  • Shrimp Cassava Cracker Puffed by Microwave Technique: Effect of Moisture and Oil Content on Some Physical Characteristics
    Kasetsart J. (Nat. Sci.) 47 : 434 - 446 (2013) Shrimp Cassava Cracker Puffed by Microwave Technique: Effect of Moisture and Oil Content on Some Physical Characteristics Thao Thanh Nguyen, Tuan Quoc Le and Sirichai Songsermpong* ABSTRACT Low-fat products have been proposed as a substitute for deep fried foods due to their improved shelf life and as a response to consumers’ health concerns with fried foods. Microwave puffing was used to puff shrimp cassava cracker (SCC) as a substitute for deep fried SCC in this study. The dried semi- product with various levels of initial moisture content (IMC) from 16 to 31.5% on a wet basis and added oil percentage (AOP) from 0 to 21% by weight were puffed by microwave heating for 1 min. Deep oil fried SCC was also used in comparison tests of hardness, volume expansion and sensory evaluation. It was clear that after microwave puffing, the hardness and volume expansion were significantly different at various levels of IMC and AOP. At the suitable IMC, the hardness of SCC without oil was noticeably higher than that of the sample with oil whereas its volume was significantly higher. The AOP had a negative correlation with hardness and volume expansion (%) at a highly significant level (P < 0.01). Hardness and volume expansion had a positive correlation at P < 0.05. The optimum level of IMC for volume expansion of SCC was 21.5% on a wet basis and an AOP at 15% and these could reduce the hardness comparable to the fried SCC. Although the volume expansion of microwave SCC was less than that of fried SCC, the sensory evaluation indicated that microwave heating at the optimum conditions was acceptable by the panelists as a new technique for puffed SCC product, especially in terms of avoiding high oil content.

  • A Cross-Cultural Study Between Chinese and Malay Undergraduates in a Private University
    Exploring Preferential Food Selection: A Cross-Cultural Study between Chinese and Malay Undergraduates in a Private University. Adila Alias Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy January 2019 Abstract Previous studies and cross-sectional surveys conducted in Malaysia have shown that the prevalence of obesity, diabetes and other non-communicable diseases (NCDs) are associated with poor diet practices. Overeating is contributing to the increasing prevalence of obesity and other NCDs among Malaysians. This study aims to investigate how environmental influences might impact food preferences between Malay and Chinese. Past research shows that ethnicity is related to differences in food-related beliefs, preferences and overall eating behaviour. To investigate how environmental factors might influence food preferences, a series of experiments were conducted using psychological paradigms. First, food consumption patterns using a Food Frequency Questionnaire (Chapter 2) between the two groups were compared. It was found that Malay participants consumed more spicy and savoury foods, and larger portions of both artificially and naturally sweet foods, such as fruits. Overall findings of the FFQ showed that Malay participants consume a higher level of energy intake compared to the Chinese participants, which is reflective of existing literature in Malaysia. Additionally, Malay participants showed a preference for wheat-based foods other than rice- which is staple food in traditional Malay cuisine. In contrast, Chinese participants showed a higher preference for traditional Chinese cuisine for everyday meals such as noodles and porridge. Preferential food selection was examined using a 2AFC method (Chapter 3). Malay participants selected spicy foods more than Chinese participants, and both groups made more preferential selections of savoury foods than they did for spicy foods.

