Determination of nutritional value of tachypleus gigas (horseshoe crab)

Horseshoe crabs are marine arthropods of the family Limulidae, suborder Xiphosurida, and order Xiphosura[1]. Horseshoe crabs superficially resemble crustaceans but belong to a separate subphylum, Chelicerata, and are closely related to arachnids

U-Module and readpen

U-Module and ReadPen is a combination of module with read pen which is meant for university students to read book/ module anytime with a built in speaker on the pen. U-Module and ReadPen provides definition (synonym) and also translation of the sentences into several languages. For example, from English to Malay. The most interesting part of U-Module and ReadPen is that it starts the narration audio and translation from anywhere the consumer want, by just pointing the pen on any sentences in the textbook

Various Impact Resistance Capabilities of Tapioca Starch Based Shear Thickening Fluid (STF)

STF is a non-Newtonian flow behaviour often observed in concentrated colloidal dispersions characterized by significant, sometimes discontinuous increase in viscosity with increasing shear stress. Examples are concentrated particle colloidal suspensions such as photographic dies, paints, coatings and lubricants. When such fluid is subjected to a high-enough shear stress, it can lead to a rapid, sometimes discontinuous, increase in viscosity. The change in viscosity is due to the change of molecular arrangement structure in the colloidal suspension which usually will change from disordered liquid to ordered liquid crystals. Triangle Ternary Phase Diagram can be classified as a diagram that represents the equilibrium between the various liquid crystal (LC) phases that are formed between three components

Trace elements in market vegetables of Kuantan, Pahang: A preliminary estimate of dietary exposure

A pilot study was conducted to investigate the concentrations of ten trace elements: Copper (Cu), iodine (I), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se), zinc (Zn), arsenic (As), cadmium (Cd) and lead (Pb) in nine ready-to-eat market vegetables collected from Kuantan, Pahang. Samples of vegetables were obtained from a local market, acid-digested using open digestion method and then analysed for elements using Inductively Coupled Plasma - Mass Spectrometry (ICP-MS). The mean concentration of essential elements decreased in the following order: Mn>Zn>Mo>Cu>I>Ni>Se, with individual concentrations ranging from below detection limit (bdl) to 207 mg/kg dw. Cadmium, a non-essential element, was detected in 8 samples at a mean concentration of 0.06 mg/kg dw, while Pb and As were not detected (bdl) in all samples. The estimated daily dietary intake (EDI) as well as the potential health risk associated with vegetable consumption were calculated. Hazard quotient (HQ) values less than one were obtained for both children and adults, indicating that consumption of these vegetables poses low risk to health

Determination of proximate composition of Malaysian horseshoe crab (Tachypleus gigas)

This study was conducted to investigate proximate content of horseshoe crab (Tachypleus gigas) in Malaysia. To date, there has been little agreement on what the nutrition value of horseshoe crab is and how it will benefit the consumers. The samples were divided by two parts, which are roe and muscle. The Tachypleus gigas was cleaned of foreign materials and impurities manually by human hand. The samples were ground into flour and sieved through 50 μm sieve and were packaged in airtight plastic bags prior to analyses. The horseshoe crab was analyzed for its proximate composition of different body parts. The results showed that the roe and muscle of Tachypleus gigas contained moisture (50.45 % and 73.67 %), ash (0.41 % and 2.72 %), crude proteins (38.24 % and 14.62 %), crude fats (9.30 % and 8.09 %), carbohydrates (1.67 % and 0.91 %) and energy (241.42 Kcal/100 g and 134.43 Kcal/100 g), respectively. This shows that roe has better nutrition content since it has higher protein, fat and carbohydrate content, which are the main energy-providing nutrient. Overall, the proximate content of Tachypleus gigas was nearer to the shellfish rather than the finfish and can be considered as a good nutrition source

Discovery of urinary biomarkers of seaweed intake using untargeted lc–ms metabolomics in a three-way cross-over human study

