Authors:Zhaowen Mo; Haowen Luo, Wu Li, Yuzhan Li, Hua Tian, Shenggang Pan, Haidong Liu, Meiyang Duan, Xiangru Tang Abstract: Fragrant rice is popular globally due to its desirable grain quality and strong fragrance. 2-Acetyl-1-pyrroline (2AP) is believed to be one of the key aromatic compounds found in fragrant rice. The present study investigated the differential 2AP concentration in inferior and superior spikelets of fragrant rice. Results showed that inferior spikelets produced higher aroma than superior spikelets, but opposite trend was observed in grain yield. A significant positive correlation was observed between grain yield and contribution ratio to yield, number of grains/m2, filled number of grains/m2, percentage of filled grains, and total nitrogen content in grains. Besides, 2AP content at different panicle positions showed a significant negative relationship with contribution ratio to yield but a significant positive correlation with moisture content. The findings demonstrated that it was feasible to improve fragrance and maintain grain yield by reducing the difference between superior and inferior spikelets during grain filling period. The results of the study revealed fragrance in grains in relation to superior and inferior spikelets in fragrant rice panicles. PubDate: Fri, 01 Dec 2023 00:00:00 +000
Authors:Gülderen Kurt Kaya; Özlem Emir Çoban, Reşit Bilici Abstract: Marinated anchovies are of economic importance in Turkey. However, natural antioxidants affecting quality of marinated anchovies are rarely addressed. The purpose of this study is to compare olive oil and rosehip sauce as fillers in anchovy marinades. The study investigated the effects of rosehip sauce on the quality of marinated anchovies stored at 4°C. Anchovy were marinated with 4% acetic acid and 12% NaCl, put into plastic jars, filled with either olive oil or rosehip sauce and stored at 4°C. Changes in sensory attributes were determined during the process, and the following chemical parameters were monitored: total phenolic content (mg/100 g GAE), total volatile basic nitrogen (mg/100 g), pH, peroxide value (meq/kg) and thiobarbituric acid (mg MDA/kg). Values of total volatile basic nitrogen (TVB-N), peroxide value (PV) and thiobarbituric acid (TBA) increased during the storage. Higher values of TVB-N, TBA and PV were found in samples with olive oil than those with rosehip sauce. Samples with rosehip sauce demonstrated better oxidative stability. Rosehip sauce samples had higher appearance, odor, color and texture scores than olive oil samples. PubDate: Tue, 21 Nov 2023 00:00:00 +000
Authors:Sunisa Siripongvutikorn; Jinattita Thantrirat, Nattawut Rampoei, Praewa Banphot Abstract: Fresh Liang leaves, a local vegetable of Southern Thailand, were dried, seasoned, and fortified with different ratios of dried shrimp and sesame seeds at 1%–5% for making a rice topping product (Furikake) named as F1-F5. The F5 obtained the highest consumer acceptability with high calcium and phosphorus contents at 4,299.45 mg/kg and 3,436.32 mg/kg, respectively. Total phenolic content and DPPH radical scavenging antioxidant activity of F5 were 2,575.22 µg GAE/g DW and 676.99 µg TE/g DW, respectively. Total chlorophyll and carotenoid contents were 11.38 mg/g DW and 3.52 mg/g DW, respectively. An increment of aw and moisture content (p < 0.05) of the F5 kept at higher temperature storage was noticed, and a reduction of L* value under all storage conditions was noticed.

Authors:Yuridia Bautista-Martínez; Lorenzo Danilo Granados-Rivera, Jorge Alonso Maldonado-Jáquez, Pablo Arenas-Báez Abstract: This study aimed to investigate the effect of palmitic acid, added in the diets of finishing male sheep, affecting productive variables, carcass quality and meat. A total of 21 male sheep, cross of the Dorper and Pelibuey breeds, were used and divided into three treatments: control (CON), comprising sheep fed with the base diet; PA3 treatment, in which the diet included 3% palmitic acid; and PA6 treatment, in which the diet included 6% palmitic acid. The addition of 3% palmitic acid in the diet improved productive variables, carcass quality, and modified the anti-oxidant capacity without affecting the physicochemical characteristics of the meat.

