This study evaluated the effect of the replacement of chicken skin (CS) at various percentages (0%, 25%, 50% and 100%) of black jelly mushroom and olive oil on the physicochemical and microstructural properties of chicken meat emulsion. Emulsions with 100% CS (Control), 50% CS + 50% OO, 50% CS + 50% BJM, 50% CS + 25% OO + 25% BJM, 100% OO and 100% BJM were developed. The pH value, cooking loss, protein content, carbohydrate content, textural properties and shear force of all fat-replaced samples were comparable to the control. The most positive results were demonstrated in the emulsion with 100% BJM, which had lower fat content (1.31±0.84%) and better emulsion stability (%TEF:7.97±4.16%, %EFAT:12.97±6.53%), water-holding capacity (86.67±3.06%), and moisture content (76.69±2.13%). The colour profiles of the BJM-incorporated samples had higher redness and the OO-incorporated sample had higher lightness and yellowness. The micrographs revealed a harmonious distribution of fat droplets and mushroom particles in all samples' protein matrices. In conclusion, the black jelly mushroom is capable to be used as a fat replacer in producing low-fat meat emulsion, and its incorporation at 100% level has the highest potential.","PeriodicalId":12410,"journal":{"name":"Food Research","volume":"11 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135086960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the level of acceptance of herbal medicines is increasing and replacing modern medicines due to the plant safety, efficiency, low cost and availability throughout the world. Leaves of Ocimum sanctum (Linn) have been proven to possess anti -diabetic effects in experimental animals, but the mechanism of anti-diabetic remains indeterminate. Research has been conducted to investigate the total phenolic content and anti-diabetic activity of Ocimum sanctum (Linn) dried and fresh leaves in three different extracts. A correlation between the total phenolic content and anti-diabetic activity was established. Three types of extracts, cold water, methanol and chloroform of dried and fresh leaves of Ocimum sanctum (Linn), were prepared by evaporating the extraction solvent at 40°C except for cold water extract at 50°C. Stock solutions of 10 mg/mL of each type of extract were prepared using dimethyl sulfoxide (DMSO). The folin-ciocalteu method was used to determine total phenolic content, while 3, 5-dinitro salicylic acid (DNS) method was used to determine α-amylase inhibition activity by different extracts of dried and fresh leaves. Generally, all the extracts of dried leaves of Ocimum sanctum (Linn) contain more total phenolic content and show the highest α-amylase inhibition activity as compared to fresh leaves. The highest total phenolic content and α-amylase inhibition activity were found in the methanol extracts of both dried and fresh leaves. The total phenolic content in methanol extracts of dried and fresh leaves was 0.780 mg and 0.700 mg GAE/g extract, respectively. While the percentage of inhibition of methanol extracts for dried and fresh leaves were 47% and 39.3%, respectively. The IC50 of methanol extracts of dried and fresh leaves were determined using different concentrations of methanol extracts of fresh and dried leaves (3, 6, 9, 12 mg/mL). Increasing the concentration of Ocimum sanctum (Linn) dried and fresh leaves decrease the activity of αamylase. The amount of dried and fresh leaves required to inhibit 50% of α-amylase activity was 10.4 and 11.8 mg/mL, respectively. A positive correlation was found between total phenolic content and α-amylase inhibition activity using Pearson correlation in SPSS 16.0 for dried and fresh leaves with R2 = 0.994 and R2 = 0.991, respectively. In conclusion, the methanol extract of Ocimum sanctum (Linn) dried leaves has a good potential to be used as an anti-diabetic agent.","PeriodicalId":12410,"journal":{"name":"Food Research","volume":"11 14","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135086952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Total phenolic content (TPC) was significantly higher in green C. robusta (5.48 mg/g) compared to green C. arabica (4.67 mg/g). However, there was significantly lower phenolic content in both roasted coffee types. Similarly, CGA content was higher in green C. robusta coffee (2.39 mg/g) compared to roasted C. robusta coffee (0.74 mg/g). Caffeine content was significantly higher in roasted C. robusta (1.36 mg/g) compared to green C. robusta (1.23 mg/g) and green C. arabica (1.04 mg/g). The extract of green C. robusta produced a larger mean diameter of inhibition zones at all concentrations against bacteria tested compared to C. arabica. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of all samples on L. casei were 50 mg/mL, while on S. mutans were 240 mg/mL. The MIC and MBC for green and roasted C. robusta and C. arabica tested on P. gingivalis were 100 mg/ml and 200 mg/mL, respectively. The results showed that green and roasted Robusta coffee had higher chlorogenic acid, total phenolic contents, and good antimicrobial activity compared to its counterparts.

However, constant consumption of processed foods has been linked to chronic diseases. The unhealthy results of instant foods serve as an eye-opener for the population to demand the availability of healthy food. Some people resort to plant-based food for health reasons and mushrooms are a great option since they have been utilized as food and drugs since time immemorial, and are a great substitute or even a replacement for unhealthy foods. Mushrooms have long been regarded as a high-nutritional-value food and a vital agent in the degradation of organic matter, an ideal decomposer of agricultural and forest litter. Additionally, mushrooms are obligatory saprophytic, spore-forming eukaryotic organisms belonging to the fungal group, which can be harnessed mostly in a healthy environment. Their dominance as a medicinal food gained global traction and are now cultivated worldwide. Mushrooms, in addition to vitamins, nucleic acids, and minerals, contain β-D-glucan, a prebiotic that has immunomodulatory and anti-inflammatory properties and can be used as an adjuvant in conventional chemotherapy. Furthermore, mushrooms increase food palatability, and their protein and carbohydrate qualities are ideal counterparts to muscle foods such as meat and fish. These edible macrofungi can be considered a superfood and a nutri-med crop with a wide range of biological potentials due to their significant benefits as a combination of food and medicine and because they are grown in an environmentally friendly manner.","PeriodicalId":12410,"journal":{"name":"Food Research","volume":"11 13","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135086953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of this, whole grain corn was subjected to various drying techniques to evaluate the drying performance and its quality retention. Grain corn was harvested at an optimum maturity of 110 days after planting and dried in ambient, sun and oven at 40°C. Ambient drying of whole grain corn showed the longest drying time, followed by sun drying and oven drying at 40°C. The time taken to reduce moisture content to less than 12% (wet basis) was observed to be 359 hrs for air-dried samples, 292 hrs for sun-dried samples and 55.5 hrs for oven-dried samples. Mathematical modelling for each drying technique demonstrated that Midili’s equation displayed the best fitting to describe the drying characteristics of air-dried samples of grain corn, while the diffusion approach’s equation was the best mathematical model for sun and oven-dried samples.
