Nutritional Profile Analysis of Red Bean Tempeh Fermented Using <i>Rhizopus Oligosporus </i>at Different Time

Investigation of non-soybean legumes as raw material for making tempeh is very important to be carried out continuously considering soybean production tends to decline from year to year. This study aims to analyse the potential of red bean seeds as raw material for tempeh and changes in their nutritional profile when fermented at different fermentation times. The red beans were soaked in water overnight at room temperature and then boiled for 20 minutes. After boiling, the red beans were drained and then fermented for 36, 48, and 60 hours using a suspension of <i>Rhizopus oligosporus</i> with a weight of 2 g for each 1000 g of red beans. Red bean tempeh was analysed for quality using test parameters including physical appearance (color, texture, and aroma) and nutritional profile (calorie value, ash, water, crude fiber, fat, protein, and carbohydrate content). The physical appearance and nutritional profile of red bean tempeh were compared with those of soybean tempeh, while the quality of tempeh was compared with Indonesian national standards for tempeh. The results showed that the length of fermentation time significantly affected the nutritional profile of tempeh. Red bean tempeh fermented for 48 hours had a nutritional profile including energy, water, ash, protein, fat, carbohydrate, and crude fiber content of 201.59 kcal/100 g tempeh, 61.97%, 1.18%, 16.19%, 10.98%, 8.29%, and 1.13%, respectively. The physical appearance and nutritional profile of red bean tempeh have met the tempeh quality requirements issued by the Indonesian national standard for tempeh. Therefore, red bean seed appears to be as good as raw materials for tempeh production.

Determining the Ideal Temperature and Fermentation Duration to Enhance Crude Protein Content and Reduce Crude Fiber in Rice Bran Using Solid-State Fermentation with Aspergillus niger (USM F4)

Solid-state fermentation (SSF) offers a sustainable method for enhancing the nutritional quality of agricultural residues such as red rice bran. This study aimed to determine the optimal temperature and duration for SSF of red rice bran, focusing specifically on increasing the crude protein (CP) content and reducing the crude fiber (CF) content. SFF of rice bran with Aspergillus niger (A. niger) USM F4 was conducted over 14 consecutive days at three different temperatures (25°C, 35°C, and 45°C). A total of 63 samples of rice bran were divided into three temperature groups, each containing 21 samples. Three samples per group were collected at 48-hour intervals over the 14-day fermentation period. The fermentation process for the collected samples at 48-hour intervals was halted by oven drying at 60°C for 24 hours. The fermented products were subjected to proximate analysis for crude protein (CP), ash, ether extract (EE), and crude fiber (CF) contents using the methods outlined by the Association of Official Analytical Chemists (AOAC). The results revealed a significant effect of temperature and fermentation duration on CP, ash, EE, and CF content when compared to the unfermented rice bran kept at room temperature (25oC). The peak values of CP and the highest degradation of CF across all temperature levels were observed on day 10 while the maximum increase in ash and EE content occurred on day 8. Among the temperature conditions, the highest CP values and the lowest CF values were recorded at 35°C. Conversely, the lowest improvements in CP and CF degradation were observed at 25°C on day 10. In conclusion, the optimal conditions for SSF of rice bran with A. niger to enhance CP content and degrade CF are a temperature of 35°C and a fermentation duration of 10 days.

In addition, Yam Peel had the highest moisture content (8.46%), followed by Palm Chaff (5.87%), Oil Palm Empty Bunch (4.62%), and Saw Dust (2.83%). This suggested that Saw Dust was the driest substrate. Furthermore, Oil Palm Empty Bunch had the highest crude lipid content (1.94%), followed by Palm Chaff (1.38%), Yam Peel (1.13%), and Saw Dust (0.04%). Moreover, Oil Palm Empty Bunch had the highest crude protein content (2.56%), followed by Yam Peel (2.1%) and Palm Chaff (2.02%). Saw Dust had the lowest crude protein content (1.74%). Besides, Oil Palm Empty Bunch had the highest crude fiber content (48.27%), followed by Palm Chaff (36.94%), Saw Dust (26.17%), and Yam Peel (14.36%). In addition, Saw Dust had the highest carbohydrate content (67.86%), followed by Yam Peel (69.64%) and Palm Chaff (46.65%). Oil Palm Empty Bunch had the lowest carbohydrate content (37.58%). These findings offered valuable insights into the suitability of each substrate for cultivating Pleurotus ostreatus Additionally, it enabled growers to make informed decisions about substrate selection based on the specific nutritional needs and growth requirements of the mushrooms. The impact of various organic waste substrates on the growth dynamics of Pleurotus ostreatus (oyster mushroom), revealed significant variations in several key parameters. In primordial Formation, the number of early-stage fruiting bodies formed varied between 12 and 36 across different substrate formulations. The highest primordial formation was observed in treatment A + B + C + D (36), while treatments involving individual substrates or their combinations had the lowest primordial formation (12). Furthermore, in Fruiting Body Production, the number of mature mushrooms produced varied across treatments. Treatment A + C resulted in the highest number of fruiting bodies (26), while treatments involving combinations of substrates (B + C + D, A + B + C, A + B + C + D, C + D) had the lowest number of fruiting bodies (3). Overall, the findings highlight the influence of specific substrate combinations on various aspects of mushroom growth dynamics. However, the choice of growth substrates did not significantly impact the overall weight and biological efficiency of Pleurotus ostreatus in this study. These results provide valuable insights for optimizing mushroom cultivation practices.