  • Issues Facing the Traditional Fish Products Industry in Southeast Asia
    9th JIRCAS International Symposium 2002 - 'Value-Addition to Agricultural Products', I I 5-12/ Issues facing the traditional fish products industry in Southeast Asia Yeap Soon-Eong* and Tan Sen-Min Marine Fisheries Research Department, Southeast Asian Fisheries Development Centre, 2 Perahu Road, Singapore 718915 Abstract In Southeast Asia, traditional fish products represent a significantly large part of total fish utilization and are a major source of animal protein. As a result, these products are vitally important to food security, especially con­ sidering that most of them go to marginalized sectors of the population. Traditional fish products are generally of low value and intended mainly for the domestic market, although some specialty products are of high value and other products, such as fish sauce, are also now being exported. Issues facing the industry are: obtaining a reliable supply of raw materials-particularly good-quality raw materials; a lack of infrastructure; poor processing tech­ niques; a poor knowledge base; inadequate marketing; and a lack of food safety standards. To address these issues and improve traditional fish products, it is essential that the Southeast Asian countries promote and pre­ serve the production and use of these products, strengthen research and training activities, improve their market­ ing, and ensure that they meet food safety standards. However, in an effort to improve these products, their unique nature and their cultural and social importance should not be compromised. Introduction to the Marine Fisheries These are achieved through MFRD's three core activi­ ties, namely research and development, training and Research Department extension, and information services.

  • Shelf-Life Prediction of Indonesian Fish Cracker Fried with Mix Palm-Sesame Oil Using Accelerated Shelf-Life Test (ASLT)
    International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2015): 78.96 | Impact Factor (2015): 6.391 Shelf-Life Prediction of Indonesian Fish Cracker Fried with Mix Palm-Sesame Oil using Accelerated Shelf-Life Test (ASLT) Aldila Din Pangawikan1, Umar Santoso2, Suparmo3, Pudji Hastuti4 1Agricultural Technology Department, Faculty of Agriculture, Sriwijaya University Jl. Raya Palembang-Prabumulih Km.32 South Sumatra, Indonesia 2, 3, 4Food Science Department, Faculty of Agriculture Technology, Gadjah Mada University, Jl. Flora No 1 Bulaksumur, Yogyakarta, Indonesia Abstract: Cracker products, especially fish cracker was known to have short shelf-life and easily rancid due to oxidation deterioration. This research was aimed to extend fish cracker shelf-life by frying fish cracker using oil which made from mixing palm oil with sesame oil. Shelf-life was determined using Accelerated Shelf-Life Test (ASLT) with Arrhenius model based on thiobarbituric acid value (TBA). Experiment was conducted at temperature of 25° C, 35° C and 45° C until 15 days to follow oxidation level through TBA value. Results showed that ASLT method could be used to predict shelf-life of fried fish cracker with mix palm-sesame oil (90 : 10 v/v) that the main deterioration was due to oxidation reaction. The shelf-life of regular fish cracker (fried only with palm oil) was 48 days and those fried by mixed oil was 67 days. Frying fish cracker on mixed oil (palm-sesame) was able to extend shelf-life up to 19 days by reducing rancidity reaction. Keywords: Fish cracker, shelf-life, mixed oil, sesame oil, ASLT.

  • Dietary Guidelines for the Prevention of Obesity 1. Maintain Healthy Body
    Strategy for the Prevention of Obesity - Malaysia APPENDIX A1: Dietary Guidelines for the Prevention of Obesity Practising sensible and healthy dietary habits is the key to the prevention of excessive weight gain. The committee recommends the following dietary strategies for prevention of obesity among Malaysians:- 1. Maintain healthy body weight by balancing food intake with regular physical activity The first step to achieve healthy body weight is to practice healthy eating and be physically active. In most cases, overweight or obesity is a result of excess intake of calories and lack of physical activity over a period of time. The amount of energy needed to maintain a healthy body weight depends on an individual’s age, sex, physiological condition and physical activity level. 2. Eat a balance diet by enjoying a variety of foods The body needs foods as the source of energy and nutrients to grow, move, work, play, think and learn. However, no single food can supply all the nutrients in the amounts the body needs. Therefore, the best way to ensure that we meet the nutrients requirements is to eat a variety of foods within the recommended amounts according to the Malaysian Food Pyramid (Appendix A2). 3. Minimize fat in food preparation and choose foods that are low in fat Dietary fat is the major determinant of the energy density of diets. It imparts taste and flavour to foods enhancing their palatability, as well as promotes the absorption of fat- soluble vitamins. Despite its importance, excessive consumption of dietary fat can have adverse effects on health such as obesity and other non-communicable diseases.
