    An approach to manufacturing well-being milk chocolate in partial replacement of lecithin by the functional plant-based combination
    (Wiley, 2024) Patel, Harshvardhan; Bains, Aarti; Sridhar, Kandi; Ali, Nemat; Najda, Agnieszka; Tosif, Mansuri M.; Dhull, Sanju Bala
    Lecithin is constituted of a glycerophospholipid mixture and is abundantly used as an emulsifying agent in various food applications including chocolate production. However, overconsumption of lecithin may create an adverse effect on human health. Thus, this study aims to replace the lecithin with plant-based gums. Different ratios of guar and arabic gum (25%-75%) and their blend (25%-75%) were employed as partial replacement of lecithin. Milk chocolate prepared using 40% guar gum (60GGL [guar gum, lecithin]), 25% arabic gum (75AGL [arabic gum, lecithin]), and a blend of 15 arabic gum and 10 guar gum (65AGGL [arabic gum, guar gum, lecithin]) showed similar rheological behavior as compared to control chocolate (100% lecithin). The fat content of 65AGGL (37.85%) was significantly lower than that of the control sample (43.37%). Rheological behavior exhibited shear-thinning behavior and samples (60GGL-75GGL-80GGL, 65AGL-75AGL, and 65AGGL-75AGGL) showed similar rheological properties as compared to control. The chocolate samples (60GGL and 65AGGL) showed significantly (p < .05) higher hardness values (86.01 and 83.55 N) than the control (79.95 N). As well, gum-added chocolates exhibited higher thermal stability up to 660(degrees)C as compared to the control sample. The Fourier transform infrared spectroscopy (FTIR) analysis revealed predominant beta-(1 -> 4) and beta-(1 -> 6) glycosidic linkages of the gums and lecithin. Sensory evaluation revealed a comparable score of gum-added milk chocolate in comparison to control samples in terms of taste, texture, color, and overall acceptance. Thus, plant exudate gums could be an excellent alternative to lecithin in milk chocolate, which can enhance the textural properties and shelf life.

    Application of mucilage-based functional and clean-label food ingredients as vegan fat replacers in different food products
    (Elsevier Sci Ltd, 2025) Tosif, Mansuri M.; Bains, Aarti; Goksen, Gulden; Kaushik, Ravinder; Chawla, Prince
    The increasing demand for vegan and clean-label food products has prompted the exploration of natural and sustainable ingredients to replace animal-based fats. Mucilage, a hydrocolloid derived from various plant sources, has emerged as a promising alternative due to its unique physicochemical properties, including high water holding capacity, emulsification, and gelation abilities. This paper provides a comprehensive analysis of mucilage-based functional ingredients as vegan fat replacers in diverse food applications. The extraction, characterization, and functionalization of botanical mucilage show that it can mirror the sensory and textural properties of conventional fats. It also examines the impact of mucilage incorporation on the nutritional profile, consumer acceptance, quality, and regulatory considerations, including bakery, dairy, and meat products. Ultimately, mucilage-based fat replacers could provide a viable solution for reducing fat content in high fat containing food products; however, further research is needed to optimize its functionality and explore its bioavailability in the human body.

    Application of Taro (Colocasia esculenta) Mucilage as a Promising Antimicrobial Agent to Extend the Shelf Life of Fresh-Cut Brinjals (Eggplants)
    (Mdpi, 2023) Tosif, Mansuri M.; Bains, Aarti; Goksen, Gulden; Ali, Nemat; Rusu, Alexandru Vasile; Trif, Monica; Chawla, Prince
    Taro rhizomes are a rich source of polysaccharides, including starch and mucilage. However, mucilage has excellent anti-microbial efficacy, and unique gel-forming and techno-functional properties. Therefore, this study aimed to extract and utilize taro mucilage (TM), which is viscous and has a gel-like texture, for the shelf-life enhancement of fresh-cut brinjals (eggplants). Mucilage was extracted using hot-water extraction and the yield was calculated to be 6.25 +/- 0.87% on a dry basis. Different formulations of coating gel solutions were prepared: 1, 2, 3, 4, 5, 6, and 7%. The selection of the coating gel solution was carried out based on particle size. The smallest particle size was observed in treatment T5 (154 +/- 0.81 nm) and zeta potential -27.22 +/- 0.75 mV. Furthermore, cut brinjals were coated with the prepared mucilage gel solution and this showed a significant effect on the overall physicochemical properties of cut brinjals. Maximum weight loss occurred on the 10th day (12.67 +/- 0.24%), as compared with coated brinjals (8.99 +/- 0.42%). Minor changes were observed in pH, for the control sample significantly decreased from 4.58 +/- 0.45 to 2.99 +/- 0.75 on the 0th day to the 10th day, respectively. Titrable acidity of coated and uncoated cut brinjals was found to be at 0.31 +/- 0.44% on the 0th day, which increased up to 0.66 +/- 0.20% for the control and 0.55 +/- 0.68% for coated brinjals on the 10th day. The taro mucilage coating gel (TMCG) solution showed pseudo-plastic behavior or shear-thinning fluid behavior. FTIR data confirmed the existence of several functional groups including various sugars, proteins, and hydroxylic groups. Antioxidant activity of coated and uncoated cut brinjals was found to be 22.33 +/- 0.37% and 22.15 +/- 0.49%, respectively. The TMCG solution showed effective results towards the various food pathogenic microorganisms. Overall, it is a natural, renewable resource that is biodegradable. This makes it an environmentally friendly alternative to synthetic additives or thickeners. It is cost effective, easily available, eco-friendly, and non-toxic. This can be an attractive feature for consumers looking for sustainable and eco-friendly options.

