Enterolobium cyclocarpum leaves are less acceptable by ruminants due to their high contents of anti-nutritional factors. The effect of preserving Enterolobium cyclocarpum leaves as hay and silage or silage: hay combinations on the proximate, fibre fractions, anti-nutritional factors, minerals and vitamins compositions were investigated in this study. Six experimental treatments consisting of 100% fresh Enterolobium cyclocarpum leaves, 100% ensiled Enterolobium cyclocarpum leaves, 100% sun dried Enterolobium cyclocarpum leaves, 75% silage: 25% hay, 50% silage: 50% hay and 25% silage: 75% hay were formulated. Each treatment was replicated 3 times and analyzed for chemical composition. The crude protein content ranged from 14.70 – 22.05%, which significantly differed (p<0.05) across treatments with the highest value in the fresh leaves. The values for neutral detergent fibre ranged from 56.64 – 57.92 %, acid detergent fibre from 37.14 – 39.87 % and acid detergent lignin from 13.30 – 14.96 %, they all differed significantly (p<0.05) across treatments with highest values in the 100% ensiled treatment. Preservation as silage significantly (p<0.05) reduced the concentrations of tannin, phytate and hydrocyanic acid, while preservation as hay significantly (p<0.05) reduced the concentration of saponin. The mineral contents of the EC leaves preserved as silage, hay and silage: hay combinations (Treatments 2 - 6) compared favourably with the mineral contents of the fresh leaves (Treatment 1). Preserved EC leaves (Treatments 2 – 6) had significantly (p<0.05) higher concentrations of vitamin C (444.21 –657.60 mg/100g) than the fresh leaves (308.79mg/100g). Thus preservation of E. cyclocarpum leaves as silage or hay improved its chemical composition and reduced its contents of anti-nutritional factors.

The study aimed to evaluate the addition of banana blossom (12.5, 25, 37.5, and 50% w/w) on nutritional quality, histamine content, bacterial count, and sensory characteristic in the fish floss prepared from little tuna (Euthynnus affinis). The crude protein content, essential amino acids, lipid, and polyunsaturated fatty acids (PUFA) steadily decreased (p <0.05), while the crude fibre, carbohydrate, and ash components of the tuna floss, increased significantly (p <0.05) with increasing levels of banana blossom. The contents of protein, fat, ash, fibre, carbohydrate, and moisture ranged 28.13 – 30.27%, 14.79 – 18.02%, 4.45 – 5.68%, 2.6 – 3.5%, 27.81 – 31.01, and 16.45 – 17.39%, respectively, and most of them met the Indonesian National Standard. For essential and non-essential amino acids, the level varied about 102.82 mg.g-1 to 206.76 mg.g-1 and 79.71 mg.g-1 to 138.76 mg.g-1, respectively in the treated tuna flosses. Moreover, ranging 13.72 – 16.29% of PUFA was found in all treated flosses. The most significant effect was found in the histamine levels of the tuna flosses, especially in the 50% added floss sample. Moreover, bacterial counts and heavy metals content were lower than the maximum limits regulated by the Indonesian National Standard. For sensory evaluation, the banana blossom-added samples significantly increased (p >0.05) the acceptability score for all attributes assessed. Taken together, the tuna floss added with 37.5% of banana blossom may be potentially developed as a low-histamine tuna-based product with high ffibre andEPA+DHA, as well as highly acceptable for consumers.

Lentil (Lens culinaris Medikus) is a protein-rich cool-season food legume with an excellent source of protein, prebiotic carbohydrates, minerals, and vitamins. With climate change, heat, and drought stresses have become more frequent and intense in lentil growing areas with a strong influence on phenology, grain yield, and nutritional quality. This study aimed to assess the impact of heat and drought stresses on phenology, grain yield, and nutritional quality of lentil. For this purpose, 100 lentil genotypes from the global collection were evaluated under normal, heat, and combined heat-drought conditions. Analysis of variance revealed significant differences (p &lt; 0.001) among lentil genotypes for phenological traits, yield components, and grain quality traits. Under no stress conditions, mineral concentrations among lentil genotypes varied from 48 to 109 mg kg−1 for iron (Fe) and from 31 to 65 mg kg−1 for zinc (Zn), while crude protein content ranged from 22.5 to 32.0%. Iron, zinc, and crude protein content were significantly reduced under stress conditions, and the effect of combined heat-drought stress was more severe than heat stress alone. A significant positive correlation was observed between iron and zinc concentrations under both no stress and stress conditions. Based on grain yield, crude protein, and iron and zinc concentrations, lentil genotypes were grouped into three clusters following the hierarchical cluster analysis. Promising lentil genotypes with high micronutrient contents, crude protein, and grain yield with the least effect of heat and drought stress were identified as the potential donors for biofortification in the lentil breeding program.

