Effect of Green Tea Powder on Physicochemical Properties and Glycemic Potential of Sponge Cake

Green tea powder (GTP) is rich in polyphenolic compounds, most particularly catechins. The effects of partial replacement of flour with GTP (10, 20, and 30%) on physicochemical properties, glycemic potential, and sensory attributes were investigated. Results showed a significant reduction in the moisture content, volume, and porosity of sample cakes with the increase in the GTP levels (P≤0.05). The utilization of GTP led to a harder texture and also darker color of sponge cake. The study showed that sponge cakes with good sensory attributes can be produced by the replacement of flour with 10% of GTP. Moreover, the glycemic potential and free radical scavenging activity of sample cakes improved as the GTP replacement increased (P≤0.05). GTP at 10% replacement level is recommended as it is very effective in improving the antioxidant properties, sensory attributes, and also glycemic potential.

Research on microwave‐assisted extraction with blanching pretreatment effect on bioactive compounds of green tea leaves ( Camellia sinensis ) powder

Fresh green tea leaves have been considered by-products. They contain beneficial ingredients of polyphenols, approximately 30%. This study was aimed to investigate the blanching process combined with microwave-assisted extraction of green tea leaves. The best quality extract was obtained by blanching at 85°C for 45 s, then microwave-assisted extracting for 3 min with power of 16 W/g and frequency of 2450 MHz. The extract was added with whey protein isolate of 15%–15.3% and then spray-dried to form green tea powder. The highest antioxidant capacity was observed at 360.20 mg Trolox equivalent antioxidant capacity/g of tea powder. The bioactive compounds were determined as total polyphenol content of 336.65 mg GAE/g, epigallocatechin-gallate of 104.14 mg/g, epigallo-catechin of 62.15 mg/g, epicatechin-gallate of 22.09 mg/g, epicatechin of 19.27 mg/g, and caffeine of 3.13 mg/g. The tea powder was rich in chlorophyll content of 3.52 mg/g with nice green color and nutrition by abundant amino acids. Practical applications In Vietnam, fresh tea leaves, which are not in tea buds, have been often considered as by-products or even wastes. Our project investigated the extraction procedure for creating high-quality extract then used this extract for forming green tea powder by spray drying technology. The product obtained high content of total polyphenol, chlorophyll, and rich content of amino acids, which has better economic efficiency to use for the food or beverage industry in Vietnam.

Innovative Application of Chicken Eggshell Calcium to Improve the Functional Value of Gingerbread.

Food waste, such as eggshell, can be an environmental problem if it is not properly managed. One of the ways to solve this is by using the eggshell as the cheap calcium source in food products. Polish gingerbread fortified with chicken eggshell powder (ESP) calcium was developed to solve the eggshell waste problem and to reduce the risk of osteoporosis. This study focused on the effect of ESP addition on basic composition, sensory evaluation, and antioxidative activity of gingerbread. Two samples of gingerbread without and with 3% (w/w of wheat flour) ESP, with controlled green tea powder (4% w/w of white chocolate) were analyzed. Results of the research showed that the addition of 3% ESP significantly increased the ash and calcium content (p < 0.05) without changing the appearance, aroma, texture, taste profiles, and the hedonic score of gingerbread. The gingerbread samples were then stored for 2 months and were analyzed every month. The hedonic evaluation of the aroma of both gingerbread samples decreased significantly (p < 0.05) during storage. During 2 months of storage, the antioxidative activity of gingerbread fortified with 3% ESP was not significantly different compared to the control (p > 0.05), particularly in ABTS and ORACFL assay. The ABTS, DPPH, and ORACFL assays showed decreasing antioxidative activity during storage, which was also in accordance with decreasing total phenolic content of both gingerbread samples. In PCL assay, the lipid-soluble antioxidant activity in gingerbread with 3% ESP was significantly higher during 2 months of storage, compared to the control (p < 0.05). The developed product might be a potential alternative to improve the calcium (26% daily value (DV) recommendation per 100 g) and antioxidant intake in order to prevent calcium deficiency. Gingerbread enriched with an organic source of calcium may become an innovative product to reduce the risk of developing osteoporosis in the elderly population, having potential health and economic significance, given the incidence of osteoporosis and the costs of treating this disease.