    (Elsevier, 2024) Patel, Harshvardhan; Bains, Aarti; Tosif, Mansuri M.; Ali, Nemat; Goksen, Gulden; Dhull, Sanju Bala; Chawla, Prince
    Lecithin is potentially used in various food applications due to its emulsifying and stabilizing properties. However, overconsumption of lecithin may cause several diseases and side effects in the human body. Therefore, in this study, we used a blend of guar and acacia gums as a partial replacement for lecithin in white chocolate. Different concentrations of the blend (25-75 %) were used to replace lecithin and white chocolate containing 75 % lecithin, 15 % acacia gum and 10 % guar gum blend (75GAGL) exhibited comparable rheological properties as compared to the control sample. Consequently, the selected sample was characterized using different analytical techniques. FTIR results showed a similar peak of various functional groups of sugars, proteins, and uronic acids for 75GAGL and control samples. Physicochemical analysis and shelf-life evaluation were conducted during the 150-day storage period. Lower fat content (41.64 +/- 1.23 %) and highest protein content (5.41 +/- 0.08 %) were observed for the 75AGGL sample as compared to the control on the 0(th) day and a non-significant difference was shown on the 150th day. Overall, physicochemical data revealed minor changes in the nutritional aspects for both control and 75GAGL samples. DSC and TGA data proved that 75GAGL and the control sample have similar heat stability (melting point) and the peak was observed at 36.93 degrees C for 75GAGL and 37.11 degrees C for control. The addition of gum blend in chocolate 75GAGL (9985 g force in 2.24 Sec) displayed similar hardness as compared to the control sample (12,448 g force in 2.68 Sec). Results of texture analysis for 5AGGL and control samples exposed similar hardness values. Furthermore, the color assessment showed a non-significant difference in color values of both chocolates during 150 days of storage. 75AGGL received comparable scores to the control sample during sensory analysis. Overall, it could be proven that plant-derived gums can be effectively used for the partial replacement of lecithin for white chocolate production with desirable textural and sensory properties.

    (Elsevier, 2024) Das Adhikary, Nibedita; Bains, Aarti; Tosif, Mansuri M.; Chawla, Prince; Ali, Nemat; Ansari, Mushtaq Ahmad; Dhull, Sanju Bala
    Non -conventional starch sources have attracted substantial attention due to their preferred physicochemical and mechanical properties similar to conventional sources. This study aimed to enhance the mechanical properties of mango seed kernel starch (MSKS) based films reinforced with carboxymethyl cellulose (CMC) and gum acacia (GA). Physical modification of MSKS was carried out using microwave -assisted at 180 W for 1 min. SEM results confirmed the oval and irregular shape of starch. The particle size of native starch (NS) (754.9 +/- 20.4 nm) was higher compared to modified starch (MS) 336.6 +/- 88.9 nm with a surface charge of -24.80 +/- 3.92 to -34.87 +/- 3.92 mV, respectively. Several functional groups including hydroxyl (O - H) and carboxyl (C - H) were confirmed in NS and MS. Different ratios of the MS, NS, CMC, and GA were used for the fabrication of films. Results revealed the higher tensile strength of M/C/G-1 (57.45 +/- 0.05 nm) and M/C/G-2 (50.77 +/- 0.58), compared to control C-4 (100 % native starch) (4.82 +/- 0.04) respectively. The ternary complex provided excellent permeability against moisture and the film with a higher starch concentration confirmed the uniform thickness (0.09 - 0.10 mm). Furthermore, selected films (M/C/G-1 and M/C/G-2) reduced the microbial growth and weight loss of the bun compared to the control (C-4) film. Thus, the ternary complex maintained the freshness of the bun -bread for 14 days. It can be potentially used as a cost-effective and eco-friendly packaging material for food applications.

