PLANT – BASED SQUALANE COMPOSITIONS FOR APPLES AND PEARS TO REDUCE SURFACE SCALDING
Surface scalding is a physiological disorder occurring mostly in apples and pears. It is one of the most common problems during post-harvest and storage, as well as being the cause of rejection of these fruits by international shipments. University of Talca research team, led by Carolina Torres, PhD. in Horticulture, have succeeded in developing a new natural anti-scalding for pears and apples. Currently, a potentially
marketable formula is available in the short term for pears, 100% natural, highly effective to prevent surface scalding during long storage with beneficial effects for fruit quality and condition. Plantbased Squalane compositions for apples and pears, which help to prevent surface scalding (oxidation) of pears and apples during post-harvest and storage stage.
CURRENT DEVELOPMENT STAGE TRL 7
Validated at pre-commercial scale in operating environment. Provides greater firmness and colour to fruit. The new anti-scalding has been validated to semiindustrial scale in Chile and the United States, in pears and apples. Tests were performed under controlled atmosphere (AC) as well as in conventional cold (FC).

COMPETITIVE ADVANTAGE
Active ingredient (a.i.), plant-based Squalane (antioxidant) is readily available through identified suppliers. Low ethylene production. Preserves fruit organoleptic properties. Prevents the appearance of other physiological disorders. Highly effective preventing surface scalding (76% to 100% control) under various storage conditions for apples and pears. Additional positive effects on fruit quality (colour, firmness, lower
ethylene production, texture and overall appearance). Applied postharvest. It may be commercialized as “plant-based antioxidant coating”, potentially reducing regulatory requirements.