Effects of Tea Powder on the Cooking Properties, Antioxidative Potential and Volatile Profiles of Dried Noodles.

Numerous studies indicate that tea has versatile health benefits, and attempts are being made to use it as a food additive. In this study, three types of tea powder (TP) [matcha tea powder (MTP), green tea powder (GTP), and black tea powder (BTP)] were used in noodle processing, and the cooking properties, antioxidant potential, and volatile profiles of dried tea noodles (DTN) were investigated. Between 0.5% and 2% TP addition decreased the cooking time, cooking loss, and water absorption of DTN, regardless of concentrations. TP decreased the brightness (L*) of the DTN while increasing the greenness (|−a*|) and yellowness (b*) values of matcha tea noodles (MTN) and green tea noodles (GTN), as well as the redness (a*) and yellowness (b*) values of black tea noodles (BTN). The results of the 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) scavenging activity (10.84–95%), 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free scavenging activity (2.03–92.23%), and total phenolic content (TPC) (97.32–540.97 mg/g) of the noodles increased as the TP addition increased. Besides, TP also enriched the flavor of the DTN, with alcohol, aldehydes, and ethers being the main components. In conclusion, the addition of TP positively improved the quality of the DTN and increased its antioxidative potential.

Rheological, textural, and functional characteristics of 3D-printed cheesecake containing guava leaf, green tea, and barley sprout powders

The use of 3D food printing as an alternative to manufacturing customized food is gaining popularity. In this study, functional powders of guava leaf (GL), green tea (GT), and barley sprouts (BS) were tested as edible ink ingredients for printing cheesecake, and their physicochemical and functional properties were evaluated. Particle size and water and oil holding capacities were highest in GL powder, whereas the water-soluble index was highest in BS. In functional powder-added cheesecake, pseudoplastic and shear-thinning behavior was observed which is ideal for 3D printing. The shear modulus (1.87 kPa) of the control cheesecake (without functional powder) was significantly increased to 5 kPa or higher by adding functional powder. The in vitro glycemic index was lowest in GL cheesecake, whereas antioxidant activity and polyphenol content were highest in GT cheesecake. GL and GT powders would be beneficial as an edible ink to improve functional properties, such as antioxidant activity for GT and blood-glucose-lowering effect for BS, with enhanced printability and textural stability of 3D printed cheesecake.

Green tea powder inclusion promoted hatchability through increased yolk antioxidant activity

Dietary supplementation of green tea powder (GTP) changes egg quality of hens, however, whether these changes affect incubation is still unknown. This study was to compare the proteomic difference of incubated eggs from hens with GTP supplemented or not. Huainan partridge chickens (1,080) at 35 wk of age were allocated into 2 groups, one group fed basal diet (CG) and one group fed basal diet plus 1% GTP (EG). After 4 wk feeding, artificially fertilized eggs were collected for yolk cholesterol determination and incubation. During incubation, 6 embryos from each group were randomly selected in each day for yolk protein extraction and quantification. Yolk cholesterol content was significantly lower, while the hatchability was significantly higher in EG than that of the CG group (P < 0.05). Yolk protein concentration at embryonic days (ED) of 0, 2, 6, and 13 showed significant changes and were selected for proteomic analysis by 2-dimensional gel electrophoresis combined with liquid chromatography-tandem mass spectrometry. Fifty-one differentially expressed (DE) protein spots were identified among different incubation stages between CG and EG group which were mainly classified into vitellogenin, immunoglobulin, and ovoinhibitor, and occupied 45.1, 23.5, and 15.7%, respectively, to the total DE proteins. Ovotransferrin, participated in extracellular sequestering of iron ion process, was significantly lower in EG group than that of the CG group (P < 0.05). Ig light chain precursor (Immunoglobulin) exhibited higher expression at ED6 in EG group as compared with that of the CG group, and was participated in immune response related processes. Ovoinhibitor, mainly involved in protease binding activity, showed lower abundance at ED13 in EG group as compared with that of the CG group. Vitellogenin-3, showed lower expression in EG group as compared with that of the CG group, was mainly participated in lipid transportation and localization according to GO enrichment. Chickens fed diet with GTP provided eggs more antioxidant ability that increased hatchability, indicated that GTP could be considered as additive in breeding layer.