    (Wiley, 2023) Tosif, Mansuri M.; Bains, Aarti; Dhull, Sanju Bala; Chawla, Prince; Goksen, Gulden
    In recent years, the demand and market for minimally processed fruits are increasing worldwide. Fresh-cut apples are extremely sensitive to environmental factors including oxygen, temperature, and microorganisms in resulting the browning of apples. Therefore, in this study, different concentration of blended edible-coating solution was prepared using Aloe vera and carboxymethyl cellulose (1:1, 1:2, 2:1, 3:3, 3:2, 4:2, 2:4, 3:4, and 4:3, respectively). Lease particle size (101.74 +/- 0.67 nm) of the coating solution was observed with 3% A. vera and 2% carboxymethyl cellulose (CMC). Afterward, the shelf life of the apples was evaluated for 10 days at refrigeration condition. Results showed that a significant difference was found in weight loss of coated (6.42%-10.26%) and uncoated apples (8.12%-15.32%) for 2-10 days. Moreover, the titrable acidity of the cut apples increased during the storage time. Rheological data emerged that the viscosity of the coating solution decreases with the increasing temperature from 0 to 50 degrees C. Fourier transform infrared spectroscopy data confirmed the presence of hydroxyl group (-OH), C=O, C-O, and N-H banding in the A. vera, CMC, and blend-coating solution. The blend solution indicated excellent antimicrobial efficiency. Total phenolic content of coated and uncoated apples at 0 day was 737.55 mg GAE kg(-1) for uncoated and 717.88 mg GAE kg(-1), respectively. Whereas, aerobic and psychrotrophic bacteria counts for edible coated apples significantly lower than control apples. For coated apples, aerobic and psychrotrophic bacteria counts were 1.59 +/- 0.84 and 1.25 +/- 0.49 log CFU g(-1) were 4.26 +/- 0.67 and 2.68 +/- 0.22 log CFU g(-1) at 10th day, respectively. Overall, it can be inferred that blend of A. vera and carboxymethyl cellulose could be used as a nontoxic potential anti-browning and antimicrobial component for the enhancement of the shelf life and additional nutritional value of fresh-cut apples.

    (Elsevier, 2025) Tosif, Mansuri M.; Bains, Aarti; Goksen, Gulden; Rehman, Mohd Ziaur; Ali, Nemat; Chawla, Prince
    This study aimed to utilize the different plant-derived mucilage sources for the partial replacement of palm oil in compound chocolate. Colocasia esculenta rhizome mucilage (CEM), Cordia dichotoma fruit mucilage (CDM), and Psyllium husk mucilage (PHM) were extracted using suitable green methods. Spray-dryer was used to obtain the uniform mucilage powder and the yield of spray-dried CEM (4.65 f 0.79%), CDM (13.44 f 0.27%), and PHM (48.12 f 0.86%) were calculated on a dry basis. Furthermore, different ratios of the mucilage and palm oil (0-100%) were used for the preparation of chocolate spread. CEM30 (30% CEM and 70% palm oil) showed similar viscosity compared to the control (CEMC). The selected compound chocolate was stored for 120 days and physicochemical data revealed a non-significant (p < 0.05) difference throughout 120 days of storage. CEMC exhibited 516.75 f 0.27 kcal/100 g energy values which was higher than CEM30 (485.24 f 0.77 kcal/100 g) on the 0(th) day. Differential calorimetry (DSC) data confirmed the similar melting behavior around 37 degrees C for both samples. On the 120(th) day, CEM30 displayed a similar texture as CEMC. The L* value of CEMC showed 48.54 f 0.42 and for CEM30 it was 46.89 f 0.58 on the 0th day. Overall, CEM30 has proven the most suitable formulation that can be effectively used as a partial substitute for palm oil as a cost-effective natural ingredient in the chocolate industry.