Cookies are one of the food products that are popular with the public. The raw material for making cookies is wheat flour, which is still imported from abroad and year by year the number of imports from abroad continues to increase. Utilization of avocado seed flour will reduce the use of wheat flour and can also reduce waste from avocados. The main factor in fulfilling the quality of a product can be assessed based on the appearance of the product, the taste of the product, and the nutritional value of a product. This study aims to analysed the level of preference (taste, aroma, texture, and colour) of cookies through organoleptic tests. The design of this study used an experimental study using the RAL (Completely Randomized Design) method with two replications. Avocado seed flour substitution formulation in 4 treatments, namely control (P1), 30% (P2), 50% (P3) and 70% (P4). The research location is at the State University of Medan. The subjects (untrained panellists) of this study were 25 people. The data from the organoleptic test were analysed descriptively using the percentage of respondents' acceptance from each treatment level and to determine the effect of avocado seed flour substitution on the treatment, Kruskal Wallis statistical analysis was used. The results of this study indicate that the best formula for cookies with 50 percent substitution of avocado seed flour obtained an average value of 1.2 for taste, 0.3 for colour, 0.6 for texture, and for aroma 0.3 with a total value of 2, 4. Based on the results of the Kruskal Wallis test, it is known that there is a significant difference in perception seen from the level of preference for colour, aroma, taste, and texture of avocado seed flour cookies (p = 0.000).

In the present study effect of processing treatments viz. blanching and germination on the proximate composition of Pennisetum glaucum (pearl millet) was studied. Proximate composition was analysed by the standard methods determined according to Association of Official Analytical Chemists. Results indicated that moisture content increased significantly after processing treatments. Blanching resulted in non significant increase in ash content of pearl millet grains. The crude protein content of unprocessed pearl millet was 11.55%. The crude protein content of blanched pearl millet grains was 11.27%. Crude protein content of germinated grains was found to be 12.38% as in comparison to 11.55% in unprocessed and 11.27 in blanching treatment. Crude fat content of unprocessed (control), blanched and germinated pearl millet grains were 5.36, 5.09 and 4.55%, respectively. Fiber content increased significantly after blanching and germination processing treatments. Processing treatments not only effect the nutritional composition of pearl millet but also contribute towards enhancement of shelf life.

Objective: Ogi is a fermented cereal gruel produced from maize, sorghum or millet. The objective of the study was to investigate the effect of ginger and cinnamon on the proximate composition and sensory properties of corn ogi. Methodology: Ogi slurry was prepared from corn and fortified with 5% ginger, 5% cinnamon, 5% ginger: 5% cinnamon and 2.5% ginger: 2.5% cinnamon spices and 100% corn ogi as control. The samples were analyzed for proximate composition and sensory properties using standard methods. Results: The results obtained from this study indicated that there was an increase in the moisture, ash, protein and fat contents of corn ogi spiced with ginger and cinnamon and a decrease in carbohydrate content. These increases were observed to be significant (p<0.05) with corn ogi samples spiced with ginger than for cinnamon except for crude fiber which was higher in ogi spiced with cinnamon. Moisture content of the ogi samples ranged from 8.53-9.79%, crude protein 5.13-6.37%, ash 0.19-0.30%, crude fiber 0.29-0.81%, carbohydrate 78.93-81.64% and energy contents 387.77-391.98 kcal. The inclusion of cinnamon and ginger had no significant (p<0.05) effect on the sensory properties of the unsweetened spiced ogi samples. Mean scores obtained for unsweetened ogi samples were low. Upon sweetening with sugar, these scores were increased for all sensory attributes. Sensory evaluation of sweetened ogi samples showed that the control sample was more preferred for all sensory attributes and this was followed closely by sample ogi spiced with 5% ginger. Conclusion: This study recommends the use of ginger at 5% for the fortification of corn ogi which will result in ogi with sensory properties similar to 100% corn ogi. It also showed the potential of fortifying corn ogi with ginger and cinnamon, either singly or as a blend, to enhance the nutritional quality of corn ogi.
