Kernel Meal

This study aimed to investigate the effect of solid-state fermentation on the nutritional composition of cottonseed meal (CSM), sunflower meal (SFM) and hazelnut kernel meal (HKM). In this study, each feedstuff was divided into two treatment groups (unfermented and fermented) with five replicates. Nutritional changes in the feedstuffs were determined by analyzing crude protein, ether extract, ash, crude fiber, neutral detergent fiber, acid detergent fiber contents. Solid-state fermentation had effects on the nutritional composition in all feedstuffs. The best improvement in nutritional quality was obtained from the HKM with increasing the crude protein and decreasing the structural carbohydrates content. Fermented HKM can be considered as an alternative protein feed for soybean meal considering the nutritional composition.

This study aimed to investigate the effect of solid-state fermentation on the nutritional composition of Agaricus bisporus mushroom stalk and cap. Four homogenous test samples were prepared from the fermented mushroom stalk (Fermented MS), unfermented mushroom stalk (MS), fermented mushroom cap (Fermented MC), and unfermented mushroom cap (MC); each was independently analyzed in triplicates, providing a total of 12 independent measurements of all treatments. Nutritional changes in the mushrooms were determined by analyzing crude protein (CP), ether extract (EE), crude ash (CA), crude fiber (CF), hemicellulose, neutral detergent fiber (NDF), acid detergent lignin (ADL), and acid detergent fiber (ADF) contents. The best improvement in nutritional composition was obtained from the MS with increasing the crude protein (35 %). The results related to other parameters are similar among all the treatments, except for CF. To conclude, the fermented MS can be considered as an alternative protein resource in animal nutrition.

The fermentation indicators and compositional quality of food made with the solid-state fermentation of potatoes and carrots were analyzed in order to make use of foods that do not meet the requirements of consumers. Three treatments were formulated by varying the potato:carrot ratio mixed with wheat bran and corn cabbage. A microbiological analysis was performed at 0, 24 and 96 hours; the pH, crude protein (PC), ash (CZ), ethereal extract (EE), crude fiber (FC), neutral detergent fiber (FDN) and acid detergent fiber (FDA) were monitored at 0, 24, 48, 72 and 96 hours. Acidification was observed between sampling at 0 and 96 hours, with values ranging from 5.68 to 4.46, 5.73 to 4.46 and 5.69 to 4.33 for the treatments with the potato:carrot ratios 20:20, 25:25 and 30:30, respectively. Similarly, a reduction of dry matter (P<0.05) and PC increase (P<0.05) were observed from 20.1 to 26.7%, 21.1 to 27.1% and 25, 4 to 27.9%, respectively for the previous ratios. No significant statistical difference was found in the variables CZ, MS, EE, FDN, FDA or FC; a significant growth of lactic acid bacteria (LAB) counts and an absence of Salmonella were evident. The proportionality in the PC increase with the potato:carrot ratios was viable with the increase of the drying material, such as wheat bran and corn cabbage.

The study was aimed to improve the nutritional composition of nettle (Utrica dioica L.) having positive effects on animals by solid-state fermentation. Aspergillus niger was used as a inoculant in fermentation of nettle. Before and after fermentation, crude protein (CP), ash, ether extract (EE), nitrogen-free extract (NFE), crude fiber (CF), hemicellulose (HC), neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL) contents of nettle were determined. The ash, NFE and HC content of nettle were increased by fermentation. However, A. niger decreased the CF and EE in nettle. The results showed that solid-state fermentation with A. niger can be used to improve the nutritional composition of nettle.

Harvesting Stage

Productivity of bulb onions (Allium cepa L.) is largely constrained by postharvest losses. There are several postharvest strategies applicable to onions, but they are mostly applied singularly and therefore their combined effects have not been well studied. This study was set out to evaluate the effects of harvesting stage, curing period, and time of topping on postharvest quality of stored red bulb onions. The study was carried out in Yatta Subcounty, Machakos County, Kenya. The experimental design was split-split plot laid out in a 3 × 3 × 2 factorial arrangement. The treatments consisted of harvesting stage (25%, 50%, and 75% top fall), curing period (none, 1 week, and 2 weeks after harvesting), and time of topping (before and after curing). All the treatments were replicated three times. After 3 months of storage, the bulbs were analyzed for proximate and nutritional composition. Bulbs that were harvested at 75% top fall and cured for one or two weeks before topping retained higher moisture content, bulb weight, crude protein, vitamin C, zinc, potassium, calcium, and iron but lower sodium content after three-month storage. These practices are therefore recommended for maintaining the nutritional quality of bulb onions after harvesting.