Hybrid meat products: the physicochemical and microstructural properties of beef meat emulsion produced with jackfruit (Artocarpus heterophyllus) flesh and bamboo (Bambusa polymorpha) shoot as meat substitutes

SummaryHybrid meat products are a beneficial approach to incorporating plant proteins into conventional meat formulations, taking into account current market trends that emphasise the partial decrease in animal protein content. This study aimed to evaluate the effects of using different percentages of beef meat (BM), jackfruit flesh (JF) and bamboo shoot (BS) as a meat substitute in beef meat emulsion. Emulsion with 100% BM (Control), (A) 50% JF + 50% BM, (B) 50% BS + 50% BM, (C) 50% BM + 25% JF + 25% BS, (D) 100% JF and (E) 100% BS were developed. Six formulations of meat emulsion samples were prepared and analysed in terms of physicochemical and microstructure properties. The substitution of JF and BS in meat emulsion resulted in more stable emulsion stability. The WHC and pH values showed no significant differences (P > 0.05) between samples. The samples with different percentages of JF and BS had significantly increased (P < 0.05) the moisture content and the crude fibre content, however, it significantly reduced (P < 0.05) the crude protein content. No significant difference (P > 0.05) in ash and fat content for the formulated meat emulsions from the control. One hundred per cent BS showed higher lightness (L*), yellowness (b*) and lower redness (a*) values significantly (P < 0.05) compared to the control. One hundred per cent JF and 100% BS depicted significant differences (P < 0.05) for the textural properties and gel strength compared to the control. The scanning electron microscopy (SEM) provided evidence for the microstructure that the higher the percentages of plant‐based ingredients, the smaller the cavities. Overall, the incorporation of 50% BM + 25% JF + 25% BS could produce the best‐suited meat substitution product.

Production and Optimization of Wine from Mixed (Banana and Watermelon) Fruits Using Sacchromys Crevice

Winemaking is one of the most ancient technologies and is now one of the most commercially prosperous biotechnological processes. Fruits are one of the most important foods of mankind. They are important for the maintenance of health and improving the quality of our diet. Fruit juices are fermented to produce wine, an alcoholic beverage containing 8 to 11 percent alcohol and 2 to 3 percent sugar with energy values ranging between 70 and 90 kcal per 100ml. Due to the release of amino acids and other nutrients from yeast during fermentation, fruit wines are nutritive and tastier. For this reason, the conversion of fruits to value-added products like wine is very essential. This work aimed to produce and optimize mixed fruit (Banana and Watermelon) wine using saccharomyces cerevisiae. The proximate composition of banana with74 ± 00 of moisture content, 0.33 ± 00 of ash content, 0.23 ± 0.01 crude fat content, 1.65 ± 0.05 crude fiber content, 1.2 ± 0.1 protein content and 22.59% carbohydrate content and 91.5±1.5 moisture content, 0.49 ± 0.017ash content, 0.25 ± 0.01crude fat content, 0.6 ± 0.05 crude fiber content, 0.46 ± 0.02 crude protein content and 6.75% of carbohydrate content watermelon fruit were used for wine production. Primary and secondary fermentation of the fruits lasted for 9 and 21 days respectively, pH, titrable acidity, specific gravity and, total soluble solids (brix) were determined before and after fermentation using standard procedures. The specific gravity of the wine was observed to reduce drastically as the fermentation progressed. The pH of the fruit must decrease from 3 to 2.89 and 4 to 3.2 in different percentage of mixture and titrable acidity also increased 0.67- 0.92 in 75B:25Wm, 0.64 -0.9 in 50B:50Wm, and 0.63-0.89 in 25B:75Wm after fermentation. The highest percentages of alcohol content (9.5) was observed in 75B to 25Wm mixed fruit wine in pH 4 and inoculum size 5, and sensory evaluation revealed that the attributes of the wine were acceptable to the majority of the respondents. This study showed that acceptable wine can be produced from mixed fruits banana and watermelon using yeasts Saccharomyces cerevisiae.