Seaweeds are a marine source rich in potentially bioactive components, and therefore have attracted attention since the middle of the twentieth century. Accurate and objective assessment of the intake of seaweeds to study their health effects is hampered by a lack of validated intake biomarkers. In this three-armed, randomized, cross-over study, an untargeted metabolomics approach was applied for discovering novel intake biomarkers. Twenty healthy participants (9 men and 11 women) were provided each of three test meals in a randomized order: 5 g of Laminaria digitate (LD), 5 g of Undaria pinnatifida (UP), or a control meal with energy-adjusted pea protein. Four urine samples and a 24 h pooled urine were collected along with blood samples at seven time-points. All samples were profiled by LC-ESI-QTOF-MS and the data were analyzed by univariate analysis and excretion kinetics to select putative intake biomarkers. In total, four intake biomarkers were selected from urine samples. They were identified as hydroxyl-dihydrocoumarin at Level III, loliolid glucuronide at level I, and isololiolid glucuronide at level II, while the last one remains unknown. Further identification and validation of these biomarkers by a cross-sectional study is essential to assess their specificity and robustness

Chemical composition and physicochemical properties of red seaweed (Kappaphycus alvarezii) and brown seaweed (Sargassum polycystum) from Sabah, Malaysia

The proximate composition, amino acid composition and some physico-chemical properties of two type of seaweeds Kappaphycus alvarezii and Sargassum polycystum which widely cultivated in Sabah, Malaysia were investigated. S. polycystum showed the highest level of protein and crude fibre with 11.69% and 39.863% dry weight, respectively. Minor component was fat 0.12-0.13% in both seaweeds. As for the physicochemical properties of the seaweeds, their swelling capacity (SWC) ranged from 13.33 to 35.83 mL/g while water retention capacity (WRC), and oil retention capacity (ORC) ranged from 8.18 to10.59 g/g dry weight and 2.68 to 3.32 g/g dry weight, respectively. SWC and ORC of K. alvarezzi was higher than S. polycystum (p<0.05). Both seaweeds contained high amounts of minerals and balanced amino acid profiles. This study suggested that K. alvarezzi has high nutritional value which could be potentially used as ingredients in human food application

Application of different fruit peels powder as an organic fertilisers for the effective growth of water spinach (Ipomoea aquatica)

Macronutrients such as nitrogen (N), phosphorus (P) and potassium (K) are usually found in fertilizers which is essential to plant growth and development. The study reports on the utilization of different fruit peels as an organic fertilizer for the effective growth of water spinach (Ipomoea Aquatica). Each fruit peels of pineamle, banana and mango were collected separately from local fruit vendors. The fruit peels were cleaned, dried, and then grinded into powder individually. The chemical composition of fruit peels powder was analysed by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and CHNOS analyser which NPK concentration was determined. Among three analysed fruit peels, results demonstrated that banana peels powder showed the highest concentration of K and N, which consists of 26557.86 mg/L and 1.61%, respectively. Besides that, electrical conductivity measurement and water absorption capacity of fruit peels powder was studied. Plants were grown under vary amount of fruit peels powder treatments (mango, banana, and pineapple peels application), as well as control treatments (no fertilizer application). Plant height and number of leaves per plant were analysed to investigate the effect of fruit peels powder treatment on plant growth. The application of 3 g pineapple peels powder gave the better performances in all water spinach growth parameters with mean maximum plant height of 20.83±3.01 cm, number of leaves per plant of 9 was recorded. Hence, it can be concluded that 3 g pineapple peels powder can efficiently improve the utilization efficiency of fertilizers in agricultural production

Physicochemical, physical characteristics and antioxidant activities of three edible red seaweeds (Kappaphycus alvarezii, Eucheuma spinosum and Eucheuma striatum) from Sabah, Malaysia

Kappaphycus alvarezii (KA), Eucheuma spinosum (ESp) and Eucheuma striatum (Est are tropical red seaweeds taken from Kunak, Sabah, contain essentials source of bioactive compounds to produce variety of functional foods. This study was intended to investigate the physicochemical, physical properties and antioxidant activities related to these edible seaweeds. Physicochemical properties value of swelling capacity (SWC) and oil retention capacity (ORC) in KA species showed the highest value (p<0.05) compared to ESp and ESt, and water retention capacity (WRC) in ESp species was significantly different than KA and ESt (p<0.05). As in physical properties, ESp exhibited higher in moisture content and opacity than KA and ESt. KA showed the highest water solubility (p<0.05) which associated to its carrageenan compound. The antioxidant activities; DPPH and TEAC assay with total phenolic content (TPC) of three seaweed species indicated that KA displayed the highest TPC (19.17±0.04 mg GAE/g DW) and the lowest radical scavenging activity in both TEAC and DPPH assays. Hence, the findings disclose the physical and physiochemical properties and antioxidant values of these seaweeds application as new information and potential antioxidant sources in foods manufacturing commodities
