This study was aimed at investigating the effect of ginger as natural antioxidant (NA) treatment in stabilizing poultry by-product meal. Poultry by-products meal (PBPM) were randomly prepared into four treatment groups (T1, T2, T3 and T4) and treated with 0, 750, 1250 and 1750 gram of ginger/100kg respectively and stored for 60 days. Microbial assessment and oxidative properties of PBPM was estimated fortnightly using total aerobiccount (TAPC), total coli-form unit count (TCC), peroxide value (POV) and thiobarbituric acid (TBA) test. Poultry by-product meal treated with 1750 gram of ginger/100kg presented the least oxidation for both TBAs (0.064 mg/g) and POV (0.4 mEq/kg) after the 60 days storage period. Both TAPC and TCC for all samples observed in this study are all below satisfactory levels with reference to the standard microbial load specification. It is concluded that ginger rhizome used as a natural antioxidant was effective in stabilizing poultry byproduct meal as it presented better microbial and antioxidant status at 1750 g/100kg.

Seventy two (72) sexed crossbred rabbits aged 6 months were used to determine the effect of ginger rhizome powder (GRP) supplementation on reproductive organ and serum sex hormonal characteristics of pubertal rabbits. The experimental rabbits were divided into 2 treatment groups comprising 36 males and 36 females. Each group was divided into 4 dietary treatments (BT1, BT2, BT3 and BT4 ) of 9 animals and replicated thrice with 3 animals per replicate in a completely randomized design (CRD). The animals were fed formulated diet containing 2900 Kcal ME kg-1 and 18% crude protein supplemented with GRP at the rate of 0, 5, 10 and 15 g kg-1 feed respectively. Rabbits in each dietary group were fed 50gms of Guinea grass leaf meal containing 27.6% CF (dry matter basis) occasionally as additional fibre sources. Feed and water were offered ad libitum and the study lasted for 10 weeks. Testosterone values of BT (5.83 ng mL-1) and BT (6.28 ng mL-1) and follicle stimulating hormone (FSH) levels of BT (1.15 mIU mL-1) were significantly influenced (p<0.05) by ginger rhizome powder. Bucks on BT3 and BT4 had lower luteinizing hormone (LH) level than the BT1 bucks. For the females, FSH and LH values ranged significantly (p<0.05) from 0.90 to 2.05 mIU mL-1 and 0.90 to 3.15 mIU mL-1 respectively. The 17â - estradiol and progesterone levels also ranged significantly (p<0.05) from 166.35 to 175.05 pg mL-1 and 15.45 to 16.80 ng mL-1 respectively. Ovarian weight of rabbit on BT was significantly (p<0.05) higher than those on BT1 but similar to those on BT2 and BT4 treatments. It was therefore concluded that the use of ginger rhizome powder in rabbit diets improved the weight of the ovary as well as enhances serum progesterone, estrogen and testosterone levels.

Purpose The purpose of this study was to study the effect of kiwifruit juice and tumbling in improving tenderness and to access antioxidant potential of kiwifruit juice. Design/methodology/approach Three treatment groups were made: Spent hen meat was subjected to still marination (SM) and tumbling marination (TM). This meat was used for preparation of whole muscle chicken nuggets and compared with control (without marination) nuggets (Con). These treatments were subjected to analysis of physicochemical characteristics, textural quality, lipid oxidation and sensory quality. Findings SM and TM exhibited higher moisture content and lower protein and fat content than Control SM and TM showed significant (p = 0.132) reduction in firmness from 5.1 to 2.3 and 1.2 Kg/cm2, respectively, and toughness from 14.1 to 6.2 and 3.3 Kg-sec/cm2, respectively, as observed by Warner-Bratzler shear and improvement in texture profile values. Sensory scores for texture, juiciness and overall acceptability were also better for SM and TM. Significant (p = 0.007) reduction was observed in lipid oxidation parameters of SM and TM. Thiobarbituric acid (TBA) values (on 0 day) for SM and TM were 0.18 and 0.15 as compared to 0.28 mg/kg of malonaldehyde for control. Peroxide values (PV) were also lower for SM and TM as 0.44 and 0.33, which were lesser than control (0.62 meq. peroxide/kg). The values for PV, TBA and free fatty acid increased with increase in storage period in all treatment groups. However, the antioxidant activity of kiwifruit juice persisted during whole storage period evidenced by lower values of lipid oxidation parameters for SM and TM than Control at each storage interval. Research limitations/implications Further research may be carried out to compare the tenderizing potential of kiwifruit juice with other plant proteases and physical tenderizing techniques. Spent hen meat utilization can be done with greater efficiency by using such techniques in meat caterings. Practical implications Spent hen meat utilization can done with greater efficiency by using such techniques in meat caterings. Originality/value Marination with kiwifruit juice improved the quality characteristics of chicken nuggets made from spent hen meat without altering its sensory quality. Tumbling was found to be beneficial in enhancing the tenderizing effect. Therefore, marination with kiwifruit juice can be used as a processing technology to use spent hen meat in preparing value added products.