Authors:Miao Liang; Zeen Yang, Kejing Xu, Xiaolong Chen, Jinchu Yang, Wenzhao Liu, Sensen Zhao, Yongming Xu, Junsong Zhang Abstract: In this study, the release behavior and kinetic characteristics of eugenol from clove particles under different temperatures were investigated by using purge and trap and gas chromatography–mass spectrometry (P&T–GC-MS) method. The results showed that the established P&T–GC-MS method could efficiently determine eugenol content in clove particles. The high temperature could promote the release of eugenol in the early stages of heating, while low temperature delayed the time to reach the maximum ratio. Kinetic analysis showed that the release behavior of eugenol at different temperatures was consistent with the first-order release model. The release activation energy for eugenol was calculated as 58.29 kJ/mol by using the Arrhenius equation. PubDate: Tue, 24 Oct 2023 00:00:00 +000
Authors:Xinlai Dou; Mingshou Lv, Xuyang Ren, Yinuyan He, Guang Zhang, Ying Sun, Na Zhang, Fenglian Chen, Chun hua Yang Abstract: Wheat flour is very important for making frozen dough. This paper firstly conducted an analysis of the basic properties of six varieties of wheat flour from different places and found that the variety BDHhgwf is most suitable to make frozen dough. Texture profile analysis (TPA) has been implemented in the dough-based food industry, and the properties of frozen dough were firstly investigated in this study. The results showed during TPA determination process of frozen dough, the variation of test parameters have an influence on the final result to some extent. The use of TPA in assessing the properties of frozen dough is presented. The recommended test conditions are: pre-test speed 3.0 mm/s, test speed (TS) 1.0 mm/s, posttest speed 1.0 mm/s, and compression ratio (CR) 50%. In a word, in this test method, the variation coefficient of dough was smaller and the dough was destroyed less by the texture analyzer and can truly reflect the texture of frozen dough.

Authors:Wenfeng Han; Po Qiu, Li Zhang Abstract: A method for the determination of Nε-(1-Carboxymethyl)-L-Lysine (CML) in brewing soy sauce was developed using ultrahigh performance liquid chromatography-tandem mass spectrometry. A mixed cation exchange solid phase extraction cartridge was used for purification, while gradient elution of a hydrophilic interaction chromatography column was performed with a 0.1% formic acid aqueous solution-acetonitrile. The adding standard recovery rate of this method ranged from 86.94 to 92.61%, and the relative standard deviation (RSD) was between 3.69 and 6.18%. The limit of detection (LOD) was 0.038 ng/mL, and the limit of quantification was 0.127 ng/mL. The RSD values of the repeatability test and the parallel test were 3.44 and 6.56%, respectively. Using this method, the CML contents determined in eight brewing soy sauce samples were 3.16 ± 0.18 – 15.10 ± 1.19 µg/mL. This method is simple, accurate, sensitive, and precise, and it is an effective method for monitoring the CML content in brewing soy sauce. PubDate: Thu, 05 Oct 2023 00:00:00 +000

The current study explored age, sex, and chilling effects on 48 goat carcasses cut in half by halal standards and shifting one half immediately to a walk-in chiller at 0–4°C [rapid chilling (RC)] and the other half at 26 ± 2°C [delayed chilling (DC)]. Results showed that Warner Bratzler Shear Force (WBSF) was significantly affected by RC. Cooking loss and color (L*) parameters were significantly higher in young male animals. Chroma values were significantly higher in DC. In conclusion, DC enhances meat quality and tenderness. PubDate: Tue, 03 Oct 2023 00:00:00 +000
Authors:Ayman M. El-Anany; Sami A. Althwab, Raghad M. Alhomaid, Rehab F. M. Ali, Hassan M. Mousa Abstract: The main objective of the present investigation was to evaluate the nutritional and sensory impacts of mortadella supplemented with various levels of Spirulina (Arthrospira platensis) powder (SP). Spirulina powder was investigated for its chemical composition, energy value, micronutrient concentration (mg/100 g), and functional qualities. The total amount of carotenoids, phenolics, flavonoids and antioxidant activity were assessed in chicken breast flesh and SP. Different SP (0–5.0%) proportions were integrated to mortadella recipes. The formulated mortadella samples were investigated for their proximate composition, mineral content, total carotenoids, total phenolics, total flavonoids, antioxidant activity, and sensory properties. SP possesses proteins, carbohydrates, crude fiber, ash, and lipids at 63.70, 15.84, 7.60, 7.49 and 5.37 g/100 g of dry sample, respectively. Water absorption capacity (WAC) and oil absorption capacity (OAC) of SP were 1.77 g and 1.65 mL/g of the sample, respectively. The results of the current study revealed that the antioxidant activity and total phenolic content of SP were significantly higher than those of chicken breast by 71.29- and 15.38-fold, respectively. Crude protein content of the mortadella control sample (SP0) was 13.58%, which increased to 14.17%, 14.72%, 15.33%, 15.95% and 16.49% for mortadella samples enhanced with 1%, 2%, 3%, 4% and 5% SP, respectively. Calcium, phosphorus, potassium, sodium, magnesium, iron, zinc, and selenium contents in mortadella samples, partially replaced with 5% SP, were approximately 2.27-, 1.21-, 1.28-, 1.02-, 1.46-, 3.91-, 1.21- and 1.08-fold higher, respectively, compared to the control sample without SP addition. The highest levels of total carotenoids, total phenolics, total flavonoids and antioxidant activity were found in the mortadella samples integrated with 3%, 4% and 5% SP. In contrast, the control sample and those supplemented with 1% and 2% SP were absolutely low in these constituents. The highest results (8.06–8.07) for overall acceptance were observed in mortadella samples with 2% and 3% SP. PubDate: Mon, 02 Oct 2023 00:00:00 +000