REPRODUCTIVE, SERUM BIOCHEMICAL AND HORMONAL TRAITS OF LOCAL QUAIL IN RESPONSE TO DIETARY SUPPLEMENTATION OF GREEN TEA POWDER

This study was conducted on 90 local quail females in six different treatments in order to know the effect of adding green tea powder to the quail diet on the productive, reproductive, biochemical and hormonal characteristics of quail females. The results showed a significant superiority of the birds of the group fed on 1% of green tea powder in hot and cold carcass weight, average egg weight, albumin weight, yolk height and color, and the lowest feed consumption, while the control-treated birds in the number of eggs produced, HDP, ALT, Alkaline and Bilirubin exceeded the other treatments birds. Concerning the lipid profile, blood urea ratio, and AST, the highest significant figures were recorded in the treatment of birds fed a ration to which 3% lipids were added. In contrast, the lowest values ​​for total cholesterol, Tri, VLDL, and blood nitrogen were recorded for birds of the treatment fed at 2% of green tea powder. The results showed that there were significant differences between the six treatment birds in the level of blood hormones, as the highest level of (estrogen), (Ghrelin, leptin, FSH), (T4) and (Growth and LH) were recorded for the control birds, 3% lipid and 1% dried green tea and 2% green tea with 3% lipid, respectively. We conclude from the above that birds fed a supplemented diet of 1% green tea powder were superior in most productive and reproductive traits, especially carcass weight, dressed %, egg weight and internal egg characteristics, compared to other treated birds.

Effects of β-Carotin and Green Tea Powder Diets on Alleviating the Symptoms of Gouty Arthritis and Improving Gut Microbiota in C57BL/6 Mice.

As a chronic metabolic disease caused by disorders of purine metabolism, gout has shown increasing incidence rate worldwide. Considering that gout is not easily treated and cured, further studies are explored to prevent gout development through diet modification. Both β-carotin and green tea powder are rich in dietary fiber, which helps maintain the balance of gut microbiota in humans. The aim of this study was to investigate the effects of β-carotin and green tea powder diet on the prevention of gouty arthritis in relation to the bacterial structure of gut microbiota in mice. We successfully induced gouty arthritis in C57BL/6 mice by injecting monosodium urate (MSU) crystals and feeding high-fat diet (HFD), and further investigated the effects of additional β-carotin and green tea powder in the diets of mice on the prevention of gouty arthritis in mice. Our results showed that diet of β-carotin and green tea powder reduced the joint swelling and pain in mice with gout, reduced the levels of serum uric acid (UA) and three types of pro-inflammatory cytokines, i.e., interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), improved the gut microbiota profile, and reduced the metabolic levels of purines and pyrimidines. In conclusion, our study provided evidence to support the application of β-carotin and green tea powder diet as a dietary adjustment method to prevent and treat gouty arthritis.

Total polyphenols and antioxidant activities of green tea powder from GMB 7 and GMB 9 tea clones

People’s interest in green tea powder is increasing currently. The addition of green tea powder to food products could increase antioxidant activity and other health benefits. GMB 7 and GMB 9 are local tea clones of the Assam variety widely planted in Indonesia’s tea plantation. This study aimed to determine green tea powder’s total polyphenols and antioxidant activity from local tea clones (GMB 7 and GMB 9). Total polyphenol and antioxidant activity were determined by Folin-Ciocalteau and free radical of DPPH methods, respectively. Our results showed that the total polyphenols of green tea powder were 27.61% and 27.31% for the GMB 7 and GMB 9 clones, respectively. Furthermore, the antioxidant activity of green tea powder with IC50 was 15.41 mg/L and 17.32 mg/L for clones GMB 7 and GMB 9, respectively. The results indicate the potential for the development and utilization of local clones to fulfill domestic green tea powder production. Further research is needed to determine the health benefits of green tea powder from clones of The Assam varieties.

