% similarity) in terms of physicochemical properties and consumer acceptance, whereas MD2 has distinct organoleptic qualities such as being sweeter, less acidic, higher in vitamin C and more aromatic compared to Moris and N36.

    Reduction Of Sulphate In Waste Recycle Aggregate Using Bacillus Subtilis
    (2018-07)
    Abdul Aziz, Nurhanim
    Waste concrete aggregate (WCA) is highly potential to be re-utilised as a recycled material as it is applicable to numerous functions. Attached cement paste on WCA surface has limited the potential WCA to be recycled as a part of raw construction materials. Low density, high in water absorption and sulphate content are identified as the major contributing factors for this limitation. The sulphate content in delayed ettringite formation (DEF) from high water absorption of attached cement paste leads to DEF expansion and forms a micro-crack, causing a mass loss and affects the mechanical strength (compressive strength) of the concrete.

    Characterization Of Carbohydrate And Protein Accumulation In Oil Palm Trees
    (2018-09)
    Natra, Joseph Stalin
    This study characterized the accumulation of non-structural carbohydrate and protein in the oil palm trees. The starch and sugar are the main constituent contained in non-structural-carbohydrate. In this research, the starch and sugar accumulation in standing oil palm trees are characterized based on different growth conditions, then further analysed based position along the oil palm stem and influence of the weather fluctuation. The effect of storing on non-structural carbohydrate and protein content based on height in felled oil palm trunk also has been characterized. In the study on standing oil palm trees, eight oil palm trees was selected and divided equally into two different groups which are Non-Fruit Removal Trees (NFRT) and Fruit Removal Trees (FRT).

    Effects Of Different Gelling Agents And Puree Content In The Preparation Of Red Pitaya Fruits (Hylocereus Polyrhizus) Gummy Candy
    (2015-02)
    Romli, Siti Rashima
    Gummy fruit candy based on red pitaya fruit iHylocerens polyrhizusi was developed using high-methoxyl pectin (HMP) and fish gelatin (FG) as gelling agents. Different types of gummy candy were prepared based on various formulations using two concentrations (20 and 25 %, w/w) of red pitaya puree (RPP) and different gelling agent to water ratios (pectin/water
