An Analysis on Quality, Colour, Tissue Texture, Total Soluble Solid Content, Titratable Acidity and pH of Santol Fruits (Sandoricum koetjape Burm.F.) Merr. Pui Fai Cultivar, Grown in Northern Thailand

Abstract

This laboratory experiment was carried out at the Department of Agricultural Technology, Mahasarakham University, Northeast Thailand during June to October 2007. The experiment aimed to search for the most appropriate harvesting age of fruits of Santol orchard plants with respect to colour, tissue texture, total soluble solid content, titratable acidity and pH of Santol fruits. A Randomised Complete Block Design (RCBD) with four replications was used. Each replication consisted of 10 fruits, thus a total of 160 fruits were used. The Santol fruits were harvested at different ages, i.e., 100, 115, 130 and 145 days after full bloom of flowers and these harvested ages were used as treatments, i.e., 100 for T1 (Control), 115 for T2, 130 for T3 and 145 for T4. The results showed that the most appropriate harvesting date for high quality Santol fruits was found with T4, i.e., 145 days after full bloom of flowers where Santol fruits of T4 gave the highest mean values of fruit length, diameter, fresh weight fruit(-1) of 10.71 cm, 9.31 cm and 399.76 g, respectively. Yellowness of skin colour of fruits was evenly distributed. Total soluble solid content of pericarp, flesh tissue and seeds were highest for T4 with mean values of 13.93, 15.05 and 18.260 brix, respectively. Flesh texture density highly decreased with an increase in numbers of days after full bloom of flowers. Titratable acidity content in fruits was highly decreased with an increase in numbers of days after full bloom of flowers whereas a reverse was found with pH of fruit juices.

Caracterização físico-química e determinação qualitativa de enzimas Polifenoloxidase e catalase nos frutos de Santol (Sandoricum Koetjape)

“…Os valores encontrados demonstram que a amostra da polpa de santol analisada apesar de apresentar um pH com valor baixo, não demonstrou um teor de acidez elevado. Ademais, os valores obtidos foram similares aos encontrados por Chutichudet et al (2008). O teor de sólidos solúveis foi superior ao encontrado por Benjawan & Chutichudet (2009), sendo esta diferença justificada pela condição de armazenamento e período de estocagem da amostra.…”

“…As frutas de santol geralmente são consumidas frescas e utilizadas para a produção de doces, geleias e produtos de confeitaria, assim como na elaboração de bebida alcoólica fermentada (Rasadah et al, 2004;Morton, 1987). Ademais, os frutos de santol apresentam em sua composição grande quantidade de antioxidantes, como betacaroteno, substâncias bioativas e flavanóides, além de alta concentração de vitamina C (Chutichudet et al, 2008). Esses compostos possuem nutrientes com propriedades antioxidantes, anti-inflamatórias, anticancerígenas e capacidade de combater doenças cardíacas-coronárias (Rasadah et al, 2004;Benjawan & Chutichudet, 2009;Chutichudet et al, 2008).…”

Os frutos escurecem com facilidade provavelmente pela presença de enzimas oxidativas.…”

The health benefits of santol fruits and bioactive products isolated from Sandoricum koetjape Merr.: A scoping review

“…Santol plantations are important in Thailand and the Philippines. The culture conditions and harvesting processes have been optimized (Chutichudet et al, 2008). Mature fruits exhibit major antioxidant activity due to the presence of polyphenols and vitamin C (Benjawan et al, 2008; Benjawan and Chutichudet, 2009).…”