ADDITION OF MILK ENHANCED THE TOTAL PHENOLIC CONTENT AND ANTIOXIDANT ACTIVITY OF Camellia sinensis (GREEN TEA) BEVERAGES

The study was aimed to determine the effects of adding milk, sugar and sweeteners to the total phenolic content and antioxidant activity of Camellia Sinensis (green tea) powder. Six green tea samples were brewed in cold water and whisked: Green tea powder (G), green tea powder with sugar (GS), green tea powder with aspartame (GA), green tea powder with milk (GM), green tea powder with milk and sugar (GMS) and green tea powder with milk and aspartame (GMA). The total phenolic content of green tea powder samples was evaluated by using Folin-Ciocalteu assay while α,α-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays were used to measure the antioxidant activity. Results showed that milk addition significantly enhanced by 59.84% of total phenolic content and also increased 26.3% (DPPH) and 42.35% (FRAP) of antioxidant activity of green tea powder, as compared to green tea samples without milk (p&lt;0.05). Strong and positive correlations were found between the total phenolic content and antioxidant activity of green tea powder by using DPPH (r=0.990) and FRAP assays (r=0.997). In conclusion, it might be beneficial when milk is added to green tea as it could help to increase its antioxidant properties.

Optimization of spray-drying process to manufacture green tea powder and its characters.

Tea leaves (Camellia sinensis) have many health benefits due to their abundance of polyphenols with antioxidant activity, most notably epigallocatechin‐3‐gallate (EGCG). To protect those bioactive compounds, the spray‐drying technique of green tea‐extracted solution is conducted because of encapsulating. This study aimed to optimize the spray‐drying condition using the response surface methodology (RSM) with respect to the maximal polyphenol content of the product. Furthermore, the characterizations of resulting powder were determined. The results showed that optimal spray‐drying temperature, input flow rate, and whey protein isolate (WPI) content were evaluated at 136℃, 6.8 rpm, and 10.3% of dry basis, respectively. The obtained green tea powder products, which got from optimal spray‐drying process, achieved total polyphenol content (TPC), EGCG, and caffeine content of 322.06 mg GAE/g, 11.4%, and 2.8% of dry basis, respectively. This result revealed the feasibility of green tea leaves to produce tea powder rich in EGCG and polyphenols by spray‐drying technique, potentially contributing to the diversification of tea products.

Chemical, physical and hedonic characteristics of green tea powder fortified oatmeal cookies

Fortification of oatmeal cookies with ingredients that are physically more attractive and functional is an interesting breakthrough for improving oatmeal cookies to be a favourite healthy food. Green tea was considered to be a food fortification because of its phytochemical content, which is beneficial to health. This study was aimed at getting more insight into the effect of green tea powder (GTP) fortification on physical (texture and colour), chemical (moisture, fat, ash, protein, carbohydrates, crude fibre content, and calories) and hedonic characteristics of oatmeal cookies. The treatments in this study were 5 levels of GTP fortification (each repeated 4 times) i.e., 0, 2, 4, 6, and 8% into the cookie’s dough. There was a significant effect (p≤0.05) of GTP fortification on the texture, colour, ash, fat, crude fibre, and total calorie products. The 2% GTP fortification in oatmeal cookies was the most preferred by the panellists, because the higher percentages of GTP affected the more bitter taste and harder texture. Fortification of oatmeal cookies with 6% GTP produces the final product, namely green tea oatmeal cookies (GTOC), which are low in fat and carbohydrates but high in fibre and protein content. GTP fortification can improve the oatmeal cookie's functional properties

Impact of cold atmospheric plasma on microbial safety, total phenolic and flavonoid contents, antioxidant activity, volatile compounds, surface morphology, and sensory quality of green tea powder

The effects of cold atmospheric plasma (CAP) at different voltages of 20, 22, and 25 kV for 2, 4, 6, and 8 min were investigated on microbial safety, total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity (AA), volatile compounds profile, microstructure and sensory properties of green tea powder. CAP treatments effectively reduced the total microbial, mold and yeast, total coliform, Escherichia coli, and Entrococcus faecalis counts of green tea. E. coli and E. faecalis were completely deactivated in the sample exposed to plasma treatment at 25 kV for 8 min. E. coli showed higher minimum inhibitory and minimum bactericidal concentrations compared to Staphylococcus aureus. TPC, TFC and AA of green tea decreased with increases in CAP voltage and exposure time. GC–mass spectrometry identified 48 different volatile components in green tea. CAP treatment profoundly influenced the amounts of volatile compounds but the trends of changes did not follow the same pattern as the time and/or voltage of the process increased. SEM analysis showed that CAP at 20 kV for 2 or 4 min did not change the surface morphology of green tea powder while higher exposure times and voltages caused substantial ruptures in microstructure of the samples. Sensory acceptability of green tea decreased noticeably after plasma treatment at 25 kV for longer than 4 min. In conclusion, CAP treatment at 22 kV for 4 or 6 min considerably diminished microbial load of green tea powder while relatively satisfactorily preserved its TPC, TFC, AA, volatile components and sensory desirability.

