Several million tones of palm oil and palm olein are used annually in the world for frying. This paper will discuss their frying performances in three major applications - industrial production of potato chips/crisps, industrial production of pre-fried frozen French fries and in fast food outlets. In the first study, about four tones of potato chips were continuously fried 8 hours a day and fiv...

Cysteine-rich secretory proteins (CRISPs) are glycoproteins found exclusively in vertebrates and have broad diversified functions. They are hypothesized to play important roles in mammalian reproduction and in reptilian venom, where they disrupt homeostasis of the prey through several mechanisms, including among others, blockage of cyclic nucleotide-gated and voltage-gated ion channels and inhi...

Acrylamide, a chemical found in several carbohydrates rich foods processed at high temperatures, has been classified as potential human carcinogen; the need to minimize its presence diet cannot be overemphasized. This study was designed determine how acrylamide formation is influenced by potato varieties, processing temperatures and slice thickness crisp produced from established Kenyan varieti...

BACKGROUND/AIMS Recent research has shown associations between type of snack and wellbeing. These studies have been cross-sectional and the aim of the present research was to examine this topic using an intervention study. METHODS A between-subjects intervention study was carried out. Volunteers (100 students, mean age = 19.00 years; 27 male, 73 female) completed online questionnaires measuri...

Simple and rapid gas chromatographic (GC) method employing a high-resolution time-of-flight mass analyzer that enables direct analysis (no derivatization) of acrylamide in various heat-processed foodstuffs has been developed and validated. Co-isolation of acrylamide precursors such as sugars and asparagine, constituting the risk of results overestimation due to additional formation of analyte i...

The objective of this study was to evaluate sensory perception and consumers’ attitude liking products with different textures, crisps pâtés, added mealworm ingredient in amounts. By addition (Tenebrio molitor L.) the crisps, brittleness increased. However, an increase also increased darkness. Adding mealworms pâté reduced odour flavour vegetable cinnamon pepper as well oily texture. There no s...

Sweet potato is grown extensively from tropical to temperate regions and is an important food crop worldwide. In this study, we established detection methods for 17 major sweet potato viruses using single and multiplex RT-PCR assays. To investigate the current incidence of viral diseases, we collected 154 samples of various sweet potato cultivars showing virus-like symptoms from 40 fields in 10...
