The chemical and physical characteristics of Malaysian palm kernel and its products are discussed in this article. The main products derived from palm kernel are palm kernel oil, palm kernel olein and palm kernel stearin whereas the by-products are palm kernel meal and palm kernel fatty acid distillate. The major composition of the kernel is oil (49%), followed by carbohydrate (26.1%), protein ...

Apricot kernel oil is a rich source of MUFA and PUFA, including mainly oleic (about 70%) and linoleic acids, respectively. In addition, apricot kernel oil could be considered as a good source of bioactive compounds such as tocopherols and phytosterols consisting mainly of the γ-isomer and βsitosterol, respectively. Given to its high content of oleic acid, apricot kernel oil is considered as a h...

Considering the possibility of the harmful side effects of synthetic antioxidants, it is necessary to substitute the synthetic antioxidants by the natural ones, the antioxidants that have been consumed by man for years. The mango seeds were washed and air dried and the kernels were removed manually from the seeds. Mango seed kernel oil was extracted by hexane using soxhlet extraction apparatus....

BACKGROUND The purpose of this study was to select appropriate surfactants or blends of surfactants to study the ternary phase diagram behavior of newly introduced palm kernel oil esters. METHODS Nonionic surfactant blends of Tween(®) and Tween(®)/Span(®) series were screened based on their solubilization capacity with water for palm kernel oil esters. Tween(®) 80 and five blends of Tween(®) ...

this study was done to evaluate quality properties of pistacia atlantica var mutica (bene) nuts under deferent storage conditions and packaging. at the zero time, sfa and total tocopherol (tt) and total phenolic (tp) compounds were 6.8 and 725.28 and 40.1 mg per kg oil, respectively. some quality properties (peroxide value (pv), conjugated diene value (cdv) and carbonyle value (cv)) showed that...

This study compared the profiles of fatty acids, phytosterols, and polyamine conjugates in conventional commercial corn oil extracted from corn germ and in two ‘‘new-generation’’ corn oils: hexane-extracted corn fiber oil and ethanol-extracted corn kernel oil. The fatty acid compositions of all three corn oils were very similar and were unaffected by degumming, refining, bleaching, and deodoriz...

BACKGROUND AND AIMS Previous studies have reported effects of pollen source on the oil concentration of maize (Zea mays) kernels through modifications to both the embryo/kernel ratio and embryo oil concentration. The present study expands upon previous analyses by addressing pollen source effects on the growth of kernel structures (i.e. pericarp, endosperm and embryo), allocation of embryo chem...

We evaluate three link functions (square root, logit, and copula) and Matérn kernel in the kernel-based estimation of reflectance spectra of the Munsell Matte collection in the 400-700 nm region. We estimate reflectance spectra from RGB camera responses in case of real and simulated responses and show that a combination of link function and a kernel regression model with a Matérn kernel decreas...

Let K be a smooth Calderón-Zygmund convolution kernel on R and suppose we are given a function a ∈ L∞. The two-dimensional commutator Tf(x) = ∫ K(x− y)f(y) ∫ [x,y] a(z) dz dy was shown to be bounded on L(R), p > 1 by Christ and Journé [1]. In this article, we show that this operator is also of weak type (1, 1).