Driving Factor of Consumer Preferences for Food and Beverages Product Enriched with Green Tea Powder

Driving Factor of Consumer Preferences for Food and Beverages Product Enriched with Green Tea Powder

Differential Effects of Green Tea Powders on the Protection of Brown Tsaiya and Kaiya Ducklings against Trichothecene T-2 Toxin Toxicity.

Simple SummaryThe objective of this study is to examine the effects of T-2 toxin (T-2) and green tea powders (GTP) on growth performance, hematology, and pathology parameters in Brown Tsaiya ducklings (BTDs) and Kaiya ducklings (KDs). T-2 toxin shows a strong and differential toxicity in growth suppression, as well as abnormalities in the hematological and pathological parameters of BTDs and KDs. We found that GTP could potentially prevent T-2-induced poor growth performance and improve some hematological parameters. Moreover, BTDs were more sensitive than KDs in terms of responses to T-2 toxicity and GTP detoxification.A 3-week feeding trial in a 3 × 2 × 2 factorial design was conducted with three concentrations (0, 0.5, and 5 mg/kg) of T-2 toxin (T-2) and two levels (0% and 0.5%) of green tea powder (GTP) supplements used in the diets of female brown Tsaiya ducklings (BTDs) and Kaiya ducklings (KDs), respectively. Breed had a significant effect on the growth performances and the relative weights of organs and carcass. In general, the growth performances of KDs were better than BTDs. The relative weights of organs and carcass of BTDs were typically heavier than those of KDs; however, the breast of KDs was heavier than those of BTDs. Both ducklings received 5 mg/kg of T-2 blended in the diet showed lower feed intake and body weight gain (BWG) in the second and the third week. The diet containing 5 mg/kg of T-2 and 0.5% GTP improved the BWG compared to those fed the diet supplemented with 5 mg/kg of T-2 without GTP in BTDs. Ducklings fed the diet containing 5 mg/kg of T-2 induced hypocalcemia and hypomagnesemia, as well as decreased concentrations of creatine phosphokinase and alkaline phosphatase. The concentrations of blood urea nitrogen (BUN) and glutamate oxaloacetate transaminase (GOT) were increased in KDs and BTDs fed the diet containing 5 mg/kg of T-2 without GTP, respectively. However, duckling diets containing 5 mg/kg of T-2 with 0.5% GTP lowered concentrations of BUN and GOT in the blood plasma of KDs and BTDs, respectively. The diet containing 5 mg/kg of T-2 increased the relative kidney weight but decreased the relative breast weight of ducklings. Enlarged gizzards and reduced relative leg weights were observed in BTDs fed the diets containing 5 mg/kg of T-2. In summary, BTDs are more sensitive than KDs in responding to T-2 toxicity and GTP detoxification. Green tea powder has detoxification ability and could potentially mitigate T-2 toxicity on BWG, BUN, and GOT in ducklings.

Matcha Green Tea Powder does not Prevent Diet-Induced Arteriosclerosis in New Zealand White Rabbits Due to Impaired Reverse Cholesterol Transport.

Green tea is associated with decreased risk for cardiovascular disease and stroke. Matcha is a special kind of powdered green tea known for its use in the Japanese tea ceremony. Due to its influence on lipoprotein parameters, it has been postulated to exert antiatherogenic effects. This study investigates whether it modulates the high-density lipoprotein (HDL) function and thereby influences the atherogenic process in an animal model with a strong influence on humans' situation. After a pretreatment phase based on a standard diet, 10 female New Zealand White (NZW) rabbits are fed a high-fat diet for 20 weeks. The treatment group is additionally administered 1% matcha during the whole experiment. Long-term matcha treatment leads to lowered HDL cholesterol, impaired cholesterol transport manifested by reduced in vitro cholesterol efflux capacity, reduced cholesteryl ester transfer protein (CETP)-mediated cholesterol ester (CE) transfer between HDL and triglyceride-rich particles, and reduced macrophage-specific in vivo transfer, where ian increased absorption of cholesterol in the liver but a decreased secretion into bile is observed. Pulse wave velocity, assessed by nuclear magnetic resonance, is increased in matcha-treated animals, and a similar trend is observed for atherosclerotic lesion formation. Long-term matcha green tea treatment of hypercholesterolemic rabbits cause impaired reverse cholesterol transport and increased vascular stiffness, and susceptibility for atherosclerotic lesion development.

