Tomato processing byproduct valorization in bread and muffin: improvement in physicochemical properties and shelf life stability.

ABSTRACT: Tomato processing industry generates huge waste like tomato skin, seed, and pulp which creates environmental issues. Since tomato pomace contains bioactive compounds and pigments, present study was conducted to investigate the effect of tomato pomace addition on physicochemical characteristics and shelf-life stability of the developed bread and muffin. Refined flour was partially substituted with 35 and 40% tomato pomace in bread and muffin, respectively. Tomato pomace addition in bread and muffin was observed to significantly (p < 0.05) increase the dietary fiber, vitamin C, antioxidant activity and minerals (Na, K, Mg, Ca, Fe). The color parameters for bread and muffins were quantified in terms of L* (lightness), a* (redness/greenness) and b* (yellowness/blueness). There was an increase in a* and b*, while L* values decreased. Tomato based bread and muffin were found to possess softer texture as compared to control products. Microbial study has depicted the enhanced shelf-life of tomato based bread and muffin. Shelf life of preservative added tomato based bread was 8 days and muffins were 12 days. Tomato pomace could be a very useful commodity for incorporation into bread and muffin to have a complete nutritive food product.

Project description:The conservation and characterization of landraces have key roles in the safeguarding and valorization of agrobiodiversity. Indeed, these plant genetic resources represent an important crop heritage with quality and sensory characteristics that can be of great use to consumers and industry. In addition, the preservation of genetic resources from the risk of progressive genetic erosion, and the enhancement of their potential can contribute to food security and improve the nutritional value of food. Accordingly, this study aimed to investigate a collection of Sardinian tomato landraces for parameters that have determinant roles in evaluating their responses to conservation, and therefore to consumer acceptance. Six Sardinian landraces and two commercial varieties were cultivated in a two-years off-season trial, harvested at two different maturity stages (turning, red-ripe) and characterized using 14 fruit-related quality parameters that define the marketability, nutritional value, and flavor of the fruit. Data were collected at intervals of 10 days, starting from the harvest date and over 30 days of storage under refrigeration. The simultaneous analysis of all the qualitative characteristics for the different genotypes allowed to clearly differentiate the local varieties from the commercial varieties and a few landraces emerged for their satisfactory performances, e.g. "Tamatta kaki" ad "Tamatta groga de appiccai". In particular, the "Tamatta groga de appiccai" showed satisfactory lycopene content at marketable stages (average 5.65 mg 100g-1 FF), a peculiar orange-pink color with the highest hue angle values (range: H°T0 = 72.55-H°T30 = 48.26), and the highest firmness among the landraces of the red-ripe group (range: EpT0 = 1.64-EpT30 = 0.54 N mm-1). These results highlight the potential of some of the Sardinian tomato landraces for developing new varieties or promoting their direct valorization in local markets and could considerably increase the effectiveness and efficiency of agrobiodiversity conservation strategies.
