Abstract

Kernel breakage is the major economic challenge for the Spanish almond industry. Thus, this study aimed to determine the kernel breakage during the shelling operation by (ii) identifying the primary breakage factors, and (ii) evaluating the impact of water conditioning on final kernel quality. Twelve almond samples, of which 9 intraspecific hybrids were specially selected to enlarge the variability range. Kernel breakage ranged between 5 and 71%, with HYB8 registering the lowest breakage values and HYB5 the highest. Cultivars, 'Vairo', 'Guara', and 'Lauranne' showed also substantial breakage rates (40, 45, and 56 %). More absorbed water (r = - 0.71**), elasticity (r = -0.60*), wider (r = -0.70*) and rounder (r = -0.65*) fruit with higher fat content (r = -0.84***), reduced breakage in shelling operation. Meanwhile, almonds with a higher shell strength (r = 0.63*), more elongated (r = 0.67*), with higher skin (r = 0.69*) and fiber content (r = 0.58*) were more susceptible to breakage. Water conditioning produced a color change in kernel, while the oil acidity was similar before and after (0.1%) the conditioning process, meaning that, this was fast and correct enough to avoid enzymatic degradation. In the absence of significant technological advancements, further research must focus on optimizing water conditioning processes and standardizing cultivars to reduce kernel breakage in the Spanish almond industry.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-04:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 4.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 4 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/20.500.12327/3496