Untargeted and targeted metabolomics reveal changes in the chemical constituents of instant dark tea during liquid-state fermentation by Eurotium cristatum

Instant green tea powder was used as raw material to prepare an instant dark tea via liquid-state fermentation by Eurotium cristatum. To understand how the chemical constituents present in fermented green tea develop during fermentation, samples were collected on different days during fermentation for qualitative analyses by ultra-performance liquid chromatography-Q Exactive Orbitrap/Mass spectrometry. Untargeted metabolomics analyses revealed that the levels of original secondary metabolites in the instant green tea changed significantly from day 3 to day 5 during fermentation. Targeted metabolomics indicated that the levels of galloylated catechins (GCs) and free amino acids (FAAs) significantly decreased, but the nongalloylated catechins (NGCs), alkaloids, thearubigins and theabrownins increased dramatically after fermentation. The changes in the contents of catechins, gallic acid and free amino acids in the instant dark tea samples were positively related to the DPPH radical scavenging activities in vitro, and the phenolic acids and FAAs were positively related to the inhibitory effects towards α-glucosidase. These results showed that fermentation by Eurotium cristatum is critical to the formation of certain qualities of instant dark tea.

Effects of Green Tea Powder, Pomegranate Peel Powder, Epicatechin and Punicalagin Additives on Antimicrobial, Antioxidant Potential and Quality Properties of Raw Meatballs

Alternative technologies, which have been developed in order to meet the consumers’ demand for nourishing and healthy meat and meat products, are followed by the food industry. In the present study, it was determined, using the HPLC method, that green tea contains a high level of epicatechin (EP) under optimal conditions and that pomegranate peel contains a high level of punicalagin (PN). Green tea, pomegranate peel, EP and PN were added to meatballs at different concentrations in eight groups. The antioxidant capacities of extracts were measured. The antimicrobial activity was examined for 72 h using three different food pathogens. The highest level of antimicrobial activity was achieved in the 1% punicalagin group, whereas the minimum inhibition concentration (L. monocytogenes, S. typhimurium) was found to be 1.87 mg/mL. A statistically significant decrease was found in FFA, POV and TBARS levels of meatballs on different days of storage (p < 0.05). When compared to the control group, the bioactive compounds preserved the microbiological and chemical properties of meatballs during storage at +4 °C (14 days). It was concluded that the extracts with high EP and PN concentrations can be used as bio-preservative agents for meat and meat products.

Evaluation of the quality characteristics of protein cubes supplemented with moringa leaf (Moringa oleifera Lam.) and green tea powders

The biological activities of moringa leaf and green tea powders were compared, and the quality characteristics of protein cubes supplemented with these powders (5% and 7.5%, respectively) were evaluated. The green tea powder had higher chlorophyll, essential fatty acid, total polyphenol (TPC), and flavonoid (TFC) contents than the moringa leaf powder. The green tea powder had higher levels of 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity (DPPH RSC), Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP) than the moringa leaf powder, indicating higher antioxidant activity. The green tea powder inhibited the nitric oxide production to a greater extent than the moringa leaf powder. The protein cubes that were supplemented with either the moringa leaf or green tea powders had smaller volumes and were harder, chewier, and more easily fractured than the control protein cubes. The protein cubes supplemented with green tea powder had higher TPC and TFC, exhibited higher antioxidant activity (p&lt;0.05), and had better sensory properties in terms of aroma, taste, and texture than the protein cubes supplemented with moringa leaf powder; however, the differences were not significant(p&gt;0.05). The results of the present study indicate that green tea is a more suitable health-oriented functional additive than moringa leaf in the development of high-protein and nutrient-rich bakery products with high consumer acceptability as well as antioxidant and anti-inflammatory properties.