Purpose The purpose of the study was to explore the possibility of utilization of epigallocatechin-3-gallate (EGCG) as a novel preservative in cheese. EGCG has strong antioxidant and antimicrobial properties and may be commercially exploited as a natural antioxidant and preservative in cheese like products which are highly susceptible to lipid oxidation. Design/methodology/approach The study was conducted to evaluate the possibility of using EGCG as a natural antioxidant and preservative in cheese. Kalari, a hard and dry cheese, was used as a model and treated with different concentrations of EGCG (0, 0.05 and 0.10 per cent) and aerobically packaged within low-density polyethylene pouches and assessed for oxidative stability and storage quality under refrigerated (4 ± 1°C) conditions. Findings EGCG showed a significant (p < 0.05) effect on the lipid oxidative stability as the treated products exhibited significantly (p < 0.05) lower thiobarbituric acid reactive substances (milligram malonaldehyde/kg) values. A significant (p < 0.05) effect was also observed on the microbiological characteristics of the products, as treated products showed significantly (p < 0.05) lower values for total plate count (log cfu/g), psychrophilic count (log cfu/g), yeast and mould count (log cfu/g) and free fatty acid (% oleic acid) values. Coliforms (log cfu/g) were not detected throughout the storage period. Significantly (p < 0.05) higher scores were observed for various sensory parameters of the treated products. EGCG successfully improved the oxidative stability and storage quality of Kalari. Originality/value The results suggest that EGCG might be useful to the dairy industry as an efficient alternative to synthetic antioxidants and preservatives.

This study aimed to investigate the effectiveness of 2,4,4′-trihydroxychalcone as a natural antioxidant on the oxidation of sunflower oil during an 88-day storage period and to compare its strength with the synthetic antioxidant butylated hydroxytoluene (BHT). Seven groups of the sunflower oil samples were prepared: pure oil (control), oil treated with different concentrations (100, 500, and 1000 ppm) of 2,4,4′-trihydroxychalcone, and oil treated with different concentrations (100, 500, and 1000 ppm) of BHT. Specific parameters, namely, the peroxide value (PV), acid value (AV), p-anisidine value (p-AnV), thiobarbituric acid reactive substance (TBARS) value and total oxidation (TOTOX) value were used to assess the extent of the deterioration of the oil by estimating the primary and secondary oxidation products. The results showed that 2,4,4′-trihydroxychalcone effectively decreased the production of the primary and secondary oxidation products of sunflower oil during storage, as indicated by reductions in the PVs, AVs, p-AnVs, TBARS values and TOTOX values of the sunflower oil. When compared to BHT, 2,4,4′-trihydroxychalcone showed either a similar or stronger effect in inhibiting the primary and secondary oxidation products. These findings suggest that, 2,4,4′-trihydroxychalcone is a suitable natural alternative to synthetic antioxidants to improve the oxidative stability of sunflower oil.

The present study was undertaken to evaluate the effect of different levels of tulsi leaf extract on fresh and preserved beef meatballs. Four types of beef meatballs were formulated for this purpose. Meatballs were made with 0 (control), 0.1, 0.2 and 0.3% tulsi leaf extract, respectively and preserved at-20°C. Quality and safety evaluation of meatballs were determined by sensory, physicochemical, biochemical and microbiological tests. The analyses were conducted at 0, 15th, 30th and 60th days of interval. Considering CP, tenderness, juiciness, overall acceptability, cooking loss, Free Fatty Acid (FFA), Per oxide Value (POV) and Thiobarbituric Acid Reactive Substances (TBARS) value, it can be concluded that tulsi leaf extract @ 0.1, 0.2 and 0.3% can be used in the formulation of beef meatball. In case of sensory evaluation 0.2% tulsi leaf extract is appreciated but on the basis of nutrient quality, physicochemical properties, biochemical analysis and microbial analysis 0.3% tulsi leaf extract is more satisfactory as a source of natural antioxidant than that of other treatment groups. Therefore, it may be concluded that 0.3% tulsi leaf extract can be added as a functional ingredients in beef meatball.J. Bangladesh Agril. Univ. 16(2): 260-265, August 2018

