Abstract. Objective: This study aimed to evaluate the effect of maternal consumption of flaxseed flour and oil on serum concentrations of glucose, insulin, and thyroid hormones of the adult female offspring of diabetic rats. Methods: Wistar rats were induced to diabetes by a high-fat diet (60%) and streptozotocin (35 mg/kg). Rats were mated and once pregnancy was confirmed, were divided into the following groups: Control Group (CG): casein-based diet; High-fat Group (HG): high-fat diet (49%); High-fat Flaxseed Group (HFG): high-fat diet supplemented with 25% flaxseed flour; High-fat Flaxseed Oil group (HOG): high-fat diet, where soya oil was replaced with flaxseed oil. After weaning, female pups (n = 6) from each group were separated, received a commercial rat diet and were sacrificed after 180 days. Serum insulin concentrations were determined by ELISA, the levels of triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined by chemiluminescence. Results: There was a significant reduction in body weight at weaning in HG (−31%), HFG (−33%) and HOG (44%) compared to CG (p = 0.002), which became similar by the end of 180 days. Blood glucose levels were reduced in HFG (−10%, p = 0.044) when compared to CG, and there was no significant difference between groups in relation to insulin, T3, T4, and TSH after 180 days. Conclusions: Maternal severe hyperglycemia during pregnancy and lactation resulted in a microsomal offspring. Maternal consumption of flaxseed reduces blood glucose levels in adult offspring without significant effects on insulin levels and thyroid hormones.

The study aimed at assessing effects of partial replacement (0–40%) of wheat flour with roasted flaxseed flour (RFSF) on the quality attributes of biscuits. Nutritional, antioxidative, volatile and sensory properties, as well as texture analysis and the contents of macroelements and microelement were studied. Increasing RFSF content in biscuits resulted in a significant increase (p < 0.05) in protein (from 8.35% to 10.77%), fat (from 15.19% to 28.34%) and ash (from 1.23% to 2.60%) while the hardness and spread factor of the biscuits decreased with the increased level of roasted flaxseed flour. Moreover, the addition of 40% RFSF registered a positive influence on the fibre content of the final baked biscuits, increasing its value about 6.7-fold than in the control sample. Total phenolic content, antioxidant activity and biscuits’ aroma volatile profile increased their amounts with RFSF addition. The nutritional, textural and sensorial results of the present study demonstrated that 25% RFSF could be added in the biscuits manufacturing without affecting the biscuits aftertaste, offering promising healthy and nutritious alternative to consumers.

The Difference

Abstract The difference between theoretical and empirical triglyceride content is a powerful tool to detect the presence of any vegetable oil in olive oil. The current drawback of the method is the separation between equivalent carbon number ECN42 compounds, which affects the reliability of the method and, hence, its cutoff limit. The determination of the triglyceride profile by liquid chromatography using propionitrile as the mobile phase has recently been proposed to improve their quantification, together with a mathematical algorithm whose binary response determines the presence or absence of hazelnut oil. Twenty-one laboratories from 9 countries participated in an interlaboratory study to evaluate the performance characteristics of the whole analytical method. Participants analyzed 12 samples in duplicate, split into 3 intercomparison studies. Statistically significant differences due to the experimental conditions were found in some laboratories, which were detected as outliers by use of Cochran's and Grubbs' tests. The relative standard deviations (RSD) for repeatability and reproducibility were determined following the AOAC Guidelines for Collaborative Studies. The analytical properties of the method were determined by means of the sensitivity (0.86), selectivity (0.94), and reliability (72) for a cutoff limit of 8 (probability 94).

Oil In Water Emulsion

This study investigates the antioxidant behaviors of a hazelnut tetrapeptide, FSEY (Phe-Ser-Glu-Tyr), in an oil-in-water emulsion. The emulsion was prepared with stripped hazelnut oil at a ratio of 10%. O/W emulsions, both with and without antioxidants (FSEY and TBHQ), were incubated at 37 °C. The chemical stabilities, including those of free radicals and primary and secondary oxidation productions, along with the physical stabilities, which include particle size, zeta-potential, color, pH, and ΔBS, were analyzed. Consequently, FSEY displayed excellent antioxidant behaviors in the test system by scavenging free lipid radicals. Both primary and secondary oxidation products were significantly lower in the FSEY groups. Furthermore, FSEY assisted in stabilizing the physical structure of the emulsion. This antioxidant could inhibit the increase in particle size, prevent the formation of creaming, and stabilize the original color and pH of the emulsion. Consequently, FSEY may be an effective antioxidant additive to use in emulsion systems.

ABSTRAKKemiri sunan (Reutealis trisperma (Blanco) Airy Shaw) dikenal sebagai tumbuhan yang berperan sebagai pestisida nabati yang belum banyak diketahui keampuhannya, sehingga perlu dilakukan pengujian untuk memperoleh informasi tentang keampuhan dari tumbuhan ini. Pengujian efektivitasnya dilakukan terhadap larva Crocidolomia binotalis Zell. penyebab kerusakan pada tanaman sawi. Percobaan dilaksanakan di Laboratorium Vertebrata, Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Padjadjaran, Jatinangor, berlangsung dari Maret sampai Mei 2019. Percobaan menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 5 ulangan. Perlakuan meliputi minyak kemiri sunan dengan konsentrasi 10%, 5%, 2.5%, 1.25% dan kontrol. Hasil penelitian menunjukkan minyak kemiri sunan berpengaruh terhadap larva Crocidolomia binotalis. Konsentrasi 10% dapat mengakibatkan mortalitas paling tinggi sebesar 100% pada 7 HSA. Selain toksik, minyak kemiri sunan juga dapat memperpanjang lama perkembangan larva, menghambat aktivitas makan (antifeedant), serta menurunkan berat kering larva dibandingkan dengan kontrol. Minyak kemiri sunan berpotensi sebagai alternatif pengendali hama yang ramah lingkungan karena dapat berperan sebagai pestisida nabatiKata kunci: Kemiri sunan, Crocidolomia binotalis, Pestisida nabatiABSTRACTReutealis trisperma (Blanco) Airy Shaw is know as a plant that acts as a vegetable pesticide that is not yet widely known for its efficacy, so testing is needed to obtain information about the efficacy of this plant. Effectiveness testing is carried out on Crocidolomia binotalis Zell. larvae causing damage to oil palm plants. The experiment was carried out in the vertebrate laboratory, the deparment of pest and plant diseases, the faculty of agriculture, the university Padjadjaran, taking place from March-May 2019. The experiment used the randomized design complete with 5 treatments and 5 replication. The treatments included oil Reutealis trisperma (Blanco) Airy Shaw with a concentration 10%, 5%, 2.5%, 1.25% and control. The result hazelnut oil affected the larva Crocidolomia binotalis Zell. 10% concentration can cause the highest mortality of 100% at 7 HAS. In addition to toxic, hazelnut oil prolong the development of larvae, inhibit feeding activity, and reduce the dry weight of larvae compared to controls. Hazelnut oil has potential as an alternative as an a alternative pest control that is environmentally friendly because it can act as a botanical pesticide.Keywords : Reutealis trisperma, Crocidolomia binotalis, Botanical pesticide
