Efficacy of Chitosan, Pectin and Xanthan as Cold Gelling Agents in Emulsion Gels Stabilized with Legume Proteins to Be Used as Pork Backfat Replacers in Beef Burgers. Gels 2023; 9:970. [PMID: 38131956 PMCID: PMC10742780 DOI: 10.3390/gels9120970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 12/09/2023] [Accepted: 12/10/2023] [Indexed: 12/23/2023] Open
Abstract
This study aimed to develop stable emulsion gels enriched in polyunsaturated fatty acids, formulated with a mixture of olive (75%) and linseed (25%) oils, by incorporating two different stabilizers-pea and soy protein isolates-and three different cold gelling agents-chitosan, pectin and xanthan-to be used as pork backfat replacers in beef burgers. The color, pH, stability and textural properties of the emulsion gels were analyzed as affected by cold storage (4 °C, 7 days). Proximate composition, fatty acid content, technological and sensory properties were determined after burger processing. Meanwhile, color, pH, textural parameters and lipid oxidation were monitored in burgers at 0, 5 and 10 days of storage at 4 °C. A reduction of the fat content between 21.49% and 39.26% was achieved in the reformulated burgers as compared with the control, while the n-6/n-3 polyunsaturated fatty acid ratio decreased from 5.11 to 0.62. The highest moisture and fat retention were found in reformulated burgers made with xanthan, both with pea and soy proteins; however, their textural properties were negatively affected. The reformulated burgers made with chitosan were rated highest for sensory attributes and overall acceptability, not significantly different from the controls.

Abstract
Rising health concerns and the diet-health link drive demand for healthier foods, prompting meat manufacturers to reformulate traditional products. These manufacturers have reduced fat content to enhance nutritional quality, which is essential for maintaining desired product features. As a result, numerous strategies have emerged over recent decades to decrease fat and enhance the lipid profiles of meat products. Among these strategies, using hydrocolloids, emulsification, encapsulation, or gelation of oils to produce fat substitutes stands out. Using gels allows fat replacers with characteristics similar to animal fat (similar rheological, physical, or appearance properties) but with a much healthier lipid profile (by incorporating highly unsaturated oils). Therefore, this manuscript aims to comprehensively describe the main fat replacers used to prepare meat products. In addition, an in-depth review of the latest studies (2022-2023) that use novel gels to reform meat products has been made, indicating in each case the implications that the reformulation produces at a physicochemical, nutritional, and sensory level. Given the reported results, it seems clear that the strategy of using bigels or emulgels is very promising and allows obtaining nutritionally highly improved meat products without affecting their sensory or physicochemical properties. However, the best conditions to obtain a novel gel suitable for use as a fat substitute for each meat product still need to be studied and correctly defined. Moreover, these advancements can pave the way for more extensive studies on using novel gel techniques in other food industries, expanding their applicability and leading to healthier consumer options across various food categories.

Reformulation of Bologna Sausage by Total Pork Backfat Replacement with an Emulsion Gel Based on Olive, Walnut, and Chia Oils, and Stabilized with Chitosan. Foods 2023; 12:3455. [PMID: 37761164 PMCID: PMC10529321 DOI: 10.3390/foods12183455] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/13/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
Bologna sausage, also called "la grassa", is a very popular meat product despite its high fat content and lipidic profile raising serious negative health concerns. An emulsion gel containing olive, walnut, and chia oils, stabilized with soy protein isolate, transglutaminase, and chitosan, was used as total pork backfat replacer in Bologna sausage. The nutritional, textural, and technological properties were assessed and sensory analyses were conducted. Color, pH, and lipid oxidation were monitored during 18 days of cold storage (4 °C). A normal fat Bologna sausage was used as a control reference. A decrease in the n-6/n-3 ratio from 16.85 to 1.86 (by 9 times) was achieved in the reformulated product as compared with the control, while the PUFA/SFA ratio increased from 0.57 to 1.61. Color measurements indicated that the lightness and yellowness increased while redness slightly decreased in the reformulated product. The total substitution of pork backfat in Bologna sausage by the emulsion gel developed in the present study was realized without significantly affecting the technological properties, the oxidative stability and the overall acceptance by the consumers.

Badar IH, Li Y, Liu H, Chen Q, Liu Q, Kong B. Effect of vegetable oil hydrogel emulsion as a fat substitute on the physicochemical properties, fatty acid profile, and color stability of modified atmospheric packaged buffalo burgers. Meat Sci 2023; 199:109143. [PMID: 36827828 DOI: 10.1016/j.meatsci.2023.109143] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 02/04/2023] [Accepted: 02/16/2023] [Indexed: 02/21/2023]
Abstract
Buffalo burgers were prepared with 50% or 100% buffalo backfat substitution using walnut, and peanut oil emulsion gels (EGs) blended with chia flour. Burgers were stored at 2 °C in modified atmosphere packaging for 12 days. The fat replacement decreased total fat by 26% and increased ash by 34%. Hardness and chewiness decreased with increasing the fat replacement; however, it did not affect springiness and cohesiveness values. Burger reformulations led to an increase in cooking yield (10%). Walnut oil EGs increased PUFA level up to 458%. Both oils enhanced PUFA/SFA and ω-6/ω-3 ratios and atherogenic and thrombogenic indices. Concerning color attribute, about 66% reduction was observed in redness values during the storage period of 12 days. Moreover, the sensory scores for all attributes, i.e., appearance, odor, flavor, and juiciness, were in the acceptable range of five or above in the reformulated burgers. In conclusion, 50% fat substitution using walnut and peanut oil EGs improved the nutritional profile of buffalo burgers without compromising the technological and sensory characteristics.

Effects of Pork Backfat Replacement with Emulsion Gels Formulated with a Mixture of Olive, Chia and Algae Oils on the Quality Attributes of Pork Patties. Foods 2023; 12:foods12030519. [PMID: 36766048 PMCID: PMC9914842 DOI: 10.3390/foods12030519] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 01/13/2023] [Accepted: 01/20/2023] [Indexed: 01/25/2023] Open
Abstract
This paper reports on the development of new emulsion gels containing a mixture of olive, chia and algae oil emulsified with soy protein isolate and stabilized by two different cold gelling agents, gelatin (EGEL) and chitosan (ECHIT), and to evaluate their potential use as pork backfat replacers in cooked pork patties. Reformulated patties were produced by half and full pork backfat replacement and compared to normal fat patties and reduced fat content patties made by replacing half of the added fat with water. Color parameters, pH and thermal stability of the emulsion gels were determined at processing and after 10 days of refrigerated storage. Proximate composition, fatty acid profile, technological properties and sensory attributes were evaluated after patty processing, while color parameters, pH and lipid oxidation were monitored in patties during 15 days of refrigerated storage (4 °C). Reformulated patties showed significant improvements of the lipid profile (lower saturated fatty acid content and n-6/n-3 ratio and higher long-chain polyunsaturated fatty acid content) as compared to the controls. In terms of technological properties, chitosan was more effective than gelatin as a stabilizer of the emulsion gel. All reformulated patties showed a good evolution of lipid oxidation during storage and acceptable sensory attributes.