The drumstick tree is a fast-growing multipurpose tree with a large biomass and high nutritional value. However, it has rarely been exploited as a protein source. This study investigated solid-state fermentation induced by Aspergillus niger, Candida utilis and Bacillus subtilis to obtain high-quality protein feed from drumstick leaf flour. The results showed that fermentation induced significant changes in the nutritional composition of drumstick leaf flour. The concentrations of crude protein, small peptides and amino acids increased significantly after fermentation. The protein profile was also affected by the fermentation process. Macromolecular proteins in drumstick leaf flour were degraded, whereas other high molecular weight proteins were increased. However, the concentrations of crude fat, fiber, total sugar and reducing sugar were decreased, as were the anti-nutritional factors tannins, phytic acid and glucosinolates. After 24 h fermentation, the concentrations of total phenolics and flavonoids were increased. The antioxidant capacity was also significantly enhanced.

Process Strategy

Solid-state fermentation (SSF) of rice bran (RB) employing the edible fungus Pleurotus sapidus was investigated as a process strategy to improve the nutritional quality of this low-cost and abundant substrate. During fermentation, samples were withdrawn at different time intervals (4, 6, and 10 days) and further analyzed. Established methods were deployed to monitor the changes in nutritional composition (carbohydrates, proteins, ash, and lipids). Additionally, changes in fatty acid composition was studied as a function of culture progress. Results showed that the SSF of rice bran increased total carbohydrates from 36.6% to 50.2%, total proteins from 7.4% to 12.8%, and ash from 7.6% to 11.5%. However, the total lipid content was reduced from 48.5% to 27.8%. The fatty acid (FA) composition of RB included mainly oleic, linoleic, and palmitic acids. Upon fermentation with P. sapidus, small differences were found: linoleic acid and oleic acid content were increased by 0.4% and 1.1%, respectively, while palmitic acid content was reduced by 0.8%. This study demonstrated an improvement in the nutritional quality of RB after fermentation with P. sapidus, since protein, carbohydrates, minerals, and specific FA components were increased. As a whole, our results indicate that fermented rice bran could be used as a high-quality animal feed supplement.

Ssf Process

Solid state fermentation (SSF) represents a technological alternative for a great variety of legumes and cereals, or combinations of them, to improve their nutritional quality and to obtain edible products with palatable sensorial characteristics. Chickpeas (Cicer arietinum L.) are prone to develop the hardening phenomenon, also known as hard-to-cook (HTC) defect, when stored under adverse conditions of high temperature (≥ 25 °C) and high relative humidity (≥ 65%). This hard-to-cook phenomenon causes increases in cooking time, decreases in nutritional quality and deterioration of sensorial attributes of chickpea. The objective of this work was to study the effect of SSF on chemical composition and nutritional quality of fresh and hardened chickpeas. The hardening of chickpea ( Cicer arietinum L. Blanco Sinaloa 92 variety) for human consumption, was produced by accelerated storage (33-35 °C, RH = 75%, 180 days). A Rhizopus stolonifer spore suspension (1 x 106 spores/mL) was used as starter for the fermentation. The temperature and time of the SSF process were 35.8 °C and 42.7 h, respectively. The tempeh was obtained from fresh and hardened chickpea. The SSF process caused a significant increase ( p ≤ 0.05) in crude protein, true protein (19.6-19.9 to 23.2-23.4%), protein solubility, in vitro digestibility (68.6-73.1% to 79.9-80.5%), available lysine (2.19-3.04 to 3.19-4.07 g lysine/ 16 N), palmitic acid, and stearic acid, and a significant decrease ( p ≤ 0.05) in lipids, minerals, linoleic acid, phytic acid (8.82-10.73 to 2.11 g phytic acid/g dry matter), and tannins (16.1-22.4 to 3 mg catechin/g dry matter). The SSF process improved significantly the quality of fresh and hardened chickpea.

Abstract Background: The drumstick tree is a fast-growing multipurpose tree with a large biomass and high nutritional value. However, it has rarely been exploited as a protein source. This study investigated solid-state fermentation induced by Aspergillus niger, Candida albicans and Bacillus subtilis to obtain high-quality protein feed from drumstick leaf flour. Results: Solid-state fermentation induced significant changes in the nutritional composition of drumstick leaf flour. The concentrations of crude protein, small peptides and amino acids increased significantly after fermentation. The protein profile was also affected by the fermentation process. Macromolecular proteins in drumstick leaf flour were degraded, whereas other high molecular weight proteins were increased. However, the concentrations of crude fat, fiber, total sugar and reducing sugar were decreased, as were the anti-nutritional factors tannins, phytic acid and glucosinolates. After 24 h fermentation, the concentrations of total phenolics and flavonoids were increased. The antioxidant capacity was also significantly enhanced. Conclusions: The results suggested that the feed quality of drumstick leaves was greatly improved by solid-state fermentation.