Coating of oxidized banana starch and olive oil for the preservation of cherry tomatoes (Solanum lycopersicum cv. Cerasiforme)

Postharvest conservation of fresh fruits and vegetables is a constant challenge in the food industry. Biodegradable coatings represent an innovative and sustainable solution to extend their shelf life. In this context, this research evaluated the influence of a coating based on oxidized banana starch (Musa paradisiaca L. group AAA, cv. Cavendish) and olive oil on the conservation of cherry tomatoes (Solanum lycopersicum cv. Cerasiforme) during their storage at ambient conditions. Coating-forming emulsions were prepared using starch (4% m v-1) with a high degree of oxidation, glycerol, Tween 80, and olive oil. The products were dip coated. The starch extraction yield was 27.26% by the wet milling method. The contents of lipids, crude fiber, proteins, carbohydrates, and ashes tended to decrease in oxidized starches with increasing reaction time, the opposite behavior for humidity (P≤0.05). Solubility and oil absorption capacity increased in oxidized starches, while water absorption and swelling power decreased (P≤0.05). The best combination for the formulation of oxidized starch coatings was 3% (m v-1) of glycerol and 0.3% (m v-1) of oil. This coating reduced weight losses and delayed the ripening process. The results suggested that the use of coatings based on oxidized banana starch and olive oil is an effective strategy for maintaining the quality and freshness of the fruits during a longer storage period.

Six different strains of Eri silkworm are present, named according to their body pattern and color - greenish blue zebra (GBZ), greenish blue spotted (GBS), greenish blue plain (GBP), yellow zebra (YZ), yellow spotted (YS) and yellow plain (YP). Apart from being reared mostly for Eri silk, this lepidopteran insect is also considered as a popular delicacy among the tribes of Northeast India, along with it being moderately famous among the locals too. The proximate analysis of the lyophilized samples was carried out as per AOAC (2015) guidelines and mineral analysis was carried out in atomic absorption spectroscopy. Among the six different strains, YS contained highest moisture (7.82 gm) and crude fiber content (18.8 gm), whereas, YZ showed highest amount of total ash (4.32 gm) and crude fat content (22 gm). Furthermore, carbohydrate content was seen to be highest in GBS (14.41 gm). Hence, this study is aimed to unveil the nutritional worth of the six distinct pupa strains of Eri silkworm in an effort to dispel entomophobia, and promote entomophagy owing to the nutritional benefit it offers.

EFFECTS OF PROCESSING ON THE PROXIMATE AND MINERAL COMPOSITION OF CULTURED AND CAPTURED CLARIAS GARIEPPINUS

Fish and fish products serve as vital protein sources in Africa and the world in general. Since fish is typically processed before consumption, this study investigated how different processing methods affect the proximate and mineral composition of both cultured and captured Clarias gariepinus. The processing techniques employed in this research included smoking, boiling, and oven drying. Cultured catfish were sourced from Oris Farm in Osogbo, Osun State, Nigeria, while captured catfish were obtained from Asejire Dam in Oyo State. The proximate and mineral compositions of fresh, boiled, smoked, and oven-dried samples of both cultured and captured Clarias gariepinus were analyzed in triplicate. The results indicated significant differences (P<0.05) in crude protein, dry matter, moisture, ash, fiber, potassium, and phosphorus content among the different processing methods for both cultured and captured catfish samples. Potassium and phosphorus levels also varied significantly (P<0.05) across the processing methods. Boiled and oven-dried samples of both cultured and captured catfish exhibited higher crude protein and lipid content, suggesting that these processing methods provide consumers with a rich source of protein and essential nutrients. The study concludes that boiling and oven drying with samples possessing highest percentages of protein are the most effective processing methods for preparing Clarias gariepinus, ensuring optimal nutrient retention for consumers.