One problem for developing small white ginger (Zingiber officinale var. amarum) is theavailability of high quality rhizome seeds in right quantity and time. Seed rhizome will sproutquickly, and its quality will decreased in immature seed rhizome and in not good storage conditions.The main objective of the experiment was to study the best storage room conditions for storagerhizome seeds of small white ginger. The experiment was conducted in seed laboratory and storageroom of Research Institute for Medicinal and Aromatic Crops Bogor. The experiment wasconducted by randomized complete design with nine different storage, 3 replication and 25 sampleseach treatment. The treatments are 1) rhizome seeds storage in room temperature (control),(2)rhizome seeds storage in AC room (16–240C),(3) rhizome seed soaked in paclobutrazol 1000 ppmfor 4 hours then seeds storage in room temperature ( 4) put rhizome seeds in rack and cover bystraw, storage in room temperature (5) rhizome seed storage on straws in the greenhouse ( 6)rhizome seed storage in the greenhouse without straw ( 7) rhizome seed soaked in water during 1hour every month then dried naturally in 300C and storage in AC room (8) rhizome seed soakedin paclobutrazol 1000 ppm for 4 hour then storage in AC room ( 9) put rhizome in wood box andcover by rice straw and husk. Variables observed include moisture contents of ginger seed, lostweight of seed and germination percentage of rhizome seeds at the end of storage period. The resultof experiment indicated that the moisture content and weight rhizome seeds decrease after 2 months. After four months storage period, moisture content was still high above 80 %, exceptrhizome seeds in under ground. The rhizome seeds that store in AC room showed the bestperformance and thus, this treatment can be recommended for storage of small white gingerrhizome seeds for 4 months. The low moisture content (< 80%) of rhizome small white ginger seedswill decreased its viability.Keywords: Zingiber officinale var. amarum, seed, storage, viability

Insulin resistance (IR) may be associated with oxidative stress and leads to cardiovascular disorders. Current research focuses on interplay between insulin-resistance indices and oxidant-antioxidant markers in elderly individuals with or without insulin-resistance. The assessment involved anthropometric data (weight, height, BMI, percentage of body fat (FAT)) and biochemical tests (glucose, lipids, serum insulin and plasma oxidant-antioxidant markers: Thiobarbituric Acid-Reacting Substances (TBARS), Cu,Zn-superoxide dismutase (SOD-1) and total antioxidant status). Insulin resistance index (IR) assuming a cut-off point of 0.3 allows to divides groups into: insulin sensitive group (InsS) IR < 0,3 ( n = 35, median age 69.0 years) and insulin-resistant group (InsR) IR ≥ 0.3 ( n = 51, median age 71.0 years). Lipids and antioxidant defense system markers did not differentiate the investigated groups. In the InsR elderly group, the FAT was increased ( P < 0.000003) and TBARS ( P = 0.008) concentration decreased in comparison with InsS group. A positive correlation for SOD-1 and total antioxidant status ( P < 0.05; r =  0.434) and a negative correlation for TBARS and age ( P < 0.05 with r = −0.421) were calculated in InsR individuals. In elderly individuals, oxidative stress persists irrespective of insulin-resistance status. We suggest that increased oxidative stress may be consequence of old age. An insulin action identifies those at high risk for atherosclerosis, via congruent associations with oxidative stress and extra- and intra-cellular antioxidant defense systems. Thus, we maintain that insulin-resistance is not the cause of aging. Impact statement Insulin resistance is associated with oxidative stress leading to cardiovascular diseases. However, little research has been performed examining elderly individuals with or without insulin-resistance. We demonstrate that antioxidant defense systems alone is not able to abrogate insulin action in elderly individuals at high risk for atherosclerosis, whereas the combined oxidant-antioxidant markers (thiobarbituric acid-reacting substances (TBARS), Cu,Zn-superoxide dismutase (SOD-1), and total antioxidant status (TAS)) might be more efficient and perhaps produce better clinical outcome. In fact, a decrease in oxidative stress and strong interaction between antioxidant defense can be seen only among insulin-resistant elderly individuals. This is, in our opinion, valuable information for clinicians, since insulin-resistance is considered strong cardiovascular risk factor.
